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?
The leptin 'rules' are meant to reset sensitivity, as mentioned above. As someone who is leptin sensitive, I still follow the 'rules' for the most part and it really works well. I also include some IF as well as fasted workouts however.
Eating soon after rising may not sound appealing but your body will adapt within a week or so and you may find it works for you. My ideal meal pattern is a big protein and fat breakfast around 8 and another big meal around 3, without needing any snacks. This gives me a 17hr fast without feeling like I'm putting much stress on my body, and is quite easy to do (and convenient).
