Ketosis
Ketosis is defined as fat-burning metabolism that results in the production of ketones (acids) in the body.

Ketones act as a cellular fuel much like glucose, but through different metabolic pathways than glucose metabolism.

Ketones are routinely produced in diabetics due to insufficient glucose cellular metabolism, and increasingly elevated levels of ketones indicate an uncontrolled diabetic condition.

High levels of ketones can be dangerous, and result in a condition called diabetic ketoacidosis (DKA).

In non-diabetics, ketosis is commonly associated with weight loss and fitness programs, but also has medical benefits in Alzheimer's Disease and high risk cardiac patients.
