We love celebrities as much as the next fan, but when stars try to play doctor the results are not always pretty.
In their annual list, Sense About Science, a British coalition of scientists, blasts some pretty out their health ideas from pop stars, singers and one royal to-be.
Here's our 8 favorites.
Naomi Campbell always looks stunning on the runway, but according to Sense on Science, her insistence on using a cleansing diet of maple syrup, lemon and pepper is not model advice.
"It's good just to
clean out your body once in a while," she told the Daily Mail.
Not exactly, says dietitian Anna Raymond.
"It's not cleaning
your body - it's starving it!" she says. "A severe diet might actually
lead to the creation of
potentially harmful chemicals
called ketones as a result of
changes in your metabolism."

Olivia Newton-John may be famous for "getting physical," but according to Sense About Science, her theories that digestive enzymes help with food and South American plant tonics boost the immune system are way off base.
body makes all the enzymes
you need, in the right place, at the right time," says Dr. Melita Gordon, a gastroenterologist.
As for the immune boosters, immunologist Dr. Helen Lock says "Your immune system cannot be 'boosted.' As long as you
are generally fit and well, the
immune system is more than
capable of fighting disease."

British pop star Sarah Harding knows how to belt a tune, but her theory that putting charcoal on food absorbs "all the bad damaging stuff in the body" won't make it to the top of the health charts.
"Charcoal is known to absorb
toxic molecules when used
in gas masks and in sewage
treatment," says chemical scientist Dr. John Emsley. "However, it is
unnecessary when it comes
to diet because the body
is already quite capable of
removing any 'bad, damaging
stuff ' it encounters in ordinary consumption.

British pops singer Cheryl Cole has become a fashion icon across the pond, but let's hope her adoption of the blood type diet stays out of style.
Cole told Hello! magazine that the diet, which has different food plans depending on blood type, has improved her shape and energy levels.
"Your blood group cannot affect
digestion or the way food is
broken down," says dietitian Sian Porter. "This theory
is really just another spin on
reducing overall calorie intake."

Kate Middleton may have nabbed a prince, but let's hope her affection for Power Balance, a hologram- embedded silicon bracelet that promises increased strength and energy, never makes it to the commoners.

Shaquille O'Neal is a three-time NBA champion, so it's not clear why he needs a hologram bracelet. But according to the Guardian, the big man attributed at least one NBA victory to it's magical powers.

British actress Kate Ford believes magnets helped her lose baby weight. That's if you believe British tabloid "News of the World."
True or not, let's hope her fans aren't magnetically drawn to the idea.
"Wearing the magnet might
have helped to strengthen your
resolve to lose weight," said medical professor Edzard Ernst. "But it is
unlikely to have had much of
an effect on your body beyond

In 2010, extreme fighter Alex Reid had less than knockout advice for his fans.
"It's actually very good for a man to
have unprotected sex as long as he doesn't
ejaculate," he said on his British reality show. "Because I believe that all that
semen has a lot of nutrition. A tablespoon
of semen has your equivalent of steak eggs,
lemons and oranges. I am reabsorbing it into
my body and it makes me go raaaaahh."
Where to start. First, sperm is not reabsorbed into the body and has a very small amount of nutritional value, says reproductive research professor John Aplin. More importantly, unprotected sex can be a shortcut for sexually transmitted disease.
