Single women on weight-loss drugs were 29% more likely to marry within three years
Jobless women were 27% more likely to find work, while men saw little change beyond weight loss.
Noahpinion · Roundup #84: Bears on bikesSingle women who started taking GLP-1 weight-loss drugs were 29% more likely to marry or move in with a partner over the next three years than similar women who did not.
The estimate comes from Rebecca Diamond, whom economist Noah Smith called "one of the most serious and respected empirical microeconomists in the business." She compared people who started the drugs with people who said they wanted them but did not take them, and with people who started them a bit later.
Jobless women who took the drugs were 27% more likely to get jobs over the same three years. Men showed little change apart from losing weight.
One caution remains. Those who take the drugs may simply be more purposeful, more motivated, or otherwise different from those who wait, which could explain part of the advantage.
Questions people ask
What do GLP-1 drugs actually do?
GLP-1 drugs mimic a gut hormone that reduces appetite and slows digestion, helping people eat less and lose substantial weight. The first versions were developed for diabetes, and newer versions were approved for weight management. Common examples include semaglutide and tirzepatide.
Does this prove the drugs cause marriage and hiring?
No. The study compares users with people who wanted the drugs but did not take them, and with later users, but people who seek treatment may already be more motivated or purposeful. Researchers say stronger proof would come from a natural experiment, such as a policy that changes access at different times in different places.
Why would weight loss affect marriage and jobs?
Weight discrimination is well documented in dating and hiring, especially for women, and prior studies link weight loss to higher wages and more callbacks. That pattern makes large social effects plausible, but it does not tell us how much comes from other people's reactions versus greater confidence, energy, or job search.
