When Hunger Doesn’t Shout: ADHD, Interoception and Our Relationship With Food
For many people, eating seems fairly straightforward.
You get hungry. You notice you’re hungry. You decide what you want. You make something. You eat it.
But that apparently simple sequence actually requires quite a lot from the brain.
You have to detect an internal bodily signal, recognise what it means, shift your attention towards it, make a decision, initiate an action and follow that action through.
For some people with ADHD, difficulties can occur at almost every stage of that process.
And that may help explain some eating patterns which, viewed from the outside, can look inconsistent, impulsive or simply puzzling.
Interoception: hearing what the body is saying
Interoception is our ability to perceive and interpret signals originating inside the body.
Hunger and fullness are part of it, but so are thirst, temperature, heartbeat, nausea, pain, fatigue and the need to use the toilet.
Importantly, interoception isn’t simply a matter of whether the body produces a signal.
There is also the question of whether we notice it, correctly identify it and respond to it.
Someone might therefore go for hours without consciously experiencing hunger, only to suddenly realise that they feel shaky, irritable, nauseous, headachy or completely depleted.
The body may have been signalling for some time.
The signal simply didn’t win the competition for attention.
This is particularly interesting in ADHD because attention isn’t just about being unable to concentrate. It is also about the regulation and allocation of attention.
When someone is deeply absorbed in work, a project, gaming, caring for somebody else or simply getting through a busy day, relatively quiet internal signals can be remarkably easy to miss.
By the time hunger becomes impossible to ignore, gentle hunger may have become urgent hunger.
And urgent hunger changes behaviour.
“I forgot to eat… and now I want everything”
This can create a pattern that is easily mistaken for a simple lack of self-control.
Little food is eaten during the day.
Hunger signals are missed or postponed.
Energy falls.
Executive resources are already depleted.
Then, in the evening, the person suddenly becomes extremely hungry and reaches for foods that are immediate, rewarding and require little effort.
That might mean eating considerably more at night, grazing continuously, reaching for highly palatable foods or ordering a takeaway despite having food in the fridge.
The behaviour at 9pm makes much more sense when we look at what happened at 9am, 1pm and 5pm.
Sometimes the issue isn’t excessive appetite.
It is delayed response to appetite.
Knowing how to cook isn’t the same as being able to make dinner
This is where executive function enters the picture.
“Make something to eat” sounds like one task.
It isn’t.
You have to decide what to eat, check ingredients, sequence the steps, gather what you need, begin preparing it, monitor time, tolerate interruptions, complete the meal and often clean up afterwards.
Someone can be perfectly capable of cooking and still stand in front of a full fridge feeling completely unable to begin.
That’s an important distinction.
Knowledge is not initiation.
And when hunger, tiredness, decision fatigue and executive dysfunction converge at the end of a day, the threshold for starting can become even higher.
Hence the apparently ridiculous situation of ordering food while perfectly good groceries slowly expire six inches away.
From an executive-function perspective, it isn’t ridiculous at all.
The takeaway has removed most of the cognitive steps.
And then there are “food phases”
Another pattern many neurodivergent people recognise is finding a particular food and eating it repeatedly.
Same breakfast.
Same lunch.
Same snack.
Every day.
Until one morning you look at your formerly beloved food and would rather eat the plate.
There are several possible mechanisms here, and we should be careful not to reduce all of them to dopamine.
Familiar foods reduce decision-making. They are predictable. Their taste, texture, smell and preparation are known. For somebody dealing with sensory sensitivities or decision fatigue, that predictability can be extremely useful.
Novelty and reward may also play a part. Something initially interesting or highly rewarding can become less compelling through repetition.
So familiarity can initially make a food easier to choose, while habituation may eventually make it less appealing.
The resulting behaviour can look contradictory:
“I only want this.”
followed three weeks later by:
“I never want to see this again.”
But those two responses may arise from the same nervous system balancing predictability, effort, sensory experience and reward.
What about cravings?
Crunchy. Salty. Sweet. Cold. Fizzy. Strongly flavoured.
Food doesn’t only provide nutrition.
It provides sensory input and reward.
Texture, temperature, taste and the physical act of chewing can all contribute to the experience of regulation and stimulation.
That doesn’t mean every craving in someone with ADHD is caused by ADHD — far from it. Hunger, sleep, learned associations, restriction, stress, medication, hormones, metabolic factors and individual preference all matter.
But it does mean that asking “What is this person getting from this food?” may sometimes be more useful than simply asking why they haven’t chosen something supposedly healthier.
The missing link may be the sequence
Perhaps one of the most useful ways to understand food difficulties in ADHD is to stop looking at eating as a single behaviour.
Instead, consider the chain:
Body signal → awareness → interpretation → attention → decision → initiation → action → regulation
A difficulty anywhere along that chain can change what eventually happens on the plate.
That also explains why simply giving someone nutritional information may not solve the problem.
They may already know exactly what a balanced meal looks like.
The difficulty may be noticing hunger early enough.
Or disengaging from another activity.
Or choosing between twelve possible meals.
Or tolerating the sensory properties of available food.
Or initiating preparation.
Or having enough executive energy left at the end of the day to turn ingredients into dinner.
Those require different solutions.
Understanding the pattern changes the question
None of these behaviours is diagnostic of ADHD, and similar patterns can occur for many other reasons. Significant binge eating, restriction, unexplained appetite or weight changes, or symptoms such as recurrent shakiness also deserve proper assessment rather than automatically being attributed to neurodivergence.
But for people with ADHD who recognise these patterns, understanding the mechanisms can remove some of the moral judgement that so often surrounds eating.
Instead of:
“Why can’t I just eat properly?”
perhaps the more useful questions are:
When do I actually notice hunger?
What happens between noticing it and eating?
Where in that sequence does the process tend to fall apart?
Because sometimes the difficulty isn’t knowing what your body needs.
It’s noticing the message, switching attention to it, and getting the brain and body organised enough to respond.
