I am a dancer, with a height of 163 and a weight of 100 Jin. The teacher said that I was not thin enough to lose weight, but I tried many methods, but I couldn't lose weight.
Diet control is one way. Eat a little less and a little more fruit per meal, and stick to it, but not too little. I know that dancers often need leg strength to practice somersaults, so don't over-restrict their diet. My best friend is a dancer. I saw her lose weight in this way. She is about your age. 100 kg is actually not fat. How can you learn to dance without a good foundation? Just 96~98. Not too thin.
