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 at one point or another in their careers.
There is no one reason why someone may want to lose or gain weight, but either way, celebrity weight (loss or gain) 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.
Even more interestingly though, there have also been a number of Hollywood stars who have gained weight for the sole purpose of a movie role. Stars like Ryan Gosling, Matthew McConaughey, Christian Bale, Jared Leto, and Charlize Theron have all sought to take on more pounds for their massive roles in the film industry.
