An efficient form of energy that improves human performance
Quite distinct from other macronutrients - proteins, carbohydrates
and fats - ketone bodies are an efficient form of energy that is
used rapidly by the body. Indeed, the brain can only make direct use
of two nutritional substances: ketones and glucose.
What are ketones?
When fasting or when on a ketogenic diet, our bodies produce
nutrients known as ketone bodies. In extreme conditions, such as
prolonged fasting or endurance exercise, the body's natural glycogen
stores
in the liver becomes exhausted. As a result, the body
releases fat, which burns instead of glucose. As this happens, level
of ketone bodies, as measured in the bloodstream, rise
significantly.
Ketones support metabolic efficiency
Ketones are a valuable energy source for the body that provide an
effective means of supporting metabolic efficiency.
