Sexual behavior: dietary food switch induced by sex.
Pregnancy in humans induces cravings for special food: the same occurs in Drosophila females. New work now shows that mating throws a nutritional switch in favor of a high-protein diet and that modulation of nutritional balance depends on the sex peptide receptor and involves neuronal TOR-S6 kinase signaling.
