Fat Burning Calculator

The Fat Burning Calculator is a practical online tool designed to help you estimate how many calories and grams of fat you burn during physical activity. Whether you’re walking, running, cycling, swimming, or working out at the gym, this calculator gives you an instant breakdown of your fat-burning potential. It also shows how many sessions and days it will take to achieve your fat loss goals.

This user-friendly calculator is perfect for fitness enthusiasts, athletes, or anyone aiming to lose weight efficiently and scientifically.

How the Fat Burning Calculator Works

The calculator uses MET values (Metabolic Equivalent of Task) to estimate calories burned. Every physical activity has a MET score representing its energy cost. The formula applied is:

Calories Burned = MET × Weight (kg) × Duration (hours)

Since 1 gram of fat equals approximately 9 kcal, the calculator can also estimate grams of fat burned. It then determines how many sessions you’ll need to reach your desired fat loss goal.

Practical Example

Let’s walk through an example:

John, weighing 75 kg, decides to start running (8 km/h) for 45 minutes daily. His goal is to lose 5 kg of fat.

When John enters these values:

• Weight: 75 kg
• Activity: Running
• Duration: 45 minutes
• Goal: 5 kg

The calculator estimates:

• Calories burned per session: ~450 kcal
• Fat burned per session: ~50 g
• Sessions needed: ~100 sessions
• Days to goal: ~100 days

This gives John a clear, achievable plan — if he runs 45 minutes daily, he could lose 5 kg in about 100 days.
