Diets are a hot topic every New Year, but it seems many of us forget to count the calories in alcohol.
New Year dieters often fail to consider how calorific a glass of wine is when planning their January weight loss programme, it's been revealed.
It's an important oversight many of us are making too, as cutting down our alcohol consumption this 2013 could not only help us lose weight, but also reduce our risk of cancer.
Being overweight is currently the second biggest cancer risk factor, after smoking.
To combat this, the World Cancer Research Fund (WCRF) has produced an online alcohol-calorie counter to help slimmers lose weight this New Year.
The counter breaks down how many calories can be found in our favourite tipples into easily understandable comparisons, such as how a pint of lager has the same calorie count as three chocolate biscuits.
Kate Mendoza, head of health information at WCRF, said: "The calories in alcoholic drinks account for a significant proportion of a drinker's calorie consumption while providing little, if any, nutritional benefit.
"Cutting down on drinking can have a big effect on weight loss or maintaining a healthy weight."
She added: "Recent reports have shown that people are unaware of calories in drinks and don't include them when calculating their daily consumption. This is important from a cancer perspective because after smoking, being overweight or obese is the biggest risk factor.
"There is also strong scientific evidence that alcohol itself is a cancer risk factor, possibly through damaging our DNA, in cancers of the breast, bowel, mouth, pharynx, larynx, oesophagus and liver."
