Obese mothers ‘can leave babies prone to diabetes and weight-gain’
Scientists made the discovery after investigating why children whose mothers are obese are at greater risk of metabolic problems as they age.

Taking species differences into account, the findings imply that a human mother’s nutrition in the last three months of pregnancy is critical to her child’s future health.
“Our study suggests that expecting mothers can have major impact on the long-term metabolic health of their children by properly controlling nutrition during this critical developmental period of the offspring,” US researcher Professor Tamas Horvath, from Yale School of Medicine, said.
“Mothers can control or even reverse their offspring’s predisposition to obesity and resulting diseases by altering their food intake.”

Previous research has also failed to pinpoint the most critical stage before or after birth when maternal nutrition has the greatest impact on a child’s metabolic health.
To address these questions Prof Horvath’s team and colleagues in Germany used a laboratory mouse to probe metabolic programming.
