NICE quality standards describe high-priority areas for quality improvement in a defined care or service area. Each standard consists of a prioritised set of specific, concise and measurable statements. They draw on existing guidance, which provides an underpinning, comprehensive set of recommendations, and are designed to support the measurement of improvement.

This quality standard covers ways of preventing adults (aged 18 and over) becoming overweight or obese and the provision of lifestyle weight management programmes for adults who are overweight or obese. Although local definitions vary, these programmes are usually tier 2 interventions covering lifestyle interventions that may include weight management programmes, courses or clubs, and form one part of a comprehensive approach to preventing and treating obesity.

This quality standard does not cover specialist management (tier 3 interventions) or bariatric surgery (tier 4 intervention). For more information see the obesity: prevention and management in adults topic overview.

NICE quality standards focus on aspects of health and social care that are commissioned locally. Areas of national policy, such as legislative changes and marketing of calorific drink and food products, are therefore not covered by this quality standard.
