Accumulating evidence indicates that pregnancy transiently accelerates biological age and that the postpartum period represents a recovery window during which this acceleration partially reverses. When a subsequent pregnancy begins before recovery is complete, this normalization is truncated and the aging burden may compound across successive pregnancies. We propose that the interpregnancy interval, as the determinant of how much recovery occurs between pregnancies, is the missing variable linking reproductive history to the long-term maternal aging trajectory. We develop falsifiable predictions, identify the study designs needed to test them, and argue that reproductive spacing may be a modifiable determinant of the lifelong aging trajectory.","PeriodicalId":23301,"journal":{"name":"Trends in Endocrinology & Metabolism","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149230038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we frame ATRMR conceptually as the result of shifts in energy budgets within the body. Given the brain’s central role as both a key regulator of energy intake and a major energy consumer within the body, we hypothesize that ATRMR represents one component of the weight-loss-associated reduction in energy expenditure and may reflect a redistribution of energy from the body to the brain, consistent with the hypothesis that adequate cerebral energy supply is preferentially maintained.","PeriodicalId":23301,"journal":{"name":"Trends in Endocrinology & Metabolism","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149152654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
