The production of testosterone and estrogen relies, in part, on fat intake, and both these hormones are critical to muscle gain, muscle retention, and nearly all performance adaptations. In addition, fat intake supplies essential fatty acids for the production of physiologically active lipid compounds that play key roles in the regulation of muscle growth and repair, particularly through their mediation of inflammatory processes.

Some have argued for fats as a primary fuel source for athletic performance, most recently for ultra-endurance performance. Proponents of this often argue that such performance benefits are not truly realized until an individual becomes “fat adapted” by staying away from carbohydrates almost entirely for weeks on end. As of this publication, there is very little evidence that fat is a high-performance fuel and a wealth of evidence that carbohydrates are the better performance fuel source. As important as fats are, they are not the best performance fuel, so recommendations for fat consumption ranges for sport are very similar to those for general health. CCH based on sport and recommendations for compliance on particular diet phases do alter these recommendations slightly, and these are discussed next.
