The bulk of your diet will consist of clean food that's full of vitamins, minerals and has a high satiety index because your muscles need a high amount of high quality nutrition to grow.
In addition, clean food will speed up your metabolism and improve your natural hormonal balance - both which are extremely important for the skinny-fat guy with a naturally slow metabolism and low testosterone production.
With that said, I will allow you to have 1 or 2 cheat meals per week where you can go all out and have anything you like. (Whether you can have 1 or 2 is something I will decide when I make an assessment of you).
The cheat meals will allow you to enjoy the foods you miss and thereby prevent binge eating over the long-term.
