The classic diet, or the managing consumption of food and drink with the intent to lose, gain, or maintain weight, is something celebs of all shapes and sizes from all walks of life have done before.
There is no one reason why someone may want to lose or gain weight, but either way, celebrity weight stories are usually rather impressive. Some celebrities have lost weight due to problems that come with age, and other celebrities have decided to shed some pounds for their health.
Quite interestingly, there have also been a number of Hollywood stars who have lost (or gained) weight for the sole purpose of a role. Stars like Matthew McConaughey, Anne Hathaway, and Renee Zellweger have all gone on the journey of losing weight for the big screen, while stars like Christian Bale, Jared Leto, and Charlize Theron sought to take on more pounds for their roles.
