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 a crucial metric for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

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

Activity Factors:

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

3. Importance of TDEE Calculation

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg/10lbs) or your activity level changes substantially.

Q2: What's the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q3: How accurate are TDEE calculators?
A: They provide good estimates but individual variations exist. Monitor your progress and adjust as needed.

Q4: Should I use TDEE for weight loss?
A: Yes, creating a calorie deficit of 300-500 calories below your TDEE is a safe and effective weight loss strategy.

Q5: Do activity factors account for all types of exercise?
A: They provide general estimates. For precise calculations, consider tracking specific exercise calories separately.
