Anyone can lose weight as long as it is healthy. And I don't think you are fat. Sometimes weight does not reflect a person's fatness. As long as you don't accumulate fat and look in good shape, you can't say you are fat. But girls love beauty and always want to be thinner, but they should pay great attention to their health.

You can choose to jump rope. You can jump 500 times first, and then gradually increase it every day, but you must do stretching and muscle relaxation after jumping, otherwise muscles will appear. Hula hoop is also a good choice, but when you turn a hula hoop, you can't wait until you are hungry or full to digest it just right, otherwise it will be bad for your health.

Don't go on a diet at ordinary times, eat three meals normally, but it can be light and less greasy, but you must supplement enough vitamins and protein and other nutrients, because you are in the developmental stage, and your health will be affected if you don't pay attention.

You can also pay more attention to your usual living habits. When sitting, you can straighten your back and don't bend over. This is a small detail in life, but it is actually very important.

I hope it helps you.
