Atkins is not a quick weight loss diet. 10% after doing a strict induction, then a week or so of stall is normall. While it may be frustrating to you, the fat fast won't help.

I tried the fat fast. I made it 5 days. I was sick the entire time and felt nasty. I was also very unsatisfied. At the end of the week I was down 5 pounds. After going back on induction I gained it all back in 2 days. I stuck to strict induction and took the 5 pounds back of fin a week, but without feeling hungry or sick in the least.

Typically on this WOE you can expect to lose 10% on induction, then 5% of the remaining weight you have to lose every month after that. If you want to increase that rate, then exercise more. You are oding things right as you are now, just have more patience and let the weight come off in a healthy manner. The closer you are to goal the slower it will go, that's normall. In fact the slower you lose those last few pounds the more likely they are to stay off.
