The simplest way to lose weight is the abdomen, chest, thighs and other obvious places. The method is also very simple, that is, a healthy and reasonable diet plus appropriate exercise, and attention should be paid to avoiding excessive intake of high-calorie food or dieting in the diet. Nutrition must be balanced and appropriate. There are many choices for sports. You are only 19 years old. You can choose brisk walking, jogging, swimming or even skipping rope to lose weight, but you must keep it at an acceptable intensity for more than half an hour ... I used to jog for an hour at a time to lose weight, but the intensity level was not too tired. I lost 50 pounds three times a day, one hour each time, and then gradually reduced the intensity, and the time did not rebound. I forgot to mention that there are several unexpected benefits of exercise to lose weight. First, the skin looks better and better, and it hasn't grown acne for a long time.

Lose weight and you will find yourself different.
