Predicted versus Actual loss

BearJuden

Yah, so, I have noticed when inputting how much I've run/biked (on the treadmill/machine): when I run, the amount of calories I actually burn (what the treadmill says) is always lower than what the formula predicts when I input it, and when I bike, the amount I actually burn is almost always higher than the predicted amount.

I understand this isn't a particularly vital issue, but in the interest of curiosity, is there any particular reason for this?

Formulas for calculating calorie burns can be wildly variable.

Your best bet is to see how you do over time. If you know you eat 1500 calories per day and lose two pounds a week, you are probably burning an average 2500 total per day. (7000 calorie deficit per week = 2 pounds.)
