Not to be gross.. I do brush, floss and use mouth wash. My mother said I never had this before.....

Has anyone had this or heard of it?

High Protein levels in the body cause the body to go into ketosis which is just fat burning. I do believe it causes bad breath so that could be the problem I don't know for sure though just a thought you could look into it.

Going on a low carb diet like Atkins causes bad breath because of ketosis. If you are only doing protein shakes this could be the reason.

Early in my WLS venture, I did notice a body odor coming off of me. My husband never said anything, but I could tell. I thought it was odd, because I wasn't eating anything. It's probably due to what is mentioned above; ketosis. I don't remember bad breath specifically, but I did notice a change. It only lasted a short while, and I'm back to my beautiful smelling self

I have a sour taste in my mouth after drinking protein shakes. But I don't know why. When I go for my two week follow up, I will ask the doc.

Thank you everyone! I feel better. I will also ask Dr too.
