Time between meals is the strongest and most sustainable lifestyle choice to lose weight and keep it off. 18-24 hours between meals day in day out as an adult. You will asymptotically approach a natural weight by eating what you wish if you follow the timing rule.
Time between meals could actually be a factor in my success so far. I only eat 2 meals per day most days. I've done IF and OMAD before, but kind of "Ad lib in the window" which still made me gain weight typically.
It could be that I'm minimizing insulin by only eating protein in one meal, and my other meal is energy-dense (heavy cream) but doesn't raise insulin at all. So in terms of insulin, it's an OMAD diet yet still allows me to eat to satiety.
