Chris Pratt has opened up about his 'yo-yo dieting' after hitting what he now feels is a "great" weight.

Speaking in July's issue of Men's Health, the Jurassic World actor revealed how he lost weight for his leading man roles after reaching 300lbs when filming Parks & Recreation.

He said: "I saw myself in an episode and in the matter of two moments very close together, I thought, 'Oh my God, I'm getting fat.' And then almost immediately I did something else and I thought, 'Holy crap, I've never seen myself funnier.' And I put the two together."

His first weight loss session was for Moneyball, before putting it back on - then losing it once again for Zero Dark Thirty and back on once more for Parks.

Pratt revealed he saw it as a challenge to bulk up for Parks, explaining: "I said to the creators that I wanted to get fatter for the role. They loved it. I announced it to the whole cast, and then it became a bit of a game: how fat can I get and how fast can I get that fat. I would eat three or four cheeseburgers at every table read [of a script]."

However, he added he hated how he felt when he was bigger: "I was impotent, fatigued, emotionally depressed. I had real health issues that were affecting me in a major way. It's bad for your heart, your skin, your system, your spirit."
