Weight Loss on GLP-1 Medications
Typical Speed of Loss
- First 1-3 months: Usually 1-2 lbs per week as your body adjusts
- Months 3-12: Loss often continues but may slow to 0.5-1 lb/week
- Clinical trials show: Most people lose 15-22% of body weight over 12-18 months
Specific Medications & Results
- Wegovy (semaglutide): ~15% average body weight loss in trials
- Zepbound (tirzepatide): ~20-22% — currently the strongest results available
- Ozempic (semaglutide): Prescribed off-label for weight loss, similar to Wegovy
The Sustainability Question — Be Honest With Yourself
The hard truth: Most research shows weight returns if you stop the medication, often 2/3 of lost weight within a year.
To make it more sustainable:
- Use the appetite suppression window to build lasting habits
- Work with a registered dietitian — services like Noom Med or Found combine medication with coaching
- Maintain muscle with strength training (crucial)
- Discuss long-term medication plans with your doctor upfront
Bottom Line
Results can be dramatic, but GLP-1s work best as a long-term tool, not a short-term fix. Have a frank conversation with your prescriber about your exit strategy.
