A recent study examined brain scans of women who looked at abstract images unrelated to food or images of sweet and savory foods. The women who felt the most lonely and socially isolated had the highest level of brain activity in the regions connected to sugary foods and cravings. At the close of the study, study authors concluded that building social connections may cause people to eat healthier.
This new research, published by JAMA Network Open, builds on previous investigations linking loneliness to poor mental health. Earlier studies also linked loneliness to cognitive decline, weight gain, and obesity-related conditions, such as type 2 diabetes. Although there is a lot of evidence for these connections, researchers still don’t have a clear idea of the underlying causes. For example, obesity is linked to depression and anxiety, and binge-eating is common coping mechanism for loneliness.
The Study
Study authors surveyed 93 women about their social connections, body weight, feelings of loneliness, and eating behaviors. Scientists then used MRI scans to see how their brains responded when they looked at abstract images unrelated to food or images of different sweet and savory foods. Overall, participants who reported higher levels of loneliness or isolation were more likely to have sugary cravings. The loneliest participants also experienced reduced brain activity in regions responsible for self-control related to eating behaviors.
Loneliness or social isolation can cause food cravings similar to the cravings you have for social connections. Study authors found that social bonds are integral to how people eat unhealthy foods, especially foods high in calories and sugar.
Study Suggests New Ways To Reduce Sugar Cravings
Although the study linked loneliness to increased sugar cravings, the study had certain limitations. Two of the limitations were the small size and the reliance on participants to accurately report details about the mood, eating behaviors, and overall health. That said, the study provides new evidence that supports the link between your mood and response to food.
Additionally, the study found that the participants’ brains were particularly reactive to sweet foods. Researchers note that this explains the maladaptive eating behavioral changes among socially isolated people. The good news is that finding out this information can help socially isolated people make positive changes in their social lives, which can alter their eating habits. One of the best ways to start is to find ways to build social support systems. Some examples include volunteering, joining clubs, playing sports, or pursuing a new hobby. Anything that increases your interactions with other people can be beneficial, and may help change how your brain responds to food cues.
When you are aware that sugar cravings are connected to loneliness or social isolation, you can feel empowered because you have the ability to change your eating patterns. Understanding that loneliness causes you to crave high-calorie, sugary foods is very empowering. You may want to consider holistic mind-body interventions to help correct the way you think about food. Meditation, journaling, deep breathing, and other stress-reduction exercises can be beneficial in changing the way you think about food.
