You may remember Christopher Kelly and "". In today's episode, Chris is back, along with special guest Dr. Tommy Wood. The reason I've invited Chris back on the podcast is because he recently wrote me about new methods he's been using to identify how to increase EPO, increase oxygen consumption, beat anemia, boost red blood cells, and get double-digit percentage increases in power and endurance. I'm always looking for insider tips on how to maximize my own athletic performance, so figured it would be a good idea to have Chris on to talk about these new, little-known testing and treatment methods. Christopher Kelly is a computer scientist, pro mountain biker, certified Functional Diagnostic Nutrition Practitioner and graduate of the Kalish Institute. Chris is British but lives in California where he runs the functional medicine practice . Chris has been on the podcast twice before, once to talk about salivary hormone testing for adrenal fatigue, and once to talk about organic acid testing. My other guest, Dr. Tommy Wood is a qualified medical doctor, graduating from Oxford University in 2011. He has a previous Bachelor's degree in Natural Sciences and Biochemistry from Cambridge University. After working as a junior doctor in the UK for two years, Dr Wood is now working towards a Ph.D. in neonatal brain metabolism at the University of Oslo, Norway. During our discussion, you'll discover: -Why oxygen deliverability is so extremely crucial if you plan to compete at elevation or altitude, or you want to maximize your physical performance... -The exact blood-building protocol Chris used to get a a 32-watt (9%) improvement in his cycling power at threshold... -Specific conditions you probably get exposed to that directly shut down your ability to produce red blood cells and EPO and what you can do about it... -How to know if you're deficient in any of the nutrients required to produce red blood cells... -The common nutrient deficiencies (which Chris had) that severely hamper your oxygen delivery capabilities, and how to fix them... -The best way to track and monitor whether excessive red blood cell destruction is occurring... -Little known ways that you can actually lose red blood cells, and how to test to see if that is happening... -And much more!
