Mila Kunis – 20 Pounds
Co-starring alongside Natalie Portman in the movie Black Swan required Mila Kunis to lose 20 pounds as well. She set out to achieve this goal by limiting the number of calories she consumed to 1200 per day and smoking a pack of cigarettes daily. At the end of it, she weighed just 95 pounds – which isn’t entirely unhealthy for a woman of her stature. Once filming ended, the actress decided to gain back 25 pounds. Her net worth of $65 million investment money allows her to live very comfortably – now and after she’s retirement too!
