Thanks for your replies. I guess your right about the reading but there is still that problem of being properly objective when i'm not an expert. As for books, has anyone read "life without bread"? If so, are there any better books than that in terms of evidence? The book is very convincing and uses a lot of scientific theory and evidence (which i assume is true) to back up its claims.

Also which is the best plan to follow? Do they vary much? Has anyone tried the life without bread plan? Which plan is the least restrictive to follow? Thanks again.

p.s. can anyone explain the healthy rural chinese japenese thingy ( i know they are short but they live a long time)?
