According to a new book by pop culture historian, Debra Sharon Davis, John Lennon suffered from 'food fetishes' and 'obsessions' reported RadarOnline.com.
In the book "BackStage Pass VIP" she writes that the late Beatle was always hungry and loved to eat but 'hated the feeling of being full' so he would often 'force himself to vomit' after eating, according to the Daily Mail.
The Telegaph reported that Lennon showed all the signs of the eating disorder but because he was never diagnosed with the disease, the star went untreated for most of his life.
Davis wrote that Lennon hid snacks away and fantasized about food like his favorite Rice Crispies topped with ice cream.
In her book she notes: "One must also realise that at that time the public and the media were unaware of bulimia as an addiction and health risk – which made it all the more frightening for John Lennon. He literally had no point-of-reference on what he was experiencing."
Many of the Lennon stories in the book come form interviews with with late songwriter Harry Nilsson, a close friend of Lennon. According to the auhtor, he told Davis back in the 1980's that Lennon saw his eating disorder as a sign of weakness.
The book is a collection of the new stories and secrets of the world's most famous stars including Janis Joplin and Mick Jagger, who the author claimed in the book is a conservative, desperately seeking his mother's approval.
