Sleep may aid post-pregnancy weight loss

There could be a reason why some women lose weight faster than others after having a baby. The key could be sleep, or lack of it. A new study done by Kaiser Permanente in California finds sleep may be just as important as diet and exercise for shedding baby weight. One study has found that new moms who slept five or fewer hours a day, six months after giving birth, were three times as likely to hold onto those extra pounds as were women who got seven or more hours of sleep.

Researchers say how long a woman breast fed was not a significant factor in weight loss.
