Question about sugar level

Taas sugar ko based sa ogtt ko. I was advised to take insulin pero di ko ginawa. From 143 fasting blood sugar, I was able to lower it to 67 at first manual check using my personal glucometer. Low carb diet ginawa ko. No rice, no bread, sweets, no carbs or at least ulam lang talaga. Nagsteam ako ng puto made of almond and coconut flour, nagttake din ng chia seeds. Check mo sa fb may low carb group dun.
