Mounjaro or Wegovy: The Definitive Comparison
Why This Decision Matters
Choosing between Mounjaro or Wegovy isn't just about brand names - it's about results. Both require significant commitment and investment, so choosing the more effective option from the start makes sense. Here's the evidence-based breakdown.
The Science: Mounjaro's Advantage
Mounjaro's dual mechanism:
• Activates GIP receptors: enhances metabolic function
• Activates GLP-1 receptors: reduces appetite, slows digestion
• Combined effect: more comprehensive weight loss
Wegovy's single mechanism:
• Activates GLP-1 receptors only
• Effective but limited to one pathway
• Good results, but not as powerful as dual-action
This scientific difference translates directly into better results with Mounjaro.
Clinical Trial Showdown
Mounjaro SURMOUNT trials:
• Participants lost up to 22.5% of body weight
• Average across doses: 15-22%
• Higher doses showed greatest effect
Wegovy STEP trials:
• Participants lost up to 15% of body weight
• Average across trials: 12-15%
• Consistent but lower than Mounjaro
The data clearly favours Mounjaro for maximum weight loss.
Real-World Results Comparison
What this means for actual patients:
18-stone patient choosing Mounjaro:
• Potential loss: 2.7-4 stone (17-25kg)
• Potential end weight: 14-15.3 stone
18-stone patient choosing Wegovy:
• Potential loss: 2.2-2.7 stone (14-17kg)

Mounjaro could mean an extra half stone or more lost.
