Medically speaking, first of all, only simple obesity is suitable for weight loss treatment, and other diseases such as hypercortisolism, hypothyroidism and other secondary obesity can not be treated with the weight loss plan to be introduced later. Secondly, you should combine your body mass index and waist circumference to determine whether you need to lose weight. Body mass index allows us to exclude the influence of the body when measuring obesity. Determining central obesity according to waist circumference can evaluate the harm of obesity to the body and make weight loss more beneficial to health.

According to the standards of the Special Steering Working Group of the International Obesity Conference in 2000, Asian body mass index >: 25 kg/m2 is defined as obesity, and 23~25 kg/m2 is overweight.

According to this standard, if your weight and waist circumference are in the normal range, you don't need to lose weight; If both of them exceed the standard, or the body mass index is normal and the waist circumference exceeds the standard, you need weight loss treatment. For people whose body mass index slightly exceeds the standard and whose waist circumference is within the normal range, * * Under the guidance of a doctor, determine whether the body mass index exceeds the standard due to the increase of muscle weight. If so, there is no need for weight loss treatment; If the increase of body mass index is really caused by the increase of body fat, you need weight loss treatment.

Because the medical weight loss program is formulated for obese patients, some methods, such as surgery and drugs, may cause unnecessary harm to the body when used in normal people, and the effect may not be obvious. These people should only adopt scientific diet and exercise methods, not other methods to lose weight. Dietary calorie restriction must ensure the intake of essential nutrients in the body, especially the dietary calorie restriction of normal people.

Because eating fruit forces the body to adapt to a long-term extremely low-calorie diet, the weight adjustment point is lowered, and the original energy metabolism balance will be broken. If the calories exceed the standard slightly, it will be converted into fat and stored, which will easily lead to obesity. Excessive restriction of dietary calories may also cause anorexia nervosa, endangering health and even life. In addition, young women who pursue slim beauty should not blindly lose weight, and abuse all kinds of weight-loss products and weight-loss therapies that claim to have magical effects on the market, which will pay unnecessary health costs and economic losses for weight loss.
