UK: Abundant rich food, too little exercise and lack of will on the part of policy-makers could swell the number of obese Britons to a staggering 26 million by 2030, according to the latest forecast.

If current trends continue, the size of the clinically obese population in the UK will increase by 11 million over the next two decades, experts predict.

The resulting extra cost burden on health services coping with obesity-linked problems such as heart disease, diabetes and cancer would be �2billion per year. This represents an overall increase in health spending of 2 per cent.
