My husband was recently diagnosed with type II diabetes. We have cut out a lot carbs and only enjoy bread and pasta as an occasional rare treat. For cheeseburgers I make cheeseburger salads. I tear up lettuce (I like to use the mixed greens that have baby spinach in them) add tomatoes, sliced half sour pickles and a little bit of sweet onion (yeah onions are one of the bad veggies). I make a dressing out of 1 tablespoon each of mayo, the half sour pickle juice, dijon mustard and Heinz 57 sauce which we share between the two salads. I cook the hamburger and then cut it up into bite size pieces and lay on top of the salad. We both love it and don't miss the bun one tiny bit.
I substitute sweet potato fries for french fries and make them myself by slicing thin like a chip and then spraying with pam or olive oil in a mister and roast in a 450 oven. You have to watch them carefully because they go from just right to burnt in no time flat.
Things like fajitas, we limit ourselves to one tortilla but have extra filling.
I have looked into the keto diet but I freely admit I am addicted to certain carbs and can't stay on it. I was the same with Atkins which is very similar to Keto.
