How to tell if you're hungry, full, or just want to eat

Hunger and fullness cues are the signals your body sends to start and stop eating. Mela Theory, the framework behind Nutrimelab, reads them as information that many of us learned early to talk over, and that you can learn to hear again. Progress means more trust around food, with nothing weighed or counted.

Say it's half past four on a weekday. The biscuit tin is open on the counter, there's one in your hand, and you honestly couldn't say whether you're hungry. Lunch was at one, or was it half twelve? You're a bit tired, there's a meeting at five, and your stomach isn't saying much either way. Your hand got to the tin before the question did.

If that moment is familiar, nothing is wrong with you. Before any practice, it helps to know what you're listening for, and why it can be hard to hear.

Intuitive Eating is an approach created by dietitians Evelyn Tribole and Elyse Resch, first published in 1995. It is weight-neutral, which means its aim is a working relationship with food and your body, not a number on a scale. What follows is my own teaching, shaped by that approach and by what I see in my work.

What does hunger feel like in an adult body?

Hunger in an adult body usually builds slowly. It can feel like an empty or hollow stomach, energy that dips, concentration that wanders and a shorter temper, and it tends to accept most foods. Hunger cues in adults vary from person to person and from day to day, so your own version is the one worth learning.

Search for hunger cues and most of what comes back is about babies, who cry, root and suck their fists when they want feeding. Adult cues are quieter and more personal than that. They often shift with age, with how busy you are, with how well you slept and with how long it has been since you last ate, so Saturday's hunger may not look much like Wednesday's.

Physical signs

The physical signs are the ones most people expect. Your stomach might feel empty or hollow, or rumble loudly enough for the person next to you to hear. Energy drops in the mid-afternoon, you read the same line of an email twice, and you find yourself short with someone who didn't deserve it. Not everyone gets all of these. Some people barely feel their stomach and notice hunger first as irritability or a foggy head, which is every bit as much a hunger cue as a rumble.

Mental and practical signs

Hunger also shows up as thought. Your mind drifts to food, you start planning what you'll have later, or every advert on the bus seems to be for crisps. Then there are the practical signs, which have little to do with how you feel right now. It has been five hours since you last ate. You have a long train home and nothing in your bag. You're about to go into a three-hour meeting with no break.

Practical hunger is the body's needs read from the diary, and it counts. Eating now because you know you'll be hungry at six is a sensible decision.

How do I know if I'm hungry or just want to eat?

You can usually tell by how the wanting arrives and what it will accept. Hunger builds over a while, sits in the body and would take most reasonable foods. Wanting to eat without hunger tends to arrive quickly, often after a cue or a feeling, and wants one thing in particular. Both are normal, and both tell you something.

The title of this article names three states, and they're easier to tell apart side by side.

| | Hungry | Full | Just want to eat | | --- | --- | --- | --- | | How it arrives | Slowly, over an hour or two | Gradually, and often later than you'd expect | Quickly, often after something happens | | Where you feel it | Stomach, energy, mood | A settled stomach, less interest in the plate | In the mouth or the mind more than the stomach | | What it will accept | Most things | Very little, unless it's something you love | Usually one food |

Wanting to eat when you aren't hungry is ordinary. Food tastes good, it's sociable, and a biscuit with a cup of tea at four o'clock is one of the small pleasures of a working day. I'd treat that wanting as information about the moment. Sometimes the right answer is to have the biscuit and enjoy it properly. Sometimes the wanting is pointing at something else. It might be a dull afternoon or an email you're avoiding, or a feeling you haven't named yet. Telling those apart is a separate question with its own article, on whether you're hungry or bored.

In my work I see that when eating without hunger is treated as a lapse, people tend to eat quickly and guiltily, which makes it harder to notice whether it helped. Asking "is this hunger?" works best as a real question, with either answer acceptable.

How do you know when you're full?

You know you're full when food starts to taste less interesting and your stomach feels settled. You could stop without minding. Mela reads fullness as the quieter of the two signals, often noticed a little after you've had enough, which can make it easy to carry on past it.

Comfortable fullness is a pleasant feeling, the point where you could get up and go for a walk without wanting to lie down first. What that feels like in practice, and why the signal is easy to miss, is the subject of what comfortable fullness feels like.

One more thing confuses a lot of people. You can be full and still not feel finished. Full is not the same as satisfied. Mela reads a meal that filled you without pleasing you as one that often sends you back to the cupboard half an hour later, looking for whatever was missing.

Why can't I tell when I'm hungry any more?

In my work, most people who tell me they can't feel hunger any more have spent years eating by the clock or by a rule, often at a screen. Hunger and fullness were rarely the thing deciding when they ate or stopped. Mela reads the signals as fading into the background after that. With regular meals and some attention, they often become easier to hear again.

Research on interoception, the sense of what is going on inside your own body, gives a useful hint. In a study of 111 healthy young women, those who were more accurate at sensing their own heartbeat also tended to rely more on hunger and fullness cues when deciding when and how much to eat (Herbert et al., 2013). It was one group of young women measured at one point in time, so it shows a link and says nothing about what came first.

I treat hearing hunger as part of that wider skill of noticing your body, which is why the practice below is about attention rather than rules.

Distraction plays its part as well. A 2013 review that pooled 24 experiments on attention and eating found that, in the distraction studies, people ate somewhat more at that meal while distracted, and more again at a later meal, than people who ate without distraction (Robinson et al., 2013). These experiments measured how much people ate, so they say nothing about how well anyone hears their hunger. Mela reads eating at a desk or with a phone in your hand as one of the ways the signal often gets missed, and eating too fast to notice is its close relative.

Long gaps do the opposite job. After a long gap, hunger often stops being a polite signal and arrives all at once, usually at the least convenient moment, and that is why evenings get loud after a long gap. The setting around you plays its part too, from the size of the packet to the people at the table, and the cues around you that decide when you stop have their own article.

Mela describes this as two of its six layers working together. Biology is the body's signals themselves. Cues are everything around you that competes with them. Think of the clock and the screen, or the open tin and the colleague who always brings cake. Mela reads quiet hunger as a learned pattern in which the cues have had the final say for a long time, and a learned pattern can shift once the body is listened to more often.

Some people find their body's signals faint for reasons that have little to do with habit, and nothing here is meant to explain those away. If quiet hunger is one of several things about eating that have started to worry you, the signs of an unhealthy relationship with food are a sensible next read.

If you've lost touch with your hunger for a long time and that has started to frighten you, or food takes up much of your day, please talk to your GP, or contact Beat, the UK's eating disorder charity, at beateatingdisorders.org.uk, where you'll find their free helplines.

What the hunger and fullness scale is, and why I don't ask you to score yourself

The hunger and fullness scale is usually a 1 to 10 rating (some versions start at 0), where the low end means ravenous and the high end means uncomfortably stuffed. You rate yourself before, during and after a meal, and the idea is to notice where you tend to start eating and where you tend to stop. It is used by practitioners, including many who work with Intuitive Eating (Tribole and Resch), and it is what most people find when they search for how to tell if they're hungry.

I understand why it's popular. A number feels objective, and if your signals have gone quiet, being handed a ruler is a relief. The trouble I see is what happens next. Within a week the number tends to turn into a rule. Start at 3, stop at 7, and anyone who ate at a 6 or carried on to an 8 has failed a test they set themselves. For people who have spent years following food rules, a new rule with numbers attached is the last thing that helps.

One way researchers measure how much people rely on hunger and fullness is a questionnaire about how you usually eat. Across three studies with 1,405 college women and 1,195 college men, higher scores on one such questionnaire, the Intuitive Eating Scale-2, went with more body appreciation, higher self-esteem and more satisfaction with life (Tylka and Kroon Van Diest, 2013). These were students answering questionnaires at one point in time, so this is a link, and it can't tell you which came first.

So this series asks for noticing rather than scoring. You describe what you feel in your own words and leave it there. "Hollow" or "a bit foggy" is plenty. If you've used the scale before and it helped, keep it. If it turned into homework, put it down for this week.

This week's practice, one meal a day

Pick one meal a day this week, the same one each day if that's easier. Lunch works well for a lot of people because it's often the meal eaten at a desk or on the move. At that meal, pause briefly at three points.

Before the first bite, notice how hungry you are and where you feel it. When you put your fork down for the first time, notice how much you're enjoying the food. When you stop, notice how full you feel and whether you feel finished. A breath or two at each point is enough.

There are no numbers, no app and no notes, unless you like notes. Eat whatever you were going to eat, and as much as you want. Nothing here asks you to weigh, count, restrict or make up for anything, and if you miss a day, the next meal is the next chance. You may find by Friday that one of the three is easier to hear than the others, which is worth knowing.

Progress here, and across the six weeks, means trusting your hunger a little more, being more flexible when the day goes off plan, and eating feeling easier. It is never measured by weight.

Tomorrow, choose your meal before you get there, and let the first bite be your reminder to pause.

Where this fits my programme

This is the second week of a six-week map I use for improving your relationship with food without a diet. Week 1 looked at where the rules came from, and next week I look at the evenings when hunger is not the reason you're reaching for food.

In my 7-week programme, this is the kind of work we do together, in a small group.

Everything in this series is education rather than treatment. If you'd like a professional alongside you, when to see a dietitian explains who does what in the UK and how to find them.
