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. For weight loss, women typically aim for a 300-500 calorie deficit below their TDEE.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and multiplies by activity factor:

Where Activity Factor is:

• 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 create an effective weight loss plan. A 500-calorie daily deficit typically leads to about 0.5kg (1lb) of weight loss per week.

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.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculator specific to women?
A: Women generally have lower BMR than men due to differences in body composition. This calculator uses the female-specific Mifflin-St Jeor equation.

Q2: How accurate is this calculator?
A: It provides a good estimate, but individual variations exist. For more accuracy, consider body composition testing.

Q3: Should I eat below my BMR for weight loss?
A: No, eating below BMR can slow metabolism. Aim for a moderate deficit below TDEE (typically 300-500 calories).

Q4: How often should I recalculate my TDEE?
A: Recalculate every 5-10kg of weight loss, as your BMR decreases with weight loss.

Q5: What if I'm not losing weight at the suggested calories?
A: You may need to adjust your activity factor or calorie intake. Metabolic adaptation can occur with prolonged dieting.
