Pre-pregnancy lifestyle interventions (dietary restriction or exercise) initiated at least 9 weeks prior to conception reduce the risk of metabolic-associated fatty liver disease (MAFLD) in offspring of obese mothers, whereas interventions initiated only 1 week prior do not.

If you have obesity and plan to conceive, starting weight management 9+ weeks before trying to get pregnant is critical for your future child's liver health. Standard lifestyle changes may take too long, so discuss pre-pregnancy pharmacotherapy (like GLP-1 agonists) with your doctor to ensure you reach a healthy weight before conception.

ModerateSupportsMEDIUM confidence
dietary intervention only 1 week prior to conception did not alleviate the risks associated with maternal obesity for the offspring... However, similar to the study in Japanese macaques, this was avoided in the offspring of mothers with dietary intervention 9 weeks prior to conception, suggesting that early maternal dietary intervention is effective in reducing the risk of MAFLD in the offspring of mothers with obesity [52].

Why this rating

Based on preclinical animal models (mice, macaques, baboons) and human cohort associations, but lacks direct human interventional trials for offspring liver outcomes.
