Obesity is a major public health issue. It is common and a strong risk factor for many medical conditions, including Type 2 diabetes mellitus, heart disease, and cancer. Obesity results from an energy intake that exceeds energy expenditure. Cheap, readily available, energy-dense food and sugary drinks together with a sedentary lifestyle are fuelling the rise in obesity. There is growing evidence that interventions to aid weight loss are effective in reducing the risk to health associated with being obese, especially if they combine change in both diet and physical activity. There is only a limited role for drug treatment of obesity in routine care. For individuals at the highest risk of comorbid conditions, bariatric surgery is an appropriate option.
