Ursolic acid from apple peels could help to fight obesity by increasing calories burned, according to new research in mice.
The study – published in PLoS ONE – suggests the natural substance found in apple peel can partially protect mice from obesity and some of its harmful effects.
Led by Dr Christopher Adams from the University of Iowa, USA, the researchers noted that ursolic acid – a waxy substance found in apple peel – increases muscle and brown fat mass in mice fed a high-fat diet. The research team revealed that mice supplemented with the compound in addition to a high fat chow burned more calories and had a reduced incidence of obesity, pre-diabetes and fatty liver disease and increased skeletal muscle, than mice not receiving the supplement.
Previous studies have shown that ursolic acid increases muscle mass and strength in healthy mice.
