1. What is Total Daily Calorie Calculation?

The Total Daily Calorie Calculation estimates your daily energy needs based on your Basal Metabolic Rate (BMR) and activity level. It provides an estimate of how many calories you burn each day, known as Total Daily Energy Expenditure (TDEE).

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\_factor \) — Multiplier based on activity level

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 Calorie Calculation

Details: Knowing your TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level. For accurate results, use a recent BMR measurement or calculation.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using equations like Mifflin-St Jeor or Harris-Benedict, or measured through indirect calorimetry.

Q2: What if my activity varies day to day?
A: Choose the activity level that best represents your average weekly activity.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Adjust based on your results over time.

Q4: Should I adjust my calories for weight goals?
A: For weight loss, subtract 250-500 kcal/day; for gain, add 250-500 kcal/day from your TDEE.

Q5: How often should I recalculate?
A: Recalculate when your weight changes significantly (±10 lbs) or your activity level changes.
