"We say that alcohol is empty calories for a reason; with 80 to 150 calories per drink, these can add up quickly," Kinzly said. Alcohol is also high in sugar, which keeps insulin levels high, which Dr. Fung said can actually prevent your body from using fat stores as energy.
Drinking alcohol can also lower your inhibitions and make it easier for you to say yes to foods you wouldn't normally eat and make it harder for you to listen to your body's "I'm full" signals. So if you want to lose body fat, limiting the wine, beer, and cocktails can make a huge difference.
