Another really interesting article by Gina Kolata. This one is about misconceptions about caloric intake and caloric burn--it is constantly surprising to me how little people know about health issues like this one. For instance, I am really shocked to hear that a spinning instructor would tell their class that they just burned 900 calories in 45 minutes.
I guess people will believe what they want to believe about health-related things. And I will probably continue to be surprised by it. In the end, it all makes sense, I guess. Our country didn't get its high obesity rate by having a thorough comprehension of diet and exercise.
