Before anything else, let's get this out in the open first andforemost: The "Fat Loss 4 Idiots" website is genuine and not a scam. It has methods that have worked for a lot of people over the course of its existence.
It is not a self-help weight loss program in the vein of the "The Idiot's Guide To" book series either. It's not a spoof site ridiculing overweight or obese people, in spite of its somewhat questionable, condescending, and grammatically questionable title...
