Here’s a clean, structured interpretation of the diagram you uploaded — turning it into something clinically useful, parent‑friendly, and ready to drop into a letter or teaching session.
🧠 Core idea
Three different types of hunger drive eating behaviour, and eating behaviour drives weight change when energy intake exceeds energy expenditure.
🍽️ Types of hunger
Each hunger type influences eating in a different way. These distinctions are clinically helpful when exploring patterns with families.
Homeostatic hunger — Physiological need for energy; triggered by low glucose, empty stomach, hormonal signals (ghrelin ↑, leptin ↓).
- Predictable, slow onset
- Resolved by any adequate food
- Adaptive and necessary
Hedonic hunger — Eating for pleasure, reward, or emotional soothing rather than energy need.
- Driven by dopamine pathways
- Triggered by palatable foods, stress, boredom
- Often leads to overeating
Conditioned hunger — Learned cues that trigger eating regardless of physiological need.
- Time‑of‑day cues (“I always snack at 8 pm”)
- Environmental cues (TV, cinema popcorn)
- Social cues (eating because others are eating)
🔄 How hunger → eating behaviour
Eating behaviour is shaped by the interaction of these hunger types and determines:
- What we eat — nutrient density, palatability, availability
- Where we eat — table vs sofa vs on‑the‑go
- When we eat — structured meals vs grazing
- How much we eat — portion size, speed, emotional state
These behaviours are modifiable, which is why they’re often the focus of paediatric weight‑management interventions.
⚖️ Eating behaviour → weight gain
Weight gain occurs when:
[ \text{Calories In} > \text{Calories Out} ]
This imbalance is influenced by:
- Energy intake — portion size, snacking, sugary drinks
- Energy expenditure — physical activity, sedentary time
- Metabolic factors — genetics, sleep, stress
🧩 Clinical usefulness
This framework helps you:
- Explain to parents why “just eat less” is overly simplistic
- Identify which hunger type is driving problematic eating
- Target interventions (e.g., structure for conditioned hunger, emotional regulation for hedonic hunger)
- Normalise the child’s experience (“This isn’t lack of willpower; it’s how the brain works”)
