Four months ago, Caldon Grimes said he wore pants with a 44in waist.But yesterday, the winner of the 2011 100-Day Challenge said he now wears a 36in waist and needs a belt to keep them up.Over 100 days of diet and exercise, Mr Grimes was able to lose 68lbs, around a quarter of his body weight.“I feel great,” he said yesterday. “I’m not tired anymore. I haven’t weighed myself since the competition, and I’ve been sticking to the diet, so I might have lost a little more since then.“I didn’t get into this for the celebrity thing, I wanted to push myself as far as I could go.”Despite the challenges of the boot camps and a rigorous training schedule, Mr Grimes said the most difficult part was the start of training.“The first two weeks were the worst part. Not eating the same food that my wife was having was difficult to get used to,” he said. “Now, I’m used to it. My favourite snack used to be M&M’s, but now they don’t even phase me.“The exercise part of it started out hard and as we got used to that hardness, they made it harder.”Theresa Brangman was named the women’s winner, losing 65lbs, 23 percent of her body weight.“I feel great,” she said yesterday. “I feel good, it feels excellent.“I’m still exercising and I’m still on the diet. This is a lifetime change.“People come up to me and say that I’m the best, that they could never do something like this, but I tell them that it’s a good experience.”Andrew Phillips, co-organiser of the programme, said this season has been the most dramatic yet, with a number of strong personalities and the most difficult challenges yet.“It was exciting. I think it’s the most emotional one we have done by far. The drama was really running high this year,” he said.“The Regiment boot camp really took the show to another level. Bermuda has not seen anything quite like that.“They were shooting guns, running up Kilimanjaro. They basically did everything you go through in boot camp and then some.”While he said he is pleased by the show’s popularity, he is excited that the programme is making a difference to people, encouraging healthy lifestyles at a time when obesity is a national problem.“I think we all know we have a biblical amount of big people on the Island,” he said.“In terms of getting the message out there, it’s working, and that’s what we like to see. There are so many negative things on television that people can mimic, and I think getting fit is a positive one.“We like to encourage people to keep the weight off, but not everybody does. I like to think that most of the people keep most of the weight off.With the show’s fourth season coming to an end tonight, Mr Phillips said they are already planning next year to be even bigger in scale and would-be contestants have already begun to line up.“This season still hasn’t finished yet, but we have had numerous requests already for next year.”
