Ketosis is a metabolic state of the body, where fats are used to obtain energy due to the suppression of calories by carbohydrate restriction or in some other pathological metabolic conditions.

Ketones in your body

They are the molecules that are produced when the body metabolizes fat. During the breakdown of fats, ketone bodies are generated. These ketone bodies are further broken down into precursor molecules that are used as energy in substitution to glucose.

Ketone bodies are formed mainly in the liver. They occur when the supply of glucose sto the cells decrease persistently and liver and muscle glycogen stores are consumed.

Symptoms that you’re entering ketosis

Among the most notorious symptoms of ketosis are:

  • The feeling of thirst and dry mouth
  • Ketone breath
  • Sickness
  • Headache (headache)
  • Fatigue
