Running burns more fat than walking for weight loss in the same time. It uses roughly twice the calories as brisk walking over equal minutes.
Fat loss tracks total energy use, so running creates a larger deficit faster. Walking still burns calories and supports steady loss. Your best pick depends on time, fitness, joints, and how often you will keep going.

How much more does running burn?
For a 155-pound person, 30 minutes of running burns about 280-320 calories, while brisk walking burns about 110-150, Daily Burn reports in its walking-versus-running comparison. That gap equals roughly double the energy in the same time.
The gap matters when time is short. A 30-minute run can match the burn of a much longer brisk walk. Walkers can narrow the gap by going longer or adding hills.
What works best over months?
In a 6.2-year follow-up of 32,216 runners and 15,237 walkers, running produced 90 percent greater weight loss than walking for equal energy use in adults with BMI over 28, researchers in the Williams study report in the long-term weight-loss study. BMI means body mass index, a weight-for-height measure.
Both groups lost weight, McGill University reviewers note. Runners lost significantly more and better maintained loss by continuing to run.
Does walking burn a higher share of fat?
When total calories were matched, incline 12-3-30 walking drew about 41 percent of energy from fat versus about 33 percent for self-paced running, Daily Burn summarizes from a 2025 exercise study in its review of the 12-3-30 workout. Fat oxidation means the body using stored fat for energy.
Running still reached the same burn faster, at about 13.1 versus 10.2 calories per minute. Walking uses a higher share from fat, but running burns more fat per minute. Time decides which effect matters more.
Do you keep burning fat after you stop?
Higher-intensity running creates larger post-exercise oxygen use and fat oxidation. That afterburn means extra energy your body uses to recover.
In men with obesity, interval running showed 66.2 kcal of afterburn versus 53.9 kcal for continuous running, Scientific Reports researchers report. The bonus is real but small. It adds to weight loss, it does not drive it alone.
Which should you choose?
Running carries higher injury burden than walking. One prospective cohort found lower-leg injury in 34 percent of runners versus 13 percent of walkers, Journal of Foot and Ankle Research investigators report in the running and walking injury comparison. Adults need at least 150 minutes weekly of moderate activity such as brisk walking or 75 minutes of vigorous activity such as running, CDC guidance summarized by McGill notes.
Exercise alone works less well, so pair it with eating less. Start with three weekly sessions you can repeat. Add 5 to 10 minutes per week before adding speed.
- Pick walking if joints ache, fitness is low, or you prefer longer sessions.
- Pick running if time is short, joints tolerate it, and you can build mileage slowly.
- Mix both if you want fitness with fewer injury days.
