Women’s bodies tend to break down fats more actively just under the skin than men’s do, which might help them store more fat there—this could be one reason why women often carry more fat in areas like hips and thighs.

Scientists found that women’s fat cells under the skin have about twice as much of an enzyme that helps store fat as men’s do, which means women’s bodies may be naturally set up to store more fat in this area — just like the claim says.
