1. What is Daily Calorie Burn?

Daily calorie burn represents the total number of calories your body expends in a day, comprising your basal metabolic rate (BMR) and calories burned through physical activity. Understanding this helps in weight management and fitness planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and activity multipliers:

\[ \text{BMR} = 10 \times \text{weight} + 6.25 \times \text{height} - 5 \times \text{age} + 5 \ (\text{male}) \] \[ \text{BMR} = 10 \times \text{weight} + 6.25 \times \text{height} - 5 \times \text{age} - 161 \ (\text{female}) \] \[ \text{Daily Burn} = \text{BMR} \times \text{Activity Multiplier} \]

Activity Multipliers:

Sedentary: 1.2 (little or no exercise)
Light: 1.375 (exercise 1-3 days/week)
Moderate: 1.55 (exercise 3-5 days/week)
Active: 1.725 (exercise 6-7 days/week)
Very Active: 1.9 (hard exercise daily)

3. Importance of Daily Burn Calculation

Details: Knowing your daily calorie expenditure is essential for weight management, athletic training, and maintaining overall health. It helps determine appropriate calorie intake for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter weight in kilograms, height in centimeters, age in years, select gender and activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How accurate is this calculation?
A: The Mifflin-St Jeor equation is considered the most accurate for BMR estimation in most populations, with accuracy around ±10%.

Q3: Should I eat below or above my daily burn?
A: For weight loss, consume 300-500 calories below daily burn. For maintenance, match your intake. For weight gain, consume 300-500 calories above.

Q4: How often should I recalculate my daily burn?
A: Recalculate every 4-6 weeks or after significant weight changes (±5 kg) or changes in activity level.

Q5: Does muscle mass affect calorie burn?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Individuals with higher muscle mass typically have higher BMR.
