Fat loss versus muscle loss

Weight loss characteristically involves the loss of fat, water and muscle. Overweight people, or else people suffering from obesity, typically aim to reduce the percentage of body fat. In addition, as muscle tissue is denser than fat, fat loss results in increased loss of body volume compared with muscle loss. Reducing even 10% body fat can therefore have a dramatic effect on a person's body shape. To determine the percentage of weight loss that is due to decreased fat tissue, various methods of measuring body fat percentage have been developed.
