The book cover yes covers are for both sides of books does not mention symptoms and we have a highquality secondary source explaining the claims it makes Your wish to attenuate the quack claims made for the diet is not neutral Gotschalls selfpublished book is not a reliable source for anything much that is worth mentioning There may be a case for having a WPEL for it I am always happy to consider specific proposals rooted in sources and WPs guidelines  policy but unless there are new sources I am not persuaded we should waterdown our wellsourced account of the claims made for the diet
