Anna Nicole Smith is selling a lie by attributing her "new look" to Trim Spa (a diet suppliment, kind of like Metabolife). Here is Anna Nicole, before and after her rapid weight loss:

In the "before" picture Anne Nicole Smith is pushing 230lbs (remember she is almost 6ft tall) and I'm going to guess that her weight in the "after" picture is 120lb. So, she has defiantely lost over 100lbs, which, hey, that's great! BUT, there is NO way that she did not undergo plastic surgery to help and tune up her body. Here are some before & after pictures of a tummy tuck done on a women that lost 140lbs:

Now, unless Anna Nicole Smith has magic skin, she looked very similar to this after losing so much weight. Once you stretch your skin past a certain point, it's not going to snap back. Plus, she is almost 40 years old and has a kid, so she has already lost elasticity in her skin. I'm going to say that after Anna Nicole Smith lost all that weight she had a breast lift, liposuction, tummy tuck and a leg lift. Which would be fine by me if she wasn't claiming that some bunk weight loss suppliment is her "secret". A good plastic surgeon is her secret. I find it so annoying when celebrities lie to the public to try and sell shit...
Edit: After doing some more research it looks like Anna Nicole received a plastic surgery "package" called
body contouring and a
lower body lift. Doesn't that sound a lot nicer then breast lift, tummy tuck, liposuctions, etc? Haha...
