Are you T1, think mostly will help T2,isn't 250g around 62 spoons sugar a day not being T1 but that seems a lot. But we all react differently if you test and get no spikes guess your lucky
I’m not sure about getting it free. The book in paperback when I bought it was about £4. If you are on Facebook there are groups that will support you too. 8 week blood sugar diet friends is the group I’m in.
I eat around 250g carbs a day (sometimes more) and have an a1c of 37. Low carb works for some but isn't necessary for most. As long as the meals are carb counted that is the important thing...
Yes I did a lot of monitoring in the earlier days too - I didn't react quite as the books lead you to expect with some foods either!
Good luck then low carbs worked for me hba1c down from 64 to 48 in 3 months. Just cut all we are told is health white and brown rice n pasta, baked potatoes, wholewheat bread the lot. Seems extreme but I found it interesting adventure testing after every meal to see what raised my sugars and what I was good to eat.
