I based that on this quote: >These changes in how they spent their time neatly managed to almost counteract the extra calorie costs from running, says Daniel Lark, a research fellow in molecular physiology at the Vanderbilt University School of Medicine, who led the new study. And as this is a mouse study I make no comments on how to extrapolate that to humans. If this is behavioral and not biological then it might not translate at all.
