# Are weight and body fat supported in body payloads?

Body measurement data is supported in the `body` payload across all environments, including production.

You receive fields such as `weight_kg`, `height_cm`, `bodyfat_percentage`, `lean_mass_g`, `bone_mass_g`, and BMR **when the source provides them**.

Any field present and non-null in a sandbox or playground response is also supported in production.
