Welcome 'WhitemanSam'... Lol...

First and foremost, You do have it made since you have that quick metabolism! And as for the foundation on my train of thought... well as long as you basically eat for energy, then the times that you eat for pleasure (and all wrong) is alright. Because you tend not to do it much once you change your way of thinking about food.

Personally, you may be good starting a program like 'Insanity' or weights... Idk... what are your fitness goals? Let me know and tomorrow, I'll share a bit more on what I'm going to try to accomplish.
