Weight loss, in medical terms, is the reduction of one’s total body weight. Losing weight, coupled with a balanced diet, is the effective cure to obesity. There are two kinds of weight loss: the unintentional and intentional weight loss. Intentional weight loss is a conscious effort to lose weight. A healthy means of intentional weight loss involves a balanced diet and regular exercise. Meanwhile, unintentional weight loss is an unconscious means of losing weight. This occurs mostly as a result of sickness or physical complications.
