Drinking Alcohol Reduces Weight Gain

Women who consumed one or two alcoholic drinks on a daily basis gained less weight during mid-life than did abstainers, according to medical researchers at Brigham and Women's Hospital in Boston.

The investigators studied over 19,000 women aged 38.9 years or older whose weight was initially in the normal range. Information about the diets and lifestyles of the women was recorded for nearly 13 years.

After adjusting for age, baseline weight, smoking, nonalcohol energy intake, physical activity level, and other dietary and lifestyle factors, women who consumed one or two drinks were at least 30% less likely to gain weight over the period of the study.

The inverse relationship between amount of alcohol consumed and weight (that is, the more alcohol consumed, the lower the weight) was also found among subgroups of women based on age, smoking, level of physical activity, and initial weight.

These research findings are consistent with those of earlier investigations on the relationship between drinking alcohol and weight gain or loss.

The authors of this study note that women exhibit a substantial increase in energy expenditure after drinking, suggesting that they might experience a net loss of calories after drinking alcoholic beverages. This may account for the fact that drinkers were much less likely to gain weight.

The moderate consumption of alcohol (beer, wine and liquor or distilled spirits) is also associated with better health and longer life than is either abstaining from alcohol or abusive drinking [learn more about Alcohol and Health].

Standard drinks of beer, wine and distilled spirits contain an equivalent amount of alcohol and have equivalent health benefits. A standard drink refers to:

Although most alcohol beverages contain fewer calories than most non-alcohol beverages, some people are still concerned about gaining weight from consuming them. However, alcohol contains no fat and is very low in carbohydrates. Additionally, it appears that the "effective" calories in alcohol are substantially lower than the numbers listed.

The bottom line is that women who consumed one or two drinks of alcohol each day gained significantly less weight than did alcohol abstainers.
