I'm trying to work out my bmr and so the amount of calories i burn a day. Based on the online calculator for my height and weight, 14 stone and 5"11, my bmr is 1800, which is a fairly average value I'd guess. Given that the the recommendation for men is to consume up to 2500 calories per day, this would leave 700 calories a day to be burned off by exercise.
Using my fitness tracker app 700 would require roughly 12 miles brisk walk ever day. This sounds like a lot to me, and I find it very difficult to believe that the average person walks 12 miles a day.
Can someone explain to me how this 2500 calories value can be correct for the average man?
