I’ve been doing it for years too. Works fine on gear. The only compound I’ve taken where I had to drop it was superdrol, because it made me go kind of hypo. I just drank a half gallon of fairlife chocolate milk and that took care of me until my usual eating window. I experienced this to a lesser extent on tren, and I’d have to have candy bar or something. It’s not like the world ends, or anything of note, really–happens if you break your arbitrary window.
I don’t care whether or not it’s ideal at this point, as a former fatty who loves to eat it helps me keep me in control of my diet whether I’m cutting, bulking or maintaining. I find it especially helpful with the latter two—when people are like “how could you bulk on IF?” I’m like, um “I like food.”
I find the leangains macro protocols to be too much for me to follow, but the 16/8 window and Martin’s approach to training have done me a lot of good.
I don’t, however, think it’s for everybody. I think it’s ideal for people who hear “skip breakfast, have a light lunch and a huge dinner” and think “oh shit, that sounds amazing!” Compliance>Anything else. I’m past the point of caring about what its benefits or drawbacks are. Greg Doucette, whose videos on gear I like, just put out a “IF is terrible!” video and I’m like “whatever, maybe he’s right. It does the job fine for me. If I eat six small meals a day, or don’t have a giant man meal at 7 I’m not gonna be happy and I’m gonna fall of the wagon sooner or later.”
