TDEE Calculator: Find Your Total Daily Energy Expenditure

Thanks, appreciated!

Hello Jackie, it's great to hear from you. Our calculator employs the Mifflin-St Jeor Equation, the Katch-McArdle Equation, and the Revised Harris-Benedict Equation to calculate BMR and TDEE. The Mifflin-St Jeor Formula is often considered the most accurate because of its thorough approach, taking into account weight, height, age, and gender. This formula's accuracy has been validated in recent studies and is found to be more precise across diverse populations. While the Katch-McArdle and Harris-Benedict formulas are also used, the Mifflin-St Jeor stands out for its consistency and reliability in estimating metabolic rates.

Hey Rose, the calculator, using the Mifflin-St Jeor Equation, provides an estimate with a 10% accuracy range of the Resting Metabolic Rate (RMR), it's important for individuals to consider this margin when using it for precise dietary and exercise planning. This tool offers a solid starting point, but individuals should monitor their body's response to dietary and exercise changes and adjust accordingly. Tracking progress over time and making incremental adjustments based on real-world outcomes is key to compensating for this margin of error and achieving more personalized and effective results.

Hello Shyam Kumar, great question. our calculator adjusts the estimated daily caloric needs by integrating an individual's self-reported activity level, which ranges from sedentary to athlete-level exercise. This inclusion is crucial for accurately determining the Total Daily Energy Expenditure (TDEE). The adjustment reflects the varying caloric requirements based on the extent of physical activity, ensuring that the calculated TDEE aligns more closely with an individual's actual energy expenditure. This approach enhances the accuracy of the TDEE estimation, making it a more tailored tool for individuals with diverse lifestyle and exercise habits.
