Although you can find estimates for calories burned during various activities, it's almost an exercise in futility to try and calculate how many calories you are actually burning per day, because there is so much difference between each person's metabolism that it is impossible to say something like "running burns X calories per hour" and have it be true for everyone.
On the other hand, you can calculate exactly how many calories you consume each day. You can also weigh yourself first thing each morning. By using calories consumed as the input, and your weight (and the mirror) as the output, you have more control over the situation. I'm not saying cardio is bad, but it is not necessary to lose fat, and it is easier to track and manipulate your diet than sit down and try to guesstimate how many calories are actually being burned during exercise.
