Also, the researchers pointed out, women tend to substitute alcohol for other foods, whereas men tend to simply add alcohol to everything else they're ingesting.
"The impact of alcohol consumption on body weight needs to be considered in the context of energy balance," Wang explained. "Among women, those who regularly consume light-to-moderate alcohol usually have a lower energy intake from non-alcohol sources. On the other hand, alcohol intake tends to induce increased energy expenditure beyond energy contents of the consumed alcohol in women. Taken together, regular alcohol consumption in light-to-moderate amount may lead to a net energy loss among women."
Marianne Grant, a registered dietitian and health educator at the Texas A&M Health Science Center's Coastal Bend Health Education Center in Corpus Christi, said that "it's possible that women who are of healthy weight are not as efficient in metabolizing alcohol."
"But, as always, the message is to enjoy alcohol in moderation," she warned. "Don't go with this as a weight-loss method. The keystones of healthy nutrition still hold."
The U.S. Centers for Disease Control and Prevention has more on maintaining a healthy weight.
