Angelina Jolie is reportedly risking her health - and that of her twins - in a bid to ditch her pregnancy pounds in record time.

The mum-of-six appears to have already regained her former svelte figure since giving birth to Knox and Vivienne in July.

And, according to a US report, her dramatic weight loss is the result of limiting herself to tiny food portions and gruelling workouts.

An insider tells In Touch, "She's been eating three to four tiny meals and working out for an hour or more every day."

But it's not only Angelina's health that could be at risk - the twins need their mother's breast milk to be as fatty as possible in order to develop properly.

Family physician Dr. Walt Larimore adds, "If someone is taking in fewer calories, their nutrition level is dangerously low.

"She'll have vitamin and mineral deficiencies."   

Let's hope Angie ditches the diet soon.
