I have been very interested in watts and body weight for an individual. The specific interest I have been searching for is the relationship of weight loss or gain has on watts. For instance in a controlled test for the individual that weighs X amount of kg then losses X amount of body fat and the individual applies the same watts in a controlled experiment how does the change in weight affect wattage? For instance if I picture a cyclist going up a 6% hill with repeatable environmental conditons, bike etc and he goes up the hill at 6 mph at 200 watts then the same person does the same experiment after loosing 10lbs of fat what will the watts be to do the same xperiment? The specific watts is not necessarily the answer I am looking for but a ratio of weight lose to watts/speed perhaps? For instance 10watts per pound in general? I hope I made myself clear. I am starting to confuse myself. Mike
