50% adults overweight or obese by 2050: Global study

What's described as one of the most comprehensive global studies of the rise in unhealthy weights, published in the journal The Lancet, makes for grim reading.

The proportion of people who are overweight or obese has more than doubled in the past 30 years, but it's predicted that by 2050, this will include well over half of all adults and a third of children and adolescents.

Obesity rates are surging right now. By the end of the decade, more people are forecast to be classed as obese than overweight. The picture is wildly uneven across the globe, with some of the biggest increases seen in lower- and middle-income countries.

But the study doesn't take into account the impact that new weight loss medications might have. And experts say if governments take urgent action now, there's still time to prevent what they describe as "a profound tragedy".
