What kind of diet should you have if trying to get a 6 pack?

Building muscle takes burning calories that you take in. When you work out you are burning away muscle that your body is instantly rebuilding (to be tougher and stronger) doing nothing but dieting won't get you anywhere as a 6 pack is concerned. Boys often eat a ton because we are building muscle which takes energy (which is given off by the burning of calories) eat as much as you want (as long as its HEALTHY chocolate and chips and I'm afraid to say McDonalds won't cut it) but doing it isn't all really hard core you CAN indulge one or twice every couple of weeks as long as you don't let it become 2 or 3 times a week. Doing an ab circuit or weighted sit ups/ crunches should work your upper abs. And a tree trunk (twisting your abs while holding a weighted ball) will work your lower abs. Good luck
