1. What is the Calories Burned Calculator?

The Calories Burned Calculator estimates the number of calories burned during physical activity based on your Basal Metabolic Rate (BMR), activity level, and duration of activity. It helps in weight management and fitness planning.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{BMR} \) — Basal Metabolic Rate (kcal/day)
• \( \text{Activity Multiplier} \) — Physical activity level factor
• \( \text{Time} \) — Duration of activity (hours)

Activity Multipliers:

• 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 Burned Calculation

Details: Understanding calories burned is essential for weight management, fitness goal setting, and creating effective exercise and nutrition plans. It helps maintain energy balance for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter your BMR in kcal/day, select appropriate activity multiplier based on your exercise level, and input the duration of activity 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. You can calculate it using various formulas like Harris-Benedict or Mifflin-St Jeor equations.

Q2: How accurate is this calculation?
A: This provides a reasonable estimate, but individual factors like metabolism, body composition, and exercise intensity can affect actual calories burned.

Q3: Should I use this for weight loss planning?
A: Yes, this calculator helps estimate energy expenditure, which is useful for creating calorie deficit plans for weight loss.

Q4: What if I have multiple activities in a day?
A: Calculate each activity separately and sum the results, or use an average activity multiplier for the entire day.

Q5: Does this account for different types of exercise?
A: The activity multiplier provides a general estimate. For specific exercises, more detailed calculators may provide better accuracy.
