So how do dancers lose weight? I don't think they need to lose weight deliberately at all, because they need a lot of training every day to stretch their tendons, exercise some difficult flexibility and do some difficult movements, all of which need strong support from behind. If you don't eat and there is nothing in your body, your body cells can't produce strength and have no energy to learn dance.
When I was in high school, there was a dancer in our dormitory. She studies folk dance. Because folk dance requires high flexibility, she has to learn some very difficult movements every day, such as splitting shoulders or sitting on a tiger stool, and keep it for a certain time. But he eats no less than us, sometimes twice as much as us.
But overall, they are not particularly fat, which is why they need to work hard to do such actions every day. They say that after a dance class, the head is sweaty, and after a class, the clothes on the back are soaked. So many people in a class are sweating all over the floor, which is equivalent to exercise.
If they eat two servings of food every day, but when doing these actions or attending classes, they consume twice as many calories as they eat, which means they consume more calories than they eat, so they won't get fat.
Their own course is a weight-loss course, and there is no need to explain it. The most important word is exercise.
