## Content

Review paper examining GLP-1 receptor agonists' effects on appetite regulation and eating disorder risk across different eating disorder subtypes. Published in MDPI Nutrients, archived on PMC (PMC12694361).

Key findings:
- GLP-1 RAs reduce hunger, increase satiety, dampen cravings, and influence food choice by activating brain regions controlling fullness and modulating reward circuits
- Users typically experience smaller meals, longer eating intervals, and reduced emotional eating short-term — but these benefits may not persist long-term
- Opposing mechanism paradox: beneficial for BED (reduces binge episodes via mesolimbic dopamine), potentially harmful for restrictive EDs (enhanced satiety reinforces restriction in vulnerable individuals)
- Highest-risk populations: individuals with restrictive eating disorder histories (AN, atypical AN), those with high perfectionism or OCD traits, adolescents during critical development, racial/ethnic minorities facing intersectional stigma

Clinical recommendations:
1. Pre-treatment screening: SCOFF questionnaire for eating disorder history, compensatory behaviors, body image, and emotion regulation
2. Ongoing monitoring: track eating behaviors, mood, and suicidal ideation; heightened vigilance during dose escalations
3. Multidisciplinary approach: psychological care + dietitian + medical oversight (not standalone medication)
4. Preventive strategies: introduce DBT/mindfulness BEFORE appetite suppression eliminates food-based coping
5. Conclusion: GLP-1s "must be approached with caution: integrated into multidisciplinary care with rigorous monitoring" until long-term safety in diverse populations established

Research gaps: "extremely limited" evidence on anorexia nervosa specifically; theoretical risks include appetite suppression masking restrictive behaviors, compulsive reliance on medication for control, reinforcement of maladaptive food rules

## Agent Notes
**Why this matters:** This is the most comprehensive review connecting GLP-1 pharmacology specifically to eating disorder risk by subtype — it operationalizes the paradox that the same mechanism (GLP-1R-mediated appetite suppression) is protective for BED and potentially harmful for AN. This is the mechanistic frame needed to interpret the VigiBase aROR 4.17-6.80 signal.

**What surprised me:** The finding that benefits (smaller meals, reduced emotional eating) "may not persist long-term" — even for BED — suggests GLP-1 is not a durable behavioral treatment for any eating disorder subtype. This is consistent with the continuous-treatment dependency pattern established in earlier sessions for metabolic indications.

**What I expected but didn't find:** Specific RCT evidence for GLP-1 in anorexia nervosa (AN) — the paper confirms this is essentially absent. The AN evidence base is entirely theoretical/mechanistic.

**KB connections:**
- [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]] — eating disorder risk constrains behavioral health expansion
- [[human-in-the-loop clinical AI degrades to worse-than-AI-alone]] — parallel to GLP-1 creating unintended behavioral consequences
- [[behavioral primacy — health outcomes 80-90% determined by non-clinical factors]] — this paper argues behavioral risk factors (ED history, perfectionism) are the primary determinant of whether GLP-1 helps or harms

**Extraction hints:** Multiple claim candidates: (1) GLP-1 eating disorder risk is subtype-specific — protective for BED, potentially harmful for restrictive EDs; (2) no RCT evidence for GLP-1 in AN exists despite pharmacovigilance signals; (3) pre-treatment ED screening is recommended but not required by any professional guideline or regulatory body

**Context:** This is a broad narrative review, not an RCT or systematic review. Useful for the mechanistic argument but not primary evidence.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]]
WHY ARCHIVED: Mechanistic framework for interpreting the pharmacovigilance eating disorder signal — explains WHY the signal exists via subtype-specific GLP-1R mechanism
EXTRACTION HINT: Focus on the BED-protective vs. AN-harmful mechanism distinction; extractor should NOT collapse eating disorders into a single category
