Weight Loss on GLP-1 Medications
Typical Rate of Loss
- Most people lose 1-2 lbs per week initially, slowing over time
- Total loss over 12-18 months: roughly 15-22% of body weight on average with semaglutide (Ozempic/Wegovy) or tirzepatide (Mounjaro/Zepbound)
- Tirzepatide tends to outperform semaglutide, with some studies showing ~22% body weight loss
Specific Brands to Consider
- Wegovy (semaglutide) – FDA-approved specifically for weight loss
- Zepbound (tirzepatide) – currently showing the strongest results in trials
- Mounjaro – tirzepatide approved for diabetes but widely prescribed off-label for weight
The Sustainability Question (Be Honest With Yourself)
⚠️ This is the critical issue:
- Most people regain significant weight (often 2/3 of what they lost) within 1-2 years of stopping
- These medications likely need to be taken indefinitely to maintain results
- Cost ($900-$1,300/month without insurance) is a real barrier long-term
Bottom Line
They work very well short-term, but sustainability depends on staying on the medication AND building lasting habits around diet and exercise simultaneously.
