1. What is TDEE for Women?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your basal metabolic rate (BMR) and activity level. It's crucial for weight management, whether your goal is weight loss, maintenance, or gain.

2. How Does the Calculator Work?

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

Where:

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

The Mifflin-St Jeor Equation for women: \[ BMR = (10 \times weight\ in\ kg) + (6.25 \times height\ in\ cm) - (5 \times age) - 161 \]

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 create personalized nutrition plans. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. For maintenance, match your intake to your TDEE.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is TDEE different for women than men?
A: Women generally have lower TDEE due to typically lower muscle mass and different hormonal profiles affecting metabolism.

Q2: How accurate is this calculator?
A: It provides a good estimate but individual variations exist. For precise measurements, metabolic testing is recommended.

Q3: Should I use this during pregnancy?
A: No, pregnancy significantly changes energy needs. Consult your healthcare provider for guidance.

Q4: How often should I recalculate my TDEE?
A: Recalculate after significant weight changes (±5kg) or activity level changes.

Q5: Why does TDEE decrease with age?
A: Metabolism slows with age due to decreasing muscle mass and hormonal changes.
