In terms of medicine, health, or physical fitness, weight loss refers to a decrease in total body mass caused by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue). Weight loss can happen unintentionally as a result of malnutrition or a condition that is underlying it, or it can happen as a result of a conscious effort to treat an actual or perceived overweight or obese status. Cachexia is a term used to describe "unexplained" weight loss that is not brought on by a decrease in caloric intake or physical activity. Cachexia may be a sign of a significant medical condition. Slimming is a term used frequently to describe intentional weight loss.
