Thanks very much for the replies. This is really useful information.
From my US survey, there was an even greater emphasis on blood glucose control. What surprised me was how many people said that good BG control (using the right priciples, not an increase in medications) had helped them lose weight. Wow! For me, that is really important, and offers hope to a lot of people.
Trouble is, while the ADA, Diabetes UK and most doctors and dieticians remain wedded to a high carb diet, it may be difficult to convince people to change to a lower level.
More anon...
