Fueling Performance: Ketones Enter the Mix

Cell Metab. 2016 Sep 13;24(3):373-375. doi: 10.1016/j.cmet.2016.08.021.


Ketone body metabolites serve as alternative energy substrates during prolonged fasting, calorie restriction, or reduced carbohydrate (CHO) availability. Using a ketone ester supplement, Cox et al. (2016) demonstrate that acute nutritional ketosis alters substrate utilization patterns during exercise, reduces lactate production, and improves time-trial performance in elite cyclists.
