The Wall Street Journal recently had a headline that made lots of people smile, I’m sure: A Chocolate a Day to Get Slimmer?
It discussed a new study that found people who eat chocolate regularly tend to be slimmer. But just saying that points out the problem with many studies on food intake and calories, disease, etc. While statistical relationships may exist between an action and a condition, that doesn’t mean one causes the other.
Indeed, the Journal reported that “But before people hoping to lose weight indulge in an extra scoop of chocolate fudge swirl, the researchers caution that the study doesn’t prove a link between frequent chocolate munching and weight loss.”
