Tool
What is the hunger-fullness scale?
The hunger-fullness scale is a simple 1–10 self-rating people use before, during, and after meals to notice where their body actually is — somewhere between empty and overfull. It's a tool for awareness, not a metric to optimise.
Definition
The hunger-fullness scale is a 1-to-10 self-rating tool for noticing physical hunger and fullness, used in mindful and intuitive eating practice to bring attention to internal body signals around meals.
The scale, in plain numbers
Most versions of the scale run 1 to 10. The exact phrasing varies by clinician and book, but the structure is consistent: low numbers are physical emptiness, mid-range is comfortable, high numbers are physical fullness — past the point most people want to be.
- 1–2: Painfully empty. Light-headed, irritable, hard to think.
- 3–4: Hungry. Stomach signals are clear; you'd reach for food now.
- 5–6: Comfortably neutral or just satisfied. Food is fine, not urgent.
- 7–8: Full. The plate's been enough; another bite would be a choice, not a need.
- 9–10: Past full. Tight, sluggish, regret-adjacent.
What it's for — and what it isn't
The scale is a noticing tool. Most people who try it learn that they often eat without checking — they reach for food without rating their hunger, and finish meals without rating their fullness. Just rating, even occasionally, builds the habit of checking in.
It is not a rule. There's no 'correct' number to start a meal at and no number you must stop at. Some intuitive-eating teachers suggest starting around 3–4 and stopping around 6–7, but those are rules of thumb, not laws. The value of the scale is the act of paying attention, not the precision of the rating.
Why ratings drift over time
After repeated practice, most people's ratings become more nuanced — they distinguish 'a bit hungry' from 'really hungry' more reliably, and they start to notice the difference between physical fullness and emotional fullness (eating to soothe, eating because the food is good, eating because the meal is over). That nuance is the actual point: the number is just a way to ask the question.
How to use it — three checkpoints
-
Before the first bite
Before you start, rate your hunger 1–10. Don't agonise — first instinct. Notice if the answer surprises you (often it does — many people eat at 5–6, not 3–4).
-
Halfway through
Halfway through the meal, set the fork down and rate again. Are you climbing into the satisfied range? Still hungry? Already past full? Pausing gives the body's slower satiety signals time to register.
-
When you stop
When you stop eating, rate one more time. There's no judgement attached — the number is just data. Over weeks, patterns emerge that no calorie count can show.
What the research says
-
Kokkinos A. et al. (2010)
Eating slowly increased postprandial satiety hormones (PYY, GLP-1) — supporting the use of mid-meal fullness checks, since those signals lag eating.
-
Andrade A.M., Greene G.W., Melanson K.J. (2008)
Slow eating reduced intake within meals — consistent with pausing to rate fullness so the brain can catch up to the stomach.
-
Robinson E. et al. (2014)
Attentive-eating interventions (which include attention to hunger and fullness signals) reduced subsequent food intake across 24 reviewed studies.
-
Robinson E. et al. (2013)
Distracted eaters had impaired recall of recent eating and ate more later — pointing to the role of attention (and self-rating) in reading internal signals.

Frequently asked
What numbers should I aim for?
There is no required answer. Many intuitive-eating teachers suggest starting meals around 3–4 and stopping around 6–7, but those are guides, not rules. The point is to notice — not to hit a target.
What if I can't tell what I'm feeling?
Common at first — especially after years of dieting, which trains people to ignore body signals. Just guess. Over time, the guesses get sharper. Some people pair the scale with a body-scan: where in the body am I noticing this?
Is this just a portion-control trick?
It can be used that way, but that's not what makes it useful. Treated as portion control, it tends to backfire (it becomes another rule). Treated as a noticing tool — 'where am I actually?' — it builds the kind of self-trust that lasts.
Does How It Felt include this?
Yes. How It Felt's hunger and fullness sliders are a version of this scale, captured per entry alongside emotion. The ratings are private and never produce a score or trend metric.
