Apple or banana scent won't slim you down

A popular claim says that apple or banana aroma helps people lose weight. But there is no evidence that smelling these fruits causes sustained weight loss. In a controlled crossover study, 61 women smelled natural or artificial banana odor or water; banana odor did not significantly change general appetite or the amount of milkshake consumed. Odors can influence food-specific desire depending on context, but that does not demonstrate weight loss.
