Stars are so thin because they deliberately keep fit. Once the stars gain some weight, they will be abused by netizens, especially some idols. Everyone thinks that idols should pay more attention to physical management, otherwise they don't love their careers and don't make progress. Most stars, in front of the camera, may be 1 to 2 times fatter. If they are not thinner than normal people, they are easily criticized and abused. The thinness of most female stars in China is also exaggerated, but they look just right in front of the camera, and some female stars will look fat in front of the camera.
Both China and Korean stars have high demands on their own weight. For example, some female stars are taller than 1.65 meters, but they are absolutely not allowed to weigh more than 90 kg. It may also be because of a phenomenon of aesthetic fatigue, so most people think that chubby is more beautiful now, but if the female star is chubby, there are few roles to choose from.
These stars have to put up with the rules of this industry while eating dinner. For example, if the company requires the weight and image of female stars, then female stars must comply with the company's regulations and public preferences. Most of the stars are filmed in summer, and even if the temperature exceeds 30 degrees and 40 degrees in winter, they need to wear down jackets to shoot. Moreover, it is necessary to shoot a summer play in winter, and the whole person is shivering with cold.
