Hey T, I have been searching online about loose skin after weight loss and came across something I think you might like to read. It doesn't explain why but here is what I found....
When to Consider Surgery for Loose Skin
Skin can only be stretched so far before it looses some of its ability to snap back. If you’ve had a 9-month pregnancy, then you’ll be able to tighten your loose skin. But if you’ve carried a hundred or more extra pounds for many years, you may be a candidate for plastic surgery to tighten and lift loose skin. This fix should only be used in extreme cases, and I should warn you: my clients who have undergone this operation have actually gained more fat afterwards while they were rehabilitating from surgery!
That last sentence is what I was thinking about, as I said it doesn't say why, but it looks like its a common problem, maybe its to do with mindset or food or something. So don't lose your way hunni, it looks as though you are going throu what is normal!!
