FAQ

What is TDEE?

TDEE means Total Daily Energy Expenditure. It estimates how many calories you burn per day after your activity level is included.

What is BMR?

BMR means Basal Metabolic Rate. It estimates how many calories your body burns at rest.

Should I enter body fat percentage?

It is optional. If you know your body fat percentage, the calculator can use the Katch-McArdle formula based on estimated lean body mass. If you do not know it, leave the field blank.

Why is the result an estimate?

Real calorie needs vary with metabolism, training, hormones, sleep, food tracking accuracy and lifestyle. Use the number as a starting point and adjust with real-world progress.

Is this suitable for everyone?

No calculator replaces professional advice. Consult a qualified professional for pregnancy, illness, eating-disorder risk, medication, sports performance, or major weight changes.
