Can anyone please recommend a book explaining the physiology of processing carbs?

[Daffodilius]

Maybe @Biwi?

I bought and read one a few years ago but think I must have charity shopped it. Is anyone able to help please?

I don't know a book, but there might be articles on Diet Doctor, or under Dr Jason Fung.

it depends how complicated/scientific you want it to be @Daffodilius!

This is a really good book, but probably the most complex . I think it was written for medics.

Otherwise, The Obesity Code, by Dr Jason Fung is a good one, as is Escape the Diet Trap by Dr John Briffa.

Also worth checking out The Diet Doctor website, as @DianaT1969 mentions, and Zoe Harcombe's blog.
