First of all, a star should have his own image, just like having his own agent, his own special makeup artist and his own clothing collocation. Their bodies are completely under their control. Some stars specialize in fitness and weight loss for acting, and some need to cut their hair for work. In fact, these are all because of the needs of work. However, when it comes to a star's good figure, I don't believe so. I can only say that some stars are like this. There are also counterexamples. Some stars are fatter, such as Sammo Hung and Han Hong. Some stars are not very beautiful. Song Like Bao Xiao, a comedian, thinks he is interesting from the outside. Coupled with his own artistic cells, he decided to take the comedy route.
Now the stars are in good condition, and the competitive pressure in the entertainment circle is still great. Every star has his own strict standards and has high requirements for himself in all aspects, such as figure and appearance. Some stars are thinner, so find a special dietitian to match the fattening package. Some overweight stars will lose weight through various ways, such as exercise, dieting and so on.
What we see on TV is just the glamorous side of the star, and we don't really understand his life. In order to show the best side to everyone on TV or in movies, they also put in a lot of hardships behind it, which is not as simple as what we saw.
