I have a few words of advice:
~It is very common to lose for a few weeks, and then have a couple of weeks where you show none, or very little losses. For instance, I lost about 15 pounds in a one month time span, and then for the next 3 weeks, I didn't lose anything. However, if you average it out...I lost about 15 pounds in 7 weeks-an average of 2 pounds a week-but instead of it being in regular incremements, it was a couple weeks of large drops, and a couple weeks of nothing.

Not everyone loses weight at a steady even pace at every single weigh in.
~Something that I have found that makes me lose weight slower, is food that has "fake fiber" added to it. One of the things that I can think of here is WW yogurts, Fiber One yogurts, etc. I eat Yoplait Light Yogurt for 2 Points a cup (100 calories) but because of the fake fiber added to them, a similar caloried serving of WW yogurt is 1 Point...so yogurts with added fiber to them I do not eat-because it makes my calories higher...even though my Points stays the same. (Does that make sense?

)
A food with fiber in it naturally (oatmeal, fruit, vegetables, etc.) is different than a food with fiber added to it artificially.
