Kim Kardashian Weight Loss

Celebrities can afford personal chefs, personal trainers and lots of plastic surgery.

Still, Life & Style seems to think the reason why various stars look good in a bikini is a big mystery - and the tabloid is excited to reveal it in its latest issue!

A trio of beauties opened up to the magazine about their secrets behind their bangin bodies. Read what they have to say below...

Rihanna: "I like wearing a bikini with a cover-up that's loose, not too long and a little bit sheer... If I know I'm going on vacation, I'll do Pilates for two weeks straight."

Kim Kardashian, who tries to emphasis her iconic backside: "I love to put the treadmill on maximum incline and run backward. It's good to switch it up - run forward for 10 minutes, then backward for 10 minutes. Repeat for 40 minutes total and you'll really see results in your booty."

Kristin Cavallari: "I have very little hips, so a string bikini gives me curves and pushes up my boobs... I drink a ton of water and eat stuff that doesn't make me bloat, like fresh fruits and veggies."

Mischa Barton may be fighting for her life... but certain celebrities look good in bikinis! Which story would you highlight?

Which is it, Kim Kardashian? Are you happy with your curves or aren't you?!?

In March, the reality TV star spoke proudly about her body, railing against critics that mocked her cellulite and setting a good example for women by saying "just because I am on the cover of a magazine doesn't mean I'm perfect."

We applauded her stance at the time.

Now, however, sister Khloe Kardashian graces the cover of Life & Style, on which she brags about the 20 pounds of weight Kim helped her shed. And just how did the siblings team up to trim down?

Through a quick-fix, unhealthy system of "cleansing;" i.e. a politically correct form of bulimia, involving the evacuation of all sustenance out the other end.

Kim Kardashian was proud of her curves... until she discovered a way to pad her bank account by saying otherwise.

In fact, Kim and Khloe are even shilling their very own cleansing product. It's called Quick Trim and it will soon be on sale at GNC.

“It’s a lemonade-based cleanse. It’s ready to go! Khloe has lost 20 pounds off of it,” Kim said this week. “I tried the pepper ones for literally half a day. I couldn’t stick to it! But I can totally do this."

We have two reactions to this:

1. We can't believe Kim found something she won't swallow.
2. Don't try this at home, kids. It's not healthy, nor will it result in long-term weight loss. If you somehow can't resist an attempt, don't bother to give the Kardashians money as a result. Just go to Taco Bell.
