You’ve probably heard that alcohol contains empty
calories and, if you want to lose weight, it’s a good idea to scale back on how
much you drink. But there’s a difference between hearing your friend’s cousin
lost a bunch of weight after she stopped drinking beer and knowing the actual
science around weight and alcohol.
According to a
new study published in the American
Journal of Preventative Medicine, people who drink heavily when
they’re younger have a higher risk of gaining excess weight and becoming
overweight or obese when they’re older. For the study, researchers analyzed
data from the U.S. National Longitudinal Study of Adolescent to Adult Health
from people when they were in their late teens and early twenties and again
when they were in their mid- to late-twenties and early thirties.
People who
were heavy drinkers (which is defined by the Dietary Guidelines for
Americans as having four or more drinks on any day or eight or more drinks
per week for women) had a 41 percent higher risk of going from a normal weight
BMI to an overweight BMI when compared with people who weren’t heavy drinkers,
and a 36 percent higher risk of going from an overweight BMI to an obese BMI by
the time they hit their mid-twenties. If someone was already obese, they had a
35 percent higher risk of staying that way and gaining more weight.
