ELI5: What happens to the extra veins and other blood vessels when you lose fat?

I heard for every pound of fat you have, your body makes 7 miles of veins and blood vessels. Where do they go when you lose weight?

Your body can program cells to essentially "self-destruct" (this is called apoptosis). Since blood vessels are made of cells, your body will divert blood away from these blood vessels and essentially destroy them through apoptosis (although, in this case, it's more like recycling, because all of the stuff released from these cells can be reused). It takes time (just like losing weight), so it occurs at the same time.
