According to recent studies, ursolic acid which is a waxy compound found in apple peel has serious muscle-building properties. Mice suffering from atrophy were given ursolic acid and this halted muscle degradation. When ursolic acid was administered to healthy mice, it actually sparked muscle growth and even reduced body fat.
Apples are low in calories and fat, low in sodium, and contain vitamins and minerals as well as fiber. These can all help you to lose weight in different ways. The fiber helps you feel full longer because it expands in your stomach so it takes less food to satisfy your hunger.
The slow digesting carbohydrates in apples also make them ideal pre-workout fuel.
