Been fasting everyday for 20-24 hours since June 1. Once you get used to it theres nothing to it. I like that I can feast everyday and on top of that its much easier to eat healthy and make a good decision about the foods for your feast. The benefits to my focus while fasting is significant. There are streaks almost daily where I feel like I am on adderall just pumped with adrenaline. Also, you get a muscle pump during a fast. I don't know, not for everyone, but it works for me.
It sounds like he's doing Intermittent Fasting (IF), where you only eat for specific periods each day-- the precise amounts vary, from 16 hours fasting / 8 hours eating (basically 2 big meals) to 20/4 "Warrior Diet" (1 huge meal).
Do you workout in fasted state (before the feast)? If yes, how well does that go? Martin from leangains recommends taking large quanitites of BCAA before fasted workouts, but I don't want to live off isolated proteins.
I usually work out in a fasted state. I dont really mess around with supplements. Full Disclosure: I was fat, and now I am skinny. My bf is at 14%, so I am not ripped like hollywood, but I have made some good gains with this protocol and also feel better than ever. I am not a bodybuilder, just a dude trying to be relatively fit.
I eat all my food in a 4 hour window, 6-10 at night. Usually I workout from 3-4. I like lean gains, but I mainly follow the Warrior Diet put out by Ori Hoffmekler. He is waaaay ahead of his time.
In my opinion there is no 'right' diet for everyone, but definitely worth trying different things to see what works for you.
