What happened

A recent study conducted by Yerkes Primate Research Center in Atlanta, which observed dominant and subordinate rhesus monkeys, found that stressed female monkeys ate more fat and sugar than those who weren't under stress.

The "cultural mandates of beauty," the "evolution of self control," and the reinforcing cycle of stress and dopamine all "facilitate the restraint and binge dynamic." Rhesus monkeys don't have the "emotional baggage" that humans do. "We humans can internalize our mix of ideals and status, and that then plays into our overall brain function, behavior, and sense of self."
