I am happy to answer your question. As for snacking, I try to avoid snacking during the day and have only an evening snack of 15 grams of carbs or less. Often I will eat nuts, pork rinds, a low carb bar, cheese, olives, berries, veggies and dip. Twice a week, I will have a higher carb treat like popcorn or ice cream. This is what I do when I am at my best, some days are better than others. I have fallen off the low carb wagon in the past and regainned the weight but this time, I am learning that it is not as much about perfection as it is about consistency. More good choices than bad!
When I was diagnosed with type II, my doctor gave me a blood sugar meter and sent me to a diabetes education class. During the week between my diagnosis and the class, I read a lot and checked my blood sugar often. By the time I started the class, I realized that many of the foods they were telling me to eat like oatmeal and whole grain spiked my blood sugar. When I mentioned that my blood sugar was close to 200 after a bowl of no-sugar oatmeal, the diabetes educator said that my doctor would likely put me on medication or insulin to bring down the numbers. I decided that I'd rather avoid the foods that cause my blood sugar levels to rise. As for my doctor, she gave me kudos because when I returned in three months, I had taken my A1c from 9.5 to 6 then after 6 months my a1c was in the fives. My blood sugar and cholesterol numbers had improved as well and I was losing weight. I think the best way to deal with a doctor that is not on board with low carb, is to do well on the plan. It is hard to argue with results.
Another thing I would recommend is daily exercise, even just walking, does great things for your blood sugar.
