if IF was so great at getting people lean/fatloss, than every single Mr Olympia would be doing it
Eating small meals more often = greater/faster fat loss = game over
Shit.. instead of IF... might as well eat Twinkies and do IIFYM
Nah, comparing the most drugged up of druggies to regular people isn't a fair comp.
And there are plenty of benefits your body gets when it's not digesting food all the time.
If it works for people, who gives a shit? It's easier than being a slave to the clock all day in terms of getting meals in.
Is it absolutely ideal for muscle gain? Likely not, but it might not be a material difference for any natural who trains hard.
