近年来,随着生活水平的提高,人们再也不必为营养不良而担忧,但同时却出现了一个令人烦恼的营养过剩的问题。 目前,西方发达国家的人口肥胖率高达30％。在我国,肥胖者所占比率也呈明显上升势头。据京、津、沪三地统计,每年住院减肥者均达上万人次,到健美中心、气功减肥班减肥的人更是不计其数。 In recent years, with the improvement of living standards, people no longer have to worry about malnutrition, but at the same time there is a troublesome problem of overnutrition. At present, the obesity rates of developed countries in the West are as high as 30%. In our country, the proportion of obese people also showed a clear upward trend. According to statistics of Beijing, Tianjin and Shanghai, the number of hospitalized people who lose weight every year has reached over 10,000. It is even more numerous among people who use the fitness center and lose weight in the Qigong diet class.
