People who make healthy lifestyle choices should be priortised for non-emergency hospital appointments as a reward, a report by think tank Demos recommends.

Released today the report Control Shift said NHS users could prove their responsible lifestyles by sharing data from their supermarket or gym and this would promote a public service culture of "getting back what you put in".

It said the government could top-up benefit recipients' Universal Credit if they attended the gym regularly.

The report said the government could encourage the private sector and online retailers, such as supermarkets, to give shoppers a health tally of their weekly shop, encouraging shoppers to choose fruit and vegetables, remind people of the health risks of buying too much alcohol and saturated fats.

Report author Max Wind-Cowie said: "These proposals are about more than just saving money.

"They are about helping people make informed decisions and take greater personal and collective responsibility - an attitude that has become even more salient now that there is less in the coffers."

Last year a report released by Local Government Information Unit (LGIU) and Westminster Council recommended GPs prescribe patients physical activity at local leisure facilities.
