1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity. It's essential for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\ Level \) — Multiplier based on physical activity level

Activity Level Multipliers:

• Sedentary: 1.2 (little or no exercise)
• Lightly active: 1.375 (light exercise 1-3 days/week)
• Moderately active: 1.55 (moderate exercise 3-5 days/week)
• Very active: 1.725 (hard exercise 6-7 days/week)
• Extra active: 1.9 (very hard exercise, physical job)

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized nutrition and fitness plans.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine. For accurate results, use a reliable BMR calculator first.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism and activity patterns may affect accuracy.

Q3: Should I eat my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly or your activity level changes substantially.

Q5: Can TDEE change over time?
A: Yes, TDEE decreases with age and weight loss, and increases with muscle gain and increased activity.
