HW: Do you think diets are useful or not? Why?

I think diet control is a great help in keeping the body healthy. But it is never recommended that you do nothing but control your diet! This behavior is not good for your health because it is a muscle-reducing action, not losing fat. Therefore, I think we should exercise together with proper diet. I think we should keep our weight steady because obesity and overweight can cause various diseases to come. Even for skinny people, I think it\'s important to measure the amount of muscle and maintain the right amount of muscle in your body. (I recently took a life science class, so I explained it in detail.)
