 I think we have an innate ability to know what's healthy for us and what's not, even though we trick ourselves sometimes. So I'd say first of all, that first bit is that you have to starve yourself to be thin. You don't. And if you do, you'll stress out and you'll probably end up bigger and bigger and bigger as your adrenals don't cope and you'll produce more stress hormones, which makes it harder to control as fat. And you'll store more fat, as your body thinks. You're in a stressed fight of light state ready for whatever. So that's my first one. You don't have to starve yourself. Secondly, I would avoid anything that is cult-like in its advice. Do you know what I mean? So that you have to do this. You have to follow a particular diet for your whole life in order to succeed. It's about healthy eating, not about dieting.
