I don't need to - I avoid eating the carb dense foods the supermarkets want us to buy and the so called expert dieticians and HCPs advise are essential for good health and I get BG levels under 6 mmol/l after meals.
I have a freezer full of meat and fish and low carb veges, and berry mixtures, and two fridges stuffed with salad and veges, cream eggs cheese coleslaw - and the odd bar of high cocoa chocolate.
If the food wasn't so nice I could try to feel hard done by, but I just have to go with very very lucky.
