About Health Tools
How health tools are grouped
Pages are grouped by body-size screening, energy estimates, nutrient-factor arithmetic, exercise pace, and pregnancy-date estimation.
How to choose a health tool page
Use only a formula appropriate to the measurement and population; check required units and read the source and limitation section before interpreting any result.
Comparing similar health tools
BMI relates weight to height, RFM uses height/waist/sex, and waist-to-height ratio measures central adiposity. None is a direct diagnosis or complete body-composition assessment.
Common health tools workflows
Verify measurements and units, reproduce the example, calculate, read population limits, then discuss consequential results with a qualified professional.
Health Tools privacy notes
Health inputs are calculated in the browser and are not sent by these pages, but users should avoid exposing personal measurements through shared devices or clipboard history.
Health Tools limitations
The tools do not diagnose, treat, account for full medical history, or replace clinical measurement, ultrasound dating, laboratory testing, or individualized nutrition advice.
