Hello,
I am no expert, and every person is different. However, my doctor gave me a few guidelines which helped me a lot. Maybe they will help you, too.
Instead of obsessing about so much about carbs (except refined ones), obsess instead about portions and the frequency you eat.
Eat tiny portions very frequently. The example he gave was a bagel for breakfast: Instead of eating a full bagel and then eating somethng else in two hours, cut the bagel in 4, and eat a quarter of it every half-hour. It will take two hour to eat breakfast, but the blood sugar wont spike.
Always eat protein with carbohydrates. So put (unsweetened) peanut butter on that bagel!
I hardly eat meals now. I eat a small "meal" at dinner, but during the day I "graze". I hate to cook, which compounds the 'meal" issue. Some good grazing foods I have found that are high-protein:
edamame and other soy products (if you can tolerate soy)
A few whole-wheat crackers with peanut butter
Buy some good quality burgers (100% beef or turkey) and cook them. They can be stored in the fridge to heat and serve with some veggies.
Raw vegtables are excellent keep on hand to snack on. If I was creative, I could probably make a great high-protein tofu dip for them, but I'm not.
Hard-boiled eggs. Keep a few in the fridge.
I hope this helps.
