With the improvement of people's living standards, we pay more attention to physical health while pursuing rich material life. Dieters are born to meet the needs of social health and rise in developed countries in Europe and America. This profession combines the characteristics of nutritionists, health workers, medical practitioners, traditional Chinese medicine, psychologists and other occupations. Combining the health concept of "scientific diet, reasonable exercise, good lifestyle and continuous real-time monitoring" is the most scientific and effective healthy weight management method at present.

At present, in the world, the number of fat people has surpassed that of thin people! China surpassed the United States with 43.2 million men and 46.4 million women, making it the country with the largest obese population in the world. Weight control is urgent! Obesity not only induces potential diseases, but also affects all aspects of life and work, such as inferiority complex, failed marriage, lack of friends and so on. Overweight will obviously increase the incidence of cardiovascular and cerebrovascular diseases, tumors and diabetes, and it is also easy to suffer from osteoarthropathy, fatty liver, gallstones, gout, obstructive sleep apnea syndrome and endocrine disorders. Being underweight means malnutrition, which will affect the normal development of minors' body and intelligence. Low-weight adults can have a variety of pathological manifestations, such as decreased labor ability, bone loss and fracture, gastrointestinal dysfunction, low immunity, irregular menstruation and amenorrhea in women, anemia and depression. Weight control is to protect health, prolong life and improve the quality of life.

In recent years, "weight management" has quietly entered China, and many health care products brands and health management institutions have successively launched their own "weight management" products and services. However, the products in the healthy market are uneven and lack of quality assurance. Health management agencies target high-end consumer groups, and professional nutritionists charge high fees. For mass consumers, the ideal "weight management" is unsustainable.

Weight managers are professionals engaged in weight control management guidance, weight control management, dissemination of food nutrition and safety knowledge, and promotion of public health. Health care industry, public health care field, catering service industry, consulting industry, slimming professional institutions, etc. Everyone needs the supply of weight management talents, facing the talent "famine", and the employment prospects are very broad.
