See the most shocking celebrity weight gains, that really changed the way these famous people look, at least temporarily. From Jared Leto to Oprah, here are the celebs that were really transformed by gaining a lot of weight.
After being declared on of the sexiest women in the world thanks to the daisy dukes and crop top she wore in “The Dukes of Hazzard”, Jessica Simpson quickly gained weight and loves her curvy body.
Jessica's pregnancy weight gain was also impressive, but the singer and entrepreneur decided she’s never going back to being skinny. “Curves are better, I don’t get the whole rail thing. It’s not good for your heart, it’s not good for your mind; it’s emotionally destructive, it really is,” she told Us Weekly.
While Jared Leto recently won the Academy Award for his performance in “Dallas Buyers Club”, after losing around 40 pounds, he was also open to gaining weight for roles in the past. For “Chapter 27”, he had one of the most shocking celebrity weight gains: 60 pounds. He ate entire Domino’s pizza, but also doubled up on dessert. “My little trick was, I would take pints of chocolate Häagen-Dazs and put them in the microwave and drink them,” he told Jimmy Kimmel.
Gaining weight for her role in “The Help” was more difficult for Jessica Chastain than for other actors, because she’s a vegan. Her key to packing on the pounds and getting the right curves for the role was eating plenty of soy. Just like Jared Leto, she microwaved soy ice cream and drank it to gain weight.
Famous for her yo-yo dieting, Kirstie Alley had one of the most shocking celebrity weight gains right after she stopped being the face of Jenny Craig. After losing 75 pounds, she gained most of it back and was almost unrecognizable when she weighted over 200 pounds. Luckily, she’s gotten rid of most of it and got back in shape for “Dancing with the Stars”.
While Russell Crowe is always open to gaining or losing weight for a role, his biggest transformation was for the movie “Body of Lies”. He put on 63 pounds, his cholesterol levels skyrocketed and he even had trouble getting out of his car. “The most frightening thing was having to rock back and forwards to get out of a car. Instead of stepping out, I had to tip myself out,” he explained.
Since she’s always been slim, Renée Zellweger went through the most shocking celebrity weight gains twice when she portrayed Bridget Jones. Gaining around 30 pounds for the movie and its sequel, the actress tried two different approached, both stuffing herself with pizzas and donuts and getting the help of a nutritionist to gain the weight, then lose it again.
Forced to gain weight to portray Marilyn Monroe in the 2011 movie “My Week with Marilyn”, Michelle Williams managed to get the curves without any dangerous calorie bombs. Her secret to getting to a size 14? “I wasn’t watching what I ate, let’s put it that way,” she told People Magazine.
While K-Fed still had the body of a dancer when he married Britney Spears, he had one of the most shocking celebrity weight gains after the divorce. After going up to 240 pounds, Kevin Federline tried to lose the extra weight on the VH-1 show “Celebrity Fit Club”, but didn’t exactly get back to his ideal weight until 2013.
The former member of Black Eyed Peas has always watched her weight, but when she starred in the movie “Nine”, she had permission to eat anything. Fergie ended up gaining just 17 pounds, but got a lot curvier with the help of co-star Penelope Cruz. “We were eating our brains out. We ordered everything fried and full of fat and salty,” she told USA Today.
While Oprah’s weight has been going up and down for decades, the truth behind one of the most shocking celebrity weight gains is that she used her thyroid condition to eat anything when she gained the most weight. Even though she struggled when she weighted over 200 pounds, Oprah vowed in 2010 to stay away from dieting.'
