Found this article when reading 'what doctors won't do' on the Guardian (Guardian article )

One of the things was follow a low carb diet and the doctor in question cited the following article:

'Low carbohydrate-high protein diet and incidence of cardiovascular diseases in Swedish women: prospective cohort study'

I can't see any mention of fat intake in the study (although I am skim-reading as it's work time!), but this is a large sample size.
