1. What is TDEE?

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

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level (dimensionless)

Explanation: The equation multiplies your basal metabolic rate by an activity factor that accounts for your daily physical activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for effective weight management. It helps determine appropriate calorie intake for weight loss, maintenance, or gain goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level factor. BMR can be calculated using various formulas based on age, gender, weight, and height.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: TDEE calculations provide estimates. Individual variations in metabolism, NEAT (non-exercise activity thermogenesis), and other factors can affect actual energy expenditure.

Q2: Should I use sedentary or active factor?
A: Choose the factor that best represents your typical weekly activity level. Be honest about your exercise habits for accurate results.

Q3: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity levels change, or every few months to account for metabolic adaptations.

Q4: Can TDEE change with age?
A: Yes, TDEE typically decreases with age due to changes in metabolism, muscle mass, and activity levels.

Q5: Is TDEE the same for everyone of the same weight?
A: No, TDEE varies based on body composition, genetics, hormone levels, and individual metabolic rates.
