Today, more than one in two adults and nearly one in six children are overweight or obese in the OECD area. The obesity epidemic has spread further in the past five years, although at a slower pace than before. Despite this, new projections show a continuing increase of obesity in all studied countries. Social disparities in obesity persist and have increased in some countries. A nearly tenfold variation in obesity and overweight rates can be seen across OECD countries. In the last few years, new policy strategies devised to fight obesity have emerged. This Obesity Update focuses on a selection of those, specifically at communication policies aimed to tackle obesity, in particular by improving nutrient information displayed on food labels, using social and new media to sensitize the population, or by regulating the marketing of food products. Better communication helps empower people to make healthier choices. However, comprehensive policy packages, including not only communication but also broader regulatory and fiscal policies, are needed to tackle obesity effectively.
