Validated equations and physiological evidence
Your Total Daily Energy Expenditure (TDEE) represents the total amount of energy (in kilocalories) your body consumes over a 24-hour period. Energy balance dictates weight changes: consuming fewer calories than your TDEE produces a fat-loss deficit, while consuming more produces a caloric surplus for muscle building.
Adopted by the Academy of Nutrition and Dietetics as the gold standard equation for general populations. Standard error is within ±10%.
Calculates BMR directly from Lean Body Mass (LBM = Weight × [1 - Fat %]). Eliminates sex differences by isolating metabolically active tissue.
