1. What is the Calorie Burn Equation?

The calorie burn equation estimates total calories burned during physical activity based on MET (Metabolic Equivalent of Task) values, your weight, and exercise duration. It provides a way to quantify energy expenditure across different activities.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{MET} \) — Metabolic Equivalent of Task (intensity measure)
• \( \text{weight\_kg} \) — Your body weight in kilograms
• \( \text{minutes} \) — Duration of each exercise
• 3.5 — Oxygen consumption at rest (mL/kg/min)

Explanation: The equation calculates calories burned for each exercise and sums them up for the total energy expenditure.

3. Importance of MET Values

Details: MET values represent exercise intensity. Common values: Walking (3-5), Running (8-12), Cycling (6-10), Swimming (5-8). Higher MET means more calories burned per minute.

4. Using the Calculator

Tips: Enter your weight in kg, then add each exercise with its MET value and duration. You can add multiple exercises to calculate total calories burned in a workout session.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find MET values for exercises?
A: MET values are available in exercise databases like the Compendium of Physical Activities. Many fitness trackers also use MET values.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual factors like fitness level and body composition can affect actual calorie burn.

Q3: Should I use kg or pounds?
A: The calculator uses kg. To convert from pounds: weight_kg = weight_lbs / 2.205.

Q4: Does this account for afterburn effect?
A: No, this only calculates calories burned during the exercise. Some intense exercises continue burning calories afterward.

Q5: Can I use this for weight loss planning?
A: Yes, it can help estimate exercise contribution to calorie deficit, but nutrition is equally important for weight loss.
