Weight reduction

The process of losing excess body fat. A person who is severely overweight (see obesity) is more at risk of various illnesses, such as diabetes mellitus, hypertension (high blood pressure), and heart disease. The most efficient way to lose weight is to eat 500–1,000 kcal (2,100–4,200 kJ) a day less than the body’s total energy requirements. Exercise also forms an extremely important part of a reducing regime, burning excess energy and improving muscle tone. In most circumstances, drugs play little part in a weight loss programme. However, sibutramine and orlistat may be useful adjuncts to a reducing diet and may be appropriate for some people with a high BMI (see body mass index). Appetite suppressants related to amfetamines are not recommended.
