Lewis is doing the 30-day weight-loss challenge for UFC Personal Trainer:
"I have a confession to make. I fit into the media stereotype of a gamer quite well; beardy, long-haired and overweight. I also lack in confidence partly due to my body image and while I am all too happy spilling words out on to the Internet, I often fail in social situations. This is all going to change.
I think UFC wants to kill me."
