Blood Vessels

Forgive me for bringing this up at this time of year, but I found it interesting. Every pound of fat gained causes your body to make 7 new miles of blood vessels. Knowing this, it’s easy to see why obesity and heart disease often go together. Most of the new blood vessels are tiny capillaries, but also include small veins and arteries. This means if you are “only” 10 pounds overweight your heart has to pump blood through an extra 70 miles of blood vessels.

The good news is that this also works in reverse. If you lose a pound of fat, your body will break down and reabsorb the no longer needed blood vessels. This is encouraging to dieters, as one pound does not seem like a lot to lose, but even that little bit of difference will result in a large benefit for your heart.
