Biography

Priya Nandakumar is the editor for health and biometrics at Calculator Archive. She is a Registered Dietitian (RD) with an M.S. in Clinical Nutrition, and her work centers on the equations our health tools actually run: Mifflin-St Jeor, Harris-Benedict, and Katch-McArdle for energy expenditure, and the WHO and CDC thresholds our BMI tools publish.

She writes and reviews the health guides with one rule: name the equation, name the source, and show the arithmetic. Because health content is YMYL, every page she owns carries a plain-language reminder that the output is an estimate for education, not medical advice, and links out to the primary source — who.int, cdc.gov, or the NHS — behind each published figure.

Editorial Focus

• Basal metabolic rate and total daily energy expenditure
• Mifflin-St Jeor, Harris-Benedict, and Katch-McArdle equations
• Activity multipliers and energy-balance arithmetic
• WHO and CDC weight-classification thresholds
