Mark Wahlberg has revealed that he had to consume 11,000 calories a day during the weight gain process required for a movie role - and regretted it.
The 50-year-old (yes, really) appeared on The Tonight Show Starring Jimmy Fallon to promote his new film, Father Stu.
Speaking to host Jimmy, he said: "Unfortunately, I had to consume, for two weeks, 7,000 calories, and then for another two weeks, 11,000 calories. And it was fun for about an hour.
"It's such a hard, physical thing to do. Losing weight, you just kind of tough it out - you just don't eat, and exercise.
"And this, even when you're full, I would wake up after a meal and have another meal.
"I was eating every three hours. It was not fun."
When he was asked whether it's harder to gain and lose weight the older you get, the star replied: "Yeah, absolutely."
He continued: "Once the metabolism starts to slow down it gets really difficult.
"But, you know, it was something... I'd been trying to get this movie made for six years, we only had 30 days to shoot it. So I wanted to really make it happen."
Earlier this month, Mark's personal chef spoke to E! about the actor's weight gain diet, saying: "His first breakfast is four eggs - that's the pre-breakfast.
"Then, he does his workout and then after the workout, which is usually around 5 to 6 o'clock in the morning, we do eight eggs, six strips of bacon, a cup of rice, two tablespoons of olive oil and a protein shake.
"It's his protein-inspired mass weight-gainer to help build on a little more muscle as well."
the chef added: "Then, three hours later, we do some kind of ground beef or ground turkey, whether it's been made into a hamburger patty or a meatloaf, with another cup of rice.
"And then, three hours later, I usually do half of a roasted chicken, another cup of rice.
"I'll do about a cup of cooked spinach and a cup of cooked beets as well.
"After two, essentially, main courses, Mark ate an eight-ounce veal or pork chop and a four-ounce piece of salmon with rice and beets, before his last big meal consisting of eight ounces of some type of steak, eight ounces of some kind of white fish, like a sea bass or a halibut, and load up on tons of vegetables."
