How Calorie Calculation Works
This calculator estimates your calorie needs using multiple equations: Mifflin-St Jeor, Harris-Benedict, and Katch-McArdle (if body fat is known). These formulas estimate your Basal Metabolic Rate (BMR), the number of calories your body burns at rest.
Total Daily Energy Expenditure (TDEE) is calculated by multiplying BMR by an activity factor. Based on your goal, the tool adjusts calories for weight loss (500-1000 deficit), maintenance, or gain.
FAQ
- What is BMR? Basal Metabolic Rate is how many calories your body needs to stay alive at rest.
- What is TDEE? Total Daily Energy Expenditure is your full daily calorie burn including activity.
- How accurate is this? These are estimations. Individual variations can apply.
