I started low carb 3 weeks ago and it is not going well. In 3 weeks I have lost 3 llbs and nothing in the past week. I have cut out sugar but maybe I am eating too many carbs? I noticed yesterday that I tested 2 hours after my lunch and had a level of 5,2 then tested 2 hours after that it had gone up to 6.2. I hadn't eaten anything and had only had a mug of tea with soya milk. Am I testing too early at 2 hours or would the tea and soya milk affect my levels?
