Contrary to popular belief, a new study from the University of Virginia has found that relationship conflicts may lead to a decrease in snacking behavior, rather than emotional overeating. The research sheds light on the complex relationship between interpersonal stress and eating habits, challenging existing assumptions. This blog post explores the surprising findings and their implications for long-term health. Eating behavior and interpersonal relationships are closely intertwined, and this study offers a unique perspective on their dynamic.

Strategies to Address Stress within a Relationships Which Impacts Snack Habits
Jennifer MacCormack, one of the researchers behind the study and an assistant professor of social psychology at the University of Virginia, said the idea that romantic conflicts lead to emotional overeating is based on a common assumption. The researchers analyzed 14-day diaries kept by 100 couples and found that people snacked less when partners were particularly unsupportive or untrustworthy.
‘As relationship conflict increases in your relationship dynamics or as something bad is happening in your relationship, people will dip on their snacking behavior temporarily,’ MacCormack, who directs the Virginia effect & Interoception Laboratory explained. Surprised us because other research ties stressful relationships to inappropriate eating and chronic disease.
Snacking: A Symptom of Emotional Changes
This habit instead hones in on snacking behavior because it has the potential to cause fuel consumption that goes above and beyond what one otherwise would have consumed when eating at a set time of day. These emotional shifts in our relationships may show up in our snacking behavior, which MacCormack predicts is “likely to be very affected. This unique data — couples’ daily diaries — allowed researchers to measure how relationship dynamics play out in real-time eating habits.
Still, this trend did not apply to people who were already susceptible to eating for emotional reasons, the investigators said. Relationship stress could simply often lead to more snacking as a sort of coping outlet for these people.

The results of this study have major implications for understanding the nuanced link between relationships and health. MacCormack said, “I think it is worthwhile to note that when we are considering the diet of a person and their metabolic health, people do not live in a vacuum.” “Importantly, these relationships do impact the dynamics of their eating behaviors.
The study illuminates the complex dynamic between relationship stress and snacking behaviors, shedding light on important implications for health and mental health practitioners as well as people looking to feel better. The identification of contextual factors that might affect eating behaviors is crucial in identifying ways to intervene and offer support that could result in greater health benefits over the long term.
