How Projected Weight Loss Is Calculated

Projected weight loss represents the total amount of body weight you might lose over a specific period using Tirzepatide. The calculation uses a multiplicative model derived from SURMOUNT clinical trials to estimate your outcome.

Total Loss % = Base 15% × Dosage × Duration × Lifestyle × Age × Gender

Where:

  • Dosage: 2.5mg (0.7) to 15mg (1.15)
  • Duration: 3mo (0.4) to 18mo (1.2)
  • Lifestyle: Minimal (0.8) to Intensive (1.2)

First, we establish a base efficacy rate of 15% total body weight loss. Then, we multiply this base by factors for your dosage strength, treatment length, and lifestyle commitment. This method ensures your estimate reflects real-world clinical data rather than generic averages.

What Your Projected Weight Loss Means

This number shows the total pounds and percentage you might lose. It helps you set a realistic timeline for your health goals.

Significant Response: A result of 15% to 20% indicates an exceptional outcome. This is comparable to surgical results and often requires a high dose (10-15 mg) with intensive lifestyle changes.

Clinical Success: A loss between 10% and 14.9% meets FDA benchmarks for effective medication. This level of loss significantly reduces visceral fat and improves blood pressure.

Planning for Events: Use the "months to target" result to schedule weddings or surgeries. This ensures you reach a healthy weight before these important dates.

Track your actual weight weekly and adjust your inputs if progress slows down. Recalculating helps you stay accountable to your specific health journey.
