Calories to Walk Off a Food Calculator
See how far and how long you would need to walk to burn off a food, from its calories, your body weight and your walking pace.
How it works
kcal/min = MET × 3.5 × weight(kg) ÷ 200 · Minutes = food kcal ÷ kcal/min · Distance = speed × minutes ÷ 60
Walking burns energy at a rate set by your pace (its MET value) and your body weight, using the standard MET equation. Dividing a food’s calories by that per-minute burn tells you how long you would need to walk to offset it, and multiplying by your walking speed gives the distance. It is a fun, motivating way to picture a food’s energy — but calories are only part of nutrition, and you cannot out-walk a poor diet, so use it for perspective rather than as a rule to earn food.
Worked example
A 250 kcal snack for a 70 kg person walking at a moderate 5 km/h (MET 3.5): burn = 3.5 × 3.5 × 70 ÷ 200 ≈ 4.3 kcal/min, so 250 ÷ 4.3 ≈ 58 minutes, covering about 4.9 km — roughly 6,800 steps.
Frequently asked questions
Why does body weight change the answer?
Heavier bodies burn more energy to move the same distance, so a heavier person walks off a food faster (in less time and distance) than a lighter one at the same pace. That is why the calculation scales the burn rate by your weight.
Is walking off calories a good weight-loss strategy?
Walking is excellent for health and adds to your daily burn, but it is hard to out-exercise excess intake — a short walk offsets only a modest snack. Sustainable weight change comes mainly from overall diet, with activity as a valuable complement.
How accurate is the step estimate?
It assumes about 1,400 steps per kilometre, which suits an average adult stride. Taller people take fewer, longer steps and shorter people take more, so treat the step count as a ballpark rather than an exact figure.
