Wine, beer, and booze manufacturers may soon have to put nutrition labels on their bottles and cans.

The U.S. Alcohol and Tobacco Tax and Trade Bureau proposed a labeling rule in 2007 that would require alcoholic beverage manufacturers to include calories, carbohydrates, fat, and protein content on their labels – but didn't move forward with it, keeping the labeling optional.

But as the fight against obesity continues, the government is under more and more pressure to make the labeling mandatory.

The awful truth is that alcohol alone has 7 calories per gram. There's no getting past it – beer buzzes lead to beer bellies.
