I put on fifteen pounds of muscle so that was a lot of eating chicken and a high protein low-carb diet. Also a lot of heavy lifting and a very different kind of training with an ex-navy SEAL guy who wanted to kill me every time I got with him. In a good way.

A boxer's diet should be low in fat and high in proteins and sugar. Therefore you should eat plenty of lean meat milk leafy vegetables and fresh fruit and ice cream for sugar.
