Measure consistently
Use current measurements and keep units consistent when using the macro tool. A change in measurement technique can change the result even when the underlying situation has not changed.

Guidance
Read ranges as context, not a diagnosis
Health ranges and screening categories are broad reference points. They do not account for every factor that can affect an individual person.
Use the result for education and planning
For symptoms, diagnosis, treatment, medication, pregnancy concerns, or individualized medical decisions, use an appropriate healthcare source rather than relying on a calculator result alone.
Understand this calculator
How to use it
Start with the values requested by the Macro tool and replace any sample numbers with figures from your actual situation. Build daily protein, carbohydrate and fat targets from a calorie target using flexible macro percentages. Keep every entry in the unit and time period shown beside the field, then review the highlighted result together with the supporting outputs.
What the results mean
The highlighted result is the main answer produced by the Macro calculation. The additional result cards provide context, components, ratios, costs, quantities, or comparison values that help explain why the primary result changed when you adjusted an input. Health categories are screening or planning context only and should not be read as a diagnosis, treatment recommendation, or individualized medical conclusion.
How the calculation works
The Macro tool applies the arithmetic or modeling relationship described by the requested inputs and supporting outputs. Build daily protein, carbohydrate and fat targets from a calorie target using flexible macro percentages. Keep units, rates, and time periods consistent so the result reflects the scenario you intended to model.
Example and practical context
Use one consistent set of measurements as a baseline. If you revisit the calculator later, measure under similar conditions so a change in the result is less likely to come from a different measurement method.
Results are estimates based on the values and assumptions entered. Review the Methodology and Calculator Disclaimer for important limitations.
