I had 2 stalls...One at 3 weeks, and one at 6 weeks. Each time, I slowly increased my calorie count, and the stall broke. I am at 850-1,000 calories now and losing about 2-3 pounds per week on average. Stalls suck, I know. However, this is a chance for your body to catch up with all of the physical and hormonal changes you have gone through.
Keep doing what you are doing and the stall will eventually break. In the meantime, you should still be losing inches. Also, stay off of the scale if it helps. That evil thing has caused me to binge on many occasions pre-surgery. Two or three weeks of staying the same weight or gaining weight can reek havoc on your mindset.
Stay strong my friends.
