According to much of the advice I've read surrounding leptin, the leangains approach is not very healthy. Skipping breakfast, eating at night, etc. I've tried each of them and leangains works much better for me. I'm just not very hungry in the morning and I like eating a large lunch and dinner (I've been eating two meals a day so that's not exactly leangains, I know). I've been skipping breakfast for about two weeks and have lost 7lbs without any calorie counting and a couple minor cheats. I'm not all that active right now, I sleep very well, no alarm clock, etc.
So what's going on here? Sorry for the vagueness. Why is leangains healthy and effective given that it violates some of the leptin rules?
