Illusionist DAVID BLAINE shed a quarter of his body weight in his notorious Perspex box stunt in London, 2003, a medical report has revealed.

The zany showman also displayed signs of liver impairment and extreme vitamin deficiency after his 44-day fast suspended in a clear box above the River Thames - a characteristic of long-term starvation.

Blaine's shocking medical notes have been made public in a letter to the New England Journal of Medicine from his doctors.

The medical team admit they are grateful to the American, who has also been buried alive for seven days and spent 61 hours encased in ice, for the light he has shed on the effects of food deprivation.
