Our body is many things: a mechanical device, a walking chemistry set, a sustainable life form, and an ever-changing biological phenomenon. There’s a lot to know about the body. Were you aware of these ten amazing facts?
For every pound of fat gained, we add seven miles of new blood vessels.
New tissue needs blood supply, so our vascular system expands to accommodate it. This also means our heart must work harder to pump blood through the new network, which may reduce oxygenation and nutrient replenishment in other tissues. Lose a pound? Our body will break down and reabsorb the unneeded blood vessels from the previous tissue.
Muscle tissue is three times more efficient at burning calories than fat.
This is why possessing more muscle should be a training goal for most people. More muscle = more calories burned = less fat = being more fit looking. Simple goals and simple math.
