Too young to control your diet too much. Eat less and eat more, but not less nutrition. You should eat eggs and milk for breakfast, and you must eat it for dinner. If you feel hungry before eating less every meal, eat fruit in the morning and afternoon, and eat protein powder if possible.

If you exercise, you want to lose weight mainly by exercising 10 minutes or more, mainly by aerobic. However, I suggest you lift more iron when you go to the gym. After all, you are not fat, but you are more beautiful with muscles. Generally, strength training first, and then aerobic running. The strength is planned. One part every day, arms (which can be divided into two or three brachios), chest, back, abdomen and legs (chest can be three or three brachios, classic push-ups, back and two brachios, classic pull-ups). Remember to abuse the training area every time, so that there is no energy left, and the pain is obvious the next day (this is muscle repair and growth, so it is best to take more protein). If it is aerobic, the best time is more than 30 minutes, the exercise intensity is enough, and the heart rate is around 180- age (it is also said that it reaches more than 50% (220- age) and does not exceed 70%). Running suggests the next day. Finally, there should be 1 and 2 days' rest for exercise every week.
