Geoffrey Woo On The Power Of Ketosis And The Importance Of Fasting

“Look at intermittent fasting as a thoughtful way to understand and be proactive of how you want to consume and eat food.”
— Geoffrey Woo

Greetings, SuperFriends!

Today we are joined by Geoffrey Woo. Geoffrey works closely with researchers at Oxford University and professional athletes to further our understanding of ketosis and human performance. A former computer scientist, he applies a systems engineering mindset to nutrition & performance you don't often see in the space. He's been in Forbes 30 under 30, he has sold Silicon Valley company at age 23, he is author of 2 US Patents, he has published various scientific papers, and much more.

I wanted to have Geoffrey on the show because we've talked about ketosis, fasting, and other things like that, but we've never talked about the extremes. For example, exogenous ketones, what happens in the body during ketosis, or whether you should be going into ketosis if you are just the average human being.

So, I wanted to dive deeper and really get a feel for whether or not this is applicable to real humans. I think I got some really good answers, I certainly learned a lot about ketosis and fasting, and it really doubled down my motivation to fast more, both intermittently and in extended fasts, and to try out some new things.

I really enjoyed this episode, and I'm sure you will as well!

    Great interview with Dr. Greg Wells! He mentioned a doctor from Colorado around the 42:30 point of the podcast, discussing turmeric and black pepper. I couldn’t make out the doctor’s name. Can you provide me with his full name and maybe his website or contact info. Interested in his products.
