The Weirdest Diet Tricks Celebrities Swear By

Iiiiiiiinteresting.

It's tougher than ever for celebrities to live and age under the scrutiny of public pressure, if their continual body-shaming is any evidence. And while some claim to eat cheeseburgers and work out whenever they feel like it, others are taking...unconventional means to trim their waists. Japanese potatoes? Baby food? Whiskey? Ahead, some of the strangest fad diets and anti-aging hacks stars have ever tried.

Jennifer Lopez

We're big fans of essential oils for their healing benefits, but according to the Blackbook of Celebrity Diet Secrets, stars like J.Lo take it one step further by seeking out grapefruit essence to lose weight.

The multi-hyphenate singer/actress/producer regularly takes whiffs from a vial of the fruit-based oil, which some believe affects the liver enzymes and promotes weight loss.

Heidi Klum

Another tidbit from the Blackbook of Celebrity Diet Secrets and the Epsom Salt spokesman himself is that supermodel Heidi Klum looks to epsom salts to keep her as trim as possible on the red carpet. She apparently soaks in a bath full of them before events in order to reduce bloating and draw out excess fluids.

The naturally occurring mineral is also purported to ease migraines, improve sleep, and flush toxins from the body—for what its worth—according to the Epsom Salt Industry Council.

Renée Zellweger

She's now (unfairly) become the poster girl for the lengths women in Hollywood are pressured to go to in order to maintain their aging faces and figures, but years ago Zellweger foreshadowed this by saying that one fool-proof way to keep off weight is by simply eating ice cubes.

Though there's no real nutritional value there (besides it being, well, water), she was quoted as saying "As long as I get that 'constant feed' feeling, it's semi-tolerable." Oof.

Victoria Beckham

They say that snacking throughout the day is supposed to make you feel fuller without consuming as many calories, which the former Spice Girl Victoria Beckham took to heart after giving birth to her daughter Harper Seven. To slim back down post-baby, she cut out sugar from her diet and adapted the "Five Hands" meal plan that prescribes snacking on five palm-sized amounts of high-protein foods like salmon, yellowfish tuna sushi, and scrambled eggs in a day.

Hugh Jackman

Hugh Jackman's had his fair share of challenging movie roles that required him to either bulk up or lose a bunch of weight all at once—from his "starvation diet" for the harrowed Jean Valjean role in Les Miserables to his beefy recurring mutant role as Wolverine.

In order to gain more muscle weight for the job, he toldEntertainment Weekly that he packed on the protein (unsalted chicken and spinach), though his eating schedule was more...unorthodox. Called the "16-8 Diet," Jackman would fast for 16 hours of the day and then eat 5,000 calories in eight hours (about twice the recommended daily amount for men).

Beyoncé

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.

Lady Gaga

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 just hope you've got the stomach for it.

Gwyneth Paltrow

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?

Olivia Munn

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.

Sarah Michelle Gellar

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.

Miranda Kerr

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.

Liv Tyler

'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."

Reese Witherspoon

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.

Christina Aguilera

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?

Megan Fox

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.

Karl Lagerfeld

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.

Natalie Portman

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.

Madonna

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 has also come under fire for following an "air diet" promoted by Italian magazine Grazia as the "It" diet which simply involves bringing a plate of food close to your mouth, inhaling the food, and putting it back down. Hmmmm.

Snooki

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.
