Could be. I tried low calorie, I cut fat, counted the calories, and did it that way. Purely personal, but I had read a lot on here that sometimes LCHF reduces BG, but still can have higher fasting levels, and they're the last to drop. I also subscribed to the idea that your body goes into 'repair' mode during fasting, so wanted to make sure my pancreas and liver were getting exercised, and didn't get overlooked in the process. I had a meter, so watched the results of what I ate daily. I must admit, it suited me, and it did seem to work for me. Another thing I noticed, if I do drop the carbs, my fasting goes up. I suspect I have a liver dump in the morning, and if I LC, it catches me out, if I don't LC, my pancreas is already 'turned on', and waiting as it were.
