KUALA LUMPUR, Dec 5, 2025 – New research suggests that a loving and emotionally supportive marriage may play a powerful role in protecting against unhealthy eating habits and weight gain. A study conducted by researchers at UCLA Health has found that individuals reporting strong emotional support from their spouses tend to have lower Body Mass Index (BMI) and exhibit fewer food cravings, especially toward high-calorie or addictive foods.
Published in the journal Gut Microbes, the study highlights a growing understanding of how social relationships influence the brain–gut connection, showing that emotional well-being may be more deeply tied to eating behaviour than previously believed. Through brain imaging scans and analysis of gut metabolites, researchers observed that participants in supportive marriages showed healthier activation patterns in brain regions responsible for appetite control when exposed to food cues.
The team identified possible biological links behind the trend, including elevated levels of oxytocin, often referred to as the “love hormone,” which has been associated with improved emotional bonding, stress reduction, and appetite regulation. According to the researchers, oxytocin may help reduce food cravings while supporting positive gut health markers, including metabolic and anti-inflammatory pathways.
Lead researchers say these findings underscore the importance of viewing nutrition and obesity risk through a more holistic lens, one that acknowledges the impact of emotional support, stress, and close relationships. While diet and exercise remain key factors influencing body weight, the study suggests that social harmony at home may offer meaningful protection against overeating and weight gain.
The research opens new avenues for understanding the influence of social environments on health outcomes, marking a shift toward recognising emotional support as a potential tool in improving dietary behaviour and weight management.
