First answer was correct - Ketosis.
When your body is burning fat instead of sugar for energy a change happens in your body because broken down fat is not the easiest fuel to use. That change leads to some smelly side effects in some people - bad breath, a fruity smell, body odor changes.
Take the bad breath as a sign that you are doing what you need to do. Get some listerine or other sugar free breath strips, get a new deodorant if you need to as well, and keep on trucking.
