I've had T1 diabetes for over 54 years now. I've been on low carb, moderately high fat diet for over 5 weeks now and have lost almost nothing. My clothes don't seem to be any looser and I'm getting rather frustrated. My blood sugars are much better, but still not perfect, despite working on basals and boluses. I have gastroparesis, so I can't keep to Dr. Bernstein's goal of 83. My target blood sugar is 100. I think an A1c of 4.9 is unreasonable for me, too. I would like to lose about 20 pounds.
