14 Of The Weirdest Diet Tricks Celebrities Swear By

Ah, aging. What's a star to do when she notices that her morning wrinkles are getting more persistent with time? Look to Japan for some age-defying beauty hacks, of course. Olivia Munn recently noted to the Cut that she eats Japanese potatoes for the fitness and aging benefits, saying, "I get my potatoes from a Japanese market. I'll take one sweet potato, slice it into one-inch-thick slices, and then dust it with olive oil and cinnamon, put it in the oven, and do that as dessert. I'll eat those as often as I can — a couple every day. I know there are vitamins or supplements with hyaluronic acid, but I didn't feel like I saw as much of a difference as I did getting it from the natural source." Beats splurging on an expensive night cream, we suppose. Photo: Getty

A health plan supported by grandmothers everywhere is Sarah Michelle Gellar's cabbage soup diet, a seven-day cleanse with cabbage as its main source of nutrients. The diet does allow for other small food items, but the main focus is the low-calorie vegetable which stars claim helps them lose weight on a time crunch. Photo: Getty

Is there any problem that coconut oil can't solve? Jury's still out on that one, but take Miranda Kerr's advice as food for thought: The supermodel takes a spoonful of unrefined coconut oil with food every day to combat bloating and speed up digestion. Photo: Getty

'90s icon Liv Tyler has been around the block more than a few times in Hollywood, so naturally, you listen up when she reveals one of her unsung wellness and beauty heroes. Wait for it: cold showers. Tyler once noted that "a hairstylist friend told me [it] closes the hair cuticle...and I always feel like it makes you a little bit skinnier." Photo: Getty

We may already know Reese Witherspoon's secret to fitting in her Legally Blonde clothes 15 years later. The Southern Belle, along with Gwyneth Paltrow and Jennifer Aniston, has been linked to a diet of baby food in the past. The little vitamin-rich jars allow for a low-calorie diet that presumably helps you resist overeating. Hmmm. Photo: Getty

Definitely one of the most creative diets of the bunch, Christina Aguilera opts for one that allows her to make colorful choices. Literally. The 7-Day Color Diet only allows you to eat food of one color per day, as follows: white, red, green, orange, purple, yellow, etc. Bigger question: Does a cheese puff count as orange? Photo: Getty

Megan Fox is the bravest of us all when it comes to "beauty is pain." The Transformers star reportedly takes a shot of apple cider vinegar (the smell! the taste!) every morning to support digestion. Photo: Getty

Chanel and Fendi designer Karl Lagerfeld always looks the picture of chic, but how does he maintain such a svelte figure? Lagerfeld told Harper's Bazaar that he relies on chocolate-flavored protein shakes, steamed apples, and bottles upon bottles of Diet Coke every day to keep him in tip-top form. We can't be certain of the health benefits there, but if it boosts his creative process in the couture arena, we're here for it. Photo: Getty

Keeping up a ballerina body sounds just about as fun as it sounds. As Portman relayed during press for Black Swan, she survived on a diet of almonds and carrots to lose 20 pounds for the movie. Ouch. Photo: Getty

Madge looks directly to the moon for guidance on her food intake, as prescribed by the Lunar Diet she follows. Known as the Werewolf Plan, the liquid cleanse involves only ingesting water or juice when it's a full moon or new moon. The Queen of Pop also swears by sea vegetables, a salty diet including different types of seaweed that are supposed to be rich in fiber. Photo: Getty

Jersey Shore star Snooki took the dream route for keeping off baby weight during her pregnancy by opting for a diet of...cookies. Yep, Dr. Siegal's Cookie Diet apparently allowed her to make the most of sugar cravings during the day with six of his special cookies en lieu of breakfast and lunch, followed by a healthy dinner of chicken or fish.

Even though Beyoncé's known for her curves, she once made headlines for the Master Cleanse liquid diet that she used to lose weight for Dreamgirls. Known as the "Lemonade" diet, the Master Cleanse recommends an elixir consisting of water, lemon juice, maple syrup, and cayenne pepper. For now, she seems to have sworn off juice cleanses in favor of temporary veganism, which eliminates all animal products from your diet. Photo: Getty

One diet trick we could really get behind if it actually works is Lady Gaga's fabulous drunk diet consisting of, well, whiskey when you want it and carb-less meals. This pop star treatment also recommends working out while hungover, so we hope you've got the stomach for it. Photo: Getty

Goop queen Gwyneth Paltrow is never shy about disclosing her life and health tips, and she claims that she owes her healthy figure to an allergy-combating and digestion-boosting Elimination Diet. The regimen cuts foods like gluten, dairy, and red meat from your diet (*sigh*) and the cleanse lasts all of 21 days, but beauty is pain, right? Photo: Getty
