How to Calculate Your Maintenance Calories
Your Total Daily Energy Expenditure (TDEE) is an estimation of how many calories you burn per day when exercise is taken into account. Knowing this number is the single most important factor when figuring out how to build muscle effectively or lose body fat sustainably.
This calculator is built using the universally accepted Mifflin-St Jeor equation. It first calculates your Basal Metabolic Rate (BMR)—the precise amount of energy your body uses just to keep your organs functioning while completely at rest. We multiply your BMR by your self-reported activity multiplier to generate your total output.
If your goal is to lose weight, experts generally recommend subtracting 300 to 500 calories from your TDEE result. To pack on muscle mass, try adding a 300 to 500 calorie surplus!
Frequently Asked Questions
How accurate is the Mifflin-St Jeor equation?
It is widely considered the most accurate mathematical formula available without utilizing clinical-grade metabolic laboratory testing to gauge individual metabolism.
Should I eat the exact number of calories every day?
No, small daily fluctuations in calorie intake are completely normal! TDEE is an average target meant to guide your overall weekly caloric trend.
