The low carb products have been wonderful for those of us who are insulin resistant or diabetic. Although we do not have to eat a carb free diet, we do need to limit the carbs we eat with each meal or snack. The low carb products made it easy for us to do so. If they fade away from the market, it will be more difficult for us to limit carbs. Not impossible, just more difficult.
Thank goodness for Splenda though. He is able to eat frozen snacks that are made with Splenda without exceeding the number of carbs he's allowed.
