The article said: Researchers then administered D-βHb, a form of ketones, a byproduct released by the liver when the body burns fat instead of glucose for energy. They found that the synaptic activity that was previously impacted by acute insulin resistance was rescued, looking further, D-βHb seems to be an exogenous ketone: Exogenous ketones are a class of ketone bodies that are ingested using nutritional supplements or foods. ... Under physiological conditions, ketone concentrations can increase due to starvation, ketogenic diets, or prolonged exercise, leading to ketosis.[2] However, with the introduction of exogenous ketone supplements, it is possible to provide a user with an instant supply of ketones even if the body is not within a state of ketosis before ingestion.[1] However, drinking exogenous ketones will not trigger fat burning like a ketogenic diet. ... When exogenous ketone bodies are ingested, acute and nutritional exogenous ketosis is produced.[4][9] https://en.wikipedia.org/wiki/Exogenous_ketone https://en.wikipedia.org/wiki/Exogenous_ketone so, how do we supplement our diet?
