Sounds like ketosis to me. Two weeks is bit long to get there though...

Probably ketosis. A good sign that you are fat burning. For me it is a sickly sweet taste. For others metallic. I have found drinking more water and brushing my teeth more often makes it more palatable! It could be aftertaste from a certain food but I really think it is ketosis breath! Congrats!!!!..

Ya, it's kind of metalic, now that you mention it. Sheesh, figures it would take me 2 weeks to get in ketosis...

The good part is now you should start releasing pounds faster...

I'm certain i'm in ketosis, but I don't ever get a weird taste in my mouth. I think maybe for some people it comes and goes...
