For a 2 or 3 week stall, I wouldn't panic too much... if it lasts much longer than that, then I think you should probably change up your routine-- switch up the exercise program, revisit the Pouch Rules and make sure you're not slipping/cheating, etc.
For the last few months, I've started losing in "steps" as my nutritionist calls it... I'll lose nothing for 2 or 3 weeks, then WHAMMO, I'll lose 3-4 pounds out of nowhere, another few pounds the next week, then NOTHING again for 2-3 weeks. It's been going this way for at least 4 months now; I keep track of the weight loss on the Thinner Self chart, and it's so funny-- a definite pattern has emerged!!
Seeing it as a pattern has made the no-loss weeks easier to deal with... but I agree, a great big BOOO to the scale when it refuses to budge!!
