FAQs
What does TDEE mean?
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns each day based on your metabolic rate and activity level.
How is TDEE calculated?
It uses the Mifflin-St Jeor equation, which factors in your age, gender, height, weight, and activity level to compute caloric needs.
Is this calculator accurate?
Yes. It uses evidence-based formulas widely accepted by dietitians and fitness professionals.
Can I use TDEE for weight loss?
Yes. Reduce your TDEE by 15–25% to enter a safe caloric deficit for fat loss.
Can I gain weight using TDEE?
Yes. Add 10–15% more calories than your TDEE to support muscle gain or healthy weight gain.
What activity level should I choose?
Choose based on your daily routine, including job type and exercise frequency (e.g., Extra Active = manual labor or training 6–7 days/week).
Is this suitable for both genders?
Yes. The calculator adjusts values based on your gender input.
Does it support both unit systems?
Yes. Easily switch between Metric and Imperial systems as needed.
Can I recalculate quickly?
Yes. Modify any input and click Calculate again for an instant update.
