You must have enough nutrition at your age, because you are still growing, but your diet needs to be adjusted. Don't eat foods containing sugar and high fat. White rice contains more starch, so eat less and eat more other vegetables, fruits and cereals.

There is also exercise, which is easier and simpler than jogging. Jogging is aerobic exercise, which can accelerate fat consumption and achieve the goal of losing weight quickly. Jogging time depends on the jogger's training level. For beginners or people who have stopped exercising for a long time, it is best not to exceed 10 to 15 minutes at the beginning of each exercise, and there can be a slow walking process in the middle. Jogging time can be gradually increased to 20 minutes in one month. The key to jogging is persistence, and you need to train three times a week on average. If you persist, you can take part in the marathon in four to five years.

Your goal is terrible. For the average person, the normal metabolism of fat is about 8- 10 kg a month, that is to say, losing weight about 8 kg a month is the limit, because the metabolism of fat is not so fast, so losing too much is just water and protein, which is easy to rebound, but the heart can't adapt. Study hard, work hard and have a good rest. You don't have to think about losing 85 pounds a month, so you will naturally lose weight. My brother graduated from high school a year ago and weighed 178 kg. Because he can't go to college, he loves to eat and sleep, but he is more tired than before. Now he 132 kg. But the skin contraction can't keep up with the weight, and it's a little slack, like the stretch marks of others after giving birth to children. So slowly lose weight, the most important thing is health, don't worry.
