Below are before and after pictures of Katharine McPhee. As you can see, she has lost a LOT of weight since the beginning of the last "American Idol".

Here's Lindsay. She has a lot of photos in many stages of weight loss and gain:

Here are not two, but three pictures documenting her stunning weight loss over the period of two years. Actually, she gained weight between 2002 and 2003, but she looks great now:

The man she's with is Joel Madden.

We all noticed that Britney Spears has lost just about all of her baby weight.Remember that she had two kids, one after the other, so she really had a lot to lose. Here's her "before and after" photos:

It's quite impressive, isn't it?

In more American Idol contestants, here are two pictures of Carrie Underwood. As you can see, she's getting smaller too:

Here's Jennifer Aniston and as you can clearly see, she's whittled herself down quite dramatically over the years:

I realize that Jo Jo is still a child and therefore, not fully grown as yet, but you can see by these two photos of her, taken just a few short years apart, indicate that this talented girl has lost some serious weight since the beginning of her professional career. I am doing a separate article on her later on and it will be posted on the site. I hope Jo Jo, who was quite chubby on "America's Most Talented Kid" won't succumb to the skeleton brigade:

Probably the celebrity who has transformed herself the most dramatically would have to be Kate Bosworth. We aren't sure whether it's drugs or anorexia--most likely a little of both---but as you can see in this large photo, Kate was a normal weight. However, in the second, she's rail-thin and getting smaller by the hour. Am I bad for wishing I looked like that? I'm sure many of you are nodding your heads:

As you can see, the healthy picture is HUGE. I deliberately posted it just to show the drastic change in Kate over the past year or so.
