Renee Zellweger – Gained 20 Pounds
Renée Zellweger put in a lot of effort to land Bridget Jones’s role in the cult comedy Bridget Jones’s Diary. She was too thin at first, so she changed her diet and went on a calorie-counting binge with pasta, chocolate bars, butter, milkshakes, and other high-calorie foods. Well, it doesn’t sound so bad if we eat whatever we want. The actress gained 20 pounds in no time, landed the role, and then slimmed down to her beautiful figure again.
Chris Pratt – 30 Pounds – Diet & Exercise
Pratt was determined to win Scott Hatteberg’s role in the film Moneyball after being rejected for being too heavy. Pratt lost 30 pounds and sent a photo to the casting director, and he was cast right away. He was so taken with his new look that he continued to bulk up, eventually transforming into the Hollywood hunk we all know and love. In 2014, he lost the most weight of his life, dropping 60 pounds in just six months for his role as Peter Quill in Guardians Of The Galaxy.
