Historically, pregnant women were advised to refrain from exercise because of concerns about fetal risk. Simultaneously, they were advised to increase their caloric intake during pregnancy. However (in part because of these misguided recommendations), some of the weight gained during pregnancy was usually retained. Elevated maternal weight is associated with a higher birth weight of offspring and contributes to the intergenerational transmission of obesity.1 Consequently, pregnancy has evolved as a major contributor to the worldwide obesity epidemic and multiple related maternal and fetal comorbidities, some of which have potential lifelong consequences.
