Question: how much weight will you lose if you walk 30 minutes a day?
Answer: The thumb rule is for every 1 minute you walk you burn approx 6-7 calories. So if you just walk for 30 mins you will be burning close to 200 calories per day. For 28 days, you would be burning 5600 calories. Now for every 7000 extra calories you burn you lose 1kg.
