I keep hearing the hype surrounding Leptin. Can someone please explain its role in the body and weight loss? Are there any recommendations how to manage its levels apart from "eat healthy and exercise"? Is it just another trendy topic in weight loss industry? I understand that is acts as appetite suppressant. the thing is - ever since I was a kid I always felt hugry and could eat a lot without feeling full. To be honest sometimes when I eat at buffet at maximum capacity- I start craving sweets and ice cream when I come back home..... BADLY.
