14 Milan Declaration calls to action: To address this situation, obesity should become a top priority, with increased commitment for concerted, coordinated and specific actions. A comprehensive, sustainable and pro-active strategy to deal with the challenges posed by the obesity epidemic is urgently needed. Encouraging the development and implementation of programmes for prevention, early diagnosis and treatment is mandatory. It is clearly imperative that obesity, as a disease and as a gateway to NCDs, is targeted as an area for immediate action and priority for research, innovation and action. In 1999 EASO issued a Milan Declaration in which we called for recognition, support and national action in this field. In the intervening years great progress has been made but more needs to be done and we must act now.

15 Milan Declaration Statement I It is clear that weight management must now play a major role in reducing morbidity and mortality of populations in Europe and world-wide. EASO resolves to provide leadership, guidance and support to governments, as part of its mission of facilitating and engaging in actions that reduce the burden of unhealthy excess weight in Europe through prevention and management, but a wider effort is needed. EASO therefore calls on governments, health agencies and all relevant stakeholders to: Recognise that individuals and communities who are obese require understanding, respect and support.

16 Milan Declaration Statement III Prioritise obesity as a national health action, by developing, supporting and implementing national strategies for action on obesity. These strategies must prioritise medical education (undergraduate and HCPs) and public information campaigns. Prioritise the identification of critical unmet needs in obesity research, clinical care, education and training and other areas that have yet to be adequately addressed. Support national and European research that will inform and develop new and effective prevention and management strategies, thus delivering real societal benefit.
