Ketosis is the native state of the body when you are born. By keeping carbohydrate intake limited, the liver will produce ketones and use this as the main fuel source. This is the same process our ancestors followed. Ketone bodies are made either from external sources (food) or internal sources (body fat). After a few weeks of adaptation, Mitochondria – which are considered the  cell’s energy generators – are ready to process this super fuel. Use of this fuel lowers the amount of free radicals in the body, increases ATP (energy) production, can improve cognitive functions, longevity and also lead to weight loss.
