Weight loss expectations for VSG with 50-60 lbs to lose

"One of my concerns is losing weight too quickly, so that my skin does not retract."

It's a myth that losing weight slowly will make your skin contract better than losing it faster. What happens when you lose fast is that your loss gets ahead of your body's ability to contract the skin. But once you stop losing weight, your skin continues to contract. So in the end you end up in the same place you would have been if you lost slowly, at least skin-wise.

Age seems to be a big factor.  30+ seem to have more elasticity in their skin.  50+ not so much.
