Walking and running consume the same distance. Walking for 5 kilometers consumes about 450 calories per hour, and running for 12 kilometers consumes about 1 100 per hour, so walking for two hours 10 kilometers consumes 900 calories and running for 50 minutes consumes 900 calories. Running burns as many calories as walking. The difference between running and walking is that they consume energy at different rates. Running consumes energy faster than walking.

The calorie content in food is a measure of how much potential energy food produces. 1g carbohydrate contains 4 calories, 1g protein contains 4 calories, and 1g fat contains 9 calories. Food is generally composed of these three substances. Therefore, as long as we know the contents of these three substances in food, we can know how much heat or energy food contains. From the perspective of losing weight, running is better than walking. The same time or distance consumes the same amount of calories, but running burns calories more efficiently.
