I've tried various IF protocols, particularly a four hour feeding window, and have mostly struggled with it. I've just gotten hungry early or late, and after a few weeks succumbed. Or I find myself going to bed way early to evade my hunger. IF hasn't been impossible for me, but difficult.

And then suddenly, it's easy, natural. Now I eat just once or twice a day without intending to. It would be an effort to eat more. The difference for me is a carnivore diet, mostly beef. It's just far more satiating than anything else I've tried and I've done most things from raw veganism to this.

I do believe that when I eat matters, but what I eat makes a big difference to when.
