Chris Pratt: Cute baby fat turns to adult obesity fast

As Andy Dwyer, Chris Pratt didn't look bad, per se--in fact, his character was so loved because he was tubby-sloppy. When he began "Parks and Rec" in 2009, he was only 30 so he could sport the frat boy beer paunch and get away with it. In your twenties, you can slam booze, brats, and carnie food.

You can ignore exercise because the metabolism is so high. After 30 the metabolism slows, and you go to seed fast if you keep up the fast food/no fitness regimen. That charming little brewski bump goes down hill literally.

And that's not charming at all. For the role of Star-Lord, Pratt had to whittle down the pudge and tone up the brewer's droop. He didn't just lose weight--without exercise weight losscan make you just saggy skinny. Chris converted the extra 65 pounds in muscle. He dropped fat pounds and added good lean ones.

Looking good is feeling good

Pratt says when you lose weight and get fit, you feel fantastic (Khloe Kardashian is nodding here). You can chase blues away just by clearing your plate of junk food, adding exercise andeating in moderation(Tyra Banks agrees it's about common sense,not dieting).As you lose obesity, you're wasting depression and negativity.

You have more energy, and you want to do things instead of dreading getting out of bed. And that positivity and health inside radiates outside. After weight loss, you look happy because your insides are happy. Isn't it nice to find a vicious cycle that works for good?
