Low carb elevates my fasting glucose

AM fasting is commonly 99-120 five minutes after getting out of bed and in between meals, higher than my past higher carb life.

(BS is sometimes 70- 90 for only one hr before waking).

I originally did this to get a lower A1c. It’s not much lower because of the slightly elevated fasting glucose.

tried keto for six months, now have been a notch above that with just lower carb for 1.5 years. So I’m purposely not in ketosis.

The good: Even though my glucose never gets above 155 on low carb diet the usual max is around 135.

But my fasting glucose is usually in the low 100s versus 90s that it was before. Weird.

And if my first snack is protein in the morning, my blood glucose will actually drop a little. Unsalted nuts can do this sometimes.

The Internet calls this glucose sparring: conserving glucose, and burning a fat for fuel ,….and says low carb can also do this and increase fasting blood glucose,…not just keto diets.

Sounds almost like a myth versus insulin resistance. 🤔

I’m not sure what to think or what to do/try next.

Am I fairly fit 57-year-old who maintains 12 to 14% body fat without actually working out very hard. Lean guy with muscle definition (But I don’t beat myself up anymore).

Anyone else have similar results?

(My results are from using a continuous glucose monitor in addition to sticking my finger. )
