The impact of exposure to cafeteria diet during pregnancy or lactation on offspring growth and adiposity before weaning
Abstract Exposure to maternal obesity during early-life can have adverse consequences for offspring growth and adiposity. We aimed to assess the relative contributions of exposure to maternal obesity, induced by a highly varied cafeteria diet, during pregnancy and lactation on these measures in rat...
