"But new research suggests that women who regularly consume moderate amounts of alcohol are less likely to gain weight than nondrinkers and are at lower risk for obesity.... Although alcohol is packed with calories (about 150 in a six-ounce glass of wine), the nondrinkers in the study actually gained more weight over time: nine pounds, on average, compared with an average gain of about three pounds among regular moderate drinkers. The risk of becoming overweight was almost 30 percent lower for women who consumed one or two alcohol beverages a day, compared with nondrinkers."
This only applies to women, for some reason. I'm thinking that the urges satisfied by a drink or 2 correspond to the consumption of food. Even if a nice glass of wine is 150 calories, that's a lot less than a bowl of chips or a plate of cookies. Plus wine is sipped. That's slow. It's those foods that trigger wolfing that are going to make you fat.
