Does your meter say it is OK? That is the test - on the amounts I am eating I usually stay below normal levels after meals - it is the fasting levels which say I am diabetic. However, I am losing weight - a bit wobbly but I think that there are various things going on all at the same time so I can't keep it as consistent as I could in the decades before the diagnosis of diabetes. I think that aiming for 2lb a week will be fine for me.
Some people struggle to lose half that on half what I eat if they are resistant to losing weight, I am not at all resistant - much to my shock and amazement and after so many failed diets - cut out the carb and see weight drop off without effort. That is why you need to see what is happening to your BG and your weight at any level of carbs you work to - though I also find that I can't eat some types of carb even in small amounts as it elevates BG for about 16 hours, not just a spike, and stops weightloss completely.
