I heard of ketosis with the high protein diet, but never with fasting. Can someone explain if this happens to us when we fast?

In a nutshell: The bulk of the stored energy in the body is in the form of fat. The bulk of the fat is triglycerides (saturated). When triglycerides are catabolised (broken down) to supply energy, typically four different molecules emerge: Glycerol and 3 \"ketone bodies\" or ketones. 2 Glycerols combine to form Glucose (blood sugar) whilst the ketones are catabolised further without any recombinations.

Thus, whenever you \"burn fat\" you form ketones, become ketotic.

In the case of the ill advised high protein diet, the ketosis is forced on the body, meaning you form more ketones than you need, and they pass out through the urine, lungs and skin. Thus the ketosis is easily observed.

In the case of the natural process of fasting, you form as many ketones as your cells need for energy, so often it does indeed go unnoticed. Not being observed, however, does not mean not existing. In practically all cases we find at least some ketones in the urine. A simple urine dipstick test should confirm it.
