Is Restriction Driving Your Obsessive Food Thoughts? What Therapy Reveals

TL;DR

If food is constantly on your mind and you’re struggling to focus on anything else, the cause may be simpler than you think. You’re likely not eating enough. Restriction triggers a primal survival response that redirects the brain’s attention toward food. It can lead to obsessive thoughts, irritability, and difficulty concentrating. These are predictable and unavoidable consequences of not meeting the body’s basic needs.

Sleep deprivation makes rest impossible to stop thinking about. Likewise, chronic dieting hijacks cognitive function in the same way, regardless of body size. Research confirms that dieters experience measurable cognitive deficits as a direct result of food preoccupation. The solution isn’t more discipline or a better diet strategy. It’s eating more consistently and adequately. If obsessive food thoughts are interfering with your daily life, eating disorder therapy can help. You can begin to understand what’s driving the thoughts and build a path toward genuine relief.

Restriction May Cause Obsessive Food Thoughts

If you find that you are thinking about food all day, having trouble concentrating, or even having trouble sleeping, the reason might be simpler than you think: You might not be eating enough. As an eating disorder therapist in Los Angeles, I see people who are often surprised to learn that what they think is healthy discipline is often highly disordered eating. Obsessive food thoughts are often a clue that someone is not eating enough.

We live in a culture that tells us we should be restricting our intake and dieting to be our thinnest and most virtuous selves. You may have learned various diet methods to eat less. Several common dieting strategies often come up in eating disorder therapy. These include skipping meals, limiting certain types of foods, counting calories, or restricting the amount of food you eat. You may believe this is healthy. However, our bodies think otherwise and will override most attempts at restriction.

Food was relatively scarce for most of human history (until the last 100 years or less). To survive as a species in this environment, the bodies of our ancestors—those that survived to reproduce and passed on those genes—successfully prioritized eating over other activities. At times when food was less available, our ancestors learned to stock up on food when they could. Bingeing—or eating a lot when food was available after a famine— was not a matter of poor willpower, but a perfectly normal and healthy body response to starvation. Anyone who didn’t “binge” when a rare animal wandered into their territory wouldn’t survive and pass on their genes. Hence, all of us alive today have genes from ancestors who prioritized getting enough food.

What Are the Five Basic Needs of Humans?

According to Maslow’s hierarchy of needs, all mammals, including humans, have five basic needs for survival:

1. 1. food
2. air
3. water
4. warmth
5. sleep

If any one of these basic needs is not met, the mammal will eventually die.

These needs can be temporarily subdued. However, over time, when any one of these needs is not met, the drive to meet that need increases. The longer a basic need goes unmet, the harder it becomes to resist satisfying the need. Consequently, several things predictably happen:

• one’s attention becomes increasingly focused on meeting the need;
• it becomes hard to concentrate on anything else;
• a powerful craving to meet the need is experienced;
• one becomes increasingly irritable and unhappy; and
• when the need is finally met, a larger-than-normal amount is needed to make up for the deprivation.

Why Doesn’t Restricting Food Work?

Here is how I often explain this concept to clients at EDTLA.

Consider what happens when you are sleep-deprived. If you pull several all-nighters in a row, by the end of the week, you are probably irritable and have trouble concentrating. When you finally do sleep, you sleep longer than on a typical night.

Similarly, if you go on a hike and forget your water bottle, towards the end of the hike, you are probably getting frustrated and increasingly focused on getting a drink. Then, when you finally do get to a water source, you probably gulp several ounces all at once versus taking a few dainty sips.

To demonstrate how this relates to food and dieting, Kathy Kater, author of the health curriculum Healthy Bodies: Teaching Kids What They Need to Know, provides a lesson plan in which she encourages students to try an “air diet.” The students are given a drinking straw. Next, they are asked to breathe in and out through the straw, plugging their noses, while listening to a story that is a minute or so long. Typically, the students find it hard to concentrate on the story as the air restriction begins. They become increasingly preoccupied and anxious about getting sufficient air. When they are finally allowed to breathe normally, they gasp, gulp, and take in larger-than-usual amounts of air.

How Dieting Backfires and Causes Obsessive Food Thoughts

When a person diets or doesn’t eat enough for their body’s needs, they usually become preoccupied with eating. They may also start to experience intrusive thoughts about food and experience difficulty concentrating on other things. This is the primal drive trying to ensure survival. When our basic needs are met, preoccupations with that need naturally subside. People on diets may also become increasingly irritable, just like people who are sleep-deprived. This can occur among people of all body sizes. Being in a bigger body does not mean that you don’t need regular daily intake.

In her book Secrets From the Eating Lab, Tracy Mann, Ph.D., reports that laboratory studies confirm that dieters show cognitive deficits. “Focusing extensively on food and eating (and sometimes also concerns about your weight) steals valuable attention from other activities, and the more preoccupying food thoughts dieters have, the more difficulty they experience thinking about other things and handling other cognitive tasks.” Thus, even though chronic dieters may not have a traditional eating disorder, this preoccupation with food may interfere with functioning in a significant way.
