I have recently been diagnosed with pre-diabetes. I am now on a strict low carb diet, losing pounds nicely. I have been eating properly and walking 2 miles every day. Some days I feel great, others I feel quite fatigued. I wake up and my mmol/l is 6.5 then during the day it ranges between 7.8 and 9.9 mmol/l post lunch and then two hours later it is between 5.2 and 6.1 mmol/l??? Lately I have been experiencing pains in my lower back which seem to be the kidneys? Does anyone else have similar symptoms? Many thanks
