Question: What is Ketosis? Answer: A lot of people are confused by the term "ketosis." You may read that it is a "dangerous state" for the body, and it does sound abnormal to be "in ketosis." But ketosis merely means that our bodies are using fat for energy. Ketones (also called ketone
bodies) are molecules generated during fat metabolism, whether from the
fat in the guacamole you just ate or fat you were carrying around your
middle. When our bodies are breaking down fat for energy, most of the it
gets converted more or less directly to ATP. (Remember high school
biology? This is the "energy molecule.") But ketones are also produced as part of the process.
When people eat less carbohydrate, their bodies turn to fat for energy, so it makes sense that more ketones are generated. Some of those ketones (acetoacetate and ß-hydroxybutyrate) are used for energy; the heart muscle and kidneys, for example, prefer ketones to glucose. Most cells, including the brain cells, are able to use ketones for at least part of their energy. But there is one type of ketone
molecule, called acetone, that cannot be used and is excreted as waste,
mostly in the urine and breath (sometimes causing a distinct breath
If enough acetone is in our urine, it can be detected using a dipstick commonly called by the brand name Ketostix (though there are other brands, as well). Even though everyone is generating ketones continuously, this detection in the urine is what is commonly called "ketosis."The higher the concentration of ketones in the urine, the more purple the sticks will turn. The Atkins Diet, in particular, advises people to monitor ketosis as an indication of fat burning. Other reduced carbohydrate diets don't pay much attention to this, or aren't low enough in carbs to make much of an impression on the sticks. (The latter type of diet is sometimes called a "nonketogenic" low-carb diet.)
Why do some people think ketosis is a bad thing?
There is an assumption that if a body is burning a lot of fat for
energy, it must not be getting "enough" glucose. However, there is no
indication, from studying people on reduced carbohydrate diets, that
this is the case (though there is usually a short period of adjustment
-- less than a week, in most cases). Although it's true that our bodies
can't break fat down into glucose (though, interestingly, they easily
use glucose to make fat), our bodies can convert some of the protein we
eat into glucose. Indeed, this works well for people who don't tolerate a
lot of sugar, because this conversion happens slowly so it doesn't
spike blood glucose.A dangerous condition called ketoacidosis can develop in those with type 1 diabetes, and it is sometimes confused with normal ketosis.
The body usually avoids this state by producing insulin, but people
with type 1 diabetes are unable to produce insulin. Even most people
with type 2 diabetes who inject insulin usually produce enough insulin
of their own to prevent ketoacidosis.
