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.

- Estrogen directs fat distribution to subcutaneous gluteo-femoral depots in premenopausal women, which is protective against cardiometabolic risk, whereas estrogen deficiency (menopause) shifts distribution to visceral fat, increasing risk.Strong
- Women exhibit lower total daily energy expenditure than men independent of fat-free mass, and physical activity interventions result in smaller fat loss in women compared to men due to metabolic and compensatory dietary responses.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
