A Practical Perspective on Confronting the Obesity Epidemic: Public-Health Strategies

Obesity is currently recognized as a global epidemic and contributes to numerous health complications. It is strongly associated with poor dietary habits, including the widespread availability and consumption of high-calorie foods. We conducted a narrative review of publications from major biomedical databases addressing obesity treatment and public-health interventions. One of the strategies for managing obesity is lifestyle modification-balanced diet and regular physical activity-supported by pharmacological and psychological treatment, and, in selected patients, metabolic and bariatric surgery. Beyond patient-level care, public-health-oriented measures should be considered, including taxation of sugar-sweetened beverages, restriction on advertising of unhealthy foods, regulation of the school food environment, front-of-pack nutrition labelling, mandatory food reformulation, subsidies and incentives for healthy foods, urban-planning policies that promote physical activity, and policies that expand access to bariatric surgery. A comprehensive approach integrating clinical care with public-health policy is likely to yield more effective outcomes than either alone.
