Have you been given any advice by your health care team?
My choice of control for T2 diabetes is severe restriction of carbohydrates. I avoid, bread, other baked goods, potatoes, pasta, rice and breakfast cereals.
I eat meat, poultry, fish, eggs, cheese and green vegetables with a bit of fruit. I eat butter and cream, because I don't worry about fats.
Examples
B/fast
2 scrambled eggs( done in the microwave for speed)
2 or3 dried apricots
lunch
cold meat and mixed salad
Natural full fat greeek yogurt with a few blueberries and raspberries.
dinner
Home made beef burger
broccoli
carrots
apple
