The Hunger Signal Glitch: Relearning Your Body’s Language Through Interoception

Have you ever looked at the clock and realized it’s 4:00 PM, and you haven’t eaten a single thing since breakfast? Or perhaps you find yourself feeling suddenly irritable, dizzy, or plagued by a "brain fog" that won't lift, only to realize: after much detective work: that your body is actually crying out for fuel?

If the standard advice of "just listen to your body" or "eat when you’re hungry" feels less like helpful guidance and more like a riddle in a language you don’t speak, you aren’t alone. You aren't failing at being a human, and you certainly aren't "broken." What you’re likely experiencing is what we call the hunger signal glitch.

At The Eating Disorders Clinic, we work with many individuals: particularly those who are neurodivergent: who find that their internal communication system isn't sending the "typical" signals. This breakdown in communication is rooted in a biological process called interoception.

In this post, we’ll explore why this glitch happens, how neurodivergence (like ADHD and Autism) plays a role, and: most importantly: how you can use sensory-based tools to build a new, compassionate relationship with your body’s needs.

What Exactly is Interoception? (The "Eighth Sense")

We’re all taught about the five basic senses: sight, smell, taste, touch, and hearing. You might even know about the sixth and seventh: vestibular (balance) and proprioception (body position). But the eighth sense, interoception, is the one that tells you what’s happening inside your body.

Interoception is your internal GPS. It’s the collection of sensors in your organs, skin, and muscles that send messages to your brain about:

• Hunger and fullness

• Thirst

• Heart rate

• The need to use the bathroom

• Body temperature

• Emotional states (the "butterflies" of anxiety or the "heaviness" of sadness)

For many people, these signals are like a clear, steady radio broadcast. For others, the signal is fuzzy, intermittent, or completely silent until it reaches a "shouting" volume.

The Glitch: Why the Signal Fades

When we talk about the "hunger signal glitch," we are describing a mismatch between what your body needs and what your brain perceives. This is particularly common in the neurodivergent community.

1. The Hyperfocus Filter (ADHD)

If you have ADHD, your brain’s ability to regulate attention can override interoceptive signals. When you are "locked in" to a task: whether it’s a creative project, a video game, or an intense work session: your brain effectively mutes all "non-essential" notifications. Your stomach might be sending hunger signals, but they are blocked at the gate. By the time you "snap out" of your focus, you might feel shaky, nauseous, or overwhelmed by a sudden, intense hunger that feels impossible to manage.

2. Sensory Processing Differences (Autism & ARFID)

For autistic individuals or those with ARFID (Avoidant/Restrictive Food Intake Disorder), the sensory experience of the world is heightened. Sometimes, external sensory input (loud noises, bright lights, the texture of clothing) is so loud that internal signals simply can't compete.

Furthermore, "hunger" doesn't always feel like a rumbling stomach. It might feel like a headache, a sudden drop in mood, or an increase in sensory sensitivity. If you don't recognize these as "hunger," you might try to solve the wrong problem: reaching for noise-canceling headphones when what you actually need is a snack.

3. The Impact of Trauma and Stress

When the body is in a state of high alert (fight-or-flight), it deprioritizes digestion. If you are living with high levels of anxiety or past trauma, your nervous system may have "learned" to suppress hunger signals as a survival mechanism. This creates a cycle where you are perpetually under-fueled, which in turn keeps your nervous system in a state of stress.

Why "Intuitive Eating" Can Feel Invalidating

The "Intuitive Eating" movement has done wonderful work in de-stigmatizing food, but for someone with an interoception glitch, its core tenets can feel frustratingly out of reach. If you don't feel "intuitive" signals, being told to trust them can feel like being told to "just see" when you don't have your glasses on.

At our clinic, we believe in informed eating over purely intuitive eating. This means using a combination of internal curiosity and external scaffolding to ensure your body stays safe and regulated. We move away from "shoulds" and toward a formulation-based understanding of your unique sensory profile.

Sensory-Based Tools to Re-Sync Your System

If the internal radio is glitchy, we can use "external antennas" and sensory mapping to bridge the gap. Here are some gentle next steps you can explore at your own pace.

1. Sensory Mapping: The "Body Fuel" Scan

Instead of looking for a "growling stomach," start looking for "secondary hunger signals." Try checking in with yourself three times a day. Don't ask, "Am I hungry?" Ask:

• Energy: On a scale of 1-10, how is my battery?

• Focus: Is my brain feeling "foggy" or sharp?

• Irritability: Am I feeling "snappy" for no clear reason?

• Physical: Is my mouth dry? Is my head heavy?

By mapping these sensations, you might find that "irritability" is actually your body’s unique way of saying it needs glucose.

2. External Scaffolding (The "Supportive Skeleton")

If your brain doesn't send the signal, we use technology to send it for us. This isn't about rigid "dieting"; it's about biological safety.

• Non-Negotiable Intervals: Set gentle phone reminders to check in with food every 3-4 hours.

• Visual Prompts: Keep "safe" and easy-to-grab snacks in your direct line of sight.

• The "Mechanical" Phase: Sometimes, we eat because it is "time to fuel," even if the hunger signal is absent. Think of it like charging your phone before the battery hits 0%.

3. Sensory-Friendly Food Preparation

Sometimes the process of eating is the barrier. If you are sensory-overloaded, a complex meal with multiple textures might be too much.

• Safe Foods: Keep a list of foods that are sensory-consistent (like a specific brand of yogurt or crackers). These require less "sensory work" to consume.

• Temperature Tweaks: Some people find cold foods easier to manage when they are stressed, as they feel "cleaner" and less aromatic.

Understanding Before Intervention

At The Eating Disorders Clinic, our approach is neurodiversity-informed. We don't try to "fix" your autism or ADHD to get you to eat; we work with your neurodivergent brain to find a path that feels safe.

Our multidisciplinary team: including dietitians, psychologists, and occupational therapists: helps you create a "user manual" for your specific body. We look at:

• Formulation: Why is this happening for you specifically?

• Sensory Profile: What are your sensory "yums" and "yucks"?

• Executive Function: How can we make eating require less mental energy?

We recognize that the journey is heterogeneous: what works for one person won't work for another. Our goal is to move you from a place of "fighting" your body to a place of collaborative care.

A Gentle Next Step

Relearning your body’s language is not a fast process. It’s a series of small, low-pressure experiments. You might spend a week just noticing how your eyes feel when you’re thirsty, or another week testing if a vibrating alarm on your watch helps you remember to have a snack.

If you feel like your "hunger signal glitch" is impacting your quality of life, or if you’re struggling with more complex challenges like anorexia, bulimia, or binge eating, we are here to help.

Our care is delivered online, fitting into your life rather than demanding you change your life to fit a rigid treatment model. We offer specialist support for children, adolescents, and adults, with a deep understanding of the intersection between mental health and neurodivergence.

You don’t have to solve the glitch alone.

If you’d like to explore how we can support you in understanding your body’s unique signals, we invite you to look through our service fees or simply get in touch for a low-pressure conversation. We are here to listen, to understand, and to help you find your way back to a sense of internal safety.
