It is no secret that celebrities have more pressure than the average person to look perfect at all times. They have to deal with paparazzi that pop out of bushes to snap random pictures of them when they leave their cars. If the photo is taken at a bad angle, they can be certain it will be plastered online, or worse yet, on the cover of a tabloid magazine. So it may not be too surprising that many resort to bizarre (and unhealthy) measures to lose weight-quickly. Check out some of these extreme celebrity diets.

Grapefruit Oil Diet

While grapefruits are one of the world’s healthiest foods, containing an excellent source of vitamin C which supports the immune system, did you know that smelling the fruit is also reportedly beneficial? Diva Jennifer Lopez carries a vial of grapefruit oil and sniffs it. The aroma allegedly affects liver enzymes and promotes weight loss.

Baby Food Diet

Celebrities such as Jennifer Aniston and Reese Witherspoon are reportedly fans of this unique diet. This lose-weight-quick fad diet is just as delicious as it sounds. Followers of this diet eat only jars of baby food, in addition to a “healthy” dinner. 14 servings of baby food equal approximately 1,000 calories, which would result in weight loss.

Air Diet

Back in 2010, French magazine Grazia named the “air diet” as the “it” way to lose weight. Madonna was linked to this fad diet promoted by the French after she, in addition to other celebrities, were featured in a Dolce & Gabbana campaign, holding food to their mouths, but not consuming it. There is only one rule: Eat nothing but a water and salt soup concoction. The concept comes from Breatharianism, which is the belief that one can live only on energy from sunlight, and do not need nourishment from food.

Cabbage Soup Diet

Actress Sarah Michelle Gellar has been linked to the cabbage soup diet, which calls into question how she had enough energy for her power-filled defense moves on “Buffy the Vampire Slayer.” This diet involves plenty of cabbage, green onions, green peppers, diced tomatoes, carrots, celery, chicken soup mix, and V-8 juice. Other supplements include cranberry juice and black coffee. Then for the next seven days, you eat all the cabbage soup you want. This temporary diet has been used primarily to kick start a weight loss plan which hopefully involves more food.

Ice-Cube Diet

Apparently ice tastes just as good as food. Renee Zellweger, who is as well known for her movie roles as she is for her weight, took on this extreme diet. It involves eating ice cubes throughout the day to curb hunger. “As long as I get that ‘constant feed’ feeling, it’s semi-tolerable,” she has been quoted as saying about the bizarre “food” choice.

Coconut Oil Diet

Coconut oil is a great way to make hair and skin soft and healthy, but did you know you could also eat it? Supermodel Miranda Kerr has claimed that the oil is what keeps her so slim. She ingests four tablespoons a day, either by putting in on salads, cooking with it, or putting it in her cups of green tea.
