This might sound really stupid but maybe someone can expain it to me...using the exercise tracker why do you not burn more calories if you can walk/run the same mileage in a shorter amount of time than before losing weight.....i thought since you are walking at a faster pace you would ....just wondering...thanks

Previously you were carrying more weight which meant that you worked harder carrying that extra weight and burnt more calories. If you carried extra weight and did the same walk / run, you would burn more calories.

As you exercise your body becomes more efficient and it takes less energy to accomplish the same amount of work and as you lose weight it takes less energy to move you (there's less mass fighting gravity).

I think you are asking why you get the same number of calories if you walk a mile in 15 minutes (4 miles per hour) or the same mile in 30 minutes (2 miles per hour). If you walk twice as fast, yes, you are burning calories at a faster rate . . . but for a shorter length of time. There have been studies of calories burned and for walking it really is generally a function of distance, not distance and speed. There will be a difference once you start to run instead of walk since you move your body differently so the number of calories per mile changes. But even with running, to the first order, it's a function of distance, not distance and speed.

Or maybe you were asking something else entirely . . .

Calories per Mile
Between the speeds of 5 and 9 miles per hour, runners expend almost the same calories per mile. . . .

Walkers also see very little difference in calories per mile at walking speeds between 2.5 and 4 miles per hour. While they burn the same calories per mile as runners if they can go 5 mph, they burn fewer calories per mile at slower speeds. They can easily make up that difference in a workout by going further in distance.

thanks....i guess i will have start walking for a longer distance....I am not a runner...LOL

Me neither! The advantage of walking faster is you can go that longer distance in a shorter time.

or you can just start adding in walking intervals. walk at your regular speed for like 90 seconds then for the next 30 seconds speed walk.
i personally prefer making my workout harder than making it longer

it all goes by heartrate and age.. use the formula and calculate the right calories

so according to the calc
if i wasnt fit and did the mile in 20 min and my heart rate was 110bpm i would burn 193 calories
i get fit and i walk fast my heart rate is 130bpm it takes me 15 min to complete the mile my calories burned are 190.. and i shaved off 5 min
