Any negative effects from being on a low carb diet?

I would say the only negative is occasionally being hypoglycemic. I’m still getting used to the low carb diet and trying to following Dr. B’s recommendation to stay ~90mg/dl all the time, so I’m experiencing more lows than highs, actually. My doc really doesn’t like to see all those lows on my glucose meter. I personally feel more comfortable with lows than highs, I’ve always been able to take care of lows (even “super lows”) with a half a glucose tablet. Good luck!
