The application discloses application of O-acyl-alpha-hydroxy acid compounds in weight loss and lipid reduction, and belongs to the fields of biological medicine manufacturing, biological medicine use and functional food development. The O-acyl-alpha-hydroxy acid compounds can inhibit weight growth of high-fat diet-induced obese model mice and reduce body fat. Compared with GLP-1 receptor weight loss drugs which achieve the effect of reducing weight by inhibiting appetite, the O-acyl-alpha-hydroxy acid compounds are not dependent on appetite inhibition, and can reduce side effects such as gastrointestinal discomfort and muscle loss caused by inhibiting appetite. When combined or sequentially administered with GLP-1 drugs, the O-acyl-alpha-hydroxy acid compounds can maintain or enhance the weight loss effect while improving the side effects caused by GLP-1, and can prevent the risk of significant weight rebound after stopping GLP-1 by maintaining body weight. The application provides a safe and effective new strategy for weight loss and lipid reduction.
