Start a journal and post your meals so others can see what you are eating and maybe find some problem spots (but be sure to write it ALL down ). Maybe you need to increase your carb intake some...are you near your TOM? There are a lot of reasons you may be having trouble...including some that have absolutely nothing to do with the way you are eating. Are you under a lot of stress right now (ordering gowns, etc)? Stress can stop you from losing weight and make you gain. What kinds of meds are you on? Which Atkins book are you following?

I realize I haven't answered your original question and have asked plenty of my own, but we need more information before we can help. Don't give up...someone here will have something that you can try and just might be the key you are looking for.
