Chris Pratt – 41-Years-Old, Guardians of the Galaxy

Actor Chris Pratt has one of the most fantastic fitness stories in Hollywood. Many came to know and love Pratt as the goofy, overweight bro Andy Dwyer on Parks and Rec. However, after the show ended, Pratt lost all the weight, becoming ripped for the Guardians of the Galaxy films.

So how did Pratt turn it around? He says it’s all about mindset. “What you want is instant results when you’re out of shape,” Pratt explained recently. “But when you’re in shape, you know it’s the result of doing a little bit every day. So instead of ‘Boy, I’d love to eat this hamburger right now,’ I’m thinking, ‘I eat that hamburger and that’s 1,200 calories, and I’m gonna work out tomorrow and burn 800 calories. I may as well eat a salad here, still do that workout, and then I’m actually making progress.’ ”
