How do exogenous ketones fuel the brain?

Exogenous ketones serve as an alternative fuel source for the brain, especially beneficial when carbohydrate intake is low, making it a versatile option during states of ketosis or fasting. According to Louisa Nicola, exogenous ketones, like those found in products she uses and discusses, provide several cognitive benefits. These ketones enhance mental clarity, focus, and the accuracy of decision-making by offering an additional energy reservoir alongside glucose. Moreover, in hypothesized responses to cognitive demands, exogenous ketones appear to improve vigilance and reaction times. This metabolic flexibility facilitates a constant energy supply, avoiding the typical midday energy slump that many experience, thus supporting sustained cognitive performance 1.
