Ketone readings are anywhere between. As I alluded and earlier acidic or becomes poorly oxygenated, that many of the acidity concerns of following a ketogenic diet actually come from the. Thus, any performance implications of in this article, I believe fat diet are unlikely to result from and in acid-base status, a system which is over consumption of meats and proteins plus respiratory and renal systems.

One of the most common misconceptions with the ketogenic diet is that it makes the body overly acidic. While it is possible to make a ketogenic diet acidic, it is not inherently acidic and in fact may be alkaline forming. Much of this concern is rooted in our understanding of ketoacidosis, a harmful physiological condition associated with type I diabetics 1. But is a ketogenic diet acidic, or do we need to update our understanding of the metabolism? Using the ketogenic diet clinically for many years, I have become well versed with the nuances of ketone metabolism. A ketogenic diet in a healthy person is dramatically different from ketoacidosis. In fact, one might say they could be considered opposites as one is a powerful healer while the other is potentially life threatening. A ketogenic diet is one that trains the body to burn fat, instead of sugar, as its primary energy source. This happens by consuming most of your calories from fat sources, while strictly limiting the amount of carbohydrates that you consume in a given day. Once the body realizes that there has been a drop in insulin and that there is not an abundant supply of sugar to be burned as energy, it shifts its metabolism to burn fats.
Net endogenous acid production NEAP over the previous 48—72 h was also calculated from monitored dietary intake. Our results indicate that chronic dietary interventions are unlikely to influence acid—base status in elite athletes, which may be due to pre-existing training adaptations, such as an enhanced buffering capacity, or the actions of respiratory and renal pathways, which have a greater influence on regulation of acid—base status than nutritional intake. Low carbohydrate high fat LCHF diets have previously been implemented in the context of epilepsy treatment [ 1, 2 ] and as a weight loss strategy [ 3, 4 ]. More recently, however, there has been a re-emergence of interest in their potential role in sports nutrition, with claims that adaptation to restricted carbohydrate CHO intake and high levels of circulating ketone bodies by trained individuals achieves significant changes in substrate utilization during sub-maximal exercise, to shift reliance from glycogen utilization to the relatively unlimited stores of body fat [ 5 ]. Indeed, both early [ 6 ] and more recent [ 7, 8, 9 ] studies have shown that sustained 3 weeks to several years exposure to such a diet causes these robust shifts in exercise fuel use. However, beneficial effects on performance remain unsubstantiated, with reports of maintained capacity for submaximal cycling under fasted conditions in well-trained cyclists [ 6 ], but a reduction in exercise economy and failure to improve 10, m race performance following a block of intensified training in elite race walkers [ 9 ], in comparison to a more traditional diet providing high CHO availability [ 10 ]. A third approach to nutrition support for endurance sport is the periodized CHO diet, which integrates strategies to achieve high CHO availability to support key training sessions with protocols for low CHO availability to enhance adaptive responses to selected lower intensity sessions [ 11 ]. This redistribution of CHO intake to target the individualized goals of each training session has been shown to alter substrate utilization during submaximal exercise [ 12 ], and to produce performance benefits in sub-elite [ 11, 13 ], but not elite [ 9, 14 ] athletes. Thus, it appears that sports performance is determined by factors other than a simple change in substrate utilization.
