I was told they Do Multiply. Apparently, they grow to a certain size, and they Mutate and split off, forming another FAT CELL! (mUTha F##k).
I have a few friends who NEVER GET FAT. They drink cases of beer, booze, ton's of Carbs and they just don't have any fat cells on their Bodies (Mo-F##kers!). Then i know some ppl who Just look at a plate of spaghetti and gain 10 lbs overnight....
Nature has played a Cruel Hoax on Man...
..."Even extreme events—for example, dramatic weight loss through surgery or super-sized weight gain—change the size of fat cells in the body, but don’t nudge the number. (That said, many experts believe years of excessive weight gain that lead to hundreds of extra pounds will eventually cause fat cells to multiply.)"
