The Royal Society for Public Health has said that alcoholic products should carry labels stating their calorie content in order to tackle obesity.

Doctors at the society have said that too many people are unaware of how many calories alcoholic drinks contain.

Alcohol is currently exempt from EU food labelling laws, but the European Commission is considering whether to change the ruling.

The RSPH's chief executive, Shirley Cramer, told the BBC: "(It is) quite startling really - 80% of adults have no idea what the calorie count is in anything they're drinking and if they do think they have an idea they totally underestimate it anyway.

"It could help the nation's waistlines as well as probably reduce alcohol consumption."
