Frequently Asked Questions
What is TDEE (Total Daily Energy Expenditure)?
TDEE is the total number of calories you burn in a day, including your Basal Metabolic Rate (BMR) plus calories burned through physical activity, exercise, and daily movements. It represents your complete daily energy expenditure and is essential for determining your daily calorie needs.
How is TDEE calculated?
TDEE is calculated by multiplying your BMR (calculated using the Mifflin-St Jeor equation) by an activity factor: Sedentary (1.2), Lightly active (1.375), Moderately active (1.55), Very active (1.725), or Extremely active (1.9). The BMR accounts for calories needed at rest, while the activity factor accounts for exercise and daily movement.
How do I use TDEE for weight loss?
For weight loss, create a calorie deficit by consuming 300-500 calories less than your TDEE daily. This typically results in 0.5-1 pound of weight loss per week. For faster weight loss, you can create a larger deficit, but never go below your BMR for healthy and sustainable weight loss.
How do I use TDEE for muscle gain?
For muscle gain, create a calorie surplus by consuming 200-500 calories more than your TDEE daily. Combine this with resistance training and adequate protein intake (0.8-1g per pound of body weight) for optimal muscle growth while minimizing fat gain.
How accurate is the TDEE calculator?
TDEE calculators provide estimates with ±10-15% accuracy for most people. Individual factors like genetics, muscle mass, metabolic efficiency, and health conditions can affect actual energy expenditure. Use the calculator as a starting point and adjust based on real-world results over 2-4 weeks.
What activity level should I choose?
Choose based on your weekly exercise routine: Sedentary (little/no exercise, desk job), Lightly active (light exercise 1-3 days/week), Moderately active (moderate exercise 3-5 days/week), Very active (hard exercise 6-7 days/week), or Extremely active (very hard exercise, physical job, or training twice daily).
Should I recalculate my TDEE regularly?
Yes, recalculate your TDEE every 4-6 weeks or when there are significant changes in weight (more than 5 pounds), activity level, or body composition. As you lose or gain weight, your BMR changes, which affects your TDEE.
Is this TDEE calculator free and private?
Yes, our TDEE calculator is completely free with no registration required. All calculations are performed locally in your browser using JavaScript, ensuring complete privacy protection. No personal data is transmitted to or stored on our servers.
