UFC Fighters are some of the strongest, most athletic and highly tuned athletes in the world. You already know that they work out and train very hard, but what exactly do they eat?

Andrei Arlovski: “I take Gamma O 2x a day and I try to only eat chicken, fish, fruits and vegetables.”

Randy Couture: “The green drink has been a phenomenal addition to my diet and training plan.”

Sean Salmon: “You know, I wasn?t getting as many calories as I needed, which in turn was affecting my training. This time around, I started training real hard, you know, two a day and three a day workouts at twelve weeks out but I didn?t do a thing with my diet until four weeks out and that kind of enabled me to give me those extra calories, extra sugar, extra fat to really keep my training intensity real high and my motivation real high. So, I think this has been my best, most productive training camp ever and I think that?s one of the reasons why.”

Elvis Sinosic: “No specific diet. I try and stay away from carbohydrates after 6pm. I try to eat smaller meals (to keep my metabolism up). I tend to eat lots of chicken, rice, and pastas in the lead up to a fight.”

Mac Danzig: “It wasn?t until I was 20 and I got a job working at an animal sanctuary in Pennsylvania called Ooh-Mah-Nee Farm that I was able to meet people who were vegan and realize how strongly some people felt about it and how many healthy alternatives to animal products there were. I experimented with a vegan diet for about a year, but once I started training full-time for fighting, I believed what certain people said and started eating chicken again because I thought that I had to have some kind of animal protein in order to be a successful athlete. It was crazy because my diet was still pretty much vegan, except for chicken about three times a week. It never sat right with me. ? I would still go through spells where I just couldn?t eat it, and about 2 years ago, I read a Mike Mahler article on an animal rights Web site where he explained his vegan diet for training in detail, and I said, ?That?s it?I can do it too,? and I started 100 percent vegan again for life and I?ve never looked back. I feel great.”
