The Most Extreme Celebrity Weight Loss Success Stories (and How They Did It)

From Jenny Craig to Weight Watchers, celebrities everywhere are hopping on the weight-loss bandwagon — and they’re getting paid big bucks to do it. But money aside, many famous folks are also shedding the pounds in pursuit of a healthier life.

With the help of diet and exercise (and in some cases, surgery) these celebs have gone through extreme transformations. In fact, we can’t even believe what they used to look like compared to their current physiques. Here, we take a look at the most extreme weight loss transformations of some very famous celebs.

1. Roseanne Barr

The star of Roseanne has made headlines lately as she films a reboot of her popular ’90s sitcom. But Roseanne Barr has also made headlines due to her tumultuous weight loss journey, which included gastric bypass surgery in 1998. Between Barr’s procedure and her dedication to weight loss basics, she’s maintained a healthy weight — a far cry from her 350-pound frame in the ’90s.

She told US Weekly, “I’m just doing the things you’re supposed to do. You know, moving more, and eating less.” Barr also openly credits a tummy tuck and breast reduction for her svelte frame.

Many fans loved Chris Pratt for his looks before he lost the weight, but now, the Guardians of the Galaxy star looks fitter than ever. Men’s Fitness reports he lost around 60 pounds in six months with his extreme workout plan.

Pratt’s workouts incorporate P90X and a range of cardio exercises, like running, swimming, and participating in triathlons. And he’s not in the business of cutting calories, either — the father of one still eats around 4,000 calories a day when he’s training this much, and he drinks a ton of water.

When Adele burst onto the music scene in 2008, she was significantly heavier than she is now — and she wasn’t ashamed. She once told People, “I’d lose weight if I was an actress and had to play a role where you’re supposed to be 40 pounds lighter, but weight has nothing to do with my career.”

The birth of her son in 2012 did prompt Adele to be healthier, however, as she quit smoking and stopped drinking 10 cups of sugary tea daily. Her nutritionist cited “a really clean diet, with lots of fruit and vegetables, plus lean protein and complex carbohydrates” for Adele’s slimmer figure. Regardless, Adele maintains that she’d “rather have lunch with friends than go to a gym,” according to Rolling Stone.
