What it measures

In Tanita’s explanation, a comparison between basal metabolic rate (BMR) and age-group reference averages.

Required inputs

Device-specific body-composition estimates and the information used to estimate BMR.

How it was developed

The implementation and reference database depend on the device maker. The current source describes the feature, not a complete peer-reviewed validation.

Outcome associations

Independent outcome validation of the specific age display has not been established in this review.

Limitations

Do not confuse a scale’s metabolic age with a metabolomic laboratory clock, PhenoAge or a clinical diagnosis.

Can you calculate it yourself?

A device may calculate it, but proprietary reference values can prevent independent reproduction.

Commercial use

Tanita describes this feature in its body-composition documentation. No product profile is included in the initial six entries.
