In this recent interview, current UFC heavyweight champ Brock Lesner, speaks to GNC about his horrendous bout with diverticulitis last year, as well as his amazing comeback with a win over Shane Carwin.

“It was a comeback fight for me. I was in the hospital, I was out for a year,” Lesnar said of his bout with Carwin. “I had to readjust my diet, get more fiber in the system to kind of clean things up a little bit. The fight itself, it kind of climaxed to a point where–I got my butt beat down in the first period and I had to make a comeback to win; that was my story for the whole year.”
