Obesity is a nutritional disorder accompanied by the continuous improvement of people's living standards, which is caused by excessive nutrient intake or insufficient use of energy stored in the body. Obesity not only brings inconvenience to people's daily life, but also causes cardiovascular diseases and diabetes.

During the period of 1996, Fujian Institute of Traditional Chinese Medicine conducted a study on the slimming effect of drinking Tieguanyin on 102 adult simple obese men and women. Studies have shown that Tieguanyin contains a lot of tea polyphenols, which can not only improve the function of lipolytic enzyme, but also promote the metabolic activity of neutral lipase in tissues. Therefore, drinking Tieguanyin can improve the body shape of obese people, effectively reduce the subcutaneous fat and waist circumference of obese people, and thus lose weight.

People's Hospital of Quanzhou City, Fujian Province used Tieguanyin slimming tea to treat 164 obese patients, taking slimming tea 12 ~ 14g every day, 15 days as a course of treatment. After two courses of observation, the patients' blood lipid, triglyceride and cholesterol decreased obviously, and their weight also decreased, and the total effective rate reached over 70%.
