[Correspondence] Tackling obesity: challenges ahead

The recent Obesity Series published in The Lancet considered the bigger picture of environmental factors. The authors of the Series emphasised and proposed important obesity prevention measures, including changing the environment, stimulating the expression of healthy food preferences, and establishing smart food policies.1,2 Some individual factors play an essential part in the development of obesity and therefore should also be a target for obesity prevention. For example, it is well established that alterations in fetal growth increase the risk for developing obesity and its metabolic consequences later in life.
