- Semaglutide
- GLP-1 receptor agonist. Slows gastric emptying, extends satiety signaling 90–120 min post-meal
- Strong (Phase 3 RCTs, FDA-approved for weight management)
- 0.25–2.4mg weekly subcutaneous
- Emotional eating driven by rapid ghrelin rebound post-meal
- Best-supported peptide for emotional eating. Directly targets satiety pathways disrupted by stress
- Tirzepatide
- Dual GLP-1/GIP receptor agonist. Combines satiety extension with insulin sensitivity improvement
- Strong (Phase 3 RCTs, FDA-approved)
- 2.5–15mg weekly subcutaneous
- Emotional eating with insulin resistance or metabolic syndrome
- Strongest weight loss data; dual mechanism addresses both hunger and metabolic dysfunction
- MK-677
- Ghrelin receptor agonist. Increases GH/IGF-1, may desensitize ghrelin receptors long-term
- Moderate (Phase 2 data, not approved for appetite)
- 10–25mg daily oral
- Research into ghrelin receptor dynamics. Not acute appetite suppression
- Increases hunger acutely; research use only for receptor desensitization studies
- Hexarelin
- Growth hormone secretagogue with CRH modulation in preclinical models
- Weak (animal models only for stress-eating)
- 100–200mcg twice daily subcutaneous
- Stress-driven eating via hypothalamic cortisol pathways
- Promising mechanism but lacks human emotional eating data
- Cerebrolysin
- Neurotrophic peptide. Promotes neuroplasticity and emotional regulation
- Moderate (human trials for cognitive function, not eating behavior)
- 10–30mL IV over 10–20 sessions
- Cognitive retraining for prefrontal override of limbic hunger
- Indirect mechanism. Improves executive control rather than appetite signaling
