Frequently Asked Questions
Is the result an exact personal requirement?
It is a reference or model-based estimate. Actual needs depend on the person, the measurement method and the situation; a planning estimate should not be treated as a prescribed intake.
Why can another nutrition calculator differ?
Different tools use different reference tables, equations, ingredient densities or activity assumptions. Compare those choices as well as the input amounts.
