What Is the Keto Diet and Does It Work?

All else being equal, the rate of gluconeogenesis (GNG) in the body is constant. It happens all the time, for all people, even type 2 diabetics. It has no correlation whatsoever to protein intake, because the body will break down body tissues if there is not enough protein from other sources.

Therefore, if this article were correct, then NO ONE would be in ketosis.

But in fact, everyone who is in ketosis is also undergoing GNG. In fact, they are undergoing it at a faster rate, and yet, they remain in ketosis. GNG is providing just enough glucose for the handful of body tissues that cannot utilize ketones, and preventing the body from going hypoglycemic. Yet the bulk of the body, metabolically speaking, is using ketones.

And besides the clear scientific reasons stated above, you have the millions of people who do keto, and regularly test their urine to know that they are in ketosis. QED.

Ketosis is not that hard to get into.
