Nutrition Calculators
9 Nutrition calculators with educational summaries for clinical reference.
What this collection covers
Nutrition tools include body-size estimates, body-composition proxies, growth references, energy calculations, and selected nutrition-related risk assessments. The pages explain which measures are screening tools and which require age, sex, or population-specific references.
How to choose a tool
Begin with the population and purpose: adult screening, pediatric growth tracking, energy estimation, body-surface area, or a metabolic risk discussion. Record the measurement method and units, and avoid treating a population reference as a diagnosis.
Safe interpretation
Weight-based estimates can misclassify athletes, older adults, people with edema, amputations, pregnancy, or altered body composition. Use clinical history, dietetic assessment, growth trajectory, and relevant laboratory or functional data when making care decisions.
