Hi,

I started on the Adkins diet 10 days ago. I've
been testing my urine with Ketone test strips I
purchased at GNC. The manufacturer is
LW Scientific from Tucker, Georgia, USA. For ten
days I've kept my daily carb intake below 20
grams. Each night I've tested my urine and each
night its come out negative. Two days I had
zero carbs because I was getting frustrated. I
also exercise 60 minutes on a NordicTrak each day.

Tonight, I went to Walgreens and bought Ketone
test strips manufactured by Bayer. These are used by diabetics to test for Ketones. It showed I
had a "Large" amount of Ketones! Registered 80!
At the same time I dipped the GNC test strips in
the same Urine. Came up negative again.

I don't know if I just got a bad batch or this
brand is generically defective. They have an
expiration date of Feb, 2002, so they should be
good.

Anyway, if you aren't registering any Ketones
in your urine and you think you've followed the
rules, go to a drug store and ask the pharmacist
for the Ketone test strips. Walgreens keeps them
behind the counter.
