My dear, it's going to be very slow going for you to lose these last few pounds. First of all, you're already quite thin, and your body may not want to lose any more weight. Second, it's supposed to take a long time to drop the last 5-10 pounds. Have you read the Atkins book section on pre-maintenence?

Just keep at it, and play with your carb counts, calories and fat percentages. The pre-maintenence phase is a learning experience. Please don't be in a hurry — you've done well so far, but the closer you get to goal, the slower the weight comes off. It's true for me, and I'm still 40 pounds away from goal!
