The results showed that the weight of a group fed with sweet potato peptide decreased significantly, and the content of leptin protein, known as obesity killer, increased significantly. Leptin protein has always been considered as a hormone that can increase satiety and reduce appetite. In addition, cholesterol, triglyceride and adiponectin in this group of mice decreased.
