Metabolic Age / BMR Comparison

A future comparison view that will explain what a metabolic-age score can and cannot tell you.

Instrument

Interactive implementation in progress.

Ascendant tools are educational planning instruments for adults. They do not diagnose, prescribe or replace licensed medical care.

How it will work

The comparison will explain why solving a resting-energy equation backwards reproduces chronological age, and will only compare a measured resting energy figure against the equation's prediction — never output an age number.

What this tool will do

Explain what a metabolic-age score cannot tell you
Compare measured against predicted resting energy
Name indirect calorimetry as the measurement method

What this tool will not do

Output a metabolic age number
Compare a reader to an unlicensed reference dataset
Grade a metabolism as fast or slow
