Adults with a body mass index (BMI) between 25 and 29.9 kg/m2 are considered overweight. Those with a BMI ≥30 are considered obese. The initial recommendation for any weight loss effort is to achieve a 5-10% reduction in weight, which has been associated with a reduction in the risk of developing type 2 diabetes, hypertension, and dyslipidemia.

The FDA has approved over-the-counter (OTC) sale of the weight-loss drug orlistat (Xenical – Roche)1 as alli (GlaxoSmithKline), to be used in combination with a reduced-calorie, low-fat diet. Orlistat binds to gastric and pancreatic lipases, preventing absorption of about 30% of dietary fat with the 120-mg prescription dose, and 25% with the 60-mg OTC dose. A 16-week controlled trial of the OTC dose (60 mg 3 times daily with meals) in overweight, not obese, patients (average BMI 26.8) on a reduced-calorie, low-fat diet found that patients taking the drug lost 1.15 kg more than those taking...
