Are you perhaps consuming low carb bars and shakes?

Without a journal, it is hard to help you since we do not know what you have consumed over the past few weeks.

Why not start one up today and list out what foods you consume on a daily basis. Then maybe we can help you out

Those strips are nice however there are a ton of things that affect them.

Such as:
1) daily water consumption
2) exercise
3) age of the strips
4) moisture exposure (aka being in the bathroom where you take showers)

I have had a bottle of strips since I started back in April of last year. I decided to test the other day. Mine didn't turn pink....and I know I am in ketosis due to monitoring my carb counts.

So don't fret too much overr those things. You may have just gotten a bad bottle.
