How hungry are you right now? Were you already thinking about it before I asked you? Now that I mention it, are you hungrier than you were a minute ago? Have you ever felt hungry just a couple of hours after eating a good sized meal and wondered how you could be hungry again so soon? Have you ever gone longer than usual without eating and noticed a mysterious absence of hunger?
Hunger feels a little bit different to everyone—and the same person may experience hunger in different ways at different times. Laurel recently wrote to me about this:
“Sometimes my stomach will growl, but I don't 'feel' hungry. Other times I'll get that weak, shaky, low blood sugar feeling without ever feeling stomach pangs. Then, there is the classic empty stomach feeling, an almost-but-not-quite pain. And sometimes I have an overwhelming desire to eat without bodily sensations. Is there any research on what these different types of hunger mean?”
Hunger is a very interesting thing—it’s equal parts biological instinct and learned response. It can show up as a variety of physical sensations but hunger also has psychological and even emotional dimensions—and these are particularly susceptible to manipulation and cultural influence.
For example, most people used to regularly go four or five or even six hours between meals without thinking twice about it. It’s not that they never felt any sensation of hunger during those hours. It’s just that those sensations weren’t perceived as an emergency.
But then, this popular myth arose that if you went more than two hours without eating, your metabolism would slow down. There was absolutely no truth to this but a lot of people bought into it. And as a result, a random twinge suddenly took on new meaning: “Stop everything! My metabolism is shutting down!”

After a while it gets harder and harder to distinguish physical hunger from anxiety, habit, or plain suggestibility.
As I wrote in a recent newsletter, a central tent of the intuitive eating movement is to listen to our bodies. The idea is to eat when we're actually hungry as opposed to eating simply because it's a certain time or day or because there happens to be food in front of us or because we're feeling bored or blue.
It's good advice … except that our experience of hunger may not always a very reliable guide as to whether our bodies actually need food or not. And we all know what happens if we eat more food than our bodies need.
One sign that your body needs foods is low blood sugar. And, sure enough, when your blood glucose is low, this triggers hormonal signals that increase your appetite and your desire for food. So you'd think that the degree of hunger a person feels would be closely tied to their blood sugar levels. The lower their blood sugar got, the hungrier they’d feel. And yet this isn’t always the case.
Experiments have shown that we can take people who aren’t hungry and make them hungry simply by showing them a movie about food. (And don’t think advertisers aren’t all over that!) Similarly, we can make people who are hungry because they haven’t eaten in a long time feel less hungry by showing them an engrossing film that’s not about food.
People’s reported level of hunger also changes depending on what they are being offered to eat. If it’s really yummy, they feel hungrier. If it’s not that appealing, they’re actually not that hungry. Clearly, simply “listening to our bodies” might not be a foolproof method of knowing whether or not we really need to eat.
I’m not suggesting that you ignore authentic hunger signals or starve yourself. Allowing yourself to get overly hungry can not only feel gross, it can lead to poor food choices. And if you are diabetic, it’s obviously very important not to let your blood sugar get too high or too low. Let your blood sugar monitor be your guide.
What I am suggesting is that feeling a twinge of hunger may not be the emergency that we’ve somehow convinced ourselves that it is. We can afford to take a few minutes to evaluate the physical, psychological, and emotional realities before reacting. You can learn a lot this way, and I believe it can help you honor your hunger more effectively.
