Epigenetic germline inheritance of diet-induced obesity and insulin resistance : Nature Genetics : Nature Publishing Group

"There is considerable controversy regarding epigenetic inheritance in mammalian gametes. Using in vitro fertilization to ensure exclusive inheritance via the gametes, we show that a parental high-fat diet renders offspring more susceptible to developing obesity and diabetes in a sex- and parent of origin–specific mode. The epigenetic inheritance of acquired metabolic disorders may contribute to the current obesity and diabetes pandemic."
