Diabetes mellitus is a chronic metabolic disease which seriously threatens people's health at present. Although new drugs for the treatment of diabetes continue to emerge, but the effect of diabetes treatment is still not satisfactory. Medical nutrition therapy (nutrition therapy medical, MNT) and exercise therapy are essential measures for prevention and control of diabetes at any stage of the natural course of the disease, especially for the overweight and obese patients with type 2 diabetes. However, at present, the majority of patients could not get the guide from nutrition specialist and sports specialist. In addition, the existing diet programs are often more complex, difficult to implement and adhere to in daily life, and exercise programs are often lack of targeted. In view of this, the Shanghai peak Sports Management Co., Ltd. developed a kind of nutritional meal replacement for weight loss. The nutritional powder has the characteristics of high nutrition, low calorie, low glycemic and strong satiety, and the heat is only 126kcal, and have a good sense of satiety. Studies have shown that 1 times a day with bags of nutritional meal replacement instead of 1 meals for obese people have a role in weight loss. In theory, the meal is also suitable for diabetes patients, especially overweight and obese type 2 diabetes, such as the combination of individual exercise prescription may be better, but there is still a lack of relevant research. In view of this, we proposed a joint sports workers, explore nutritional and individualized exercise prescription intervention on overweight and obese type 2 diabetes mellitus, to explore suitable for China's diabetes lifestyle intervention measures, improve the level of prevention and treatment of diabetes in China.
