I think as a female star, it is their job to keep beautiful appearance and keep weight. After all, as a public figure, you have to rely on acting besides filming. At other times, participating in various fashion activities or advertising depends on your face value and body shape. As for why they can keep such a good figure, I think there are the following points:

First, eat less carbohydrates.

Female stars are very concerned about their bodies and don't eat whatever they want like ordinary people. Basically, they must be isolated from carbohydrates. Joey Yung, a Hong Kong singer, once revealed that she likes rice very much, but now she basically doesn't eat rice because she wants to keep fit after becoming a star. Actor Yang Mi once revealed that he ate seven jiaozi for lunch and only vegetarian salad for dinner. For me, it takes fifteen steps to eat jiaozi. You can think about the restraint of female stars on carbohydrate food. They eat very little.

Second, keep fit and exercise regularly.

I like watching Weibo, a female star. Besides showing off their beautiful faces every day, they also like to punch in at the Weibo for fitness. Nowadays, female stars are not only thin, but also thinner than lines, so they basically insist on exercising every day. The most famous is Mabel Yuan, who exercises by practicing vest line, so you can exercise in her Weibo almost every day. Olivia and Tamia Liu also have very good bodies and smooth lines. They basically like to practice yoga by punching in the Weibo. The figure of a female star is really from practice. Although they have the conditions to ask a fitness instructor to teach alone, their perseverance in exercising is still very strong.

Third, the public is better than the United States, and their figure still needs to be shown.

Female stars should exercise, just like us ordinary people, eat less and exercise more. Because of their work, they may eat less and exercise more than us. In order to keep fit, they work harder than us. But why can they persist? Because every time there is a large-scale award ceremony and various parties, female stars will wear dresses to attend. At this time, there will be contrast, and the figure of the female star will be concerned by everyone. Female stars with good figure will also be more popular and loved by more people.

I think the above three points are the reasons why female stars can keep in such good shape. At present, the audience is still harsh on the figure of female stars. It is also a professional accomplishment that they can keep such a good figure. Anyway, female stars are really good.
