Versioned calculationFormula v1.0.0
Method
Apply the entered percentage and duration without importing trial efficacy.
Important boundary
Actual treatment response is nonlinear and individualized.
Enter a starting pointUse the labeled field and matching unit.
Choose your own assumptionThe calculator applies the displayed method at full precision.
Treat output as a scenarioKeep the stated boundary beside the result.
Interpretation
The primary value follows directly from the entered percentage.
The weekly value is only an arithmetic average.
No efficacy, dose, adherence, or safety prediction is made.

Recorded method
Verify percentage arithmetic, negative/no-change branches, unit parity, and absence of drug-efficacy defaults.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- No medicine, dose, diagnosis, adherence, or trial response is modeled.
- Does not predict plateaus, regain, side effects, or body composition.
- Not a treatment target.
- User assumption controls the result.

| Case | Inputs | Expected result |
|---|---|---|
| ten percent scenario | Starting weight: 100 kg; User-entered assumed weight change: 10 percent; Scenario duration: 52 number | Projected scenario weight: 90 kg; Scenario weight change: 10 kg; Arithmetic average per week: 0.1923076923 kg/week; classification: loss-scenario (allowed numeric tolerance: 0.001) |

What the GLP-1 Weight Scenario Projector calculates
Convert a user-entered percentage weight-change assumption into projected weight and simple average weekly change.
The tool avoids presenting trial averages as a personal outcome forecast.
Start with the Health calculators hub when a neighboring workflow better matches the question.
How to use the GLP-1 Weight Scenario Projector
- Enter starting weight.
- Enter an explicitly chosen scenario percentage.
- Choose a duration for arithmetic averaging.
- Compare multiple scenarios rather than treating one as expected.
Continue with the Protein Calculator. Plan protein separately from medicine decisions.
Formula, variables and calculation order
projected weight = starting weight x (1 - assumed change / 100).
Inputs are validated and normalized before the calculation. Working precision is retained until display rounding.
For a separate method, open the TDEE Calculator. Estimate whole-day energy expenditure.
Worked example and boundary check
Worked example
100 kg with a user-entered 10% change gives a 90 kg scenario and 10 kg arithmetic change.
Boundary check
A weekly average does not mean actual change will be linear.
How to interpret the result
Use the output for sensitivity planning only.
- No medicine, dose, diagnosis, adherence, or trial response is modeled.
- Does not predict plateaus, regain, side effects, or body composition.
- Not a treatment target.
- User assumption controls the result.
Compare the result with the Body Fat Calculator. Estimate body composition with a named method.
Frequently asked questions
