I am also taking a multivitamin and havent been using my ketostix for a couple weeks now. Ive only been on the atkins diet for like a month and a half so im pretty sure the stix havent gone bad. But before when i measured my ketones, the stix would show only trace when I wasnt drinking a lot of water. Now, i decided to measure for the fun of it recently and it was dark pink....moderate. Yesterday and today ive upped my water intake massively. So what does that mean......am i actually burning more fat because im drinking more water? The other thing is that yesterday I sorta did a fast....all i had was some cilantro, sugar-free jello and a small piece of fish all day. I was told to drink a lot of water if wanted to do that and only to do it for a day (i wanted to get past a small plateau). So what does that mean, anyone have any ideas?
