I gotta admit I like this Matt Serra guy, seems like a good egg. His website that most college students would use for research, however, includes this gem titled "Matt Serra's Weight Gain":

Controversy arose on MMA websites such as MMA Junkie and Sherdog when Matt's post-retirement behavior resulted in an over-eating disorder. "Terror" instantly gained several pounds, and became a running joke on MMA news sites. He publicly stated his love for high-carb foods such as pizza, pasta, bread, garlic knots, and hot pockets, which is a main contributor to his excessive and uncontrollable weight gain. Some have said that he is in competition with long time training partner Ray Longo on who could be the heavier among the two. It has been noted that Longo's approach are sugar-based carbs rather than just pure starch, including donuts, cookies, cake, and ice cream.
