Being a celebrity is no easy job, especially when it comes to maintaining a fit physique! Many celebs even turn to ridiculously extreme and dangerous dietary measures in order to achieve their ideal weight and health goals. If you’re not a celebrity, then grab some pizza and sit back as you enjoy this list of 10 incredible celebrity diets that you probably won’t be trying anytime soon.

Beyoncé Knowles: The Master Cleanse
Shortly after Dreamgirls was released in 2006, Beyoncé Knowles went on The Oprah Winfrey Show and shared her secret to losing weight fast for her starring role. The star’s big secret was the Master Cleanse diet which helped her to lose 20 pounds in just 14 days. Unsurprisingly, the all-liquid diet of cayenne pepper and lemon water became an instant sensation after Knowles’ interview was seen across the world.

Demi Moore: The Werewolf Diet
Although she’s far more beautiful than a werewolf, Demi Moore has reportedly participated in the werewolf diet which encourages individuals to base their eating habits on the lunar calendar. Dieters on the plan can try a 24-hour juice fast during a full or new moon, or they can try the extended diet which adds a specific eating plan that corresponds to the phases of the moon cycle.

Marilyn Monroe: The Eggnog Diet
If you’re not a fan of eggnog, you may want to skip ahead to the next diet on the list! For Hollywood starlet Marilyn Monroe, a diet of raw eggs whipped in warm milk every morning helped her to maintain her knock-out figure. The recipe involved cracking 2 raw eggs into a pan of hot milk that was then stirred into a frothy breakfast beverage that would sustain her until dinnertime.

Laura Prepon: The HCG Diet
And the award for the most painful diet goes to… Laura Prepon for allowing herself to be stabbed with needles! Dieters on the HCG diet are injected with Human Chorionic Gonadotropin (HGC), a hormone which occurs naturally in the human body during pregnancy. The hormone hasn’t been shown to have any real impact on weight loss and individuals on the diet must also stick to a 500-calorie daily food intake (which is way more likely to be the reason for any loss of weight loss).

Reese Witherspoon: The Baby Food Diet
Many celebrities have been linked to this next diet including Lady Gaga, Gwyneth Paltrow and Jennifer Aniston. The Baby Food diet is perhaps the most self-explanatory of the diets on our list. The simple plan encourages dieters to replace their first two meals of the day with Gerber’s baby food, followed by a health-conscious dinner. Unsurprisingly, experts argue that the diet does not provide sufficient nutritional value for an adult although many do agree that baby food offers certain health benefits.

Madonna: The Breatharian Diet
Madonna has followed a variety of extreme diets over the years such as the macrobiotic diet, which eliminates all wheat, eggs, meats and dairy. However, trying the breatharian diet takes her “extreme diets” to a whole new level. The diet’s concept was born from breatharianism or the belief that humans can survive on sunlight alone. The diet—though limited in it’s length for obvious reasons—encourages individuals to sustain themselves with a salt and water soup concoction for optimal results.

Adriana Lima: The Victoria’s Secret Diet
If I ever need an incentive to NOT be a Victoria’s Secret model, this would definitely be the one! Adriana Lima sticks to a restrictive diet all year long to maintain her stunning physique, but it’s her crazy pre-show diet that may come as a surprise. In the nine days leading up to a Victoria’s Secret Fashion Show, Lima restricts herself to solely protein shake beverages with powdered eggs. Then 12 hours before showtime, the Brazilian beauty cuts out liquids all together! As much as I love Lima’s figure, I love food a lot more, so no thanks.

Ashton Kutcher: The Fruitarian Diet
This may be one of the most dangerous diets on the list as it sent our next celebrity to the hospital! To get into character for his role as Steve Jobs in the 2013 biopic Jobs, Kutcher decided to try a fruitarian diet which was Jobs’ preferred diet for creative boosts. Followers of the diet believe that 75% of an individual’s daily dietary intake should come from raw fruit. Just one month into the diet, Kutcher ended up in the Emergency Room with an inflamed pancreas—yikes!

Victoria Beckham: The Alkaline Diet
Former Spice Girl Victoria Beckham is a big fan of the alkaline diet which is a meal plan aimed at keeping your body’s pH between 7.35 and 7.45. In order to be alkaline-friendly, participating dieters need to follow an 80/20 rule of more vegetables and less grains and proteins. However, individuals will not be able to measure results by simply stepping on a scale with this diet! A urine test will be required in order to truly determine where the body’s pH balance levels are.

Lady Gaga: The Drunk Diet
Lady Gaga and her former boyfriend Lüc Carl have both participated in what they call the Drunk Diet. In 2012, Carl even wrote a top-rated book on the unorthodox diet. In fact, the tagline for the lighthearted memoir is “How I Lost 40 Pounds… Wasted.” The Drunk Diet is the humorous tale of Carl’s Rock ‘N Roll adventures and how he transformed a whiskey-and-5-A.M.-cheeseburger lifestyle into a successful weight-loss regime.
