Listener Q&A:

As compiled, deciphered, edited and sometimes read by Rachel Browne, the NEW Podcast Sidekick.

How To Get Beautiful Skin

Sonia says: She recently started eating a lot more eggs and her eczema flared up. Her Naturopath advised her to start supplementing with Evening Primrose Oil, as she said there was excellent research to suggest efficacy of Evening Primrose Oil and eczema or skin conditions in general. Sonia was apprehensive because of the Omega 6 content. What are your thoughts?

The 5 Worst Exercises

Tyler says: He recently watched a video from Jeff Cavilliar where he outlined the 5 Worst Exercises. He said these were chest flys, behind the neck shoulder presses, upright rows, good mornings and leg extensions. What are your thoughts on this? If you don't agree, what do you think the five worst exercises are?

    Assuming the Cyrex test is still the gold standard for allergy testing, what is the best way to find a doctor who administers this test? Cyrex does not offer a listing of practitioners on their website.

    1. In terms of doctors, here are a few directories that may help you find a good functional medicine or naturopathic practitioner in your area:

      • HealthProfs.com
      • FunctionalMedicine.org
      • Naturopathic.org
      • PrimalDocs.com
      • PaleoPhysiciansNetwork.com

      That will ensure you find someone who I would likely vouch for!

    Hi! Just wanted to chime in on the subject of excessive snacking in Europe. I live in a small country right next to France and my region has a lot of cultural references in common with the country of Brie and baguette.

    Where I live, as well as in France, children are usually allowed a small snack at a specific time during the day. The most common one is taken in the afternoon around 4 PM, this particular snack is referred to as the "goûter". Depending on where you come from, it consists in either a small pastry or cookies, a piece of bread with chocolate, a tartine, fresh fruit, compote, cheese, or yogurt, and is washed down with either hot chocolate, tea, fruit juice or a glass of milk. In some less frequent instances, you might see young kids having an additional mid-morning snack, but it's usually during school days when they get up earlier, and not during holidays or weekends. Growing up, some people keep the habit of snacking on something sweet in the late afternoon, some replace it with an apéritif, others lose it and adopt a 3-square-meals-a-day model. It's a matter of individual and regional preferences.

    However, I can confirm that in general, uncontrolled snacking / grazing, AKA "grignotage" is pretty much frowned upon and considered a dietary sin. In fact, there are a bunch of PSAs for better dietary practices floating around in the media, and part of their advice is to avoid grazing throughout the day. And yes, as a kid, you're usually not allowed to go randomly in the kitchen, unless you're coming to actually help with the preparation of a meal, or you have a particularly generous grandma baking something nice in the kitchen. :)

    Thank you so much for this podcast! It really interested me as I suffer from skin conditions as well (acne) and have been struggling to find solutions. I have heard a lot about Vitamin A, as you mentioned, and how it can be a miracle worker for acne. However, as it is a fat-soluble vitamin, I am worried about taking too much and damaging my liver. At the moment, I am simply increasing my uptake of Vitamin A rich foods (such as butternut squash, pumpkin, sweet potatoes, etc.) (I am vegan as well…(ya Rachel!) so no animal products for me) to see if that helps but am wondering about your thoughts towards a supplement. I cannot seem to find a straight answer on whether it is safe or is not to supplement and how to do so. Thanks!

    1. You MUST MUST MUST take Vitamin D and Vitamin K2 if you are taking Vitamin A. You can use the EXOS multivitamin for this <a href="http:// (https://bengreenfieldfitness.com/multi),” target=”_blank”> <a href="http://(https://bengreenfieldfitness.com/multi),” target=”_blank”>(https://bengreenfieldfitness.com/multi), or you can just get plenty of mushrooms (they store D), sunshine, and natto (for the K2) along with Vitamin A Rich foods.

    Love the podcast. You’re doing great Rachel… Maybe we should send all the haters season one of Neigbours and Home and Away – that’ll keep ’em busy for awhile :)

  5. Jim says:

    Hey Ben,

    I stopped using the “smith bar” (I think that is what you called it) helper for squats (I hope you are proud), but is it ok to use it for three-way calf raises on a platform, which can be difficult to balance? Also, what are some alternates to the Ab/Adductor machine? I have some issues with my hips and want to keep those groups strong.

    Side Note: I accidentally sent this as a question. Please, disregard.

    Thanks, as always,

    I love that you've got a vegan, yogi chick with a cool accent as your co-host! Makes it more welcoming for the rest of us chicks who aren't into such extreme, barbed wire crossing sports to relate to all of the amazing knowledge and information you have Ben. I found your site recently, after watching a CreativeLive replay of your course. I think Rachel is doing a great job as co-host, I really enjoyed this podcast. I really, really appreciate the time and effort you put into the information you share with us. I'm all for more interesting accents on the show too :)

    You could use something other than 'mate'. Bonaza, shoot through, sheila would all be good.

    Or you could get a kelpie; you'll never look back.

  8. IwarW says:

    Hey, what brand of emu oil do you use?

    1. I have giant "vat' of it that my dad gave me. Literally a vat. He bought it from a local emu farmer. But I don't know the name of the farm. Sorry I can't be more helpful! If it does help, I am designing a skin serum that I will launch soon, so stay tuned!

  9. davidbremers says:

    Hey Rachael and Ben, (I'm an aussie so Rachael goes first!) thanks for the podcast, you are the best fitness and lifestyle podcast on the net.

    Don't worry about the haters Rachael, as they say in Compton, "Haters gonna hate". You are a great balancer to Ben and I haven't noticed any awkward bits, it all seems to flow well. You'll get to know each other's style just like any partnership.

    Alright, now I'm off to hunt down some emus for a workout and some oil for my nursing wife. :D

    Hey Ben-

    In regards to your comments on Evening Primrose oil and GLA, it is my understanding that, although GLA is an Omega-6, due to the location of it’s double bonds that when it is oxidized it typically produces anti-inflammatory eicosanoids. This is why it is often included in EPA/DHA supplements to enhance the effects by producing more varied anti-inflammatory eicosanoids when the LCFA are metabolized/oxidized. Any thoughts on this? Love the Show!!

    1. This is true but you still risk Omega 6 excess IF you are overdoing seeds, nuts, commercial meats, etc. So it all "depends" on your dietary intake too.

  11. IwarW says:

    Hi Ben, what brand of emu oil do you use? I was searching through iHerb (as I'm not in the US) and found two interesting ones, 1.Kalaya Calandri, Emu Essentials and 2.Thunder Ridge Emu Products, Emu oil. I'm interested in experimenting with my inner thigh stretchmarks caused by mass gain (squatting, duh). Big thanks!

    Hey Ben…that Onnit link in the Special Announcements up there doesn't work.

    Hi Ben
    In the podcast i understood that an elite cyclist improved his VO2Max and time trialing by double digit percentages and that a study showed that by substituting 50% of running training for cycling there was a negligible decrease in performance. Also that restrictive breathe swimming training improves efficiency and economy in running.
    At the end of the podcast you summed up by saying '….ultimately what most of the research is showing is that cycling will make you a better runner, than running will make you a better cyclist…….and swimming with restrictive breathe training has a complimentary effect on cycling……'
    The studies and n=1 that you quoted say the opposite of your summary, are they contradictory to the bulk of research/evidence coming out or did i miss something?

    1. Sounds like you misunderstood what I said. I said the cyclist INCREASED his performance by substituting some running for cycling, and then cited a bunch of research on cycling crosstraining for running. So no, not contradictory!

      1. matt_in_paris says:

        Hi Ben
        Thanks for your response. Unfortunately I am still confused. I understood that you said that the elite cyclist (significantly) increased his performance by substituting some cycling training for running. Then at the end of the podcast you summed up and said that '…. ….ultimately what most of the research is showing is that cycling will make you a better runner, than running will make you a better cyclist'. This appears to be a direct contradiction to me as you said during the podcast that the 3000m runners substituting some cycling for running training showed a tiny decrease in performance.
        Also you stated in the podcast that restrictive breathe swimming training 'improves efficiency and economy in RUNNING', while in your summary at the end you said restrictive breathe swimming training has a 'complimentary effect on CYCLING.
        Sorry to be a pain in the rear.
        Matt (in Paris France, not Texas!)
