Which One Is More Effective?
Tirzepatide is more effective for weight loss based on clinical trial data:
Semaglutide (STEP 1 trial - Wegovy 2.4mg):
- Average weight loss: 14.9% of body weight
- 50% of patients lost ≥15% body weight
- 32% of patients lost ≥20% body weight
Tirzepatide (SURMOUNT-1 trial - Zepbound 15mg):
- Average weight loss: 20.9% of body weight
- 77% of patients lost ≥15% body weight
- 63% of patients lost ≥20% body weight
Real-world example: A patient starting at 200 lbs on semaglutide: Expected loss ~30 lbs → 170 lbs. Same patient on tirzepatide: Expected loss ~42 lbs → 158 lbs.
Which One Should You Start With?
Start with Semaglutide if:
- You've never tried a GLP-1 medication before
- You want to minimize cost ($229 vs $299/month)
- Your insurance is more likely to cover it
