Listener Q&A

As compiled, deciphered, edited and sometimes read by Brock Armstrong, the Podcast Sidekick.

How To Maintain Focus During Long Workouts [44:30]

Tom says: “I'm preparing for an ultramarathon (264 miles) in Wales this May. I will most likely do it without a support crew. There will be sleep stations at miles 80, 140, and 200 and I plan to take advantage of these. What tips do you have to prepare myself for the inevitable cognitive decline that accompanies events of this nature?”

In my response, I recommend:
Amino acids to stave off central nervous system fatigue
No-doz caffeine + L-theanine + TianChi + nicotine (what I did during the Kokoro event you can read about here)
My “How To Get Into Ketosis” podcast
Kion Aminos

Does Cholesterol Go Up On A Ketogenic Diet (& Is That Bad?) [56:55]

Glenn says: I'm a 60-year-old man. I went to a paleo diet about 5 years ago. I recently tried the keto diet and everything seems off. My cholesterol and LDL skyrocketed. My triglycerides are low, my blood sugar is low, my CRP is low. So was I better off on paleo?

    Hey Ben! Awesome podcast and I’m so glad that you’re gonna have Dr. Kaufmann on! Right after your podcast with Dr. Andrews I grabbed Doc Kaufmann’s book and swallowed it in a couple of days and my first thought was: “she should come on Ben’s podcast”.

    I’ve reviewed her recommended links for the supplements that she’s researched and some of them contained not-so-great additives like magnesium stearate. I’m putting together a super clean supplement stack with her recommended dosages for myself and I’d like you to discuss the effect of additives (such as decreased bioavailability) and the importance of timing when supplementing, if possible! Thanks!

    Hi ben,
    I was wondering what experience you have with actually regenerating connective tissue like ligament, tendon, and fascia. I know about injecting stem cells into tissue but i wanted to know what experience you have doing that solely through diet. I am doing research about colostrum, and am thinking about taking it throughout the day indefinitely. Raw colostrum that is. I would appreciate your feedback

    Dr. David Sinclair was on Rogan recently and mentioned that taking amino acids was a bad idea overall….essentially a tradeoff b/t short-term performance and overall health & longevity based on studies. Any thoughts? Thanks.
