I've heard that some people diet, fast, or even do bulemic/anorexic behavior, to stay slender, especially female models. What are methods for staying lean?

Well, the big problem with calorie restriction is that the body becomes more resistant to insulin, which means your body releases more of it when it’s not needed. Which leads to the formation of more fat. To avoid that, you’ll want to find a way to get more calories into your body without relying on eating them.
