A weight loss of 5 to 10%, regardless of the method by which it is achieved (physical activity, calorie restriction, pharmacological treatment), improves quality of life, biological markers and clinical parameters.
The benefits of this weight loss last as long as they last. As a rule of thumb, long-term weight loss will achieve its goal if the patient does not gain more than 3 kg for two years.
Factors in maintaining weight loss:
Despite the variety of treatment approaches in an initial weight loss program, most patients achieve their maximum weight loss in the first six months.
When you lose weight, energy expenditure drops by about 20 per kilogram of weight loss. The initial program alone (or rather the initial calorie deficit) is therefore ineffective and no longer sufficient after weight loss.
The weight change relates to the desired weight from the start of the program before the maintenance process. Achieving the desired weight after this first step rewards patients’ efforts and gives them long-term confidence in their ability to lose and maintain weight. It is therefore important to avoid unrealistic goals in grooming. Rapid weight loss, which has long been viewed as an obstacle to long-term maintenance, can also be a great way to aid patient motivation.
Recognizing the emotional triggers of hunger attacks for better control also contributes to weight maintenance success. Furthermore, this maintenance only takes into account its effectiveness when accompanied by a flexible attitude. Hence it is necessary to avoid rigid management of the diet in an all-or-nothing mode.
The all or nothing mode of operation sometimes indicates eating disorders, which are seen as an obstacle to maintaining weight loss.
Obstacles to maintaining weight loss:
In normal clinical practice, obesity is not really viewed as a chronic disease like diabetes or high blood pressure that requires long-term follow-up.
Not surprisingly, in this regard, patients no longer receive adequate follow-up visits after the period of weight loss. Maintaining weight loss after a previous weight loss program puts patients in a new metabolic and endocrine balance. In fact, weight loss is associated with physiological survival mechanisms, such as a decrease in basic metabolism and lepton levels, a strong central trigger of hunger.
Note that patients need to observe and reinforce behavioral changes that have promoted diet and physical activity weight loss. On this point, most studies agree that it is necessary to maintain multiple changes in order to maintain weight loss well. An attitude that seems difficult as many patients quickly return to their old bad habits.
In general, learning new behaviors should go through an acquisition phase followed by constant repetition. During the integration, the subjects need less and less effort to complete it.
