1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories you burn in a day, including basal metabolic rate (BMR) and activity. For weight loss, consuming 500 calories less than your TDEE typically results in about 0.5kg loss per week.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• \( weight \) — Weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The Mifflin-St Jeor equation calculates your basal metabolic rate (BMR), which is then multiplied by your activity level to determine TDEE.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for effective weight management. Consuming fewer calories than your TDEE creates a deficit leading to weight loss, while consuming more leads to weight gain.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, be honest about your activity level and measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories for weight loss?
A: A 500-calorie daily deficit typically results in about 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.

Q2: How accurate is this calculator?
A: It provides a good estimate for most women, but individual variations in metabolism may affect actual energy needs.

Q3: Should I eat below my BMR?
A: Generally no. Consuming fewer calories than your BMR can slow metabolism and cause nutrient deficiencies.

Q4: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.

Q5: What if I'm not losing weight at this calorie level?
A: You may need to adjust your calorie intake further or ensure you're tracking accurately. Consult a nutritionist if needed.
