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.

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.
