1. What is Total Daily Energy Expenditure?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate and 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)
• \( Activity\ Factor \) — Multiplier based on activity level (1.2-2.0)

Activity Levels:

• Sedentary (1.2): Little to 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 helps in creating effective weight loss, maintenance, or muscle gain plans by determining appropriate calorie intake levels.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine and daily activity patterns.

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 calculation?
A: It provides a good estimate, but individual variations in metabolism and activity can 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 every 10-15 pounds of weight change or if your activity level significantly changes.

Q5: Can TDEE change throughout life?
A: Yes, TDEE generally decreases with age due to changes in metabolism and activity levels.
