Reducing weight,not equal to diet,weight is right,but should be appropriate,so I suggest you do more exercise,if you persist,so there is not only the diet will not thin,anorexia,on how awful!The teacher advised you "1.2.3) running swimming ate less (eat less not equal to not eat) 4 badminton...wait,because a lot of weight and dieting,but broke his body!
Yours 某某
