Losing Body Fat Before Pregnancy Can Be Beneficial for Your Baby

If obese mothers lose body fat before pregnancy, does it improve the lifelong health of their children? A recent research study showed that this may indeed be the case.

Researchers induced maternal obesity in female rats prior to pregnancy. One group continued on an obesity-inducing diet from weaning throughout pregnancy and lactation. A second group was switched to normal food one month before mating.

Eurekalert reports:

"At weaning, triglycerides, leptin, insulin and insulin resistance were elevated in offspring of obese mothers and all returned to normal if their mothers had received prepregnancy dietary intervention. Fat mass and fat cell size were increased in offspring of fat mothers and these changes were significantly reversed, though not completely abolished, by the dietary intervention."
