Help! Just got some ketone strips from Netrition (good deal?-100 is around 7.95 from LWS brand) just tried one ( 5 PM EST) and it looks like I'm negative-a light tan/pink. Sunday will be 2 weeks on induction. Seem to be losing some inches, you know the "bloat". What's going on? Carbs are staying at 20-21 (depending on green tea, decaf coffee, etc). Had a cup of decaf green tea and water before I got home. Too diluted to tell??Been tracking my foods on fitday. I should be slightly pink.
