This article, including the title, is a bit of a mess. Nothing in it refutes the commonly accepted principle that if you burn as many daily calories in exercise as you consume in food, you will not get fatter. The point of the article seems to be simply that the modern Western diet is so high in calories that it&#x27;s difficult to do enough exercise to make up the difference. The survey study they cite talks about exercise in the range of only a couple of hundred calories a day, and even then, contrary to what the article implies, the study&#x27;s conclusion clearly states that weight loss was proportional to the amount of exercise. So, sure, if you&#x27;re eating 1000 calories&#x2F;day more than you&#x27;re burning, throwing in an extra 30-minute walk on the treadmill isn&#x27;t going to do much. But try a real exercise regimen like P90X where you <i>are</i> burning an extra 800 calories or so a day, and you absolutely will see results even if your diet remains unchanged.
