Eating apples helps to lose weight, but it can't effectively lose weight. In the process of losing weight, it is necessary to control the total daily intake of calories, including carbohydrates, fats, protein and fruits. Eat more whole grains and fresh vegetables rich in dietary fiber, eat less high-calorie and high-fat foods, and increase a certain amount of exercise, so that you can lose weight even if your intake is less than your output. In the process of obesity, there are genetic and environmental factors, as well as obesity caused by the use of certain drugs. The main environmental factors are sedentary, overeating, too little exercise, or an increase in the number of meals and supper, which are the causes of obesity. When the input exceeds the output, the body will store excess energy in the form of fat, resulting in obesity. Although the sugar in apples is not high, it can't play a good role in losing weight. Patients should increase some exercise. Eat less apples, just a small amount between meals.
