When someone does not eat enough carbohydrates the body metabolizes fats and proteins and produces ketones. When this is occurring, you are said to be in "ketoacidosis". It is not healthy if maintained for a prolonged period of time but OK for short intervals.
So my question to you is: Did eating more and overcoming ketoacidosis eliminate your Body Odor problem? And, what makes you think any of this has anything to do with candida?
