I'm not an expert like many such as Karen and Doreen but my personal experience is that it is my downfall! I kept trying as I just love our wonderful New Zealand wine. Even with factoring in the carbs it stalled me. Not because of the alcohol itself but because I couldn't make myself just have one glass and I then lost my impetus. I think if you can stick at one and factor it in to the carb allowance it would be fine. It isn't a carb but it has to be counted like as one because your body will use it for energy before it uses fat. Maybe give it a try and see what happens?
