I was going to post this - I found the article via a fitness blog I love (The Great Fitness Experiment).
The part that stuck with me was this:
“This study shows that conventional wisdom — to eat everything in moderation, eat fewer calories and avoid fatty foods — isn’t the best approach,” Dr. Dariush Mozaffarian, a cardiologist and epidemiologist at the Harvard School of Public Health and lead author of the study, said in an interview. “What you eat makes quite a difference. Just counting calories won’t matter much unless you look at the kinds of calories you’re eating.”
Hmm, so now Harvard researchers are saying a calorie ISN'T just a calorie? not just calories in and calories out, you say?
I really, REALLY wish the researcher hadn't used the terminology of "good/bad calories" though. I know some people think it's just shorthand and semantics, but I think there's a moral judgment there that's just wrong and causes a lot of people to have trouble with food. Even "more/less nutritious" would be better!
