Symposium 1: Overnutrition: consequences and solutions Foresight Report: the obesity challenge ahead: Conference on ‘Over- and undernutrition: challenges and approaches’

Successfully tackling obesity is a long-term commitment. Current levels of obesity in the population have been ≥30 years in the making. Not only will this position take time to reverse but there will be a considerable time lag before health and economic benefits are achieved through reductions in the morbidity from obesity-related diseases. There is clear evidence that policies aimed only at individuals will be inadequate and that increasing small-scale interventions will not suffice. Major action to prevent excess weight gain at a population level is required. The Foresight Report has confirmed that a ‘whole system’ approach is critical. This approach will require a broad portfolio of integrated policy responses including both national and local measures. This strategy requires action by government, both central and local, industry and communities and by families and the societies in which they live.
