Robert Pattinson once lost weight by eating 'nothing but potatoes for 2 weeks' and says he's tried every fad diet 'you can think of': 'It's extraordinarily addictive'

• Robert Pattinson told Evening Standard magazine that he once went on a potato-only diet for two weeks.
• As part of the detox, he said that he ate "just boiled potatoes and Himalayan pink salt."
• "Apparently it's a cleanse… you definitely lose weight," he said.

Robert Pattinson said that he's tried various dieting regimens over time, including an all-potato diet. 

"I have basically tried every fad you can think of, everything except consistency," the actor said in a cover story for Evening Standard magazine, released on Thursday. "I once ate nothing but potatoes for two weeks, as a detox. Just boiled potatoes and Himalayan pink salt."

"Apparently it's a cleanse… you definitely lose weight," he added.

Pattinson also said that he attempted the keto diet, under the assumption that he could "just eat charcuterie boards and cheese all the time."

"But I didn't realise that you can't have beer as it completely defeats the purpose," he said. 

Pattinson's comments were sparked by a discussion about the expectations and pressure men feel to look a particular way. 

"Yeah, it's crazy," he said. "And it's very, very easy to fall into that pattern as well, even if you're just watching your calorie intake, it's extraordinarily addictive — and you don't quite realise how insidious it is until it's too late."

The actor, who rose to fame with parts in the "Harry Potter" and "Twilight" franchises, has had experience with adjusting his diet and fitness routines for roles.

Most recently, for his role as Bruce Wayne/Batman in "The Batman," he worked out extensively despite joking about not doing so. and followed a strict diet that resulted in him "counting sips of water" prior to filming shirtless scenes for the superhero movie.
