You could also look at Swerve and the other sweeteners that use the “sugar alcohols”—these don’t seem to spike insulin like regular sugar.
My wife and I have cut most sugar out of our diets and we sleep better, feel better and are still not wanting. For my coffee, I put about 1/4 TSP of ground cinnamon and 1TBSP heavy cream in. Sweet, but not sugary sweet. I love it.
Congrats on your progress!
I wouldn’t stay overweight as a just in case. Find you target weight and go for that—really what makes you feel good while keeping healthy blood/cholesterol/etc numbers.
