Ben:  In this episode of the Ben Greenfield Fitness Podcast.

The latest pro-athlete biohacking tricks, the world's first mouth-based weight loss device, the best lightbulb for sleep, early versus late dinners, and much, much more.

Health, performance, nutrition, longevity, ancestral living, biohacking, and much more. My name is Ben Greenfield. Welcome to the show.

Well, welcome to today's show, Jay. How are you doing?

Jay:  Hey, man, I'm doing well. How are you, Benjamin?

Ben:  I'm pretty good. I'm happy because I think I've really, really cracked the code on how to make an amazing smoothie after decades and decades of trying and writing cookbooks and articles about superfood smoothies and the like. You know what I think makes for a really good smoothie, Jay?

Jay:  Oh, tell me. I mean, you come up with a new smoothie, I feel like, every week, or you're perfecting one. So I feel like you've really come up on something this week and I'm excited to hear, so tell.

Ben:  Somebody even asked me the other day what my favorite food was, and I said smoothies. And they told me that's not a food. I said yes, it is. So, the trick to making good smoothie in my opinion for mouthfeel and satiety, and the overall texture of the smoothie is to allow enough air to be introduced during the blending process to where you get this nice fluffy texture on the smoothie. Because I like to mix mine super thick of course, as I've said a billion times before on the podcast, so I can eat my smoothie with a spoon like ice cream, but like thick, fluffy ice cream.

So, the trick is to put all your smoothie ingredients into the blender and then start the smoothie on a really–if you have one of the blenders that you can adjust the intensity on, like the blending speed on, start it at a really, really super low intensity. And then every 15 seconds, increase the intensity of the blending up to about the 3-minute mark. So, we're talking about pretty long blend. But by starting it low and increasing about every 15 seconds to high, you introduce air, greater and greater volumes into the actual smoothie bowl. And what winds up happening is by the end of about three minutes, you've got enough little tiny air bubbles introduced into the actual smoothie to where if you've got your ice to liquid to powder texture just right, you get this amazing fluffy, airy smoothie. It's really good.

Jay:  Yeah. So, you know what's interesting is that I have a very similar process, granted, my wife makes the smoothies most of the time. I just tell her what I want in it or she just puts whatever the hell she wants in it. And our smoothie ends up being like when we serve it to other people and they taste it, they don't describe it necessarily as much like a smoothie. They say it tastes a little bit more like a mousse. Is that how yours comes out, like a mousse?

Ben:  Yeah, exactly. That's a really good way to describe it. It's kind of like a mousse. And yeah, and then you didn't put all your toppings in and everything after that and stir those all in. The trick is you don't want to put, or you don't want to leave your smoothie in the blender for too long after you've made all that. You want to consume it pretty quick afterwards because otherwise, the air bubbles start to go away. These are all very, very important life [00:03:29] _____.

Jay:  They really are. Ben, does your smoothie when you do this, instead of being super cold, does it end up being like, not necessarily room temperature but not too much cooler than?

Ben:  Yeah.

Jay:  That's how mine is, too. And a lot of people that I–

Ben:  I like it like that.

Jay:  Me, too. My wife complains about it. She wants it cold and I prefer that moussey, almost like room temperature flavor and texture to the cold icy flavor. I don't really like cold, icy smoothies anymore.

Ben:  We are on the same page, brother. Kiss your brain freeze goodbye. Anyways though, we have a whole bunch of stuff to go over in today's podcast. This is the live Clubhouse recording. So, if you're listening to this and it is the recorded version, just know that we do these every Wednesday, typically around 10:30 a.m., or not every Wednesday, every other Wednesday on Clubhouse. So, if you want to attend and ask your questions live, you can, and we will be taking listener questions live. So, welcome to all of you, fantastic faces, who have joined us on Clubhouse. We'll be taking your questions after we kick off with some of the latest news flashes this week. And as usual, everything that is mentioned on today's show you can access over at BenGreenfieldFitness.com/432. 432 is the actual episode for today's show where the shownotes are. So, what do you think, Jay, should we jump in?

Jay:  Yeah, man. We've got a lot to cover. Let's do it.

So, this is the part of the show where everything that I talk about on Twitter, to BitClout, to Facebook, to Instagram, and beyond, we choose the sexy stuff and unpack it in this section of the show. And this was an interesting article that appeared on The Red Bulletin. And actually, The Red Bulletin is a magazine put out by Red Bull. They actually recently interviewed me. And I published the audio for that interview on the podcast last week, if anybody wants to listen in. But they've been increasingly doing a lot of articles on biohacking and technology, and some of these more advanced modalities for improving performance, or health, or sleep, or what have you.

And they published a pretty cool article called “These biohacking tricks gives the world's best footballers the ultimate kick,” which caught my eye right off the bat because I think above most sports, footballing aka European soccer tends to be ahead of the curve when it comes to using more advanced modalities for performance, or for recovery, or for sleep, or for anything else. So, what they did with this article was they analyzed some of the so-called biohacks that a lot of these professional footballers were doing. But then they ran them by a, I guess what would be considered like a professional, a person who does a lot of this biohacking and biking research. And actually, the guy who interviewed me on that podcast, a guy named Andreas Breitfeld. And Andreas is a German, which just by being German, that automatically makes him a really good biohacker, whatever that means.

Jay:  Ten extra points?

Ben:  Yeah, exactly. But I mean, he's one of those guys who's got a lab in Munich and he does hyperbaric oxygen therapy, and headbands that measure brainwaves, and red light therapy panels, and inhalation devices for structured water. And so, what the magazine did was they took a look at what a lot of these professional footballers were doing, then they ran them by Andreas, who his take was. So, a few of them are pretty interesting. The first one I thought was boring at first glance, but it's interesting nonetheless, so Robert Lewandowski, who's a striker for the Polish team. What he says is not only does he eat no cow's milk, no wheat, and almost no sugar. So, kind of like that Tom Brady-esque approach of not eating anything in your diet aside from, say, bone broth and then of course championing that as a healthy diet.

But perhaps the most interesting part of the interview with him was he said he always eats his cake before his soup, or always eats–whatever is the carbohydrate content of his meal, he eats first with the idea that you digest carbohydrates more quickly than protein. So, it will aid digestion to eat your carbohydrates first. Now, the commenter on this article says that there might be something to this because the glycogen stores in your liver, if you're a high-trained athlete or kind of empty. So, they just soak up all the carbohydrates and then you eat your high-grade protein and your good fat. I actually think that Mr. Robert Lewandowski is making a mistake with this particular tactic of eating the carbohydrates as the very first part of the meal. You know why that is?

Jay:  Yeah. Well, I mean, I have my own theory, but I'd love to hear what you would state and then I'll say if it's different.

Ben:  My theories are probably the same, and that is that multiple research studies have shown that by consuming protein, fat, and fiber early in a meal, you slow the glycemic index of that meal and make the carbohydrates that you're about to consume be released as sugar into the bloodstream more slowly. Which again, if you're an athlete and you've been working out all day like a soccer player does, probably doesn't matter. But if you're the average person, you actually should eat the protein, fat, and fiber portions of your meal, or at least the lion's share of those early in the meal because it allows you to have a better blood glucose response to the carbohydrates. So, basically, don't eat your dessert first or any other carbohydrate-heavy portion of the meal first.

Jay:  Yeah. No, that's exactly what I was thinking as well. And the other thing too, I really wonder if this guy, Robert Lewandowski, if he just really always wanted to do this as a kid and his parents always told him, “No, you can't do that. You have to eat your food first and then you get your cake.” And then finally, he was like, “I'm a man. Screw you, I'll do what I want.” And so, he went through his cake first.

Ben:  Yeah. Well, A, Robert Lewandowski would be such a better soccer player if he decided that he would eat his soup first and then his cake. And B, I do break this rule sometimes because there's this wonderful restaurant that I eat at in Spokane called Baba's. It's a Mediterranean restaurant. I love that place. I go to it once a week. But they don't take reservations. However, they're right next to another local place that I really like called The Scoop, which is a gelato store, gluten-free vegan gelato flavors made out of coconut milk. And they always have these wonderful recipes like mud pie and vegan strawberry cheesecake. And sometimes if I show up to Baba's and the wait's like an hour, I'll go have ice cream and go for a walk while I'm waiting for my table.

Jay:  You, dirty cheater you.

Ben:  Yeah. Alright, but we digress. Erling Haaland, his was kind of boring. He wears blue-light-blocking glasses. We've already established that's probably decent idea. Just don't wear them when you're playing soccer. Another guy named Zlatan Ibrahimovic–

Jay:  You got it right, Ben.

Ben:  That's quite right. He is into Wim Hof style cold therapy and talks about how he spends three minutes in a mobile deep freeze. He has a cryotherapy chamber that he and the team actually travel with. And the advice from Andreas, who they interviewed afterwards, was for him, if he wanted to gain muscle mass, to not go into the cold straight after working out and to save the cold for later. What do you think?

Jay:  Yeah. I mean, you don't want to blunt the hormetic response to stress that exercise induces. So, I would agree with that. Would you disagree, Mr. Ben?

Ben:  I would disagree because this is blown way out of proportion. So, this idea behind avoiding antioxidants after you exercise so that you don't blunt the hormetic response to exercise, or the ability to build mitochondria post-exercise. Or for example, the idea that if you want to build muscle, you shouldn't get cold after workout or visit the cryotherapy chamber. Well, in fact, the drop in core muscle temperature that has to occur in order for those adaptations to be blunted in response to cold, it takes like 10 minutes of extreme cold for that to happen. So, basically, if you're doing a cold shower or a three-minute cryotherapy chamber, cold soak, whatever, the drop in core temperature is actually pretty advantageous for recovery, especially if you're doing a training session, let's say in the three hours leading up to bedtime.

As a matter of fact, unless you're getting incredibly teeth-chattering cold, you really don't run much of a risk of blunting the hormetic response to exercise. And they've measured the actual decrease in muscle core temperature that's required, and something like 3 degrees Fahrenheit, which requires a pretty hefty amount of cold for a long period of time to be able to achieve. And similarly, with the antioxidant piece, you got to go super high dose vitamin E, or super high dose vitamin C, or both from a synthetic vitamin E or vitamin C source in order for those adaptations to be blunted. So, a lot of people see the research and they think they can be super smart and sciencey and not do any of this stuff post-exercise. But ultimately, it's not as important as a lot of people think it is.

Jay:  Yeah. No, I think that makes a lot of sense. For me, I guess when I think about actually doing cold therapy to me, obviously, I'll take cold showers. I don't do much cryotherapy just because I prefer to take an actual cold plunge, a 5 to 10-minute cold plunge. And from what you're saying, the cold shower or doing the cryotherapy may not have as much of a deleterious impact on muscle protein synthesis and so forth moving forward as, say, getting in an actual cold plunge for an extensive period of time. Like you wouldn't jump in your Morozko after you're done with your training as compared to like you would jump in a cold shower or jump in a cryotherapy–

Ben:  No, I jump in the Morozko, which is 32 degrees. I just wouldn't stay in there for 10 minutes. And again, the drop in core temperature that might assist with sleep later on, and also the fact that you're not going to be pitting out at dinner and annoying all your friends by smelling funky, I think it's worth it to do cold. I think a nice splash of cold plunge workout is worth it, and most people are under a faulty impression that it's going to blunt any response.

Alright, so let's do one more. Cristiano Ronaldo, a great famous European footballer. He says that he takes six 90-minute naps over the course of 24 hours, which if you do the math means that he's spending like 9 hours of a 24-hour period napping. I don't know if that's like on the regular or if he said that to the interviewer because that's maybe something he does when he travels, because he also says he eats a total of six meals on each of those days too, like breakfast, and two lunches, and a snack, and two dinners. And I'm like, “Dude, how's this guy been trained? All he's doing is sleeping and eating.”

So, they ran it by this guy Andreas, who says that this idea of what's actually called polyphasic sleep is wonderful and well-researched, but that the downside is that nobody can keep it up. That is difficult to combine disappearing six times a day at an exact time, and to do that and have like a vaguely normal working life or a halfway bearable family existence. I think that that's pretty much the general consensus that I've also heard about polyphasic sleep is to get you through a period of time of sleep deprivation or really weird schedule, there actually is research to show that just by napping a whole bunch of different times over a 24-hour period, you can get by just fine without doing a longer sleep period.

But kind of like, let's say, I don't know, the carnivore diet. It's incredibly socially restrictive to have to just put everything down and nap every few hours. However, napping in general, there's a lot to be said for it, and this idea of polyphasic sleep, if you are going through a period of time or, I don't know, you're launching a new business or, I don't know, your crypto coin has an ICO, or you're a professional athlete traveling around the globe and don't have enough time to get a proper sleep schedule in, it can work. It's just pretty unsustainable for long periods of time. In my book “Beyond Training,” I explored all these different so-called uberman or polyphasic sleep schedules. And basically, what I came out with was here's how to do it if you're going to do it, but it's not that sustainable for long periods of time.

Jay:  Right. No, indeed. It's interesting. I would be very interested to hear how often he actually does this, because again, yeah, it does restrict a lot of things that you can do in life and doesn't seem sustainable on a week-to-week basis. Also, Cristiano Ronaldo is one of those individuals who's highly trained, he's highly efficient with his performance, and he's like a huge influencer, and affiliate, and sponsor, very active on social media. So, I'm like, “I mean, is he actually doing this that often or is he just saying like, ‘Every once in a while, once a quarter, maybe I'll do this?'”

Ben:  I know. Media, right? It's one of those sexy things that appears in an article, but you wonder if that's something that he does on the regular, even though the caption underneath the little cartoon image of him sleeping says, “Ronaldo takes six 90-minute naps before big games.” Six of them, [00:17:04] _____.

Jay:  I mean, what is considered a big game. They play like once or twice every single week. So yeah, come on.

Ben:  Yeah, it doesn't seem that's sustainable. Anyways though, I'll link to the full article in the shownotes over at BenGreenfieldFitness.com/432 for anybody who wants to read it.

Another paper that came out that was related to something that I've harped on for a while, and that's this idea that science is sexist. And what I mean by that is this particular article got into the idea–it was published in June of 2021, but it was on molecular omics. Now, that might seem like a mouthful to a lot of people, but basically, what they looked at was molecular cellular and what's called organismal biology to investigate whether there are an appreciable amount of hormonal, and molecular, and metabolic differences in males versus females, both animal and human, that would dictate what is predominantly research done on male rodent models and male humans. I don't know if you really differentiate that much between like male yeast and female yeast or male fruit flies and female fruit flies. But essentially, it's all skewed like 80% towards males.

And the problem with that is that due to the difference in XY chromosomes that there are appreciable differences in terms of genetic expression, in terms of endocrine expression, in terms of gonadal and adrenal steroid hormones, and even response to certain environmental exposures that would dictate by us not paying attention to sexual differences in males versus females in most of the research that we do on everything from pharmaceuticals to supplements, to nutritional protocols and beyond dictates that a lot of biological research has quite a bit of bias in it. And in fact, sex actually does matter.

Now, this paper backed that up and made an argument for a little bit better job, including consideration of sex and gender in research. But it is actually true. Not only are most of the researchers themselves male, but these subjects that are often used in many of these researchers are also male. And when you're reading a research study, a lot of times, even the abstract will not report the male versus female subject breakdown. And the complaint among researchers is that if you were going to actually allow for sex differences, that it would be problematic from an expense and a logistical feasibility standpoint for studies because they would need to introduce a whole new kind of like N or subject body as far as allowing for a male subject group versus a female subject group.

But in fact, contextualism does matter heavily when it comes to sex-related variables. And furthermore, you can change the scientific model a little bit to break out male versus female subjects and still get some pretty good data. But ultimately, it returns back to something I've harped on over and over again, like we need to not have women's health science be an afterthought. We need to actually take into account the unique endocrine system, and hormonal response, and all the other variables, the gender-related variables that go into species varying by sex in response to nutrition protocols, and fitness protocols, and supplementation protocols, and a lot of the things that we look at in physical culture research. And it is kind of sad that we still do the lion's share of research by males, on males, when in fact, female biology is so much different in so many scenarios.

Jay:  Yeah. No, it's a great point. One of the things that I do when I'm reviewing any type of literature, mostly daily, is I'll always look at the footnotes or look at the challenges, future directions for research, and it's such a commonality to see that as problematic within the research study. The researchers indicate that it was heavily influenced by male bias because that's all we looked at were males. And when you look at athletic studies and performance studies, that's when the skew even goes more positive towards male inclusion. So, no, I completely agree with you that that's something that just tends to be overlooked.

And of the things that I–I was actually reading an article about this not too long ago, is that they said that some of this bias comes because it was so heavily promoted for the last few decades that males go into the world of research, they're dominated in the research world, but we're seeing that flip a little bit. And now that we've got some more women within this field who are providing their voice, they're not going to let that one slip through the cracks. So, hopefully, that will change over time, but yeah, we've got to keep continuing to push for it.

Ben:  Yeah. And in this particular study, they highlighted that in over 100,000 humans, there were 13 different complex phenotypes or variables in terms of the way that genetics were expressed that displayed genetic what's called heterogeneity between males and females. And the genomic prediction model that they used using sex-specific models heavily outperformed any sex agnostic model. Meaning, essentially, just turn back to what I had pun earlier like the vernacular here would be sex agnosticism in research is not doing us any favors. And I'll link to possibly a boring sleeper's paper for a lot of people, but it's called “Molecular omics research should require sex annotation,” to basically, don't ignore the checks, people. So, there you have it.

Okay. So, another really interesting one was a study that looked at organic light-emitting diodes. If you're not familiar with these, they're abbreviated OLEDs. And I've said this in the past and even in “Beyond Training” and “Boundless,” my book “Boundless.” In the lighting section, I do highlight the fact that these newer organic light-emitting diodes as a lightbulb option, they emit less blue light than traditional light-emitting diodes. And this study found that the use of OLED light versus LED light at night was better at mitigating the suppression in melatonin that occurs in response to LED exposure.

Now, that being said, if you were going to look at getting a lightbulb for the majority of cans in your house, incandescent is the form of lighting that despite requiring a little bit more power, so your power bill might go up just a little bit, is the most compatible with the human biology and the form of lighting, incandescent lighting, is the form of lighting that most closely simulates the full spectrum of what sunlight would give you. Now, furthermore, something that's important to realize is that the lower the wattage on your bulbs that you're using, like if you're using 25 or 50 or 75-watt bulbs, the problem with those is that in order for the bulb to produce less light like that, it has to produce more what's called flicker, which is this imperceptible on/off, on/off, on/off that can lead to not only disruption in circadian rhythm, but also some irritation to the retina that results in things like brain fog, a little bit of headache towards the end of the day, et cetera.

So, the best way to go would be to go anywhere from like 100 to 250 watts. Go for OLED or incandescent. And even if you're going to have LED, try to choose more of a flicker-free LED bulb. There's very few LED bulbs that are flicker-free. Brian Hoyer, who has been a previous podcast guest of mine, who owns the company Shielded Healing, and he does building biology walkthroughs of like offices and homes. He says there's one brand you can get on Amazon called Sunlite and they're non-dimmable orange, or yellow, or red bulbs that are LEDs. So, they don't have the full spectrum of infrared like, say, an incandescent was, but A, you don't really need your full spectrum of infrared necessarily if you're already using like near-infrared, or far-infrared panels, or red light therapy, or something like that.

And furthermore, if you're just trying to block blue light at night, then these type of Sunlite LED bulbs or OLED bulbs, if you're trying to avoid the expense of incandescent, are probably just fine. But again, you still want to make sure that you're not doing the super-duper low like 60 watts, for example, that produces this 60 Hertz flicker, and that you're going for essentially 100 watts or more. There's even like these sauna space bulbs that they sell for the sauna. And those produce a lot of heat, so a lot of people don't like them, but those are like 250-watts photon bulbs that block out all the blue light.

So, if you want to go for a really, really high wattage light, you go with something like a sauna space. If you want to go for slightly lower wattage, you could go with something like these Sunlite bulbs. And if you just want to go gold standard, and this is what I do in my house, it's all incandescent and red incandescent. And then it turns out that if you can use these OLED bulbs based on this most recent research, that's not a bad option either for circadian rhythm or sleep, these organic light-emitting diodes.

Jay:  Yeah. No, it makes total sense. One of the things that I have actually thought about when I was reading this is that the current iPhone–and I believe most phones now use OLED screens, and a lot of TVs now have OLED screens in them. So, I don't want people to confuse this with, hey, I can now use as much OLED and iPhone screens at night as I want to. That's not what this report is saying or the study is saying, but it's really good just to be conscientious of overall lighting, but especially just the type of bulbs because bulbs aren't necessarily made the exact same as you mentioned.

Ben:  Exactly. So, I'll link to that one as well if people want to review it.

And then, we're kind of bouncing around all over the place here as far as some different topics for research papers, but this one was really good, too. It was a new article that came out on aging protein and amino acids. So, what the article was going into was the idea of the protein paradox, which many people I think are now aware of that basically, as you reach old age, we're advised to increase protein consumption to stave off muscle loss, to stave off sarcopenia, to get adequate amino acids. But at the same time, protein seems to activate aging pathways. And protein and amino acid restriction seem to often have these life-extending type of effects.

So, there was this study that looked into the different amino acids and how they have different effects on various aging pathways in your body. And the idea is basically, well, how can you get enough protein to be able to have things like a functional muscle mass as you age and to stave off muscle loss that would produce frailty or fragility with age, but not have so many amino acids going into your bloodstream that you are depressing lifespan through excess activation of mTOR? So, what it turns out to be is that there's two different forms of amino acids that if you restrict them, seem to extend lifespan. The first is methionine, and the second one is tryptophan. So, methionine restriction is something that's been used in cancer therapy. It's something that seems to be a fingerprint of extreme longevity, especially in human centenarians. It increases fat oxidation when you restrict methionine. It lowers liver lipids when you restrict methionine. And then, tryptophan, you also see a delay in physiological decline when you restrict tryptophan, a reduction in tumor formation, and also a better cognitive function with age.

Now, at the same time, there are certain amino acids that seem to increase lifespan. For example, glycine. Glycine supplementation increases lifespan. Glycine supplementations decreases chronic inflammation. Basically, glycine prevents the mitochondrial dysfunction that comes with aging. And so, glycine is an amino acid that, unlike methionine and unlike tryptophan, seems to have a life-extending type of effect. And another one that seems to actually be deleterious for lifespan would be branched-chain amino acids, which again can prevent some amount of muscle wasting and are very popular as a weight training supplement. But the high levels of leucine, and isoleucine, and valine in branched-chain amino acids seems to actually be one of those things that especially in excess could shorten lifespan.

So, it's very interesting though when you look at methionine, and at tryptophan, and at branched-chain amino acids, well, where do you get the majority of these in two things that people seem to be consuming a lot of in a modern Western context, which is like protein powders, meal replacement drinks, BCAA supplements, and meat? The same type of muscle meat that our ancestors would have given to the dogs in favor of things like the organ meats, and the bone marrow, and the bone broth, and the fats, and the collagen, and the knuckles, and all that jazz. Basically, we're doing the complete opposite now. Like, we don't eat a lot of organ meats. Painting with a broad brush for the most part, most people don't eat a lot of bone marrow, bone broth, organ meats, et cetera. We eat the muscle meat that's really high in methionine and tryptophan. And then, bro, we suck down our protein shake or our BCAA supplement on the way to the gym.

And so, the form of protein that we tend to get in most cases, unless we're aware of this type of research, is the type that does actually decrease lifespan. Whereas if you're doing like bone broth, bone marrow, doing more of like essential amino acids instead of branched-chain amino acids, eating your organ meats not to an excess ribeye steak, but maybe instead of those ribeye steaks, you're doing a couple nights a week, you're instead doing a big cup of bone broth, a little bit of liver, or heart, or kidney, or bone marrow, or something like that, there's just basically two different ways to optimize your protein intake. And weight 1 decreases lifespan, and weight 2 doesn't seem to do that.

So, basically, what this should inspire people do is step back, look at your diet, look at your protein intake. And yeah, not only have certain days of the week or certain periods of the year where you're engaged in some amount of protein and amino acid restriction but ensure that the lion's share of the protein sources that you do eat are more of like a nose-to-tail approach, somewhat low in the muscle meats. And then, for your supplements, try and cut out the supplements that tend to have these BCAAs added to them. And instead, favor supplements with a more complete amino acid profile, and especially supplements that might include, for example, things like glycine or some of the amino acids that are aside from the methionine and the tryptophan, particularly.

Jay:  Yeah, super interesting. With methionine and BCAAs, those are the two that I'd really harped on and heard in the past and makes a lot of sense. The one that I have thought was quite interesting is I had not heard about how tryptophan restriction can extend lifespan. And this is a really important one and an interesting one for me because I have so many people who email me or write me because of my background obviously as a psychologist. And they hear about people taking tryptophan, L-tryptophan, 5-HTP for serotonin synthesis because it is a precursor to serotonin, and also melatonin obviously as well. And so, it's interesting because, for me, I'm always like, “Let's get it in from a dietary regimen if we can.” And obviously, it's saying here that we might be eating too much tryptophan within the diet framework. So, it's one of those things just to keep in mind because I know so many people nowadays are trying to supplement with tryptophan, with 5-HTP, and I think that it can have some positive effects from a mood-based standpoint. But if we're looking at longevity, anti-aging, it may not prove to be as worthwhile on that end. So, that was an interesting one to me.

Ben:  Yeah. So, hopefully, that's an eye-opening for people when it comes to your protein and your amino acid consumption. And again, I'll link to that one as well at BenGreenfieldFitness.com/432.

Okay. We talked about lighting. And this one was interesting because kind of related to the lighting concept, the name of this recent paper was “The efficacy of combined bright light and melatonin therapies on sleep and circadian rhythm.” Now, in the past, I've talked about how one of the best ways to reset your circadian rhythm or to shift your sleep cycle forwards or backwards is through the strategic use of light. Meaning that if I'm waking up at 4:00 a.m. in the morning, and that's annoying to me, and it's too early, and perhaps I've been traveling back east, which is why I'm waking up at 4:00 a.m., but now I'm back on the Pacific Time zone and I don't want to wake up that early.

Reasonable strategy is to, when I wake up at 4:00 a.m., even if I am not staying in bed and I'm getting up and getting some things done because it's annoying to just lay there for a couple hours and stare at the ceiling, is to keep yourself in a somewhat dark environment. Wear blue-light-blocking glasses the same that are typically recommended for you to wear at night, but wear those in the morning. Avoid looking at bright screens. Avoid even things like sunlight exposure until the time arrives when you actually want to start waking up like, let's say, 6:00 a.m. And at that point, blast yourself with light, get out in the sunlight, take off the blue-light-blocking glasses. Take your phone out of red light mode and switch it to full light mode. Flip your computer monitors on and blast yourself with light.

And that actually works very, very well to shift that circadian rhythm forward. And the same could be said for if you're waking up super light, you'd shift towards setting your alarm a little bit earlier, but then blasting yourself with light after that alarm goes off. So, you're beginning to phase shift backwards your circadian rhythm. Well, what this recent paper looked at was using this strategy that I've just described for the most part, but then also combining that with melatonin in the evening. And what they found was that when it comes to shifting your circadian rhythm, specifically advancing your circadian rhythm, meaning, allowing yourself to get up later and go to bed later, which would be such as you might want to do if you have been used to being somewhere in an Eastern Time zone, but now you're in a Western Time zone and you need to shift everything forward a little bit to better mimic what you're experiencing in that Western Time zone. That by doing the bright light exposure at a certain point during the day, preferably in the morning when the time has arrived that you want to start getting up and then taking melatonin about 30 to 60 minutes prior to when you want to go to bed at night, that actually is a better strategy than what they looked at in this study, which was doing that light trick all by itself.

So, what that means is if you combine the lighting adjustment in the morning with melatonin supplementations at night, it has an even better effect at shifting your sleep-wake phases. So, it's kind of like a one-two combo for travel, for jet lag, for circadian rhythm adjustment, is to actually combine the circadian rhythm with the melatonin. Now, in this case, they weren't using like the sledgehammer of melatonin that I was talking about, like when I interviewed Dr. John Lieurance, for example. Yeah, I believe they had somewhere in the range of like 0.3 to 3 milligrams, like a more standard dose of melatonin.

But it turns out that again, light in the morning or in the early hours, melatonin in the evening hours, again for this paper, it was more for shifting the circadian rhythm forward. It would probably also work for shifting the circadian rhythm backwards as well. Meaning that you could use the light earlier in the day and the melatonin earlier in the day versus the light a little later in the morning and the melatonin a little later in the evening. But either way, that one-two combination of light and melatonin seems to do a really good job at shifting your circadian rhythm.

Jay:  It's interesting. I have a love-hate relationship with melatonin because every time I used it, whether it's in a small dose or a high dose, man, I always wake up groggy the morning after melatonin.

Ben:  That's not uncommon at all. And the trick for that, if you use melatonin and it makes you wake up groggy, is to get as much sunlight exposure as you can in the morning because–for the same reason that it's a good idea to avoid a lot of bright light at night because it suppresses melatonin production. Basically, it just blasts the melatonin out of your system more quickly when you get a whole bunch of light exposure in the morning after you've taken melatonin the evening before. So, that's the best way to get over melatonin grogginess is light.

Jay:  Yeah, that makes sense. So, now that I'm doing a fair amount of Zone 2 training, and I like to do it in the mornings, like getting out and getting some just blasted with son while exercising it's like the best one-two combo. So, maybe trusting melatonin and see if that will help with eliminating that grogginess because that's the thing. It's just a pain in the ass sometimes, waking up and being like, “Well, I've got to sleep well, had a great night's rest, but now I feel like I'm not necessarily ready to take on the day.” I'm like, “Yeah it's kind of counter.”

Ben:  Yup, exactly. Alright, so a couple more quick ones before we take a few listener questions here related again to sleep. A new paper on the effects of dinner timing on sleep stage distribution. Now, what this study looked at was whether shifting dinner from five hours before sleep to instead being one hour before sleep would affect sleep disorders, or sleep regularity, or sleep quality because we've been told many times, probably with Dr. Satchin Panda being at the forefront of this research, that by eating too close to bedtime, we can disrupt sleep. And in fact, many people now will champion finishing dinner anywhere from three to five hours before bedtime, which I don't know anybody who goes out to restaurants at night, who actually does that, but let's say that, then you're getting a better sleep.

And this study found that that wasn't really the case. They did find that the late dinner was actually associated with more deep sleep in the beginning of the night and more light sleep in the latter part of the night. And they called this postprandial hypersomnia. Meaning, you actually fall asleep better when you've had a slightly later dinner, but maybe the sleep later on might not be quite as good, especially if you're looking for deep sleep. But ultimately, if you dig into the paper, there wasn't that big of a difference between eating dinner five hours before bedtime versus eating dinner one hour before bedtime when it comes to sleep architecture.

Now, here's the problem is that it was a pretty slow number of subjects in the study. It was like 20 adults. But I've found this vary so much from person to person, like athletes who eat an early dinner, their sleep totally goes to pot, totally sucks. They hear about all this research, someone who's exercising. Or not even necessarily an athlete, but just somebody who exercises more than the average lab coat-wearing scientist who's standing in the lab all day, eats dinner at 4:00 p.m., then sleeps like a baby when they go to bed at 9:00 p.m. or whatever.

Somebody who's doing CrossFit, somebody who's hitting the gym, especially like after work during the day, somebody who likes to lift weights, somebody who's bodybuilding, maybe a triathlete, all those kind of people, they burn through enough calories to where if they finished dinner at, let's say 5:00 p.m., by the time they go to bed at 10:00 p.m., hypoglycemia and low amounts of amino acids, and often just like low blood sugar and low nutrient partitioning overall becomes such an issue that sleep sucks in the same way that anybody who's been on like a fasting protocol knows that sleep just sucks. And a lot of times, the amount of CBD and melatonin, all the other sleep support stuff that you have to take in order to actually sleep because you're depriving yourself of food in the hours leading up to bedtime, leaves you just as groggy with just as poor sleep architecture as if you just had a freaking meal before you go to bed to top off your energy stores.

So, I find that it's kind of like the ketogenic diet. Most of the research on the ketogenic diet that shows that 30 to 50 grams of carbohydrates has all these healing effects and is good for epilepsy, and attention span, and decreased inflammation, et cetera. It's done in relatively sedentary subjects. And when you extrapolate that to the general population, it turns out that a better variant of a ketogenic or a low carb diet is like 100 to 300 grams of carbs per day, not the paltry 30 to 50 that are used in research for management of medical conditions. And the same could be said for a lot of this research on whether or not you should eat a dinner or not eat dinner within a few hours prior to sleep.

Basically, what it comes down to is if you're going to bed and you're burping up your food, and you have the meat sweats, and you're picking like meat out of your teeth, and you're just like groaning from a full food baby in your stomach, yeah, your sleep is going to suck. But if you're laying there and you're chewing the insides of your cheeks and can't even remember what you had for dinner because it was so many hours ago, and you feel hypoglycemic, and you lay awake, and all you can think about is like a giant roast chicken as you're falling asleep because you're so freaking hungry, then that's a sign most likely, especially psychosomatically, that you should have had more food before bed.

And I don't know about you, Jay, but for me, my sweet spot is like a huge glorious dinner that I finish typically about an hour and a half, sometimes two hours before bed, and I sleep like a baby with that scenario. And if I eat dinner at 5:00 p.m. and then have my usual 9:30, 10:00 p.m.-ish bedtime, my sleep absolutely sucks because I'm hungry. So, ultimately, it really matters on your activity levels, on how much you're eating for dinner, on a whole host of factors. And studies like this just back up the fact that it's not the same for everybody. And most people I think sometimes shoot themselves in the foot from a sleep standpoint by having what I would essentially classify as like an afternoon dinner and then not eating anything until they go to bed.

Jay:  Yeah. Those were some of the exact thoughts that I had when I read this because I thought about a couple of things that I wanted to highlight. So, kind of like you, I try to eat a little bit later in the evening. However, it's really hard with little kids. I mean, I have a three-year-old and a one-year-old. And so, they go to bed really early and we like to do a family dinner. But my wife and I have just made the decision to shift back our eating a little bit later even though a lot of times, it's like after they go to bed. So, sometimes it can be a little bit too late. But with family, you have to give and take.

But one of the things that I thought about here is just, yes, the wide amount of variance that's going to occur from individual to individual depending on their activity level, and then other host of different variables. One of the big ones here is that they're just looking at sleep architecture. So, they're just looking at the sleep stages. They're not looking at things like heart rate. They're not looking at things like heart rate variability or nervous system functioning, which actually, interestingly enough, when you peruse the interwebs and research on heart rate variability with meals, especially how it affects sleep is one of the things that we've seen is that individuals who are more highly active and engaged throughout the day, let's say like the CrossFitter or somebody who's training throughout the day, or at least largely in part of the day, is that we see these individuals actually when they eat closer to bed like that, they have that before bed snack or there's not that five hours before bed, we see their nervous system is better regulated.

But the sedentary individual, if they eat too close to bedtime, we actually see dysregulation in their nervous system doing the exact same thing as what the other individual did. But again, the activity level in the one individual compensates for nervous system regulation more so than the sedentary individual. So, it's know thyself and know that they're just talking about sleep architecture and very basic population or sample that they studied.

Ben:  Yup. That about wraps it up, man, for sure. And by the way, should you be concerned about the effects of poor sleep on something like weight gain or weight loss? I should note that one last thing I wanted to mention before we take a few questions here from our live Clubhouse audience is that researchers have developed the world's first mouth-based weight loss device. Did you see this, Jay?

Jay:  I did. It's amazing.

Ben:  It's called the Dental Slim Diet Control. I'm going to link to it in the shownotes. It's an intraoral device, typically fitted by a dental professional to your upper and lower back teeth. It's got magnetic implants in it that have locking bolts that only allow you to open your mouth about 2 millimeters. Thus, restricting you to a liquid diet, but allowing for free speech, and also ensuring that you don't suffocate because there is no restriction of breathing. It's essentially like–what do you call those things, chastity belts?

Jay:  Chastity belts, yes.

Ben:  It's like a chastity belt for your mouth. It literally locks your mouth shut. Your surgeon or whoever installed it is the person who has to loosen the device and get it off your mouth. So, basically, what it does is it causes your mouth to be so–I bet people who are into mouth taping at night and nasal breathing would really dig this thing. It'd just force them.

Jay:  My first thought is, yeah, it's going to force them to breathing.

Ben:  Right, exactly. So, it just locks your mouth shut, kind of like that gut surgery like the gastric band where it just locks your gut shut. This locks your mouth shut. So, for all you people who can't keep your gaping maw shut, who have no self-control, who can't walk past the Cinnabon without whipping out your wallet, well, we have the solution for you. The world's first weight loss device that literally locks your mouth shut was a giant silver clamp installed by a physician. And you, too, can now walk around happy and confident that you've got six-pack abs, low body fat percentage, a diet that you can adhere to because you can't open your mouth. And just the confidence, you can function well in society. You won't be able to talk, but you can function well in society with your mouth shut and your jaw thrust forward because you can't eat if you wanted to, baby.

Jay:  As long as they're mercury-free, I might go for this. Give it a shot. I'll report back for the sake of science.

Ben:  Good point. You might have some heavy metals in your mouth, but check that out folks. I know I'll be a user/investor. The world's first weight loss device. So yeah, that's not going to happen anytime soon. Just have some self-control.

This podcast is also brought to you by Ra Optics. You may have seen what I call birth control for your head. These blue-light-blocking glasses that, sure, protect your eyes from the harmful effects of blue lights and help you with your circadian rhythm and your sleep, but they're just ugly as hell. So, one of my friends actually launched a blue light blocking glasses company, but he's in the style. He used the style of Italy and the strength of Germany. Meaning, Italian acetate and German-engineered steel. Developed the most effective lens technology that exists in the blue light blocking industry. Most blue light lenses block like 3% of the harmful blue light. These things block over 95% of the most damaging range of blue light. And did I mention, they look absolutely fantastic on your face. So, you get a 10% off of these glasses. They're called Ra, Ra Optics, R-A Optics. You go to raoptics.com/ben, R-Aoptics.com/ben, and feel what the difference is when you actually have a good pair of blue light blockers.

That being said, shall we go ahead and take some questions from Clubhouse?

Jay:  Yeah, let's do it.

Female:  So, hi. I was curious in regards to the light impact on the circadian rhythm study. And I just wanted to know how it works in a longitudinal way, just because–do you have to keep exposing yourself every day or did this study talk about after you've been exposed or you've been practicing this cycle procedure, then after 20 days, or 21 days, or 3 weeks, or whatever, your circadian rhythm goes back to whatever it is that you want? So, can you touch on that a little?

Ben:  It's a great question. Cutting straight to the chase, it is shocking how quickly circadian rhythm adjustments take place. Most of the clients that I work with who travel a lot, we can shift within about two to three days using, well, what are called zeitgebers, which are the three primary strategies to shift your circadian rhythm. It's light, which we already discussed, movement. Meaning, rather than saving your workout for the afternoon, if you were trying to shift your circadian rhythm backwards, you would actually do your workout in the morning. If you're trying to shift your circadian forward, you wouldn't exercise in the morning. You'd exercise in mid-morning and late afternoon.

Then food, skip breakfast if you want to shift your circadian rhythm forward. Eat breakfast if you want to shift your circadian rhythm backwards. And preferably, if you want to shift your circadian rhythm backwards, that breakfast should also include about 30 to 40 grams or so of protein. So, light, exercise, and food are the best ways to shift your circadian rhythm forwards or backwards, and you can do it in about two to three days. So, this is a really short period of time that we're talking about in order to pull this off. So, yeah, you do not have to incorporate this strategy. Even like the melatonin sledgehammer strategy that I'll use for myself and for some of my clients where we'll do like 100 to 300 milligrams of melatonin, if we've shifted through a whole bunch of time zones, or if we're trying to fix a sleep issue, that's one to three days that we might do something like that. It's not ongoing for a long period of time at all. So, yeah, you don't have to do this stuff for long to see a pretty significant shift, but great question.

Jay:  Yeah. It's been exactly my experience.

Ben:  Yup. Alright, let's go ahead and answer another question.

Female:  I've had exactly the problem that you folks were discussing where the literature seems to tell me to eat my meal late–I mean, to eat my meal early. And I'm an athlete, so I have the hunger in the night problem or waking up really, really hungry. So, I've been trying on my own this idea of having a snack, like a six o'clock dinner maybe and then a snack, but I still seem to see like maybe the macros of what we eat closer to dinner may matter, and I haven't really figured that out. So, how might an athlete optimize their eating if they set aside the idea that the meal must be early in the evening and then nothing afterwards?

Ben:  Yeah. That's a great question. So, it's certainly something to think about. Let's say that you wanted to stave off the increase in, well, primarily, thermic effect of feeding and body temperature that would disrupt sleep from a late meal. But you're also an athlete or a heavy exerciser and you also have an issue with a hypoglycemia or low amino acid, or just the psychological hunger that occurs from restricting the size of the evening meal or shifting that evening meal to a really early time. Well, I mean, for me personally, when I've been in scenarios where I'm with people who are eating at, let's say 5:00 p.m., or I'm at a–this is what happened to me at a conference I'm teaching at for a week where all the dinners at the conference are early, early in the evening. Thus, dictating that I'm back in my hotel room after 10:00. Sometimes I'd go on a beach walk or even work out after dinner, and I'm still hungry because I've had dinner like five hours before.

Well, a slow bleed of ketones and amino acids, and even some amounts of fructose, which doesn't spike the blood glucose as high as, say, like glucose or maltodextrin or some of the other starches can be a really good strategy. So, this is where the idea of a spoonful of nut butter with a little bit of honey and some sea salt can be a really good way to enhance sleep. Or from a more advanced scientific standpoint, a shot of ketone esters with some amino acids for a slow bleed of energy into the system. Or something like a coconut oil or some coconut meats, again with a little bit of sea salt and some type of fructose-based source like blueberries or a small handful of berries, like this idea of snacking on things that allow for amino acids or ketones/fatty acids, some amounts of salts and a little bit of fructose, that's kind of the sweet spot with, to a certain extent, collagen and/or essential amino acids is pretty effective also.

So, yeah, I have certain things in my pantry that are my go-tos if I haven't had dinner very close to bedtime, but I know I'm going to be hungry or that my sleep is going to be disrupted if I'm hungry before bed. And the main things for me that I would grab from my pantry would be ketone esters, like a shot of ketone esters, a couple of scoops of Kion Aminos, that'd be another example, a little bit of like a good, raw, organic honey, a little bit of collagen, if not doing the amino acids, or a little bit of nut butter with a little bit of honey. Any of those would be something that–I mean, everything I just mentioned is like 120 calories or less, but still allows for me to get just enough to where I feel like my appetite is going to be satiated I'm not going to wake up hungry when I'm trying to fall asleep. So, those are few ideas, few things that I would use. Anything you would turn there, Jay?

Jay:  Yeah. So, one of the things that I've used plenty of times before is ketone esters. So, I actually use the KE of KE4 by KetoneAid, which is a phenomenal one for me. I do like a capful of that prior to bed. One of the things I was going to ask you, Ben–because this is something that I've been toying around with, especially when I wear my CGM or if I have a CGM on during that time. Let's say if you were to take a tablespoon or so of honey right before bed, do you see any weird fluctuations with your blood glucose during the night when you do that, like any significant drops? Or do you just stay pretty stable because you don't eat the honey naked, you take it with ketone esters or you take it with like a nut butter?

Ben:  Yeah, I definitely put pants on my honey. I rarely eat it naked. And no, I don't see any appreciable fluctuations in blood glucose because what we're talking about is a really small food intake anyways. B, I'm super-duper metabolically efficient just because I'm kind of a nutrition Nazi, so to speak, or at least many people would label me as such. And so, I don't have a lot of metabolic disruptions and responsive food intake anyways. And then, finally, like I mentioned, the fructose that is in something like a honey or a berry source doesn't cause as much glycemic fluctuation as like glucose or maltodextrin from, let's say like potatoes or cane sugar or something along those lines.

Jay:  Yeah. For me, it's just like a packaging of honey, which I do enjoy before bed, and then a little bit of ketone esters for stabilization, and I'm pretty good to go during the night. However, when my wife has done something similar to that, she'll start to see a little bit of a drop during night like blood glucose drop at night, generally around 1:00 or 2:00 a.m., and then a start–it was like a steep increase because of cortisol release. But she doesn't feel bad about it in terms of waking up and feeling groggy or feeling like she had any high glycemic variability. Just something that I didn't know if anybody else has seen before really.

Ben:  Yeah. All good points. Okay, let's take another question. Go ahead and bring somebody up to stage here.

Male:  Hey, guys. I was wondering what type of supplements you can use for high blood pressure. Right now, I'm kind of hypertensive, high at 130, but I'm taking aged garlic, and also supplement with a [01:02:56] _____. But was there anything else I could do?

Ben:  Yeah. I don't think supplements help blood pressure very much. I think most people try to pop pills for blood pressure and they never addressed the underlying issue, which is typically stress, or sleep, or fitness. So, I mean, you could pop supplements till the cows come home. And I mean, I could doctor Google for you, or you could look it up yourself, but there are so many supplements that have been looked into for a little bit of an impact on blood pressure, like magnesium, like fish oil, like garlic, like any vasodilatory product like a beetroot supplement, you name it.

You could fill your entire pantry and notice a very, very small drop in blood pressure because in most cases, a really, really good breathwork practice, especially when combined with sauna, a really, really good exercise protocol specifically in exercise protocol that trains you how to contract muscles and then fully release muscles. And there's even a health device called the Zona health device that actually works really, really well at reducing blood pressure. I've talked about it before if you go to my website and search for it. It's called the Zona. And it's literally like an FDA-cleared device for decreasing blood pressure. It's like a handheld grip dynamometer. Sunlight exposure, low amounts of stress, and a gratitude journaling, breathwork, stress reduction practice, really good sleep.

I have seen people pop garlic till the cows come home and take tons of beetroot, and ashwagandha, and herbal adaptogens, and all this stuff for blood pressure. And honestly, like until you actually, I guess address more the underlying issues, which is basically muscle contraction followed by relaxation, sunlight, heat, sleep, and low amounts of stress, you typically don't see much of an impact on blood pressure. And I mean, this is coming from a guy who sells supplements and who works for different supplement companies to help them develop supplements, and research supplements, and all this jazz. Basically, I'm not a fan of supplements as much as I'm a fan of lifestyle modalities for decreasing blood pressure. I don't know. What would you have to say, Jay?

Jay:  No, totally 100% agree with this. And that's because there's so much low-hanging fruit that is backed scientifically with research and evidence to demonstrate efficacy in reducing blood pressure response. The one thing that I really teach people and want people to learn is how to balance and control their baroreflex mechanism. So, the baroreflex mechanism is the homeostatic mechanism that we have for regulating blood pressure. What's the best way of doing that per research in science? It is what you said, Ben. It is learning appropriate breathwork and using it throughout the day to condition the nervous system, and the baroreflex mechanism to homeostatically control the nervous system. So, it takes work. It takes effort. It's not like you can pop a pill to just easily do that. However, it's something that's innately a part of us that has been proven to help regulate blood pressure.

The other thing that I would mention is what you mentioned with the Zona. That's an isometric grip pressure exercise. Other isometric grip, whether it'd be devices or isometric exercises have been shown to be very effective in reducing blood pressure. Exercise just in general. So, go for the low-hanging fruit of nutrition, exercise, and breathwork, or stress resiliency, or stress adaptation, and you're going to get so much more bang for your buck. Yeah, more time. I wouldn't say more money, but more time that you have to devote to it, but much more longstanding conditioned results.

Ben:  Yup, exactly. So, just goes to show you, you can't pill pop your way out of most situations. It takes a little bit more than that. And supplements are just the extra icing on the cake, which I think could be a perfect place for us to end because we get long in the tooth and we have covered a lot on today's show. But we could, as we usually do, give away some goodies to somebody who's left us a fantastic, nice review on the interwebs. You want to do that, Jay?

Jay:  So, here we go. This one is from albertk2071, who said, “I've been listening to Ben's show for around four years now. Studied this book “Boundless” last summer and I consider it my unofficial masters in biohacking, health and wellness. His incredible work and his outlook on life has helped me to profoundly transform my health and my life. For that, I'm forever grateful.” Thank you, Ben. And thank you, Albert.

Ben:  Thank you for pumping up my day and making my morning. So, yeah. Albert, email [email protected] with your T-shirt size. We'll get a gear packed out to you. And for the rest of you, one of the best ways to support this show and to ensure that I can get kick-butt guests on this show because Jay gets pretty boring is to leave the show a review. And the better our show appears in Apple podcasts, anywhere else, the more likely it is that I'll be able to get the big folks. I know everybody wants me to interview Donald Trump, but how am I going to do it? Unless this show is one of the top health podcasts on iTunes. So, if you want to hear me jam with Donald Trump, go leave us a review. If you don't want to hear that, then just don't leave us a review.

Jay:  The epitome of biohacking is Donald Trump.

Ben:  That's right. And all the shownotes you're going to find–he was sitting in front of me at the last UFC fight, actually.

Jay:  Dude, I saw that. That's hilarious. [01:08:38] _____ some good seats, dude.

Ben:  He wasn't drinking, let me tell you that, but I was. I was drinking whiskey and staring at the back of Donald Trump's toupee.

Jay:  What a day.

Ben:  Yeah. Shownotes are at BenGreenfieldFitness.com/432. Thank you to everybody who's joining us after this podcast comes out, and also joining us live on Clubhouse. Have an amazing, amazing week. And Jay, I'll catch you on the flipside.

Jay:  Sounds good, man. See yah.

Ben:  Well, thanks for listening to today's show. You can grab all the shownotes, the resources, pretty much everything that I mentioned over at BenGreenfieldFitness.com, along with plenty of other goodies from me, including the highly helpful “Ben Recommends” page, which is a list of pretty much everything that I've ever recommended for hormone, sleep, digestion, fat loss, performance, and plenty more. Please, also, know that all the links, all the promo codes, that I mentioned during this and every episode, helped to make this podcast happen and to generate income that enables me to keep bringing you this content every single week. When you listen in, be sure to use the links in the shownotes, use the promo codes that I generate, because that helps to float this thing and keep it coming to you each and every week.
