The Truth About Size Zero (2007)

With the scarily skinny silhouettes of some celebrities making the headlines, Louise Redknapp, a petite size 8, confronts the current obsession with being dangerously thin. She attempts to drop to a UK size 4, the elusive American size 0, in just 30 days. Along the way, she is subjected to a grueling boot-camp fitness regime, talks body image with one time anorexia sufferer Mel C and visits the Rhodes Farm Clinic for eating disorders, where she witnesses how lethal the current trend can be.

Unfortunately the movie The Truth About Size Zero is not yet available on HBO Max.
