“To lose weight while still drinking alcohol occasionally, begin by making a 'Better Bad Choice,'” Blanchette says. “Consider reducing the frequency that you drink, or cut back on the amount you normally would drink.” If you normally have a glass of wine every night with dinner, consider only having a glass on the weekends. “Let's say you normally have two glasses of wine every night,” she adds. “After one week, that would be a total of 1,700 calories, causing about one pound of body fat to be added every two weeks.”
