There has been a dramatic increase in the numbers of overweight or obese people in the past 30 years. Previously considered a problem in richer countries, the biggest rises are in middle income countries and the developing world.

The ODI report, ‘Future Diets’, traces how the changes in diet – more fat, more meat, more sugar and bigger portions – have led to a looming health crisis.  It also looks at how policy-makers have tried to curb our eating excesses – with mixed results.

The report is launched on 10 January 2014 in London.
