Straightforward answers about the product and the numbers.

FitCalc connects a guided Plan, preference-based Nutrition recommendations, focused calculators, and educational Articles, Guides, and Methodology. It is an educational planning system, not medical care.

No. Equations and inputs produce useful estimates, not laboratory measurements or guarantees. Use them as starting points and calibrate them against consistent real-world trends.

Plan connects estimated energy needs, calorie and macro targets, goal context, and a planning roadmap when applicable. The result depends on the information and preferences you provide.

No. Timeline projections are planning estimates. Actual change depends on adherence, activity, water and glycogen shifts, individual adaptation, and other factors described in the Methodology.

FitCalc Nutrition uses validated preferences, exclusions, dietary compatibility, category rules, and soft ranking to build recommendations from its catalog. It does not generate a medical meal plan.

Only according to your persistence choice. With permission, validated preference identifiers may be stored locally in your browser; otherwise they remain limited to the current session.

FitCalc estimates BMR using Mifflin–St Jeor and multiplies it by the activity level you select. The result is a maintenance starting point, not a direct measurement.

BMI compares weight with height squared and provides an adult screening reference. It does not distinguish fat mass from lean mass and is not a diagnosis.

The Body Fat Calculator uses sex-specific U.S. Navy circumference equations. Measurement technique affects the result, and the estimate is not equivalent to a laboratory assessment.

Yes. The clear-saved-data control removes supported persisted profile, Plan, Nutrition, and handoff state while leaving separate Analytics and newsletter choices unchanged. See Privacy for details.
