Dr Michael Greger hates diet books. He says so in the first few pages of his diet book.

Despite this, the US doctor and author of international bestseller How Not To Die says the amount of misinformation about our food and how it affects our body was what inspired him to write his new title: How Not To Diet.

"The weight loss industry is so corrupted," Dr Greger says over the phone. "No one knows squat."

In his latest endeavour, How Not To Diet, Dr Greger, known for donating all proceeds from his books and speaking engagements to charity, compiles what he terms the "ideal weight loss diet", backed up by over 5000 academic citations (at 570 pages long, he jokes that when his publisher told him people like diet books to look like they want to look post-diet – slim – he refused).
