A study involving mice finds a compound in apple peel called ursolic acid may curtail obesity by increasing muscle tissue and boosting calorie burning. As well as the weight control benefit, it could deter fatty liver disease and pre-diabetes also. In the research released in PLoS ONE, all of the mice were fed a high fat diet, but just half of them received meals augmented with ursolic acid. Although the half that received the ursolic acid ate even more, they gained less pounds. Additionally, the investigators found they burned more calorie consumption, had more muscle tissue and displayed greater stamina compared to the combined group who did not receive the substance. Furthermore, their blood sugar levels were near normal plus they did not incur weight problems related-fatty liver disease.Related StoriesWhy do we sleep?
