Colin Farrell gained 40 pounds in two months for the film The Lobster on a nauseating high-carb diet.
Farrell binge-ate pints of microwaved ice cream, pizza and cheeseburgers to pack on the pounds in 8 weeks, as Celebrity Health Fitness has reported.
“I would put [the ice cream] in the microwave to melt and drink it,” Farrell told The Hollywood Reporter. “Two cheeseburgers, fries and Coca-Colas, and two slices of chocolate cake at 10 a.m. is not that fun. And I love cheeseburgers.”
The naturally lanky Colin said the weight gain not only changed his body, but dramatically affected his emotional state, according to the Examiner.
“It makes you aware of how you’ve identified being a certain way,” said Farrell. “I gasped [when I saw myself shirtless on screen]. I’d forgotten what it looked like.”
Colin’s “Lobster” co-star, John C. Reilly, said the once ripped Farrell had a “dad bod” in the film. “A dad bod is a physical manifestation of our sacrifice to our children,” Reilly joked.
Farrell’s weight gain paid off: The Lobster, which was filmed in Ireland, won the Jury Prize at the 2015 Cannes Film Festival.

In 2012, Colin followed a clean low-carb diet and did rigorous weightlifting workouts to get in shape for Total Recall.
Low-carb diets such as the ketogenic and Atkins diets promote rapid weight loss by forcing the body to burn fat for fuel, said obesity expert Dr. Eric Westman, co-author of Keto Clarity.
Farrell embarked on a rigorous training regimen that included daily two-mile runs and an hour of weightlifting six days a week, the Examiner reported.
“I’m somebody who a couple of years ago couldn’t even run a mile,” said Farrell, who went to drug rehab in 2005 after his nonstop partying spiraled out of control.
Until recently, actor Colin was a poster boy for bad behavior, thanks to his drug and alcohol addiction, but the Irish heartthrob overhauled his lifestyle once he became a dad in 2003. Farrell’s second son, Henry, was born in 2009.
“What my first son James did was allow me to care for something in this world when I couldn’t care for myself,” said Farrell. “James saved my life.”
Inspired by his desire to “live as long as possible” for his sons James and Henry Colin began working out regularly, eating better and put the kibosh on his longtime substance abuse.
“I live a clean lifestyle,” said Farrell. “I eat really well, drink loads of green tea, and take a [loads] of vitamins. I want to live for as long as possible now. I have two boys that I want to see grow up.”
