When we talk about binge eating and overeating, restriction is one of the most common explanations we use. In intuitive eating and non-diet spaces, we often talk about the connection between restriction and binge eating because research and clinical experience consistently show that trying to limit food can increase preoccupation with food, intensify cravings, and contribute to cycles of overeating.

What Food Restriction Really Means

However, restriction in my experience is often misunderstood. Most people hear the word restriction and immediately think about one thing: eating less. Maybe you imagine skipping meals, eating tiny portions, counting calories, or eliminating certain foods. And while those experiences absolutely can be forms of restriction, they are only one piece of a much bigger picture. This is where many people feel confused when they first learn about intuitive eating or binge eating recovery.

They might say, “I don’t understand how restriction applies to me. Sarah, I eat too much. I overeat. Sometimes I binge. I’m clearly not restricting.” From their perspective, this makes complete sense. If you are regularly eating past fullness, feeling out of control around certain foods, or struggling with binge eating, it can feel almost impossible to imagine that restriction could be part of the picture.

But underneath many struggles with overeating is not a desire to have too much. It is often a response to scarcity. Sometimes that scarcity is truly physical; the body is not receiving enough nourishment. But sometimes it is psychological. Food feels controlled, forbidden, or loaded with judgment. It can also be emotional, where food becomes the only available way to cope with feelings that feel too overwhelming. And sometimes, the restriction happens at the level of the nervous system itself, where the body is searching for safety and regulation.

Food Restriction Isn’t Just Physical

Food restriction is not always about what is on your plate. It can also exist in your thoughts, your emotions, your beliefs, and your relationship with your own body. This is why two people can eat the exact same amount of food and have completely different experiences. One person may feel satisfied and move on with their day. Another person may feel intense urgency, preoccupation, or a need to keep eating.

In my work as a therapist and certified intuitive eating counsellor, I find it helpful to look at restriction through four different lenses: physical restriction, mental restriction, emotional restriction, and nervous system restriction. These categories are not meant to diagnose or put people into boxes. Most people experience a combination of these forms of restriction at different times. Understanding the different ways restriction can show up simply gives us more language and compassion for what is happening.

Because when we understand the function of a behaviour, we can begin to respond differently. Instead of asking, “Why can’t I control myself around food?” We can begin asking, “What is my body or nervous system trying to protect me from?” That question creates a very different starting point for healing.

Physical Food Restriction: When Your Body Is Not Getting Enough

Physical food restriction is the most commonly understood form of restriction. It refers to eating less food than your body needs to feel adequately nourished, energized, and stable. This can look like skipping meals, trying to stay under a calorie goal, intentionally reducing portions, avoiding certain food groups, or attempting to maintain a body size that requires ongoing effort and deprivation.

For many people, physical restriction eventually creates a predictable biological response. The body increases hunger signals, food becomes more mentally consuming, and cravings become stronger. The desire to eat ultimately becomes harder to ignore.

This is not your body failing. It is your body doing exactly what it was designed to do. Your body does not know that a smaller body might be socially rewarded. It does not know that you have a vacation coming up or that you want to fit into a certain size of clothing. It knows that it requires adequate energy to function. When your body senses that resources are limited, it adapts.

Physical Restriction Doesn’t Always Look the Way We Think It Should

The challenge is that physical restriction does not always look the way we expect it to. Many people assume physical restriction only applies to someone who is visibly eating very little. They imagine someone skipping meals all day or surviving on a handful of foods. But folks are often physically restricting without realizing it.

They may be eating breakfast, lunch, and dinner. They could even be including protein, vegetables, and carbohydrates. Maybe they even feel like they are eating in a way that would be considered “healthy” or “balanced” by mainstream nutrition standards. The missing piece is whether that amount of food actually matches what their individual body needs, and this distinction is incredibly important.

Sneaky Physical Restriction

There is a cultural idea that there is one correct amount of food (say 2000 calories) that everyone should need. We often hear numbers, portions, or meal templates presented as if they apply universally. But bodies are not standardized and needs are influenced by genetics, metabolism, activity level, hormones, stress, health conditions, life stage, and countless other factors. Sometimes people are not eating too little compared to a chart or a guideline, but they are eating too little compared to their own body.

This was something I personally had to understand in my own healing. For a long time, I believed my body was supposed to be smaller than it naturally wanted to be. I had internalized the idea that my appetite was the problem and that my body was asking for more than it should. Eventually, I learned that I was not failing to control my body. I was consistently trying to provide my body with less than it needed. I was feeding an imaginary average rather than responding to my actual physiology.

The Problem with Portion Control

This is why portion control can sometimes keep people stuck in binge eating cycles. Someone may technically allow themselves to eat a food, but the amount is still being dictated by an external rule rather than their body’s needs. “I can have this, but only this much.” Or “I can eat dessert, but only a small portion.” While on the surface, this may look like flexibility, internally, the body may still be receiving the message that food is limited.

This is also why comparing yourself to other people is rarely helpful. Your friend skips breakfast and feels fine. Maybe someone you know eats smaller portions and does not struggle with binge eating. Maybe someone else seems to maintain a certain body size with ease. That information does not tell you what your body needs. We cannot see someone’s full history with food, their genetics, their stress levels, their relationship with their body, or what happens privately.

Your body is not failing because it responds differently than someone else’s. If your body is consistently asking for more food, that information matters. Hunger is not a conspiracy. Your body communicating its needs is not something that needs to be overridden. It is information that deserves curiosity. And this is where physical restriction is only one piece of the puzzle. Why? Because many people who struggle with binge eating are not only restricting what they eat.

They are also restricting themselves through their thoughts, emotions, and nervous system, which I’ll be covering next.
