A new study in mice suggests that it's not just how much you eat, but when you eat it, that influences weight gain.
Researchers at Northwestern University wanted to test whether the timing of meals could influence body weight. Many diet books advise would-be weight losers to stop eating after 6 or 7 p.m. However, it's never been clear if the strategy works as a behavioral change -- we tend to overeat in the evenings in front of the television and the computer. Or is there some physiological reason late-night eating adds extra pounds?
