The process of ketosis is one of the physiological effects of fasting in which the brain (and some other bodily processes) uses ketones produced from fatty tissues as a fuel instead of the usual glucose. This is called muscle sparing.
The body only has the capacity to store about 300 to 400 grams of carbs, so if you've been following Atkins Induction correctly or Protein Power (20 to 30 net carbs per day), after 5 days you'll definitely be in Ketosis even if it's not showing up on the Ketone sticks.
