How to Calculate Calories Burned During Activities

Calculating the calories burned during various activities involves considering several factors, including your weight, the type of activity, and its duration. This calculation provides an estimate of energy expenditure during your chosen activity.

Calories Burned Formula

The formula used to calculate calories burned during activities is:

$$\text{Calories Burned} = \frac{\text{MET} \times 3.5 \times \text{Weight (kg)} \times \text{Duration (minutes)}}{200}$$

Where:

• MET (Metabolic Equivalent of Task): A measure of activity intensity relative to resting metabolism
• 3.5: A constant representing the average resting oxygen consumption in mL/kg/min
• Weight: Your body weight in kilograms
• Duration: The time spent on the activity in minutes
• 200: A conversion factor to adjust the result to calories

Calculation Steps

1. Determine your weight in kilograms.
2. Select the appropriate MET value based on the activity.
3. Input the duration of your activity in minutes.
4. Apply the formula to calculate calories burned.

Example Calculation

Let's calculate the calories burned for a person with the following details:

• Weight: 70 kg
• Activity: Jogging (MET = 7.0)
• Duration: 30 minutes

Step 1: Apply the formula

$$\begin{align} \text{Calories Burned} &= \frac{7.0 \times 3.5 \times 70 \times 30}{200} \\ &= \frac{5145}{200} \\ &= 257.25 \text{ calories} \end{align}$$

Therefore, this person burns approximately 257 calories during their 30-minute jogging session.
