Burn check

Choose your exercise type, duration, and weight, then select what you ate to 'earn' the workout for a net calorie verdict.

What this means

This tool uses MET values to estimate calorie burn from exercise type, duration, and body weight, then subtracts any post-workout food to show the net picture.

Formula used

Calories burned = MET × body weight (kg) × duration (hours). Net = burned − eaten back.

Worked example

45 minutes of running at 80kg burns roughly 588 kcal. Adding a big snack (400 kcal) leaves a net burn of 188 kcal.

Common questions

How accurate is the calorie estimate?
MET-based estimates are population averages with significant individual variation. Fitness level, efficiency, and actual effort all affect the real figure. Use this as a rough order of magnitude, not a precise measurement.

Does a negative net mean the exercise was pointless?
No. Exercise has cardiovascular, strength, mood, and metabolic benefits that are independent of calorie balance. The net figure just helps you understand the energy picture, not the full value of the session.

Plain-English summary

Enter your session details to find out how many calories you burned and whether the post-workout eating changed the picture.

This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.

Disclaimer: MET-based calorie estimates have significant individual variation. This is a rough guide, not a clinical measurement or dietary advice. If you have a medical condition or eating-related concerns, use qualified advice.
