- GLP-1 Agonists (Semaglutide, Tirzepatide)
- Slows gastric emptying, extends satiety signaling, delays ghrelin rebound
- 15–22% body weight over 68–72 weeks
- Addresses age-related leptin resistance and compensatory hunger mechanisms
- Nausea, vomiting, diarrhea in 30–45% during titration; resolves in 4–8 weeks
- Strongest clinical evidence for sustained fat loss; first-line choice for most over-50 populations
- Growth Hormone Secretagogues (CJC-1295, Ipamorelin, MK-677)
- Stimulates endogenous GH release, preserves lean mass during caloric deficit
- 1.1kg lean mass gain; indirect fat loss via metabolic rate preservation
- Prevents sarcopenia and metabolic slowdown during restrictive diets
- Water retention, increased appetite, transient joint stiffness
- Best for individuals prioritizing muscle preservation; requires concurrent caloric deficit for fat loss
- Metabolic Modulators (Tesofensine)
- Dopamine/norepinephrine/serotonin reuptake inhibition; increases TDEE and reduces hedonic eating
- 10.6% body weight over 24 weeks
- Targets reward-driven eating and postmenopausal decline in satiety signaling
- Dry mouth, insomnia, increased heart rate in 15–25%
- Mechanistically distinct alternative for GLP-1 non-responders; limited long-term safety data beyond 24 weeks
