Celebrity Size 00

S1 E5: As rail thin celebrities are increasingly under the media spotlight, Extreme: Celebrity Size 00 examines the new wave of super skinny stars and attempts to unravel the reasons behind their obsessive dieting. Part One concentrates on the world of modelling as the debate rages over the pressure on models to be a Size Zero, with some fashion shows banning models with a Body Mass Index of less than 18. If this went industry wide, models like Kimberly Stewart, Kate Moss and Eva Herzigova would find themselves out of work. But where do we draw the line - what's the difference between a naturally slender frame and a life threatening eating disorder? Part Two takes a look at the pressure facing young Hollywood. Mischa Barton, Kate Bosworth, Keira Knightly and Kate Hudson have all been seen looking shockingly thin. We'll discover how peer pressure from super-thin celebrity friends can affect the young stars of today. In Part Three we reveal how many women in the music industry are struggling with their weight.
