About

Priya covers body composition, macro tracking, and everyday health screening tools. She is careful to flag limitations — calculators are meant to inform, not diagnose — and links every tool back to peer-reviewed sources.

She spent five years in a hospital outpatient nutrition clinic before moving into consumer health writing.
