No country managed to reduce its obesity prevalence between 2000 and 2013. During this period,
prevalence grew by 0.5 percentage points or more a year in 130 of the 196 countries for which the
OECD documents obesity prevalence data (OECD 2014). This was once a problem of relatively
prosperous developed economies but, as incomes rise in the emerging world, the problem is
spreading. Today, around 60% of the world’s obese people are in developing countries.
