The main way for teenagers to lose weight is to combine diet control with exercise. In terms of diet, they don't eat fast food, fried food, puffed food and drinks, at the same time, they increase a certain amount of exercise and do aerobic exercise for 30-40 minutes every day, including running, skipping rope, swimming and cycling. It is suggested that patients eat less greasy food, not spicy food, and at the same time develop good living habits, go to bed early and get up early, and the daily intake is less than the output, which can achieve the effect of losing weight. Calculate the standard weight according to the patient's height. The simple formula is negative height 105, which is the standard weight of patients. Then, control the total intake of carbohydrates, fat, protein, fruits and vegetables according to the calories of 30 calories per kilogram of body weight, and distribute the three meals according to 1/5, 2/5 and 2/5. It is suggested that teenagers strengthen physical exercise instead of dieting, because teenagers are an important period of growth and development. If they overeat, it will lead to nutritional deficiency, which will affect their growth and development and lead to the decline of their immunity. Adjust the diet structure, eat more fresh vegetables and fruits, eat less high-calorie and high-fat foods, and don't eat fried foods. Usually do more aerobic exercise, such as playing basketball, skipping rope, running, sit-ups and so on.
