1. What is Daily Calorie Burn Rate?

The Daily Calorie Burn Rate represents your total daily energy expenditure (TDEE), which is the total number of calories your body burns in a day. It consists of your basal metabolic rate (BMR) plus calories burned through physical activity.

2. How Does the Calculator Work?

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

Where BMR is calculated as:

• For Men: \( BMR = 10 \times weight(kg) + 6.25 \times height(cm) - 5 \times age(years) + 5 \)
• For Women: \( BMR = 10 \times weight(kg) + 6.25 \times height(cm) - 5 \times age(years) - 161 \)

Activity Multipliers:

• Sedentary (little or no exercise): 1.2
• Light (light exercise 1-3 days/week): 1.375
• Moderate (moderate exercise 3-5 days/week): 1.55
• Active (hard exercise 6-7 days/week): 1.725
• Very Active (very hard exercise, physical job): 1.9

3. Importance of Daily Burn Calculation

Details: Knowing your daily calorie burn is essential for weight management, creating effective diet plans, and optimizing athletic performance. It helps determine appropriate calorie intake for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter accurate weight in kilograms, height in centimeters, age in years, select gender and appropriate activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculator?
A: The Mifflin-St Jeor Equation is considered one of the most accurate BMR formulas for the general population, but individual variations may occur.

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

Q4: How often should I recalculate my daily burn?
A: Recalculate every 4-6 weeks or whenever your weight changes by more than 5kg or your activity level significantly changes.

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