A little over a year ago I was diagnosed with Type diabetes. Shortly afterwards I came across Michael Moseley's 8 week blood sugar diet and for the last 12 months nearly all of my meals have come from the 8 week blood sugar diet recipe book. During this period my weight has fallen from 18 stones to 15 stone four pounds and I would like to lose another stone and a half. What I cannot understand however are my blood sugar readings. My three HBA1C readings were 65 (June 2017), 41 (December 2017) and 38 (June 2018). The diabetic nurse is delighted and says that the recent readings are below those of a pre-diabetic, However, when I do a finger prick test, my fasting blood sugar level is never below 6.3. About 12 months ago it was a low 5 and sometimes 4 point something but now, is never below 6.3. Bearing in mind the HBA1C reading is there a possibility that my blood sugar tester has developed a fault?
