Thanks to a diabetes drug, obese mothers-to-be will be able to prevent their babies from inheriting the fat factor. According to a new clinical trial, obesity of a child can be controlled in the mother's womb through a metformin if taken up to three times a day during pregnancy, reports the Daily Mail.

With studies suggesting that the seeds of obesity are sown in the womb, early intervention could save youngsters from a lifetime of weight problems and ill-health. The treatment is designed to reduce the food supply to the baby, rather than make the expectant mother lose weight herself. Metformin, which costs pennies per tablet, has been safely used by diabetics for decades and is cleared for the treatment of diabetes in pregnancy.
