Mine is at 9 hard to get it down. Specially when I can aford the foods I'm suposto have.
I understand about the high cost of food, and often healthier choices are more expensive (fresh veggies, meat, cheese vs bread, rice, pasta.) However - I've found that even though individual items are more expensive for me now, that I'm not spending more on my groceries.
In my case, I ate way too many carbs, and the volume of food I ate was much greater than it is now. I get more calories from fat and protein so I eat less. You might think about checking what you actually spend and what you could get for that money if you made healthier choices for a diabetic.
I'm also losing weight while eating all this fat, so that's a bonus!
