Daily social resources as a buffer against stress eating and its consequences

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.

In Study 1 (N = 1,264), we assessed stress-eating tendencies, body mass index (BMI) and waist-to-hip ratio (WHR) at baseline, receipt of emotional support over 8 days (9,649 reports), and tracked BMI/WHR after about 10 years. We examined the average likelihood of receiving emotional support as a moderator of the link between stress eating and BMI/WHR at the follow-up. In Study 2 (N = 536; 10,288 reports), we assessed stress-eating status and BMI at baseline, social responsiveness (feeling that others are caring), and stress-eating behavior over 24 days and tracked BMI a year later. We examined if social responsiveness moderates stress-eaters' daily stress-eating behaviors and changes in BMI.

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.

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. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
