This sounds pretty normal to me. I very frequently go two weeks or longer without seeing any loss on the scale. Often these periods are accompanied by some apparent readjustment of my body, in which things rearrange and my shape changes.
It would be nice if our bodies were clockwork automata that reliably shed a few ounces of weight and a few millimeters of girth every single day so that we could always have a nice, linear sense of progress. Unfortunately that isn't the reality. Too many factors determine your scale weight and the pliability of your shape on any given day, and most of those factors are outside of your control. The best you can do is be patient, think in terms of averages over time rather than day to day or week to week changes, and take a longer-term view. If you are fitting into clothes you couldn't wear a couple of weeks ago, then you are doing very well. Your plan is working and you just have to keep stick with it.
The last few pounds when you are close to a healthy weight are notoriously difficult. Over the past year my weight loss has slowed to less than half the rate it was the previous two years. I am approaching the healthy BMI range asymptotically, not linearly. That is just how it goes.
High weight: 275 (August 2009) *** Low weight: 155 (October 2012)
Today, working off a partial regain. Current weight: 179.
* Make the best choice I can make, with every choice.
* Remember that the temptation in front of me is not the last of its kind that I will ever see; say "I'll pass today."
* Say "no!" to my whiny inner five-year-old.
