1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values, which represent the intensity of an activity compared to resting metabolism.

2. How Does the Calculator Work?

The calculator uses the calories burned equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (activity intensity)
• \( weight \) — Body weight in kilograms
• \( time \) — Duration of activity in minutes

Explanation: The equation calculates calories burned by multiplying the activity's MET value by your weight and the duration of the activity.

3. Importance of Calories Calculation

Details: Knowing calories burned during exercise helps with weight management, creating effective workout plans, and achieving fitness goals.

4. Using the Calculator

Tips: Enter MET value (3.5-8 for weight training), your weight in kg, and exercise duration in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for weight training?
A: Moderate weight training is about 4.5 METs, vigorous training about 6 METs, and circuit training about 8 METs.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism and exercise intensity affect actual calories burned.

Q3: Should I eat back all calories burned?
A: For weight loss, it's generally recommended to eat back only a portion (50-75%) of estimated exercise calories.

Q4: Does muscle mass affect calories burned?
A: Yes, more muscle mass increases basal metabolic rate and calories burned during exercise.

Q5: How often should I recalculate?
A: Recalculate whenever your weight changes significantly or you change your workout intensity.
