Researchers say the United Nations' aim of halting the rise of obesity across the world is on track to failure.
At the current rate, experts believe a billion people will be classed as obese within 10 years.
And it is not just a problem for those living in wealthy nations. Many developing countries are also experiencing a rapid rise in obesity.
The diseases obesity creates kill about three million people every year, and one assessment has found that the cost on the global economy is $2 trillion a year.
Leading scientists say tackling the issue goes beyond a simple change in diet.
So who can halt the rise in obesity?
