- Month 2-3: Dose increases, consistent 1-2 lbs per week weight loss
- Month 4-6: Approaching therapeutic doses, steady progress continues
- Month 6-12: Maximum dose reached, weight loss may slow but continues
- Month 12-18: Approaching peak results, weight stabilization phase
Maximizing Your Results
The most successful GLP-1 patients combine medication with high protein intake (1g per pound of ideal body weight), resistance training (2-4 times per week), adequate hydration, and quality sleep. These lifestyle factors can significantly enhance your medication's effectiveness.
