Muscle does not weigh more than fat, any more than lead weighs more than feathers. A pound is a pound is a pound. Where the misunderstanding often comes in is that muscle is much more dense than fat, so that, by volume, it seems to weigh more. That is, a pound of muscle occupies less space than a pound of fat.

This causes the arteries to become narrower. The walls of the arteries also become stiffer and cannot widen (dilate) to allow greater blood flow when needed. As a result, when the muscles of your legs are working harder (such as during exercise or walking) they cannot get enough blood and oxygen. Eventually, there may not be enough blood and oxygen, even when the muscles are resting. Peripheral artery disease is a common disorder that usually affects men over age 50.
