Educational tools

helsi provides arithmetic and population-based estimates for adults. Results are not medical advice, diagnoses, personalized nutrition prescriptions or training instructions. Read the applicability and limitations on each tool before interpreting a result.

Your decisions

Input accuracy, equipment suitability and the relevance of an equation to your circumstances affect the result. No specific health outcome, weight-change timeline or physical performance is promised. Seek individual professional support for clinical nutrition or medical needs.
