Yea, counter-point: IF makes me more anxious and irritable, and no way it makes me stronger as someone who lifts regularly (5x week)...

IIRC some studies I’ve read say that IF increases cortisol levels which would explain the anxiety and which I believe is bad for muscle-building.

I haven't replaced exercise with fasting, I think you still need both! Of course you wouldn't be as strong as someone who lifts 5 times/week if you didn't. I'm speaking of strength relative to body weight here... I see no benefit in being able to bench press 200kg, I rather do 15-30 chins with no effort. Sleep, exercise, a good diet and relationships are all required for good long-term benefits in any endevour.
