Chris Pratt may have enjoyed the three to four hamburgers he put away during the "Parks and Recreation" table reads, but he soon realized the extra weight he had packed on caused him some unfortunate side effects.

"I was impotent, fatigued, emotionally depressed," Pratt told Men's Health UK magazine (via Fox News). "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."

The 35-year-old actor has kept the weight off and bulked up thanks to his role in Marvel's "Guardians of the Galaxy." He had lost weight for previous movie roles but always gained it back for his role as Andy Dwyer on the NBC comedy.

"I'd gone back and forth, lost weight for 'Moneyball,' got fat again, then trimmed down for 'Zero Dark Thirty,' then gained it all back again for Andy," Pratt said. "That's when I saw 'Zero Dark Thirty' and right after walking out I was like: 'I'm going to get in shape and I'm never going to be fat again.'"

At his heaviest two years ago, the "Jurassic Park" star weighed 300 pounds. He linked his hefty stature to comedic appeal on "Parks and Rec."

"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," he said. "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."

Pratt also placed partial blame on his lovely wife Anna Faris, whom he married in 2009.

"We were drinking a lot of wine and having fun. I was her little Hansel out in the woods and she was fattening me up to put me in the fire," he said. "It was like Momma Bear and Papa Bear. She would eat a little bit, I would eat all of mine and rest of hers."

Pratt will next star in "Jurassic Park," which hits theaters on June 12.
