@Roy Batty, Lean, very fit individuals with raised blood sugars is definitely a thing. You will find a few members on the forum with in a similar situation. Like me they have tried the very low carb diet, with little success. I tried it first 9 months with very little movement in my blood sugars. I was a competitive athlete up until around 10 years ago and I still exercise. I do the equivalent of three marathons a week. I do fast walking which to be honest may as well be a slow jog. My BMI is around 19. Low triglycerides. As a matter if interest do you produce low levels of ketones all the time? My Dr stated that it is clear that my muscles are insulin sensitive and that bears out with low normal C-Peptides which I paid for.
Im not on a very low carb diet, but I do watch my carbs and I am very careful what I eat. An issue I have is if I reduce my carbs I lose weight, like it drops off me. My pants literally drop off from the weight loss, it is so significant. So I have to eat more carbs. It was the same on the very low diet, but even worse.
For sure check out the fructosamine test, that may give you a lower reading, but bear in mind for some people the ‘classic T2 loosing a few pounds and going on a very low carb diets brings their blood sugars right down. For others, particularly the fit lean types these lifestyle changes do nothing. I have managed to get my blood sugars into the normal range 5.8% but I’m on meds and I do a hell of a lot of exercise.
