I have been o a low carb diet for 8-9 days at around 1400-1500 cals. After my fasting blood sugars dropped at first from about 6.5 to 5.5 first few days. I then fasted for a day at 650 cal and ate 1500 cals next day. I have been exercising on bike for an hour everyday ...about 1000 cals used...and i also walk fast for 1.5 to 2 hrs a day. So i am running a significant calorie defecit. I have dropped about 3.5kgs but last three days my blood sugar has risen 6.3 to 7.2 and 8.3. I have never scored above 7.0 before. Has anyone got an explanation or had a similar experince. I am concerned it may point to a different problem entirely
