Interesting. This goes against the philosophy of [working to failure + enough recovery] that I’ve been following so far. I’ll have to do some more research here.
You've got to be kidding me. Fasting for two days + frequent strength workouts sounds like a 100% guaranteed recipe for catastrophically low blood sugar levels. I get hangry and stupid if I don't eat for a few hours.
To achieve hypertrophy and strength what is needed at minimum is a sensible program combined with over-time calorie surplus. 48 hour fasting is not gonna suddenly change all that.
If anything fasting increases growth hormones. In my experience it actually improves my performance (probably due to HGH increase and autophagy). Educate yourself on it instead of going by what "sounds like" or following conventional wisdom (such as "working to failure").
Lean mass % increased by 2.2% with fasting and only
0.5% with CRaP. In other words, fasting is 4 times
better at preserving lean mass. So much of that old
‘fasting burns the muscle’.
