Maternal exposure to high-fat diets during pregnancy programs fetal hypothalamic development to predispose offspring to obesity and metabolic complications, independent of maternal obesity.

A mother's diet during pregnancy, specifically high-fat intake, can program her child's brain to crave more food and store fat more easily. This happens even if the mother doesn't become obese. Pregnant women should prioritize balanced, low-fat diets to protect their child's long-term metabolic health.

foetuses of the high-fat diet-fed mothers exhibited increased liver fat and markers of oxidative stress... Offspring of female monkeys exposed to a high-fat diet in pregnancy also show changes in neurons in the arcuate nucleus that synthesize POMC and AgRP, suggesting that dietary composition may programme the fetal brain to develop an obese state

Why this rating

Strong evidence from non-human primate models, though direct human application is noted as plausible but not definitively proven.
