I will study net carbs because I haven't gone into that issue when planning my meals. So I really am ignorant about it. The nutritionist said to count the carbs and don't go over 10 to 12 each day. That worked for a few years and I lost weight at first, but now it is not low enough carbs or something else is not balanced. Of course, I am older and need less food, I think. The big problem is that I have no energy to do work.
