When people alot of weight , why is there excess skin left when they are thin?

When the body reaches a certain point in weight gain (i.e. morbidly obese not just a little fat) then the skin stretches beyond the point of no return. The skin stretches sooo much that it loses the ability to come back to where it was (over-stretched) originally and they now have to do surgery to remove it.





Keep in mind that this only happens at a certain point in weight gain which means HUGE! I think it's at 300 pounds or more for some people.

skin stretches out to accommodate the fat, but it doesn't automatically stretch back if it's been big for a long time.. kind of like elastic in underwear!!
Reply:because they only loose the fat/cellulite and the skin around it has already been stretched from being fat for a long period of time.
Reply:The skin has been stretched out so long by the excess bulk that it does not return to its original shape.
Reply:The skin has taken longer to return to it's normal size then it did to burn the cellulite. This normally only happens when one is very ill and loses a lot of weight very rapidly, loses the weight via an un-healthy method (ie: fasting) or you get liposuction.
Reply:The answers above are generally correct. I would only like to note that skin does not stretch. It actually grows by adding more cells. These cells will have to die off of be destroyed before skin can become smaller.
