Quick Answer
How Many Calories Does Brisk Walking Burn?
Brisk walking at around 4 mph burns roughly 300–400 calories an hour for most adults — about 276 calories for a 70 kg person on a 45-minute brisk walk. Your own number rises with body weight and walking time and falls if you are lighter or out for less. Enter your weight and time above for an exact figure, plus the steps, distance and weekly total.
What Counts as Brisk Walking
Brisk walking sits at about 4 mph — a purposeful pace where you can still talk but could not comfortably sing. In energy terms that lands at roughly MET 5.0, noticeably above the average everyday stroll of about 3 mph that most people default to. The line between "walking" and "brisk walking" is really about effort: if your breathing has picked up and you are covering a mile in around fifteen minutes rather than twenty, you are in brisk territory. That higher intensity is exactly what makes the pace worth singling out, because the calorie cost per minute climbs with it.
How Much More Brisk Walking Burns
The premium shows up clearly in a side-by-side. A 45-minute brisk walk for a 70 kg adult costs about 276 calories, against roughly 193 calories for the same 45 minutes at an average pace — a meaningful difference for no extra time on your feet. That gap is the per-minute premium of intensity, and because it repeats every session it compounds across a week: five brisk walks bank far more than five easy ones. The table below shows the same 45-minute brisk walk across a range of body weights, since a heavier body burns more energy to cover the same ground.
45-Minute Brisk Walk, by Body Weight
| Body weight | Calories in 45 minutes |
|---|---|
| 55 kg / 121 lbs | ~217 kcal |
| 70 kg / 154 lbs | ~276 kcal |
| 85 kg / 187 lbs | ~335 kcal |
| 100 kg / 220 lbs | ~394 kcal |

Brisk Walking and Weight Loss
Five 45-minute brisk walks a week for our 70 kg example come to around 1,380 calories — a steady weekly burn that supports gradual change over months. It is worth being honest about two things, though. The figure here is the gross burn, and a slice of it is the baseline metabolism you would spend sitting anyway, so the true "extra" is a little smaller. And weight loss ultimately follows your overall calorie balance: a brisk walk only moves the needle if it is not cancelled out by eating more to compensate. Pairing the walk with a small dietary trim is what makes the brisk premium actually pay off.
To turn this single walk into a full timeline, use the Walking Weight Loss Calculator; to convert your walk into a daily step target, the Steps to Weight Loss Calculator; and to size the eating side, the Calorie Deficit Calculator. A calorie deficit is only appropriate if you are above a healthy weight. These are general estimates, not medical advice.
MET values are from the Ainsworth Compendium of Physical Activities (2011), walking codes 17010–17070. Calories use 1 MET = 1.05 kcal/kg/hr; figures assume flat, level-surface walking. A 2024 revision — the Adult Compendium of Physical Activities (PMID 38242596) — has since updated some MET values; these figures use the established 2011 measured values for consistency across the site.
