WHAT’S BEING CLAIMED:
- Mark Wahlberg gave a recent update on his rapid weight gain for his role in the film Stu, saying that he had to consume 7,000 calories for two weeks and 11,000 calories for another two weeks.
- But nutritionists warned that overeating can not only cause weight gain, but also “cause long-term changes in the brain that can make it difficult to lose weight and have a healthy relationship with food.”
- Experts also warned against starving yourself or depriving yourself of nutrients to lose the weight gain.
Back in April, Mark Wahlberg talked about his rapid weight gain for his role in the film Stu. He had gained 20 pounds in 3 weeks.
To portray his role, he had to have a fit boxer’s body at the beginning, and then a retired, overweight athlete who was eventually drawn to the priesthood. Because of a tight filming schedule, he had to undergo the changes within weeks.
The actor gave a recent update when he appeared as a guest at Jimmy Fallon’s The Tonight Show.
Wahlberg told Fallon, “Unfortunately, I had to consume, for two weeks, 7,000 calories, and then for another two weeks, 11,000 calories. It was fun for about an hour. It’s such a hard, physical thing to do … even when you’re full, I would wake up after a meal and have another meal. I was eating every three hours.”
They had joked about it on the show, but the actor’s drastic physical transformation may have been dangerous, warned Nicole Avena, a research nutritionist, neuroscientist, and assistant professor of neuroscience at the Icahn School of Medicine at Mount Sinai.
“Overeating highly processed, high-calorie foods can cause long-term changes in the brain that can make it difficult to lose weight and have a healthy relationship with food,” Avena warned. “It can also lead to metabolic disease, heart disease, and other medical complications.”
A 2010 study by researchers in Sweden found that those who doubled their daily intake of calories for a month increased their body weight and fat mass, even after going back to their normal daily consumption.
A 2012 study by the Mount Sinai Medical Center found that short-term “overeating can cause a malfunction in brain insulin signaling, and lead to obesity and diabetes. … [it] impairs the ability of brain insulin to suppress the breakdown of fat in adipose tissue.”
Avena said that overeating frequently “can alter your body’s natural hunger signals and cues. [This] can impact the way your body metabolizes calories and nutrients.”
In The Tonight Show episode, Wahlberg mentioned the difficulty of losing the weight he gained. He remarked, “Losing weight, you just kind of tough it out, you just don’t eat, and exercise.”
“With regard to losing weight, it is never a good idea to just ‘not eat,'” warned Avena. “Not eating can cause your body to go into starvation mode, which can actually make it harder to lose fat.”
The Dietary Guidelines for Americans recommend consuming between 1,600 and 2,400 calories per day for females and between 2,000 and 3,000 calories per day for males.
