Why did you crop out the girl in that last picture?
Not my place to post another person's picture on the internet. :)
Nice answer, +1 internet coolness gained.
I was wondering, does the loose skin 'tighten up' over time?
And what if a person looses a lot of weight, but over a long time, has he got less problems with loose skin?
Your skin will tighten up - how much is dependent on a few factors from what I understand:
How long you were over weight.
How fast you gained the weight.
How much you lost.
