1. What is TDEE Calculator Intermittent Fasting?

The TDEE (Total Daily Energy Expenditure) Calculator estimates your total daily calorie needs based on your Basal Metabolic Rate (BMR) and activity level. This calculator is specifically designed for those practicing intermittent fasting.

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 (unitless)

Explanation: The equation calculates your total daily energy expenditure by multiplying your basal metabolic rate with an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Accurate TDEE estimation is crucial for weight management, whether your goal is weight loss, maintenance, or muscle gain. For intermittent fasting practitioners, knowing your TDEE helps optimize fasting windows and meal planning.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity factor. All values must be valid (BMR > 0).

5. Frequently Asked Questions (FAQ)

Q1: Does intermittent fasting affect TDEE?
A: Intermittent fasting may temporarily affect TDEE due to changes in meal timing, but the fundamental calculation remains the same.

Q2: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict, which consider age, weight, height, and gender.

Q3: Should I adjust my TDEE for weight loss?
A: For weight loss, create a calorie deficit by consuming 300-500 calories less than your TDEE.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (±5kg/11lbs).

Q5: Does TDEE change with intermittent fasting?
A: While meal timing may affect energy expenditure slightly, the activity factor in the TDEE calculation accounts for your overall physical activity level.
