Anne Hathaway’s Oatmeal Paste Diet and Other Celeb Extremes

To lose weight for the role of Fantine in the upcoming film Les Misérables, Anne Hathaway took to extremes, according to a Vogue interview. Hathaway recently shared that she embarked on a super-strict oatmeal paste diet to give the appearance of dying.

Hathaway told Vogue she limited her food intake to just two thin squares of oatmeal paste per day while filming and lost 15 pounds in two weeks' time. This diet followed a 10-pound loss facilitated by a pre-filming cleanse. She described the effort as "a little nuts," and "a break with reality."

However, Hathaway isn't the only star who's gone to extremes for a part.

Beyoncé's Maple Syrup Cleanse

Motley Health describes a maple syrup and lemon juice cleanse diet Beyoncé used to prepare for her role in Dream Girls in 2006. The diet worked temporary magic, but the star regained the lost weight afterward. That's because it's not a real diet but a fast, since no food is consumed, and it's not sustainable in the long run. In 2012, after giving birth to a baby daughter, Beyoncé abandoned fad dieting in favor of setting a healthy example.

Kourtney Kardashian's Brush with Not Eating

Kourtney Kardashian simply stopped eating much of anything when she wanted to lose weight for a photo shoot after giving birth in 2010. After passing out and being taken to the hospital by ambulance, Kardashian wised up. Calling her previous dieting "obsessive," she told the Hollywood Scoop the diet wasn't worth it and she was embarrassed by her action.

Adriana Lima Alternates No Solids, No Liquids

Victoria Secret model Adriana Lima puts her body through the ringer when she's getting ready for the runway. She told the Telegraph she loses weight by consuming nothing but protein shakes for nine days, then giving up all liquids for the last 12 hours leading up to a show.

Lima described the Victoria Secret show as the highlight of her life and said the extreme dieting is worth it. But admirers should note Lima advises against the copycat dieting. People noted when Lima goes on a liquid diet, she works with a nutritionist and uses the diet for a short time frame once per year.

Angelina Jolie Reportedly Living on 600 Calories Per Day

The Daily Mail says Angelina Jolie rarely eats a full meal and has survived on as little as 600 calories per day. Unlike stars who try to diet, Jolie reportedly forgets to eat due to her frenzied lifestyle.

Dr. Melina Jampolis, a physician nutrition specialist, told CNN that extreme caloric restriction -- 800 calories or less per day -- is unsafe unless undertaken with medical supervision. She said dieters consuming less than 800 calories risk heart arrhythmias, dehydration, electrolyte imbalance, low blood pressure and high uric acid, potentially leading to gout or kidney stones.
