- Holy cow. Check out what WiFi can do to you. Scary.
- This is interesting: if you push your nervous system just *slighty* too far you can “overcompensate” & bounce back even better.

Listener Q&A:
As compiled, edited and sometimes read by Brock, the Ben Greenfield Fitness Podcast “sidekick”.
Casey @ 00:27:35
He had an idea to combine cold thermogenesis with the Litvinov Training Protocol. He wants to substitute a 400m swim in icy water for the run. Are there any health issues involved? Will his heart explode in the middle of the swim?
Ribose @ 00:35:41
He is taking D-Ribose from Now Products and is wondering about dosage (the website says to take 1.5 level teaspoon prior to exercise and more if you are a serious athlete). How does he know how much to take and if he takes too much, what might happen?
~ In my response, I mention www.X2Performance.com and the code GREENFIELD $10 off every case.
Eric @ 00:41:37
Has been watching the Superhuman Conference on DVD and is wondering what the scale is that Ray Cronise mentions during his talk. It measures RMR and might be called the Y-Rain scale? What is it and how does it work?
~ In my response, I mention the Withings scale and the Superhuman DVD's for $27.
Michael @ 00:45:47
He is a combat rescue helicopter pilot and has a herniated disc. He is being treated with ART, Dry Needling and decompression/manipulation. He is doing a 100miler in September and IM Florida in November and is wondering what he can do on his own to get through it. Pain's not bad – he is still able to run, bike and lift. It hurts most when he sits for long periods of time.
~ In my response, I recommend Michael listen to episode 224 for compression belt information and also to episode 235 for nerve pain tips where in my recommendation for pain management to JD, I recommend: A whole food antioxidant that includes vitamin B, D, E and wild plant derivatives, such as LifeShotz. High omega 3 fatty acids and GLA intake, including borage oil, Natural painkillers from something like phenocane, High magnesium intake, A zinc supplement, and Glutathione. I also recommend episode 138 on how to stop chronic pain. I mention Lifeworks Wellness Center and also regenadisc and stem cell therapy: www.recytecorp.com and www.swisscelergen.com. And lastly, neurolinguistic programming with Andy Murphy.
Steph @ 00:58:44
She is wondering if there are any concerns around nutrition or exertion while training for a marathon with epilepsy.
John @ 01:03:08
Would like you to explain Garmin's “Training Effect”, if you can. He gets very strange and confusing readings. Also, he would like to know if a score of 60 is really bad from the SweetBeat HRV app? Does it really depend on the individual or should he be working on getting it higher?
~ In my response, I recommend listening to this heart rate variability interview.
At the end of this podcast, we play 5 year old Terran Greenfield's song from “The Clownies”, which you can grab here for $1.99.

I just watched your keto kale smoothie. I have been using spinach (tons) in my shake every morning for almost 2 years and haven't had any negative effects. I am now concerned about oxalic acid, but also concerned about taking calcium supps. Can't excess calcium be a problem? I also do a green juice a few times a week that has kale in it so that would mean I am adding calcium twice a day. Not sure what's worse, the oxalic acid or excess calcium? Thoughts?
I'm a fan of about 400-800mg per day of calcium assuming you get adequate Vitamin D, Vitamin K and magnesium. Here's some more research for you:
Bolland Mark J, Avenell Alison, Baron John A, Grey Andrew, MacLennan Graeme S, Gamble Greg D, Reid Ian R. Effect of calcium supplements on risk of myocardial infarction and cardiovascular events: meta-analysis. BMJ 2010;341:c3691
Bolland Mark J, Grey Andrew, Avenell Alison, Gamble Greg D, Reid Ian R. Calcium supplements with or without vitamin D and risk of cardiovascular events: reanalysis of the Women’s Health Initiative limited access dataset and meta-analysis. BMJ 2011;342:d2040.
Calcium from kale: Heaney RP, Weaver CM. Calcium absorption from kale. Am J Clin Nutr 1990; 51:656-657
OK, so D-Ribose is produced naturally by the body, and now you're adding exogenous D-Ribose. Isn't that usually a bad idea over the long haul? (Just thinking of discussions about exogenous testosterone suppressing natural production.)
No, because nutrients do not operate on a negative feedback loop like hormones do.
I have been supplementing with it for years per my ND. I was always taking it prior to workouts, but read something on Kruse's blog about taking it after. What do you think is most beneficial?
I've tried both and I think that as long as you're "loading" with it, it may not be too important. Main reason I'd take it before is that what I'll be doing before Ironman.
on the wifi issue, I'm disappointed that you've latched onto this one single "experiment" as anything even remotely conclusive. if they performed the experiment with a hundred different samples in a hundred different conditions controlling only for wifi exposure it MIGHT demonstrate something. as it stands it's the same as the experiment where some kids tried to show a difference between watering plants with microwaved water and unmicrowaved water. the test was so small the results mean absolutely nothing.
there is no known mechanical explanation for why the ridiculously low level of radio power output from a wifi router would interfere with plant growth. I have several plants here in my home office with my wifi router. my wifi is on 24/7. my plants do just fine. I even know of people who use their wifi router as a heat source for seed germination without issue.
You should read the book "Zapped" by Anne Louise Gittleman.
Ben, Iove ya like a brother, and love your podcast, but I'm with APC on this one. You are way off base for standing up for this "study." When you trash some other studies, you use your in depth knowledge of the field, point out flaws, note test inconsistencies, and research other counter research. That's what you do when you disagree with something.
But in this case, because you seem to want to believe (right or wrong, that's not the point) that cell phones are bad for you as side note, you latch onto this as some sort of proof. This was not a real study. It was done by school children. There was no humidity control. No temperature control (both of which the HEAT from the wifi router would make worse for the plants).
Then you yourself acknowledge that you don't know a darn thing about frequency!!! Wifi is at 2.4GHz, which is the same freq band that microwaves work at. That band is absorbed by water, which is why microwaves (relatively) efficiently heat up your food via the fluid in it. Works great at 2.4GHz. Works totally SUCKY at 900MHz, or 800MHz, etc. Other than 4G, cell phones work in bands that do NOT heat up water molecules nearly as efficiently, but while you don't have the technical knowledge to know that, you still make the leap that a 2.4GHz wifi router has the same effect that an 850/1900 GSM band phone does.
I guess the point I'm trying to make, and I hope you take it constructively, is that your relatively blind acceptance of this kids science project on the level of soaking colored water into celery sticks contrasts dramatically with your in depth refuting of other studies that are far, far more likely to be true.
And really, I love your stuff, but APC was right: you're off base on this one, regardless of whether or not cell phones are bad for you.
I understand this was not a flawless study but I would DARE you to turn of WiFi and wireless for a few days in your house and see how you feel. I did it and the reduction in brain fog and "edginess" were amazing. You should also read the book "Zapped" by Anne Louise Gittleman. Sorry for brevity but I am about to hop on a plane. Just want to emphasize I'm not taking this study as "stand alone" proof of something I've seen affect people over and over again.
Hi Ben. Thanks for the info today on HR Variability. Per your comment however, my variability did go up and down but, it never went any higher than 64 (even before Sweet beats upgrade). Should I be looking into this? My doctor doesn't even understand it. :(
Any suggestions are appreciated.

Have you had cortisol measured? Any other hormones? We'd have to dig a bit. You can get a consult at http://pacificfit.net/items/one-on-one-consultati…
