I have some questions for you, probably before anyone can answer your questions. Of course, your COD has probably asked you all these questions, so bear with me...
Which plan are you on (with or without lites)?
Are you exercising? If so, how many hours per week? And if yes then you might be losing inches, not pounds.
What types of foods are you eating? That is, are you eating lots of processed foods?
Are you getting your starches and fruits in before 2-3 pm?
Are you eating several mini-meals per day, vs 1-3 large meals?
Are you changing things up at all? If you have only been eating chicken, add some beef or pork to see if that helps.
Try eating citrus or melon fruits.
Try eating only starchy vegetables vs breads, pasta, etc.
Are you drinking all your water?
Try eating with the fire/kindling principle (I had this in my sent messages, but found it on this forum - so don't know who to credit):
Fire (protein, fat and dairy) and Wind (starches, veggies, and fruit - carbs!) The analogy is that fire stokes your metabolism; wind puts it out. Together, the wind fans the flame and makes your metabolism burn at its best. You can do what works for you as long as you pair the two. You don't want wind alone ever. You can do dairy alone, but that really it works best if you have a little of each to balance things out.
Of course, I thought of a couple more questions before I started my list...
