I lost over 200 lbs and had a ton of it. It was very easy to hide in clothes, so no one knew it was there except of me (well, other than my husband and doctor). I eventually had it removed, but even if I hadn't, I would have taken thet saggy skin any day of the week over weighing almost 400 lbs again. ANY DAY!
Here's a picture of me BEFORE I had my skin removed. See all that saggy skin? I didn't think so. Honestly, being severely obese vs having some saggy skin that no one can see? It was a no brainer for me.
