In 2015, Jimmy Kimmel told Men’s Journal that his weight-loss journey started very traditionally with smoothies and a 2000 calorie diet, which helped him lose 25 pounds. But today, the late-night host’s diet of choice “is starving myself two days a week. People call it the 5:2 diet, but I’ve been doing it since before it had a name. On Monday and Thursday, I eat fewer than 500 calories a day, then I eat like a pig for the other five days.” Kimmel says that his metabolism is revved up by consuming varying levels of calories.
“On fasting days, I’m pretty unpleasant to be around,” he shared. “I mostly just drink coffee and eat pickles endlessly.” If he’s really hungry, Kimmel said he’ll go for a bowl of oatmeal or hard-boiled eggs. And then, Kimmel goes full gluten, pizza, and steaks for the remaining five days. “It sounds hard, but you get used to it and learn you can get through it,” he explained. “It’s helped me stay at 182 pounds. And it’s made me appreciate the food that I do eat.”
Now exercise is another story. “I’ve realized that you can work out, and that’s great, but if you really want to lose weight, you have to eat less,” Kimmel told the publication. “I always thought, ‘Well, if I start running, I’ll be in good shape.’ But I know people who run every day, and they still have a gut.”
