I have type II diabetes, and used to take oral medications and insulin shots, but now I control it with diet alone. I follow something like phase 1 of the South Beach diet, with a lot of "buts." I lost fifty lbs in the first six months of eating this way.
In general, I avoid all high glycemic vegetables, fruit, grain and grain products, sugar and other caloric sweeteners. I also limit the amount of dairy I consume, because lactose spikes my glucose levels a lot. The exceptions are that I do eat whole quinoa, on occasion, and I eat berries and melons as a treat, in season only.
Breakfast is almost always eggs with some sauteed vegetables, like zucchinis and peppers, usually with some tabasco or chipotle sauce. On the weekends I will occasionally make turkey bacon too, or an omelet or fritatta. Now and then I eat yogurt for breakfast, either Nancy's plain, with walnuts and in season berries, or with some sweetener like splenda or stevia. Occasionally I buy commercially artificially sweetened yogurt. It's not the best product on earth, but it comes in different flavors, hits the sweet spot, and topped with nuts it is dessert. Ok in my heart of hearts, maybe I do think it's the best thing on earth, lol.
I keep original Fiber One cereal on hand, as well, and eat it for breakfast maybe once or twice a month, with almond milk (very low carb milk substitute). The cereal has 25 grams of carbs in a half cup serving, but 14 of those are fiber, so it's really not too bad, especially since the fiber helps even out your blood sugar levels. Mostly I use the cereal in things that need a starchy binding agent, like mealoaf.
Lunches are often leftovers from dinner the night before, or salads, or soup.
chili (south beach allows beans, and I'm glad to have them!)
beef stew with vegetables, minus potatoes (carrots, onions, green beans, zucchini, cabbage etc)
zucchini "noodles" with pesto or marinara or ground beef sauce
grilled veggie kabobs with marinated mushrooms
any meat on the grill, marinated instead of bbq sauce
sausages sauteed with onions and peppers, and home-made saurkraut
meatloaf and pureed steamed cauliflower (use fiber cereal or quinoa for starch in meatloaf)
middle-eastern spiced meaballs or roasted chicken with yogurt or kefir-cuke salad
chicken, garbanzo or veggies with jarred curry sauce and yogurt
minestrone soup minus the noodles
pot roast with mashed cauliflower
hot cocoa made with artificial sweetener (I know, I know
) and almond milk
tea with almond milk and sweetener (chai is my fave)
ricotta cheese, with artificial sweetener and cocoa stirred in, or sometimes with almond extract stirred in. Sometimes I brown almond slivers in a bit of butter to pour over the top.
Baja fresh burrito served "bare style" with no rice (essentially fajita salad)
veggie and hummus tray
chili rellenos (there may be a small amount of flour in the batter, but usually not enough to worry me...just avoid the chips and salsa lol)
stir-fried foods at chinese places, with egg drop soup
sashimi salad with edamame
sometimes in a hurry I will stop at a grocery store deli and get sliced meats and cheeses, or some hard boiled eggs!
