Hm. Let's see...   Misquote a few peer reviewed papers (I have a biochemistry background) to claim some random food is great for weight loss because of random cherrypicked reason from the papers.   Make some A, B, and C random groups of foods or recipes and some arcane way of combining them.   Post nutritional info based on small portions, which fatties won't compute.   Make sure I never say "you can eat as much as you want of this!", instead something like "eat this until satiated" or something similar.   ???   Profit!   Did I get that right? It sounds simple enough :D
