1. What is the Calories Burn Calculator?

The Calories Burn Calculator estimates total daily calorie expenditure including physical activity. It calculates calories burned based on basal metabolic rate (BMR), activity level, and time duration.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( Activity Factor \) — Multiplier based on activity level
• \( Time \) — Duration in hours

Activity Factors:

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

3. Importance of Calories Burn Calculation

Details: Understanding daily calorie expenditure is crucial for weight management, fitness planning, and maintaining energy balance. It helps in setting appropriate calorie intake goals for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter your BMR in kcal/day, select appropriate activity factor based on your exercise level, and input time duration in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how do I calculate it?
A: BMR (Basal Metabolic Rate) is the number of calories your body burns at rest. It can be calculated using formulas like Harris-Benedict or Mifflin-St Jeor equations based on age, gender, weight, and height.

Q2: How accurate is this calculation?
A: This provides a reasonable estimate for most people, but individual variations in metabolism, body composition, and exercise intensity can affect accuracy.

Q3: Should I use this for weight loss planning?
A: Yes, this calculator helps estimate your daily energy expenditure, which is essential for creating a calorie deficit for weight loss or surplus for weight gain.

Q4: How often should I recalculate my calories burned?
A: Recalculate whenever your weight changes significantly, activity level changes, or every few months to account for metabolic adaptations.

Q5: Can this calculator be used for specific exercises?
A: This calculator provides total daily estimates. For specific exercise calorie burn, dedicated exercise calculators that consider exercise type and intensity are more appropriate.
