The Celebrity Weight Loss Hall of Fame... and Shame

We've brought you our Plastic Surgery Hall of Fame. Now we present to you our Celebrity Weight Loss Hall of Fame ... or Shame, as it is in many cases.

For every celebrity weight loss success, there is an equal and opposite celebrity weight gain... or celebrity weight loss gone horribly, horribly overboard.

Sometimes stars mean well, but fall off the boat and pack the pounds back on. Other times, they end up trying TOO hard and skipping a meal or 30.

The technical term for the latter is Mischa Barton Syndrome (MBS). Here's a look at the former OC star looking healthy last year and emaciated now ...

Wow. Looking good, Mischa. When was your last meal, Thanksgiving?

Follow the jump for many more examples of celebrity weight loss winners and losers - those who have either tried way too hard or not hard enough.

NOTE: In the interest of mixing it up a bit, we didn't even include Jessica Simpson - though you can find many, many photos of her on our site!

Now, on to the Hall of Fame and Shamers ...

We love Jennifer Love. But Hewitt's critics had a field day with this.

Britney Spears in her prime and during her '07 VMA meltdown. Wow.

Tyra Banks is much heavier - and more annoying - than in the old days.

Lindsay Lohan used to have adorable girl-next-door qualities. Now she just has anorexic-waif-you-hooked-up-with-and-threw-out-the-door qualities.

Kate Bosworth also suffers from Mischa Barton Syndrome.

Sorry, we lied. We couldn't resist. Just look at that outfit!!

YOWZA! Finally, we have a winner. Carrie Underwood wasn't overweight to begin with, but slimmed down and toned up while still looking positively stunning.
