Depressing study showing that exercise does not prevent weight gain for middle-aged women...unless they're already at a healthy weight. Le sigh.
Of course as with any study, it raises as many questions as it answers. And since only the abstract is available at no cost on the JAMA site, I'm not sure if the answers are available or not.
Like: Isn't weight loss still (mostly) a mathematical equation? Is the fact that exercise did not prevent weight gain indicative that women who exercised were eating more to fuel their energy to exercise? Or is it disproving the whole generally accepted notion that weight loss is all about calories in vs. calories out.
Inquiring minds want to know, but might be too lazy to find out. Since, you know, there's now no motivation not to be lazy, right?
What? Is that not how I'm supposed to interpret this study? :)
