About TDEE.page
A modern, transparent, and privacy-first computational tool engineered to demystify human energy expenditure and evidence-based nutrition planning.
Our Mission & Purpose
Calculating daily caloric expenditure should not be obscured behind intrusive advertisements, mandatory email signups, paywalled macros, or hidden proprietary math.
TDEE.page was built to provide athletes, fitness enthusiasts, coaches, and health-conscious individuals with an authoritative, clutter-free utility. We combine peer-reviewed metabolic equations with transparent mathematical breakdowns and interactive data visualizations.
Scientific Foundations
Every calculation performed by our engine is grounded in established nutritional literature:
1. Mifflin-St Jeor Equation (1990)
Validated as a reliable general-population mathematical standard for estimating Resting Metabolic Rate (RMR).
2. Schofield Equations (1985 / FAO/WHO/UNU)
The international benchmark adopted by the United Nations and WHO spanning 6 age categories for global metabolic rate estimation.
3. Katch-McArdle & Cunningham Formulas
Scales energy demand directly from Lean Body Mass (LBM), providing superior metabolic precision for athletes and individuals with measured body composition.
4. Physical Activity Level (PAL) Multipliers
Calibrated according to the World Health Organization (WHO), Food and Agriculture Organization (FAO), and United Nations University (UNU) joint technical guidelines.
Core Guiding Principles
- ✓Privacy by Design: Zero health telemetry. All computations run in your local web browser. Your age, weight, and body metrics never touch external servers.
- ✓Full Mathematical Transparency: We show the exact formulas, intermediate steps, and proportional breakdowns rather than a mysterious black-box number.
- ✓Honest Scientific Nuance: We actively educate users on adaptive thermogenesis, NEAT downregulation, and the necessity of real-world scale calibration.
