*sigh* Ketostix are one of those things that I think make low carbing a pain in the A$$! Mostly because, they don't seem very accurate to me. Anyways, the amount of protein you have, the type of protein, and even time of day and amount of liquid can affect the results. So, like you said, I'd just ignore them and go on. The best I can really tell you is that every person's body is different and will work best on it's own levels. This may be the case. For you, your body may work the best at 35g. of carbs. I have to say mine does, too. I know I can lose at higher, but it is SLOW. But my body works best under 40.
