Researchers at Japan's National Agricultural Food Research Institute believe that boiling sweet potato water can reduce weight because some protease residues in it can effectively suppress appetite. This substance has been tested in mice, and researchers say it can be replicated in humans.

The researchers tested two groups of obese mice. In addition to the normal unified feeding, one group was also fed with sweet potato peptide, a digestive enzyme component contained in boiled sweet potato water.

After 28 days, the weight and adipose tissue of the two groups of mice were measured again. 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.

The researchers said that this discovery can not only avoid wasting the water left by boiling sweet potatoes, but also make full use of this water to achieve the purpose of losing weight. Tip: Wash the skin before cooking sweet potatoes, or you will drink the sweet potato water mixed with soil to lose weight.
