I prefer to eat about 30g to 50g carb daily; I don't tolerate carbohydrate well. Other forum members can happily eat as many as 150g daily, but I don't think many of us go much above that level unless we use insulin. On insulin you can adjust the dose to compensate for the amount of carbs.
If I ate the NHS RDA of carbs (230g for women) I'd weigh about 30 stone and my blood glucose levels would go through the roof. As I said, I don't tolerate carbohydrate well, so I don't eat much; why feed my body stuff it can't handle?
