There is good evidence that you cannot simply burn off calories this way. That the body will reduce energy consumption at other times to compensate. The overall effect of exercise on energy consumed by the body is minimal. That is, exercise does not build metabolism and in the absence of increased food intake exercise will result in lower metabolism. Try reading Good Calories, Bad Calories. I've been surprised by the number of things I have thought or been taught that are directly contradicted by the experiments reported in this book.

(1985) in a twelve-week study, with obese men, reported that when the negative energy balance created by diet only and exercise only are equal, the two treatments produce similar results. The participants in the diet only group (n=10) experienced a weight loss of 6.1kg by restricting their caloric intake 500 kcal/day. The exercise only group (n=6) lost 6.2 kg by performing a treadmill walking program in which they expended 500 kcal/day. The men in the diet only group went from a body fat of 31.4% to 25%, where as the exercise only group went from 26.7% to 19%" From reading this, it seem like many studies didn't attempt to make calorie deficit equal.

It seems here there is also a subject selection problem. A 5% body fat difference for starting out is pretty significant. This is the trouble with the vast majority of this research. It's done in such a way that it's hard to learn much from it.
