Medication
Semaglutide and tirzepatide use different mechanisms and study-based outcome ranges. Individual response varies, and neither profile predicts your result.

How to Use This Calculator
Quick guidance for choosing your inputs and interpreting your estimate with realistic expectations.
Activity Level
This creates a discussion prompt for your care plan. It does not change the medication projection in this calculator.
Protein Goal
Your entered goal appears in the coaching notes. Ask your provider what intake fits your health history and care plan.
Water Goal
Your entered goal appears in the coaching notes. Fluid needs vary, so ask your provider about a suitable target.
Weeks on Medication
Early weeks can be slower. Progress often changes as dosing increases over time, so this input helps make your estimate more realistic.
How to Read Results
Results are estimates, not guarantees. You will see a range instead of a fixed promise, and milestones help map the likely path forward.
Age, sex, activity, protein, and water inputs support discussion prompts. They do not change the study-informed medication range. Individual results depend on many factors this calculator does not measure.
