The hunger and fullness scale, and how to use it at a meal
Published October 7, 2026
A hunger and fullness scale is a quick way to check in with your body: a number from 1 (empty) to 10 (painfully full) for how you feel right now. It works best at three moments in a meal, and the numbers are for noticing, not for grading yourself.
The scale
| Number | How it feels |
|---|---|
| 1 | Empty and shaky. Hard to think about anything but food. You may feel lightheaded or irritable. |
| 2 | Very hungry. Your stomach is growling and your energy is low. Waiting feels hard. |
| 3 | Hungry. Clearly ready to eat, without any rush. A good moment to start a meal. |
| 4 | A little hungry. You could eat now, or wait a while without minding. |
| 5 | Neutral. Neither hungry nor full. |
| 6 | Lightly full. The hunger has gone, and you could still eat more. |
| 7 | Comfortably full. Satisfied and content. You'd be happy to stop here. |
| 8 | Quite full. A little heavier than comfortable. |
| 9 | Uncomfortably full. Tight and heavy, maybe sleepy. |
| 10 | Painfully full. You may feel sick. |
Dietitians' handouts use the same idea with slightly different words, and some run from 0 to 10. One from Alberta Health Services suggests starting to eat around 3 or 4, when hunger is clear but calm, and thinking about stopping around 5 or 6. Treat ranges like these as a starting point; your own comfortable numbers may sit a little higher or lower.
Three moments to check in
- Before you start. Where are you? If the answer is often 1 or 2, meals tend to start in a rush. A snack earlier, or an earlier meal, can bring you to the table at a 3.
- Halfway through. Put your fork down, take a breath and pick a number. It's the most useful of the three, because it comes while you can still decide what to do next: keep going, slow down, or finish. In Choo, an optional belly check asks this halfway through a meal, with a five-step bowl that fills up.
- About 20 minutes after. Fullness keeps arriving after the last bite, so the number after a meal can be higher than the number at the end of it. There is more on why in how long does it take to feel full.
What to do with your numbers
Nothing, at first. For a week or so, just notice them. Then look for patterns; they tend to point somewhere useful:
- You often start at 1 or 2. Long gaps between meals make any meal feel urgent. Steadier meals or a small snack may help more than any eating technique.
- You often finish at 8 or 9. Often the meal simply ended before the fullness signals caught up. A pause halfway and a slower start help. See how to eat slower.
- You often eat at a 5. Eating by the clock, for company or for comfort is part of normal life. The scale just makes it visible, so it becomes a choice.
- You can't tell. Common, especially at first, or if you've spent years eating quickly or on a schedule. It gets easier with practice.
Why a number helps
Hunger and fullness are feelings, and feelings are easier to notice when you have to put a number on them. Researchers rely on the same trick: appetite studies use simple hunger and fullness scales, and a study of 55 men found these give consistent results from one day to the next. You don't need that precision. A rough number, picked honestly, is enough.
When your signals have changed
After bariatric surgery, or on a GLP-1 medication, hunger can be faint and fullness can arrive after a few bites and feel different from before. The scale can help you learn your new signals, alongside the plan your care team gave you. See how to eat slowly after bariatric surgery.
If you're in recovery from an eating disorder, a scale like this can turn into a set of rules. Use it only with your care team's support. And if you often feel out of control around food, or upset after eating, talk to a doctor or dietitian.
