Larry The Cable Guy: I'm Too Fat

"The Rock is buff and ripped, so it was funny to see him dressed like the tooth fairy," says Larry, 48. "But it's even funnier to see a fat white guy in a tutu. I didn't care that I was gaining weight. I thought that fatter was funnier."
But as shooting wraps up on the movie, Larry (real name: Dan Whitney) admits that he needs to shed some weight to be healthy.
After losing 50 lbs. last year, he has gained it all back through a poor diet and inactivity. "I was down to 225 lbs.," says the 5'11" funnyman. "Now I weigh about 275 lbs. I've got a lot of work to do."
The fundamentals of weight loss are not a mystery to Larry. "I need to cut out sugar, not eat late at night, and do some cardio," Larry told PEOPLE on the Tooth Fairy 2 set. "I get what needs to be done, but it's hard work."
So hard that he has enlisted the aid of a trainer who will coach him through the process. "A trainer is good," he says, "but it's ultimately up to me to do the work. I always joke that my wife gets me a trainer and I lose 50 lbs. by trying to run away from him. But I know I need to do something drastic."
When Larry gets heavier, he struggles with sleep apnea. "I can't breathe when I'm heavy," he says. "That freaks me out. And everything else takes a lot of effort. Just tying my shoes can make me winded."
Plus, Larry says playing with his kids – Wyatt, 4, and Reagan, 3 – is nearly impossible. They like to wrestle and run. They want to shoot baskets or play baseball. I can't do that as well when I'm heavy."
So what is his ultimate weight loss goal? "I'd like to go down to a B-cup," he quips. "No, I just need to get healthy. I've got a lot going on right now; I want to be healthy enough to enjoy it."
And if there's a Tooth Fairy 3? "I'll get back into the tutu," he says. "But it will just have to be smaller."
