The actor told the Evening Standard that he's “basically tried every fad you can think of," everything "except consistency."
“Yeah, it's crazy. Even if you’re just watching your calorie intake, it’s extraordinarily addictive — and you don’t quite realize how insidious it is until it’s too late,” he explained.
Rob recalled how one time, he ate "nothing but potatoes for two weeks" as a way to detox his body. "Just boiled potatoes and Himalayan pink salt. Apparently it’s a cleanse…you definitely lose weight,” he said.
“And I tried to do keto once," he continued. "I was like, ‘Oh, there’s a diet where you just eat charcuterie boards and cheese all the time?’ But I didn’t realize that you can’t have beer, as it completely defeats the purpose.”
Rob seemed to take a stand against the body expectations placed on men in 2020, when he told GQ that he wasn't working out consistently for The Batman, which starred him as the caped crusader.
"I think if you're working out all the time, you're part of the problem," he shared. "You set a precedent. No one was doing this in the '70s. Even James Dean ... wasn't exactly ripped."
Rob later clarified that it was a joke — and he told the Evening Standard that he just thinks it's "quite embarrassing when you get into a pattern of answering questions about your workout, because there’ll always be a guy who’s in better shape than you."
