It’s time for another one of DietNation’s top 10 lists. Today I’ve decided to do the top 10 worst celebrity bodies. I’ve chosen the 10 bodies that I feel are unhealthy for a couple of reasons. Some have had far too much plastic surgery done, some have issues with fluctuating weight and some are just too skinny.

Anna Nicole Smith - Anna Nicole Smith made Trimspa famous and went through an incredible weight loss transformation. This blonde bombshell may have been a playmate in the ‘90’s but her figure now is definitely not playmate-worthy.

Janet Jackson - Janet may be known for having the nicest abs in the industry, but has she really achieved them on her own? Knowing her family’s track record for spending time with a plastic surgeon, it’s been speculated that she may have had some ribs removed to get her chiseled flat stomach. Another reason Ms. Jackson made the list is for her unhealthy fluctuating weight. Her small frame should not put on as much weight as she did earlier this year.

Kirstie Alley - it’s no secret that Kirstie Alley’s weight was out of control before she signed on with Jenny Craig. At 203 pounds she was an unhealthy weight for her size. She’s now lost about 75 pounds and even flaunted her slimmed down body on Oprah’s show in a bikini, but will she be able to keep the weight off for good? Kirstie made this list for letting herself get that out of control in the first place.

Tori Spelling - the positive outcome of Tori’s inheritance settlement is she won’t have a lot of extra money left over to get any more plastic surgery done. Although Tori is presently pregnant, she’s had so much work done on her body that it’s difficult to determine what’s real and what’s fake.

Victoria Beckham - Earth to Posh - you look like an alien! Seriously, have you seen pics of the former Spice Girl lately? She kind of resembles an alien. Victoria Beckham was definitely the hottest Spice Girl but lately she has been losing weight like crazy and could stand to pack on a few pounds to fill out her gaunt figure.

Star Jones - Star Jones seemed to slim down to a svelte size 8 overnight. She magically lost 150 pounds in no time and vehemently denied that she had gastric bypass surgery to melt off all those pounds. She confessed to having her breasts augmented and a tummy tuck, but continues to deny the bypass surgery.

Tara Reid - when Tara Reid was in American Pie she was a pretty blonde with a great body but now she’s spent a bit too much time with her plastic surgeon. Lately it seems Tara is making headlines for her unattractive surgeries and not her acting ability. She recently went public about her botched *** augmentation and it’s evident that she had some liposuction. Note to Tara: if you got yourself to the gym and cut down on the boozing you could get your body back naturally.

Keira Knightley - Keira has always been on the thin side but lately she has been taking things a little bit too far. She has absolutely no curves on her frame and I’m surprised she can still find clothes that fit.

Nicole Richie - last month Nicole admitted that she was going to a clinic to help her put on some weight. Nicole ranks on this list for having an unhealthy body B.W.L (before weight loss). Nicole was pudgy and downright unattractive when she appeared on the first season of the Simple Life. She also ranks on this list A.W.L. (after weight loss). We’ve all seen the skeletal images of Nicole - enough said.

Mariah Carey - I saw Mariah Carey in concert this summer and was shocked at how big she is up close. I had read all the stories about her losing a ton of weight this summer by following her own ‘morsel diet’ plan but was stunned at how big she really was. Mariah needs to get it into perspective and realize tube dresses and booty shorts aren’t flattering for every figure.
