An expert has claimed that Angelina Jolie's diet of just 600 calories a day is a starvation diet and a prescription for disaster.
According to Jackie Keller, Founding Director of NutriFit in Los Angeles, the actress whose shockingly thin body has caused alarm should be eating more than twice that much, Radar online reported.
The 36-year-old mother of six was snapped in Vietnam this week with alarmingly skinny arms wearing a red dress that showed off the visible bones on her spine.
And Grazia magazine reported that she is sometimes subsisting on just 600 calories a day.
"Angelina has been known to start her day with little more than a spoonful of coconut oil and a handful of cereal," a source told magazine.
"The worrying thing is that she is so busy, she often forgets to eat. Sometimes she'll skip lunch altogether or will just grab a few almonds and some gummy bears while she's on the go, or will have a protein-based shake rather than anything more substantial," the source added.
Jolie, who travels around the world with her hunky beau Brad Pitt and their brood will skimp on her last meal of the day too, the magazine claimed.
"Then dinner could be something like a lean steak and a glass of red wine," it said.
If Jolie continue to restrict her calories to such an extreme, she would be facing some serious health problems, Keller warned.
"This is a starvation diet and a prescription for disaster," said Keller.
"If this is true, then it is insufficient food to maintain her overall weight as at a certain level your body goes into self-preservation mode and begins burning lean muscle tissue for fuel.
"Anything under 800 calories a day is a starvation diet and would put her in this zone.
"For her height of 5'8", a healthy weight is about 130 pounds, so she should be on 1,500 to 1,600 calories, and that's without taking into account the additional calories she needs for exercise or taking care of six children," explained Keller.
