Obesity is an epidemic accelerating out of control. It is the driving force behind an equally dramatic explosion of Type 2 diabetes, both in adults and now alarmingly among children. Clearly, strategies aimed at improving the prevention and management of obesity must be developed. Not confined to affluent nations, the obesity epidemic imposes a double burden on countries where people are still struggling to overcome generations of chronic undernutrition. Economic progress in developing countries heralds changes in lifestyle. People migrate to the cities, where urban planning stifles opportunities for everyday activity and where fresh foods are scarcer and more expensive. As a result, people tend to eat more fat and sugar and less fresh fruit and vegetables. All of this is conspiring against sustainable health.
