What is the most accurate TDEE method?
The most accurate way to determine Total Daily Energy Expenditure (TDEE) is through direct or indirect calorimetry testing performed in a specialized human performance laboratory, which measures actual oxygen consumption and carbon dioxide production. For calculated estimates, the most reliable method involves multiplying an accurately measured or calculated Basal Metabolic Rate—using the Mifflin-St Jeor equation—by a precisely tracked activity factor that accounts for exercise activity, the thermic effect of food, and non-exercise activity thermogenesis. Wearable fitness technology and diligent daily calorie-tracking logs can further refine these mathematical estimations over time.
