Loneliness Can Lead to Food Cravings, But Healthy Foods Can Provide Satisfying Comfort

Understanding healthy ways to deal with loneliness is just as important for your health as diet or exercise. A recently published study in Nature Neuroscience found that when people socially isolate the mid-brain regions are activated in a similar way that they do after fasting. The researchers concluded that social isolation causes social craving, similar to the way fasting causes hunger. The 40 participants, 18-40 years old, surrendered their cell phones and laptops to the researchers before spending 10 hours alone in a windowless room without email or social media access. They were able to play puzzles and computer games. Being in a windowless room for that long was probably more extreme than what most of us are experiencing as we socially distance. But what can we learn from this?

 According to Rebecca Saxe, the lead author of the study, even though most of the participants had satisfying social interactions their isolation had a big effect on their brains. It made them crave food, even if they had food in the room. On a different day, the participants fasted for 10 hours. After the 10 hours of isolation or fasting, the participants’ brains were scanned while looking at images of food, images of people interacting, and neutral images such as flowers. The researchers focused on a structure in the middle of the brain called the substantia nigra. It gave a similar “craving signal” when the participants saw the images of food and people socializing. Chronic loneliness is known to have a harsher effect on older people and adolescents, and the researchers are interested in discovering how isolation affects different age groups.

What Can You Do?

For now, it’s helpful to know that social isolation affects us in a way similar to craving food. It’s a good reminder about the importance of staying connected, as well as being mindful about what we eat and to not unconsciously reach for a bag of chips to satisfy our loneliness. Many of us have spent lots of time on Zoom this year. If you are lonely or have loved ones who are isolated here are some ways to socially engage without leaving your house.
