It has been proven that overweight mothers are more likely to have overweight babies, and the gut bacteria the babies inherit may in part be to blame according to some researchers. According to a recent study that included 935 mother-infant pairs, overweight mothers are more likely to have a cesarean section, and that babies born by cesarean to those mothers have species of gut bacteria different from those in babies born to normal weight women. They specifically found an abundance of bacteria of the family Lachnospiraceae in infants of overweight mothers which may contribute to an increased risk for obesity.
These pairs were compared to children born to normal weight mothers, those born vaginally to overweight women were more than three times as likely to be overweight by age 3. But C-section babies born to overweight mothers were more than five times as likely to be overweight. However, for normal weight mothers, vaginal or C-section delivery made no difference in the risk for overweight babies. Unfortunately, there is no probiotic that would lead to a positive change in gut bacteria but breastfeeding is effective in helping to prevent infants from becoming overweight and even helps mothers lose that extra baby weight.
