I've seen Pettis hire a guy to cook his meals, and I remember that Carwin also hired a cook. How legit is this for an athlete that is supposed to be professional? Don't they know about food? Don't tell me that Pettis would just sit back and eat Wheaties all day either. I never saw Brock Lesnar hire a food guy. Also, Brock knew what to eat for a guy his size. Are MMA fighters just clueless when it comes to nutrition?
