Estimates based on MET values and your body weight; actual burn varies with intensity, fitness, and terrain. General wellness info — eating should be enjoyable, and exercise is about more than burning off food.

How it works

The calculator takes the calories in your chosen food and works out how long each activity would take to burn that many calories for someone your weight, using standard MET (metabolic equivalent) values. Heavier people burn a little more per minute, so the time is personalized to you.

It’s a fun, eye-opening way to picture energy balance — not a rule that you must "earn" every bite.

Walking vs running vs cycling

Running burns the most calories per minute, then cycling, then walking — so the same food takes far longer to walk off than to run off. But the best activity is the one you’ll actually do: a longer walk you enjoy beats a hard run you dread and skip.

A healthier way to think about it

Exercise has huge benefits beyond burning calories, and food is about more than fuel. Use this as motivation to move, not as punishment for eating. If you’re managing weight, your overall daily calories and activity matter far more than offsetting any single food.

Frequently asked questions

How long does it take to walk off a slice of pizza?

A ~285-calorie slice takes most people roughly 60–75 minutes of brisk walking, or about 30 minutes of running — the exact time depends on your weight and pace.

Is it accurate?

It’s a solid estimate based on MET values and your body weight. Real burn varies with intensity, fitness, and terrain, so treat the numbers as a ballpark.

Should I exercise to “burn off” food?

It’s fine as motivation, but try not to treat exercise as punishment. Movement is valuable on its own, and overall habits matter more than any single food.
