Taken it too far: Peaches Geldof has sparked controversy by boasting about the dangerous diet which has caused such dramatic weight loss
Worryingly thin Peaches Geldof has drawn damning criticism for almost boasting about how she has achieved her dramatic weight loss.
The 22-year-old has described how she can lose ten pounds by living off nothing but vegetable juice for a month.
One dietician called the starlet 'braindead' and said she is risking 'acute cardiac arrest.'
According to OK! magazine, Peaches said: 'I do juicing. You juice vegetables and then you drink it three times a day. It's gross. I do it usually for about a month.'
'I have no willpower but with the juicing I'm like, 'I have to do it because I have to lose this extra ten pounds.'
Providing little reassurance that she has a healthy attitude to food, she added: 'I will lose it then I'm back going mental for the chips.'
'I'll juice and then I eat chips.'
Malnourished: Dieticians have slammed Peaches' extreme diet of vegetable juice, seen right in 2009
Peaches appears to have lost a tremendous amount of weight already, worrying fans with reports of dining on miso soup and little else.
And in recent months, admitted she still has days when she wakes up and thinks 'I'm so fat.'
She attempted to provide some reassurance that her dieting is not out of control in August by tweeting: 'To those telling me I look skinny and to eat something, I can assure you I've just cut out eating crap.
'I still eat like a horse.'

'Sometimes it's hard. If you open any high-fashion magazine, the girls in it are stick-thin and then they've been airbrushed down to the point where it's just ludicrousness,' she said, the Sun reports.
'I have days when I wake up and think, 'I'm so fat.'
Cath Collins, a spokeswoman for the British Dietetic Association, told The Sun: 'Peaches joins a long line of celebs who are braindead when it comes to nutrition.'
'Surviving on fruit is a very dangerous diet.'
'Peaches is at high risk of electrolyte abnormalities which could lead to acute cardiac arrest.'
'Rapid dieting like this not only makes you lose muscle strength but wastes away your internal organs.'
Worrying: Despite being extremely slender, Peaches has admitted that she still feels fat sometimes
'It is what kills anorexics. It is a stupid approach and it is irresponsible to promote this sort of disordered eating.'
'It's worrying that somebody who has money and access to contacts would pick such a ridiculous way to diet.'
Peaches showed off her waif-like physique at The Girl With The Dragon Tattoo premiere at the Odeon in Leicester Square on Monday.
She cuddled up to her rock singer boyfriend Thomas Cohen as she posed on the red carpet- displaying her brand new engagement ring.
Hard to swallow: Peaches claims that she binges on chips after a period of dieting, but her figure says otherwise
