Terms of Use
FitBasis provides general education for adults. Calculators and guides are planning tools, not medical advice, diagnosis, treatment, or a promise of weight change.
Use the Site Safely
Use calculator results as estimates. Medical history, symptoms, medication, harmful restriction, clinician-supervised life stages, clinical diet limits, or complex health context should be handled with qualified professional guidance.
Source Notes and Limits
FitBasis cites official, public-health, and primary source families where possible. Source-backed framing does not turn a page into personalized care for one reader.
