I'm doing my own modified very low carb diet. I am pre-diabetic and gluten intolence runs in my family (celiac disease), so I decided to do a gluten-free, sugar-free diet. Coincidentally sugar and wheat are 100% carb so it makes sense to eliminate them 100%.
I don't eat anything with sugar--no dessert, alcohol, chocolate. I also do not use diet sugar products.
Gluten-free means no wheat, no rye or barley--I do not eat any grains at all. No bread, pancakes, bagels or pasta. (I think I miss bread the most.) I have tried various gluten-free products but I don't like the taste and also most of them substitute rice flour which is very high-carb. So I just do without.
In addition, I cut out high carb (starchy) foods such as potatoes and rice. Nothing like a baked potato or steamed rice to spike your blood sugar! I do have beans but only as tiny amounts in soups or chili--they have too many carbs and that interferes with weight loss.
What's left that I can eat? I have beef, chicken, seafood, eggs, milk, cheese, vegetables and salads, fruit and nuts. I try to have lower fat proteins because high fat equals high calories. Even though high fat doesn't affect my blood sugar, higher calories means I won't lose weight and that is a main goal right now. So I stick with lean cuts of meat instead of bacon or prime rib. I grill or saute meat and seafood--never deep fry in oil. I drink skim milk and have nonfat greek yogurt. I use lowfat mayo and part-skim cheese in recipes. I use nuts sparingly because they are calorie dense. As for fruit, I limit high fructose kinds like bananas and oranges, and instead have berries such as raspberries and blueberries. And of course I can eat unlimited vegetables and salads. My daily calories run between 1200 to 1600 but I don't count calories--I just look at ingredients.
I have been on this diet for 3 months and have lost 39 lbs. without altering any other part of my lifestyle. I lose 2-3 lbs. per week every week. My blood sugar has stabilized in the safe zone but I am still taking metformin. Eliminating carbs has really decreased my appetite so it's an easy plan to stay on. I need to add more exercise now to start toning up. Losing weight sure reveals more flabby parts!
