Abstract
The efficiency in which the body utilises oxygen to produce energy during exercise (known as exercise economy), is one of the key physiological determinants of endurance exercise performance (1). Key enablers of energy production during endurance exercise include oxygen delivery to the mitochondria and the availability of a substrate (usually carbohydrate or fat) in the muscle (2). Endogenous carbohydrate (CHO) stores are finite, and depletion of CHO stores is a limiting factor to endurance performance. Strategies that improve fat utilisation have been proposed as an alternative approach to fuelling prolonged exercise since body fat stores represent a relatively ‘unlimited’ energy supply (3). One suggestion to improve fat utilisation is the muscle retooling that occurs with adaptation to a low-carbohydrate, high-fat (LCHF) diet. Indeed, exposure to a LCHF diet can achieve a substantial (~200%) increase in exercise fat oxidation, even in well-trained athletes (4,5). However, this is associated with an impairment of endurance performance particularly at higher exercise intensities (5,6). This impairment has been attributed to the higher oxygen cost of adenosine triphosphate (ATP) resynthesis from fat oxidation compared to CHO oxidation (5), which reduces exercise economy and effectively limits the production of ATP from the given oxygen supply.
