TheMetabolic Baseline Protocol
Your metabolism is the internal furnace that powers your existence. Understanding your BMR—the calories required just to stay alive at rest—is the foundation of any nutritional strategy. Our engine layers your physical activity level on top of this baseline to calculate your TDEE, the true 'Maintenance' number that dictates your weight-management trajectory.
EnergyExpenditure Logic
The Mifflin-St Jeor Algorithm
Our engine utilizes the Mifflin-St Jeor equation, currently regarded as the most accurate clinical standard for healthy adults. It factors in biomass, vertical stature, chronological age, and biological sex to find your resting metabolic baseline with high fidelity.
The NEAT Variable
Exercise is only a small part of your TDEE. Non-Exercise Activity Thermogenesis (NEAT)—the calories burned through daily movement like walking or standing—is often the larger variable. Our calculator provides a granular activity-multiplier matrix to capture this metabolic complexity.
