Someone I know has recently lost 150 lbs (about 11 stone) in the space of a year.
He / she has done it sensibly through exercise and diet, but the weight has dropped off v. quickly.
He / she now has a load of loose skin, particularly under the arms and around the tummy.
Does the skin shrink to fit the new body shape, or does once stretched does it remain that size?
How long would it take to get back to “normal” (ie. in proportion to the new, lower weight)?
