Food and Anxiety: The Vicious Cycle
When I am hungry, I feel nervous. I’m like a squirrel, darting around to find a nut. In the kitchen, when I am impatient to eat what I’m cooking, I get butterflies in my stomach. (There’s an old Joan Rivers joke from back in the day when Elizabeth Taylor was fat and microwave ovens were novel: “She stands in front of the microwave and yells, ‘Hurry up!’”)
I’ve noticed lately that I have conditioned myself, conversely, to eat when I am nervous. Aha! I’m in the habit of responding to nervousness with food–whether or not the nervousness is about hunger. I bet a lot of people do something like this.
So I was interested to read a passage in “Change Your Brain, Change Your Body” by Daniel G. Amen, MD, discussing the brain’s responses to food.
MIT researchers demonstrated that simple carbohydrates, such as cookies or candy, boost seratonin levels. [Seratonin relieves anxiety, depression, and obsessive thinking.]
[Researchers Matthew Gailliot and Roy Baumeister] write that self-control failures are more likely to occur when blood sugar is low. Low blood sugar levels can make you feel hungry, irritable, or anxious–all of which make you likely to make poor choices. Many everyday behaviors can cause dips in blood sugar levels, including … consuming sugary snacks or beverages, which causes an initial spike in blood sugar then a crash about thirty minutes later.
Therefore, anxiety and eating is a vicious cycle. I eat to relieve anxiety. If I happen to eat something sweet, then my blood sugar level crashes. When it does, not only do I crave more sugar (especially if I am still anxious), but I lack the mental self-control to make a healthier choice.
I wonder if this cycle leads to all-or-nothing thinking in dieting: if I eat one cookie, then the diet is blown and I might as well have another, and another.
Being aware of this vicious cycle, and the physiological goings-on that cause it, are helping me see it when it happens and say “Stop already.”
My weakness: the drawer full of Zone Bars (evil disguised as health food) at an office where I work. Stop already.
