I'm A 54-year Old Male, Weigh 128 Pounds, And Am

I'm a 54-year old male, weigh 128 pounds, and am 5'7" barefoot. My last A1C test was 5.8. I stopped eating sugar and starch and my weight came down to 125 from about 140 to 145. My weight doesn't vary more than a few pounds from 125. Now, whenever I eat a 1.5 ounce bag of almonds, I get dizzy. It feels like a low blood sugar attack. Could this be what's happening or am I raising my blood sugar when I eat almonds? I don't have any other symptoms.
