BRS6(PM9) - Stress-Induced Appetite / Reward Drive Modulation
1. Definition
Stress-related modulation of appetite, reward drive, and food-seeking behaviour through cortisol, catecholamine, and metabolic signals.
2. Mechanistic Basis
↓ stress-driven cravings; ↑ appetite stability; ↑ reward-system steadiness
3. Dependencies
3.1 KCs (Key Constraints)
- [MISSING_KC_FROM_COLUMN_C]
3.2 Optional BRSX Modifiers
- None listed
3.3 Co-factors
- magnesium
- B vitamins
- protein sufficiency context
4. Dietary Modulation
protein-rich breakfast → appetite stability; low-glycaemic meals → reduced crash-driven seeking; stress regulation → ↓ cortisol eating pressure; sleep optimisation → ↓ appetite dysregulation
5. Functional Outputs (Directional Effects)
↓ stress-driven cravings; ↑ appetite stability; ↑ reward-system steadiness
6. System Integration
Integrated within BRS6(FM4) as a behaviour-adjacent mechanism linking stress physiology with appetite and reward-drive modulation.
7. Key Insight
PM8 describes how stress-state alters food-seeking behaviour and appetite control, making neuroendocrine context central to dietary stability.

11. Notes
- Evidence Type: Human + mechanistic
- Evidence Notes: Behaviour-adjacent but still mechanistic: maps stress physiology onto appetite/reward regulation.
