Cardio is first and foremost heart/lung conditioning. If your working within your Targeted heart rate, then up to 85% of the energy required to sustain it is coming from adipose tissue since glycogen stores have all but been exhausted. Also, the number of total calories would be radically different from one person to the next. For example, someone that is light weight and 'aerobically fit' would consume less calories then someone who isn't. Since there is no metric or baseline for either - how would you know your getting enough calories, or too much? But again... The difference is in ounces. Eating them before or pulling from body fat is the same net result.
Personally I don't believe micro-managing calories is even possible. But i could be wrong.
part is done empirically by tracking the calories and my weight. But as far the eating/cardio goes, it starts out with an estimate of how much cardio for X calories. The idea is that I add X calories and do approximately X calories of cardio WHILE LEAVING EVERYTHING ELSE THE SAME (calorie intake, meal frequency, calorie balance) whether bulking or cutting.
I actually do think there is an advantage - heart conditioning as well as more calories of micronutrition opportunity. The question is whether or not the additional cardio will demand additional micronutrition equal to the X extra calories consumed. I do know people with higher metabolism are at an advantage, whether cutting or bulking. Part of the reason is the additional micronutrition opportunity (i.e. someone who burns 3000 calories a day and is running a 500 calorie deficit gets 500 more calories of intake micronutrtion opportunity compared to someone who bursn 2500 calories a day and is running a 500 calorie deficit). I'm thinking "calorie covered cardio" may actually end up simulating a faster metabolism ... plus the heart workout benefit.
