Technically you aren't stalled until you've had no weight or inches lost for 6 weeks. Sometimes our bodies decide to take a track of their own and stop weight loss. This is normal (as frustrating as it is). Before taking drastic steps, you may want to give yourself another couple of weeks to see if things start moving again. It took me five months to get back to losing--but all the time I stuck with low-carbing knowing the good it was doing my body (yes, I wanted to give up several times but couldn't see any good incentive to do that), and ultimately the weight started moving again.
