'tis not the sweeties with type 2 (although of course tonnes of sugar isn't good) - it's the empty carbs that will **** with your blood sugar. More protein, more fat, less stuffing your belly with bulk bread/pasta/potatoes and you can still enjoy 2 sugars in your coffee.
I like to harp on about this occasionally
.
I'm not a low-carb advocate but
make sure your carbs are good ones - fruit, green veg, etc.
Honestly the best diet advice I can give and you don't need a guide or a book for it. "Cut the bulky crappy starchy carbs, eat more fresh veg instead". It's that simple.
Also helps with bloat and achy joints (the latter was the main reason I looked into it, my joints are genetically - to be blunt - pish).
