If current trends continue, the size of the clinically obese population in the United Kingdom will increase by 11 million over the next two decades to a staggering 26 million, a new study predicts.

In the worst case scenario, almost half of adult men in the UK could be obese by 2030. Obesity prevalence among UK men is forecast to rise from 26 per cent to between 41-48 per cent. The proportion of obese women is predicted to increase from 26 per cent to 35 to 43 per cent.

The figures, published in The Lancet medical journal, were produced by an international team which analyse obesity trends in the UK and the US, the countries with the highest obesity levels in the developed world.
