Citerank: (21) 348675Adopt a whole systems approach to obesityTackling obesity effectively—accomplishing a population wide-shift—requires a comprehensive and integrated whole systems approach, involving a range of measures focusing on individuals, social and other systems, including at the local and community level, and on the interrelated physical, physiological, social and cognitive factors that determine health outcomes.565CA4D9, 348693Stakeholders – Groups & ActionsExplore the map via the different stakeholder groups and the measures each group can take to help tackle the obesity crisis.58D3ABAB, 348702Individuals and FamiliesThe actions and choices of individuals and families are fundamental to the challenge of tackling obesity. 84E4A378, 348703Actions – Industry2794CAE1, 348780Causes of obesityUnderstanding the causes of obesity is critical to the success of prevention and treatment strategies. However, while (simply put) obesity occurs when energy intake from food and drink consumption is greater than energy expenditure through the body’s metabolism and physical activity over a prolonged period (resulting in the accumulation of excess body fat), in reality many complex behavioural and societal factors contribute systemically to the current crisis and no single influence dominates.555CD992, 352281Changes required across many different policy areasObesity has to be seen as not just a technical, food, physical activity or healthcare problem but a challenge for what sort of society is being built. Small, incremental, publicity-driven (i.e. social market-based) changes might suit the existing balance of policy interests, but a more extensive, co-ordinated, cross-sectoral action would be more effective.1198CE71, 352314Actions – Central Government2794CAE1, 352387Previous physical activities replaced by industrially generated energyIndustrial development allows many different aspects of life that previously involved daily physical activity to be accomplished through industrially generated energy instead; for example, the substitution of motorised transport for walking and cycling, a shift from manual and agricultural work towards office work, and a multitude of labour saving devices at work and in the home.555CD992, 352388Advertising and marketing reinforce new eating patterns Marketing and advertising instil and reinforce new cultural norms about what (e.g. fast food) and how to eat (e.g. snacking), and how much (e.g. larger portions) to eat.555CD992, 352389Reluctance to talk about and address implications of own weightThe weight of the population continues to rise despite media imagery of thin models encouraging a slim ideal that is far out of reach for most of the public.

This paper examines the speed of change in diet, activity, and obesity in the developing world, and notes potential exacerbating biological relationships that contribute to differences in rates of change.

The present report has been written to focus attention on the issue and to urge policy-makers to consider taking action before it is too late. Specifically, the report:

• reviews the measurement of obesity in young people and the need to agree on standardized methods for assessing children and adolescents, and to compare populations and monitor trends;

• reviews the global and regional trends in childhood obesity and overweight and the implications of these trends for understanding the factors that underlie childhood obesity;

• notes the increased risk of health problems that obese children and adolescents are likely to experience and examines the associated costs;

• considers the treatment and management options and their effectiveness for controlling childhood obesity;

• emphasizes the need for prevention as the only feasible solution for developed and developing countries alike.
