The one thing that might be said about exercise with certainty is that it tends to makes us hungry. Maybe not immediately, but eventually. Burn more calories and the odds are very good that we’ll consume more as well. And this simple fact alone might explain both the scientific evidence and a nation’s worth of sorely disappointing anecdotal experience.
It’s difficult to get health authorities to talk about the disconnect between their official recommendations and the scientific evidence that underlies it because they want to encourage us to exercise, even if their primary reason for doing so is highly debatable. Steve Blair, for instance, a University of South Carolina exercise scientist and a co-author of the AHA-ACSM guidelines, says he was “short, fat, and bald” when he started running in his thirties and he is short, fatter, and balder now, at age 68. In the intervening years, he estimates, he has run close to 80,000 miles and gained about 30 pounds.
