DH and I are on a diet and I have noticed that the number of calories is not listed on wine or beer. Having done a bit of research online I am amazed at how high this can be and how easy it is to consume so many extra calories without realising. Personally I find this more of a deterrent than the recommended units thing and I am amazed that these labels appear on everything but alcohol.
Sorry for being a killjoy so close to the weekend
