If one were to do extended Zone 2 exercise (e.g. 2-3 hrs on the bike) early in a fast, would this shorten the time before the body goes into ketosis? If one assumes that extended time in ketosis during a fast is beneficial, is it reasonable to think that this kind of exercise at the beginning of a fast could amplify the benefits of a mult-day fast?
Manolis Kellis, of the computational biology department at MIT, was recently on Lex Fridman's podcast. His team's work on using automation and data analysis techniques to gain insight on disease is interesting. While Lex's podcast was great, I expect your approach to the work would lead to a very different and useful conversation.
I'm 6'0" and my weight has varied between 142-152 lbs my adult life (now mid 30s). For health reasons I'd like to add about 15-20 lbs of muscle, and to do it quickly, safely, and without gaining a bunch of extra fat. What's the recommended way to do this?
