What does this mean?
This is just your baseline — the calories your body burns doing nothing at all. It does NOT include walking, exercise or daily activity. Use the Calorie Calculator to add your activity level and find your total daily calorie needs (TDEE).
For reference purposes only. This calculator provides a general estimate based on standard formulas and is not a medical diagnosis. It does not account for every individual factor (medical conditions, medications, pregnancy, body composition, etc.). Please consult a qualified doctor, dietitian or coach before making any health, nutrition or fitness decisions.
These estimates are general adult guidance, not a diagnosis or a nutrition plan for a growing child. Discuss individual needs with a qualified clinician or dietitian.
