A third of Brits want to cut back on alcohol to lose weight, according to a new study.

Yet, government-funded health website Change4Life, who conducted the survey, admit it can be difficult to keep track of all those hidden calories.

Helpfully, the site has released a free online tool, which not only helps you keep track of what you drink, but also tots up the calories too.

Even drinking slightly more than the lower risk guidelines (not regularly drinking more than 2-3 units per day for women, and 3-4 for men) by having either two standard 175ml glasses of wine, or two pints of beer or cider, really adds up.

Two glasses of wine three nights a week clocks in at over 750 calories a week – that’s over a third of a woman’s daily calorie amount – and it could cost you around £18 too.

So if you want to get trim and save some cash in time for Christmas, why not think about cutting back on the booze?

To find out how much you’re drinking in units, cash and calories, give the drinks checker a go and find tips on cutting back, search Change4Life online.
