Chris Pratt is definitely one of those guys who swears by intermittent fasting — a diet/lifestyle that involves fasting for most of the day and eating only during a shortened time period.

So I’m doing this intermittent fasting thing; don’t eat till noon, try to get my cardio in in the morning. It’s super exciting actor stuff,” he joked on his Instagram story. “But I finally get my coffee and look: I’m drinking out of Minnie Mouse’s head!” he said, while lifting up his mug.

Chris clearly knows what he’s talking about. His intense diet first helped him lose weight in 2014, and he’s kept it up ever since.

“I actually lost weight by eating more food, but eating the right food, eating healthy foods and so when I was done with the movie my body hadn’t been in starvation mode,” he told People in 2014 about transforming his body for Jurassic World.“It wasn’t like I was triggered to just gorge myself and get really fat again.”
