First of all, because of professional reasons. In this age when thinness is the beauty, everyone thinks that a woman who keeps slim looks good. If a female star can't keep a good figure, she will be spit out by the public, and she may soon lose her powder and eventually be forgotten by everyone. Therefore, female stars have to keep their faces and bodies in order to be loved by the public and make money by fire.

Moreover, female stars mainly rely on their faces and bodies to eat, and it is most basic to keep a good figure. Otherwise, when you play some roles, you are fat and out of step with the role, which is naturally inappropriate. Like many female stars, they try to lose weight in order to match the protagonist image in movies or TV, so as to get the film pay and have money to live.

In addition, the taller modern people are, the more they pay attention to maintaining and managing themselves. It can be said that most female stars live at a high level, rich and famous. Such people are more cruel to themselves and will pay more attention to physical management. Like Andy and Jiang, fitness is a common practice, and three meals a day also pay attention to balanced nutrition, so the body naturally stays excellent.
