Publisher's Synopsis
In the fields of medicine, health, and physical fitness, weight loss is defined as a mean loss of fluid, body fat (adipose tissue), or lean mass (bone mineral deposits, muscle, tendon, and other connective tissue), which results in a decrease in total body mass. Weight loss can occur either unintentionally as a result of malnutrition or an underlying disease or as a result of a deliberate effort to improve an actual or perceived overweight or obese state. Unexplained" weight reduction that isn't brought about by decrease in calorific admission or exercise is called cachexia and might be a side effect of a serious ailment.
