Ketostix can be very unreliable. Especially if you drink a lot of water or are on TOM. You should be showing some loss at 2 weeks though. Even if only 2-4 pounds.

If your weight loss hasn't improved, maybe you need another lc program. Check out some of the other threads on the boards and read some of the books to see if you match any of the profiles.

Sometimes it takes a little searching to find the lc program that's right for your body's chemistry.

Good Luck.
