Yogurt key to sexier, slimmer mice

Those looking to improve their love life may find an unlikely ally in the dairy aisle — yogurt.

Massachusetts Institute of Technology researchers Eric Alm and Susan Erdman were interested in discovering why yogurt helps fight age-related weight gain. They fed one group of mice a normal mouse diet. They also fed a second group the same diet with mouse-sized servings of vanilla yogurt.

The yogurt-fed mice did lose more weight than their yogurt-deprived friends. However, researchers also noticed other benefits.

“One of the first things we noticed was their fur coat,” Erdman told ABC News. “It was so thick and shiny; shockingly shiny.”

Researchers also noticed that the males developed a “swagger.”

“There were legitimate physiological differences in males fed probiotics (in yogurt), not just the extra sexiness,” Erdman said. The yogurt-eating males mated faster and produced more offspring.
