Does walking or running burn more fat?

Running oxidises more total fat per session due to higher total energy cost, even though a smaller percentage comes from fat. Running also oxidises more protein than brisk walking. The comparison table on the page carries the current figures for 180 lb over 30 minutes.

Is Walking Better Than Running for Fat Loss?

Q: Is walking better than running for fat loss?

Running oxidises more total fat per session because it costs more total energy, but walking draws a higher percentage of its energy from fat. Walking also oxidises less protein and requires no recovery. Neither figure is fat lost — total intake over the day decides that. Which matters more depends on individual goals.

Two activities, two outcomes. 180-lb person, 30-minute session.

Walking — 3.5 mph, 30 min

Net calories ~135

From fat ~61%

Fat oxidised ~9g

Running — 6.0 mph, 30 min

Net calories ~359

From fat ~36%

Fat oxidised ~14g

The protein cost

Running 6.0 mph, 30 min

~15g

protein burned
about 2.5 eggs (at 6g each)

Walking 3.5 mph, 30 min

~4g

protein burned
less than one egg

Fat-adapted individuals — those following carnivore, ketogenic, or low-carbohydrate diets long-term — may shift these ratios further toward fat oxidation at all intensities. The percentages above reflect general population averages from published exercise physiology research. Individual substrate utilization depends on metabolic state, training history, and glycogen availability.
