Interesting idea... being a frequent Photoshopper myself, though, they do look doctored (although for the most part, they don't look *too* unrealistic, so kudos to their pic editors). There's one "before" photo of a woman wearing a patterned shirt over a large tummy, and in the "after" photo they just smudged away some of the bulge in front but didn't bother editing the pattern on the shirt! :P
They also like blurring all the "after" photos a little.
Uh oh... this woman's hand didn't catch up with her hip!
