Were they indicating that this is bad breath? Typically the only breath side effects of Atkins is the expelling of Ketones in the breath, which actually gives off a slightly sweet smell. There are very odd cases where some people report urine that smells of nail polish remover (acetone) since acetone is a member or related to ketones (if I remember correctly) but this appears to be very rare.

Generally if they are indicating this as a bad side effect (the breath) I've found that most media is not friendly to low carb and will try to convince people it's bad through misinformation.

Apparently I had it yesterday. It was horrible...at my nieces basketball game & I did have any gum or mints...just kept drinking water but my daughter even commented on it though...lol. So wierd...guess I entered ketosis since I started livin low carb on Thursday. I went straight out & bought gum & mints. Maybe I need to get a portable toothbrush to keep in my purse too Does this last for a long time??

my husband and I have both had this.
