OBJECTIVE: Eating in response to stress can become habitual and have long-term consequences for weight gain, but little research has explored what may help break stress-eating cycles. We examined daily social resources as potential protective factors against daily stress eating and eventual weight gain. METHOD: In Study 1 ( RESULTS: In Study 1, stress eating predicted increases in BMI and WHR at the 10-year follow-up but not among individuals who were more (vs. less) likely to receive emotional support in daily life. In Study 2, stress eaters tended to report more daily stress-eating behaviors compared to nonstress eaters, but such tendency was attenuated on days they perceived high (vs. low) levels of social responsiveness. Stress eating did not predict BMI at the 1-year follow-up. CONCLUSIONS: These observational findings suggest that social resources in daily lives may have long-term benefits for stress eaters, potentially by reducing their everyday stress eating.
