I like IF a lot too, but when I'm in a heavily active phase of my life--say lifting 3x week, climbing 1x, jiujitsu 3x, and full on dance rehearsals 3x a week--I find I start to crumble unless I eat more to keep fueled.

I should get back to lifting (I'm just lazy), and it's possible that some of the other purported IF effects would kick in if I did so --- but the literature isn't encouraging, at least what I've read (I may be reading the wrong stuff!).
I should add: I'm in pretty terrible shape! I joked on Twitter about how, in the post-AHCA US, my wife Erin will have trouble getting insurance despite her constant exercise and diet regime, while I, subsisting on pork fat, nicotine, and whiskey, will have no trouble. I mean, I eat a green bean here and there, but for the most part I'm not joking. :)
I don't have a lot of health objectives with IF; it's just mostly painless and imposes some structure over what I eat and when I have to take time out of my day to eat.
For major events, I'll eat differently. But for general training, I am fine fasting until lunch.
