How Caloric Needs Are Estimated
The Mifflin-St Jeor equation calculates Basal Metabolic Rate (BMR)—the energy required for vital organs to function at rest. Multiplying BMR by your physical activity multiplier provides an estimated Total Daily Energy Expenditure (TDEE).
Frequently Asked Questions
What factors influence daily calorie burn?

Is this calorie estimate exact?
No. Calorie calculators provide population-level estimates. Individual metabolic rates vary by up to 10-15% based on body composition, thyroid function, and lifestyle factors.
