Question: how long does it take to lose weight just by walking?
Answer: In order to burn calories from fat, you need to keep up that speed for a minimum of 30 to 50 minutes, after having warmed up with a 10-minute walk at your natural pace. It is generally accepted that a person weighing around 70kg will burn an average of 300 calories after 1 hour of fitness walking at 6 km/h.
