Mark Wahlberg is back in the gym after gaining 20lbs for a role.
The actor put on 20lbs in six weeks so that he could play a boxer in forthcoming movie Father Stu. But 50-year-old Mark is now back in the gym, and he seems to have slimmed down considerably.
He was seen in F45 Training Hollywood in LA, working out with Mario Lopez - aka AC Slater from Saved By The Bell.
He could be seen on the weights and doing pull-ups, still sporting his short hair, having had to shave his head for the film.
Previously, Mark spoke to Jimmy Kimmel, saying he planed to eat 'lots of burgers and lots of buns' in order to gain the weight.
He also said at the time that he planned his first meal to be a '20-piece chicken nugget and 20-piece hot wings from Kentucky Fried Chicken with a six-pack of beer'.
The actor joked: "Why not start with a bang?
"I might need a porta-potty too, but you know what, I'm ready to go."
He has since shared photos of himself after he gained the weight. Although he said he wanted to eat junk - who wouldn't? - he was actually on a strict regime.
He had a calorie goal of 7,000 per day, with his personal chef Lawrence Duran telling E!: "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.
"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."
That's a pretty hefty diet.
