Hi I'm new to this. Recently been told I'm pre-diabetic. I have been cecking my glucose levels in the morning, before lunch and 90min after. My glucose is between 4.4 and 5.2 before and 90min after lunch but for some reason it's between 5.8 and 6.2 when fasting. When I eat cereals it's the Nestlé shreded wheat wich is low in sugar with skinny milk but mostly it's soup (no potatoes) or salads. Anyone has any idea why?
