Yep, sounds as though you are in ketosis.
The ketone bodies are excreted via our urine, lungs and skin (sweat).

The best way to dilute the whole shebang, and therefore the odour, is to drink plenty of water.

The other suggestion is to perhaps increase your level of healthy carbs. I'm not sure what you are eating, but as you are doing very well indeed, you may well find you can eat more carbs, still lose and, er, smell a touch better!

Well done on your weight loss so far, Ginger!
