Ketosis is a natural reaction of the body when deprived of carbohydrates (sugar). When the body no longer has enough sugar to provide the energy it needs, it uses its fat, which is stored energy.
With a ketogenic diet, the liver comes into play and transforms fat into 3 ketone bodies: acetylacetate, beta-hydroxybutyrate and acetone. These ketones will replace sugar as an energy source and will have beneficial effects on the human body including a reduction in hunger, a feeling of physical and mental well-being and a powerful anti-inflammatory effect.
Usually, this adaptation will only take a few days. Some researchers call these ketones a natural medicine. The good news is that it can be easily measured by urinating a “ketone test strip”. The presence of ketones means that your body has naturally adapted to the carbohydrate deficiency and that you are losing fat quickly. This natural mechanism of adaptation to carbohydrate and calorie deprivation has allowed the caveman to pass through the centuries to the present day.
