about skin fat

Ok...im watching Ophrah right now and they are featuring weight-loss records.. Men and women losing 200-500 lbs. of fat from 1-3 years...Question...What happens to the excess skin?...Do you have it removed surgically or is there a way to tighten it through excersie?

if there's a lot of it, it gets surgically removed

Both.Depends on the person, and how fast they lose the weight, and how long they want to wait for it to happen. A woman I work with got gastric bypass surgery, and for about half a year her skin was a bit saggy, but now it's tightened back up without surgery.

so....Slow weight lost equals tight or less excess skin?
Fast weight lost equals lots of excess skin?

Replying to #4

more or less.

does the "roughness" of excercise count as a variable?

I presume the "roughness" of exercise doesn't count as a variable

So assuming that you do jogging, martial arts, swimming, or running,..it makes no difference to just plain walking?

Cardio is for fat, not necessarily skin. A lot of excess skin would have to be surgically removed yeah.
