I am on day four of my diet, which consists of 90% fat and 10% protein. I am only supposed to stay on it for five days before allowing myself proteins and 20 grams of carbs daily. I have been checking my blood glucose levels every four hours and got so close to being low enough this morning. I came in at 4.1mmol/L (74/dl). I then went to the gym and did an hours worth of cardio, ate nothing, and came home and tested myself. My glucose came in at 5.4mmol/L (97mg/dl).
How in the heck can this be? I ate no sugars or carbs. I do have keto sticks and they always show negative. Does anyone have any knowledge about this at all? I am an insulin resistant diabetic, can this be why my blood sugar is not dropping low enough?
