I believe you're referring to a thread I initiated because of questions I got while teaching my weight loss class. I firmly believe that the calories in vs. calories out go when it comes to alcohol just like anything else. If you drink a lot of alcohol, you consume many calories. You will gain weight (or not lose weight). It's no different than asking if it's true that you gain weight if you eat a lot of chocolate (and you will, in case you should be in doubt. lol). Of course, what can severely influence is that lack of judgement often comes with alcohol, and you may drink/eat more than you actually think you do.
Sure, there is a dehydration factor and all that, but IMO this matters absolutely nill. We're not here to lose water. We're here to lose fat. Water will come and go no matter what we do.
