15 of 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. And 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.

You may remember Jennifer Hudson from her first appearance on American Idol over 10 years ago. But since then, she’s dropped over 80 pounds — and managed to keep it off all this time.

So, what’s her secret? ABC News says Hudson watches her diet (remember — she was a Weight Watchers spokesperson for several years) and doesn’t give in to the temptation of comfort foods. She does always have chocolate on hand, though, as this is her one vice to keep her sane.

Here’s a celeb whose weight is always yo-yoing for roles. But right now, Jonah Hill looks slimmer than ever. Us Weekly explains Hill had to gain 40 pounds for his role in War Dogs, but he’s since lost the weight by keeping a food journal and listening to the advice of his nutritionist. He also listened to the advice of Channing Tatum, who suggested eating less and following the guidance of a personal trainer.

You’re probably still playing Aretha Franklin’s timeless music today. And a few years back, she lost a ton of weight — 85 pounds, to be exact. People.com reports Franklin had surgery at the time, which caused her drastic weight loss. It wasn’t gastric bypass, however — in fact, she didn’t tell the publication what she underwent. But she did say the doctors told her this surgery would make her feel 10 to 15 years younger, and she certainly looks it, too.

At 65, Kirstie Alley stuns by looking slimmer than she ever has. Us Weekly reminds us Alley rejoined the Jenny Craig program as a spokesperson in 2014 after gaining back about 30 pounds over the years. Since then, she’s dropped 50 pounds. She accomplished this by looking at lifestyle changes she could sustain forever instead of quick-fix dieting. “My goal is to keep this and maintain this throughout my life,” she says.

June Shannon, better known as Mama June, is well established in the reality TV business with her hit show, Here Comes Honey Boo Boo. You probably remember June for her robust figure, but Women’s Health reports she went from 460 pounds to a size 4. And she did this the old fashioned way — by watching her diet and ditching all the soda she used to drink.

Mama June also has a sweet tooth, and her trainer recommends eating watermelon to satisfy those cravings. And as far as the soda is concerned. she drinks Propel flavored water as a low-calorie swap.

Not all celebrities lose the weight in a super healthy way. Jimmy Kimmel tells Men’s Journal he took drastic measures to lose the initial 25 pounds, and since then has taken to two days of starvation a week to maintain his weight around 180 pounds. On Monday and Thursday, Kimmel says he eats less than 500 calories a day by drinking coffee and eating a lot of pickles. On the remaining five days of the week, he eats huge portions of whatever he wants. We don’t recommend this approach, but we have to say — it seems to be working.

Many fans loved Chris Pratt for his looks before he lost the weight, but now, the Guardians of the Galaxy star is looking fitter than ever. Men’s Fitness reports he lost around 60 pounds in six months with his extreme workout plan. His workouts incorporate P90X and a range of cardio exercises, like running, swimming, and participating in triathlons. And Pratt’s not in the business of cutting calories, either — he still eats around 4,000 calories a day when he’s training this much, and he drinks a ton of water.

Fox News reports she keeps to a healthy diet and works out five days a week, which includes a mix of strength training and cardio with a trainer for three of those days.

You probably remember Khloe as being slightly bigger than her sisters a few years back, but those days are long gone. Entertainment Tonight says this Kardashian lost 40 pounds overall, and she did it by making nutrition and fitness a priority after her painful divorce. “By keeping positive about your body, your inner health, your mental sanity, your fitness, and what you’re trying to achieve, you’re way more likely to succeed,” she said.
