Researchers from Hebrew University and Sheba Medical Center have identified a link between social eating and improved metabolic health. The study, published in Science Advances, suggests that consuming meals in the company of loved ones can lead to lower glycemic peaks and faster blood sugar recovery following carbohydrate consumption compared to eating alone. Experts, including Professor Shir Atzil, Monia Masalha, and Dr. Shai Fuchs, have termed this phenomenon ‘social physiology’. They propose that the human body regulates itself more efficiently when social partners are present. Atzil noted that proximity to a loved one may reduce the physical energy the body must expend on self-regulation. The research indicates that these biological benefits extend beyond glucose regulation. Social proximity was also found to improve thermoregulation during cold exposure and reduce stress responses in both adults and infants, even in the absence of physical contact. Further investigation into these metabolic responses has quantified the impact of social environments. A study of 54 couples found that consuming simple carbohydrates, such as white bread, alongside a romantic partner resulted in an average 24% lower total glucose response compared to eating alone. Researchers suggest this may be attributed to ‘social buffering’, a process where the presence of a loved one helps regulate stress, thereby mitigating extreme blood sugar spikes.
