I'll throw this out there also:
Dieting with 'clean' food, as opposed to the same number of calories per day of 'whatever goes/adonis principles' does more than just lose body fat, and help you acheive asthetical goals - you will GAIN discipline, you will GAIN mental and physical benefits from cutting out junk like HFCS and other refined shit!
You will GAIN a lesson on how to say no, which can run into other areas of your life.
