1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including basal metabolic rate (BMR) and activity level. It's crucial 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 helps determine your daily calorie needs for weight maintenance, loss, or gain. It's fundamental for creating personalized nutrition plans.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For accurate results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How is TDEE different from BMR?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly (±10 lbs) or your activity level changes substantially.

Q3: Are the activity factors accurate for everyone?
A: They're estimates. Individual variations exist based on metabolism, body composition, and exercise intensity.

Q4: Should I eat exactly my TDEE to maintain weight?
A: TDEE is an estimate. Monitor your weight over time and adjust as needed.

Q5: How do I use TDEE for weight loss?
A: Consume 300-500 calories below your TDEE for gradual weight loss (0.5-1 lb/week).
