The study explains that positive communication and mutual support between spouses leave a significant biological impact, affecting appetite, mood, digestive functions, and metabolic processes in the body. Research conducted at UCLA shows that receiving strong emotional support is linked to increased secretion of the hormone oxytocin, which is considered a link between the brain and the gut.
Effects of Supportive Relationships
Researchers explain that couples who enjoy supportive relationships have stable weight and less impulsive eating behaviors, compared to unmarried individuals or those lacking strong social support. Oxytocin enhances the brain’s ability to resist cravings and strengthens the activity of the prefrontal cortex, which is responsible for decision-making and behavioral control.
In addition, researchers observed clear changes in the gut microbiome of people who have strong emotional support, with increased levels of beneficial compounds associated with tryptophan, such as indole compounds, which contribute to reducing inflammation, improving mood, and regulating energy levels. The results indicate that these compounds are associated with a more balanced intestinal environment and a greater ability to cope with metabolic stress.
The study confirms that oxytocin plays the role of “orchestra conductor” between the brain and the gut, enhancing neural control over eating behavior and simultaneously stimulating beneficial processes within the gut that support maintaining a healthy weight.
Research concludes that emotional support is not just a psychological element but an integrated biological pathway that connects social bonds, brain activity, gut balance, and weight regulation. Stable and supportive relationships, including daily moments of warmth and reassurance, create internal harmony that improves overall health in the long term.
