My doctor had told me that i am Glucose Intolerance and i have been trying to change my diet. She advised me to watch my sugar intake so did a no carb diet and i was feeling ok than i started getting the shakes again so i would eat just a little bit of carbs than after some time of doing that i would get the shakes again and i am not sure what to eat and not to eat and how to handle it. i also take this medicine ongylza and some days i am fine and some days i am not. I need help with a diet please. I am trying a high protein diet and eating less but more often and it was working for a little bit but now i am back to getting the shakes and feeling like i am going to pass out.
