1. Khloe Kardashian
After Khloe’s marriage with Lamar Odom ended, she gained a lot of weight because of all the stress she had to go through. Later that year in 2013, she started her weight loss program and lost 40 lbs. What Khloe did was follow a strict eating plan, she cut all intake of dairy products and began an intense workout program which required her to get up at 5:00 AM every morning.
2. Natalie Portman
Although Natalie Portman was never overweight, she had to lose 20 lbs for a role in the movie ‘Black Swan,’ where she played the character of a professional ballerina. The actress had little portions of food for almost a year and was successful to achieve the required weight for the role. She did not do a lot of exercises as the director wanted her just to look skinny and not healthy.
