Interoceptive Awareness
Interoceptive awareness is the ability to notice and interpret internal body signals such as hunger, fullness and thirst, and it is often blunted in obesity and disordered eating.
Plain English
Patient-Friendly Explanation
Interoception is your sense of what is happening inside your body: an empty stomach, a full one, a racing heart or a dry mouth. People differ in how clearly they read those signals. When the messages that say "I am hungry" and "I am full" are faint or misread, it becomes harder to eat in response to genuine need and easier to eat in response to mood, habit or the sight of food. The skill can be improved: slowing down at meals and checking in with your body before you eat are simple ways to sharpen it.

Clinical Definition
Interoceptive accuracy is measured with tasks such as the heartbeat detection task and self-report instruments such as the Multidimensional Assessment of Interoceptive Awareness. Adults with obesity and people with binge-eating disorder show reduced interoceptive accuracy together with a stronger tendency to eat in response to external and emotional cues, and satiety signals such as gastric distension and postprandial gut-peptide release are perceived less reliably. The relationship is not simply linear: heightened interoceptive sensitivity, particularly to cardiac sensation, is a maintaining factor in panic and anxiety disorders, and anxiety about bodily sensations can itself distort eating behaviour. Bariatric procedures alter vagal afferent signalling and are reported to change interoceptive processing. Mindful eating and interoceptive exposure training aim to restore discrimination between hunger, appetite and emotional arousal.
Key Insight
Why It Matters
A great deal of what patients describe as a lack of willpower is a perception problem rather than a motivation problem, and perception can be trained, which makes it a more encouraging conversation than one about discipline.
