Frequently Asked Questions

What is TDEE?

TDEE stands for Total Daily Energy Expenditure—the number of calories your body burns each day based on your BMR and activity level.

How accurate is this calculator?

It provides a good estimate using the Mifflin-St Jeor formula, one of the most validated methods in nutrition science.

Can I use TDEE for weight loss?

Yes. Subtract 500–700 calories from your TDEE to aim for ~1-1.5 lbs of fat loss per week.

What's the difference between BMR and TDEE?

BMR is your resting calorie burn. TDEE includes daily activity and exercise.
