Hmmm....I started seriously limiting carbs....doing interval training 3x week, pilates, and weights...and intermittent fasting...and my blood sugar went UP...(I lost 20lbs in about 7 months)...now seem to be at a standstill...and the doc says I MUST eat SOMETHING every 3-4 hours (usually I eat raw nuts)...to prevent the spike in blood sugar. I would like my fat % to drop another 6% (lose another 10 lbs maybe, too)....but, am not sure what I’m doing wrong.
Maybe you should have picked the right parents before you were born. Just kidding, of course. The body is complex and we are stuck with the genes we were given. Sometimes there is no explanation for why "a" works for one person and not another.
My wife got a monitor on her own and measured sugar to see what was most effective and what seemed to affect her the most in either direction. That was very useful in diet adjustments and routine.
One reason for doing that was her A1C was on the high side, even after her glucose tests got to normal. The A1C by itself should not be the determining factor for a couple of interesting reasons.
