Whether following a keto plan or consuming a more traditional bodybuilding diet, exogenous ketones teach the body to adapt to using ketones for fuel. As a result, the body learns to better utilize stored body fat to further enhance the production and utilization of (and thus more efficiently raise and sustain) ketones for energy purposes. By inducing nutritional ketosis without dietary restrictions, exogenous ketones can be used by both ketogenic and non-ketogenic dieters to enhance keto-adaptation, boost fat loss, improve health and maximize athletic performance.
It's been shown that exogenous ketones, most notably BHB, can also reduce the need for a large amount of branched-chain amino acids (BCAAs) as fuel (deamination), ensuring that more anabolic aminos are available for protein synthesis (the building of new muscle tissue). The breakdown of muscle glycogen for fuel can also be suppressed when supplementing with BHB. This carb-sparing effect helps reduce the accumulation of lactate (a metabolic byproduct of anaerobic activity which reduces training output), which enhances training endurance and intensity. Training with great intensity normally requires a switch to carbohydrates upon the cessation of fat oxidation. An effective energy alternative to carbs, ketones have been shown to minimize this effect, leaving more stored carbs for greater training efforts.
