So Much for Love Handles!
The idea of “happy weight” suggests that couples who enjoy time together, perhaps binge-watching Netflix and sharing ice cream, may feel more content rather than hitting the gym. However, recent research from UCLA indicates that a high-quality marriage might actually help guard against obesity. Strong emotional bonds can be just as crucial for physical health as diet and exercise.
“For years, we’ve known that social relationships impact health outcomes, with supportive connections enhancing survival rates significantly,” remarked the study’s lead author, Alpana Church, a neuroscientist at UCLA Health.
“The exact biological mechanisms behind this link aren’t fully understood,” she added. “Our findings shed light on how marriage and emotional support can influence obesity risk in ways that literally go ‘under the skin.’
The study involved nearly 100 individuals from the Los Angeles area, examining everything from Body Mass Index (BMI) and eating habits to brain imaging, hormone levels, emotional support, and even aspects of gut health.
Researchers found that married individuals with strong emotional support had lower BMI levels and fewer signs of food addiction compared to those in less nurturing marriages. Interestingly, when shown food images, those in unhappy marriages exhibited increased activity in the dorsolateral prefrontal cortex, a brain region responsible for controlling cravings.
In contrast, singles and those who have never been married, regardless of social support levels, did not display comparable brain activity patterns.
A complex communication system between the brain and gut seems to play a vital role. Happier spouses experienced positive changes in tryptophan metabolites generated in the gut, which help regulate inflammation, metabolism, immune responses, and neurological functioning.
One noteworthy metabolite is serotonin, a hormone that influences mood, sleep, and appetite. Engaged individuals showed higher levels of oxytocin compared to single individuals, which is known as the “love hormone.” It can help alleviate stress and lower blood pressure, while also potentially speeding up the healing process.
Church suggested that oxytocin could boost brain areas responsible for self-control and promote gut health.
“Consider oxytocin as a conductor orchestrating the relationship between your brain and gut,” Church said.
“It enhances the brain’s capacity to resist food cravings while facilitating beneficial metabolic processes in the gut—both factors essential for maintaining a healthy weight.”
In simpler terms, a supportive partnership may lead to improved self-control, better metabolism, and elevated oxytocin levels.
“Marriage can act as a training ground for self-regulation,” Church explained. “Maintaining a long-term relationship requires continual attempts to overcome impulsive behaviors and align with broader life goals. This could strengthen the same brain circuits that play a role in managing eating habits.”
Church noted some limitations of the study, which was published in the journal Intestinal Microorganisms. Most participants were either overweight or obese, and data was only collected at a single point in time.
Regardless, fostering “long-term, positive, and stable” relationships is crucial for better health. Previous research has indicated that strong social connections may even lower the risk of dementia.
If you’re concerned about your waistline, perhaps it’s time to relax with some Netflix and a scoop of ice cream?
