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 nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

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

Activity 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)
• Extremely 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 diet and exercise plans.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine. Ensure BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: What's 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 calculation?
A: It provides a good estimate, but individual variations in metabolism and activity patterns may affect accuracy.

Q3: Should I use TDEE for weight loss?
A: Yes, consuming 500 calories less than your TDEE typically results in about 1 pound of weight loss per week.

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.
