GLP-1–Induced Weight Loss and the Female Obesity Penalty

 GLP-1 medications generate large weight loss and may also alter social and economic outcomes. Using the Understanding America Study, this study compares women starting GLP-1s for weight loss with matched women who would like to start a GLP-1 but have not. 

Single women’s marriage/cohabitation rates rise by 29 percentage points and employment among baseline non-employed women rises 27 percentage points after six or more quarters. 

Existing partnerships do not dissolve, and already-employed women show no upward job mobility. 

The pattern suggests that part of the female obesity penalty operates at new-match formation rather than only through health or incumbent productivity.
