• Weight loss is achieved by reducing energy intake and increasing physical activity.
• Crash diets do not work in the long-term as changes to lifestyle are not made.
• Obesity is associated with decreased life expectancy, development of type-2 diabetes and an increased risk of cardiovascular disease, certain types of cancer, gallstones and osteoarthritis.
• Some medical conditions and some medicines can cause weight gain.
• There is no published scientific evidence to support the efficacy of herbal or food supplements in weight loss.
• There are published Cochrane reviews, systematic reviews and meta-analyses which demonstrate the efficacy of orlistat in producing modest weight loss in overweight and obese patients.
• Orlistat products, being licensed medicinal products, have been assessed for quality, safety and efficacy as part of the licensing process.
