Hi! I am an underweight pre diabete and I tried to follow a low carb diet and cut down on rice or bread but landed out to be more thinner and lost about 5 kgs.I was put on a low dose of metformin (250mg) after meals.My fasting blood sugar varies from 5.8 to 6.2. After a non low carb meal the spike can go up 10 mmol/l and after 2 hrs it can fall to 7 mmol/l.I would like to have some advice as how to prevent the 1 hr spike. thanks
