    actually kensei, it's partially true about the whole fat burning zone aerobic business. research has shown time and time again that it's not what fuel source you burn which contributes to fat loss, but how many calories in total, regardless of what nutrient you are burning. let's say you lose 1000 calories through glycolysis, that would be carbohydrates, yes, but what happens is, because you have a deficit of 1000 kcal of carbohydrate, your body will degrade fat in order to make up for that deficit. of course that fat cannot be converted into carbohydrate, but the body has a way of playing around with its own fuel supply, and in the end, fat is lost.

    there have been studies that put a weight training group against a cardio group, with both groups consuming and burning the same amount of calories, but with their respective exercises, and in the end, both groups lost the same amount of fat. however, the group that did weights alone also preserved lean tissue, so in the end, they were the more successful group. of course the best would be a combination of cardio and weights, but the bottom line is, just do whatever you can to burn more calories. as long as you burn more calories than what you consume, you'll lose weight.

    Only partially true that the body will degrade fat to make up for that deficit. Your body does not look for JUST fat when it has depleted it's stores of glycogen, it looks for protein as well. Which is why I said, it is a multidisciplinary approach.

    I've seen a study that remotely resumes what you described, but while the calories were the same, but the macronutrient contents were not. Sorry, bad study, everything must be the same to avoid bad extrapolations. What you eat and how much you eat both play a part, and there are no absolutes in this game.

    if the macronutrient contents were not the same, then yes, the study you viewed is a bad one.

    Bryner et al. J Am Coll Nutr. 18(1): 115-121, 1999.
    both groups had the same diet.

    the added loss in body weight by the cardio group was due to loss of lean tissue. the resistance training group preserved the lean body mass, hence the difference in weight.
    the abstract in this link didn't state this, but there was no significant difference between the amount of fat lost in both groups, meaning both lost the same amount of fat.

    for sure, your body will look for protein also, which is why people generally lose muscle when going on a weight loss program. weights will decrease this loss, however.
