Absolutely. Thanks for mentioning it.
Low-carb beer is one of the biggest head-fakes there ever was. Alcohol weighs in at 7 calories per gram, or about 100 calories per shot, glass of wine, or standard 12 oz. cerveza. By the time you've had four drinks you've loaded yourself up with the energetic equivalent of a good-sized meal. Hopefully you're not drinking instead of eating, so you've loaded yourself with an extra good-sized meal. And if you got drunk before you ate, well, when's the last time you had chili fries?
Even if you only had one drink accompanying a well-planned, home-cooked bowl of food, it would still be a hundred extra calories (or more when you count the sugar). The math on this one is easy. It adds up.
The reason I didn't go into it that much in the book is that I didn't want to tell people that they shouldn't have alcohol. While bad for your jellyroll, a drink or two can be good for your heart if you are in otherwise good health.
I'm not looking to take away anyone's fun. In terms of how it affects your fat, alcohol should be treated like anything else that is nothing but calories: Sometimes you say Fuchet, sometimes you don't. If you can't get it under control, fat ankles will be the least of your problems.
