Obese patients' expectation of treatment often conflicts with the actual effect, and the weight loss effect often fails to meet the ideal requirements of patients. The difference between patients' expectation and weight loss effect brings problems to clinicians and patients. Generally speaking, most patients can lose 5% ~ 15% after treatment, which is a reasonable weight loss goal. To achieve this goal, the specific implementation should be adjusted according to the different conditions of patients, and a feasible weight loss plan should be formulated. The design of weight loss plan and the setting of goals are important factors to determine the success of weight loss. The goals of the elderly may be different from those of young people, and the elderly may pay more attention to maintaining weight. The implementation of the weight control plan needs the joint efforts of dieters and professional clinicians, and the goal setting should be implemented step by step. After the initial goal is achieved, new goals should be set. You will lose weight faster at first, and then you are allowed to lose 0.5 ~ 1 kg a week. In fact, even if you only lose 5% of your original weight and gain a healthier physique, it can be called weight loss success.

There are many examples of unsuccessful weight loss, so obese patients often complain about the failure of treatment and think that "treatment is ineffective." In fact, although there are many treatments for obesity, fundamentally speaking, obesity is a chronic disease and it is difficult to completely cure it. After the treatment stops, the weight will rebound.

This is similar to the situation that blood pressure and blood lipid will rebound after hypertension patients stop taking antihypertensive drugs, and blood pressure and blood lipid will rebound after hypercholesterolemia patients stop taking antihypertensive drugs. Obesity is as difficult to cure as these chronic diseases. Many patients can only be relieved and controlled. Once the treatment is stopped, the risk factors will rise again. The efficacy of weight loss can be evaluated according to the following points.

(1) The ideal result is that the patient loses more than 15%.

(2) The satisfactory result is a weight loss of 5% ~ 15%, and the patient can maintain this weight in the following years.

(3) The satisfactory result is that the body weight is 5% ~ 15% lower than the basic value, and the subsequent rebound is not higher than the population weight growth rate.

(4) The undesirable result is that the weight loss is below 5%, and the rebound speed is higher than that of the general population.

Generally speaking, if you can lose 5% ~ 15%, you will be healthier. Good therapeutic response appeared, including lowering blood pressure, lowering the levels of total cholesterol and triglyceride in blood, raising high density lipoprotein cholesterol and better controlling blood sugar of diabetic patients. Fatigue, asthma, hyperhidrosis, joint pain and other symptoms caused by obesity will be significantly reduced, and women's menstrual disorders will also be improved.

Many scholars believe that losing weight is not as fast as possible. The safest weight loss speed is no more than 1kg per week, that is, you can only lose 4kg of body fat at most every month.

The speed of losing weight should be appropriate. If you lose weight too slowly, it is easy to lose confidence and patience. If you lose weight too fast, it will also damage your health. Middle-aged people are most likely to gain weight because of their slow metabolism. However, due to the gradual decline of physical function, especially the heart function, they can't bear the pressure they could bear when they were young, so drastic weight loss methods, such as excessive strenuous exercise or taking diet pills, may be dangerous. If you plan to lose weight around middle age, it is best to spend a long time and lose weight slowly.
