The effect of stress on overeating.

Lenny Vartanian, PhD., from the Psychology Department of the University of New South Wales in Australia and her colleagues recently analyzed the effect of stress on overeating by placing Cookies in a cluttered/clean kitchen and watching the results. According to a study involving 101 women at Cornell’s food and Brand Lab, researchers showed that when those with heightened stress levels were placed in a noisy, messy kitchen — think scattered newspapers, a stacked sink of dirty dishes, relentless telephone ringing — and they were asked to wait patiently for another person, they ate more. In fact, these women ate twice as many of the cookies left out for them as did their equally-stressed counterparts, who waited in the same kitchen, but one which was organized and quiet.

Environmental chaos can induce stress. Stress then leads to a coping mechanism. In this instance, the coping mechanism was to overeat. And overeating? It’s your one-way ticket to weight gain.

But what’s also worth considering are the cascade of events that led to the overeating — a cascade not relegated to just this one experiment, but one that’s applicable to the broader population. A better understanding of this could help with the diet-and-food-related issues many of us face.

Stress is a condition characterized by symptoms of physical or emotional tension and anxiety. In a normal, stress-free state, we have hormones that circulate our body, catecholamines, called epinephrine and norepinephrine. These hormones give us the energy to perform daily tasks in a calm, consistent manner. But if we’re triggered by an unpleasant feeling or event, these catecholamine levels rise. And our bodies’ natural response is to find a way to lessen them.

One coping mechanism in dealing with stress is to overeat. Eating increases another of the body’s “feel good” hormone, called serotonin, which helps to improve mood. Serotonin tempers the catecholamines, thus reducing feelings of stress.
