I started keto some 9 months ago and started monitoring my fbs each morning. After losing weight (5Kg) I started noticing that my fbs started increasing from 5 to 9. I went to Docs and was told I am now type 2 diabetic. I have now ditched keto and started eating more carbs and my fbs has fallen to 4.9 (below type 2 range). Can anyone explain why this might have happened as it seems completely at odds with the keto theory?
