Intense exercise — more than just fidgeting or pacing — uses ketones, when glucose is in short supply, which means the body has to create more ketones to replace what you use. This is great for those who are used to a moderate to intense activity level, but intensity is a fine dance between encouraging ketone production and elevating cortisol for the rest of us.
There is so much talk about the benefits of a ketogenic diet and its ability to improve fat burning, brain health, energy and anti-aging. The main units of energy on a ketogenic diet are ketone bodies, of which beta hydroxybutyrate (BHB) is the main player! This article will go over the health benefits of BHB and exogenous ketones. Additionally, this article will cover strategies on using exogenous ketones in your daily life.
Exogenous ketones drinks are growing in popularity as a method to elevate blood ketone concentrations and mimic a ketogenic diet without the need for dietary changes (Ari et al., 2016; Cox et al., 2016; Kesl et al., 2016; Caminhotto et al., 2017; Evans et al., 2017). The present study describes the pharmacokinetic and pharmacodynamics properties of ketone ester and salt drinks in humans at rest, and characterizes the effects of a prior meal, which is pertinent to use as a dietary supplement. The main findings were that KE drinks elevated blood d-βHB > 50% higher than KS drinks, the latter significantly increasing blood l-βHB, which was metabolized more slowly by the body. Both drinks had similar effects on FFA, TG, glucose and electrolyte concentrations, although with disparate effects on pH. A prior meal decreased total blood d-βHB appearance after a KE drink. Finally, either three KE drinks or nasogastric feeding effectively maintained nutritional ketosis over 1 mM for 9 h.

Im very excited about this product! I received it about a week ago and it helped me break my month+ plateau! I've been on a keto diet since mid-April and had lost 10 lbs but stalled out. Ill be honest, the after taste is not pleasant but I'll take it since it's working. I've lost 12.5 lbs and going strong. Feeling better than ever. Would recommend and buy again!
Exogenous ketones have a wide range of benefits that can enhance your fat-burning lifestyle. I personally use them daily as a strategy to heighten my mental performance and give my workouts an extra boost. For these purposes, I have also found it logical to combine exogenous ketones with other known health and performance boosting agents such as branched-chain amino acids and medicinal mushrooms.
For subjects completing the initial experiment (n = 15), the amount of d-βHB excreted in the urine increased with d-βHB intake, but was <1.5% of the total βHB ingested and was not different between matched doses of KE vs. KS (Figure (Figure1I).1I). There was no change in urine volume produced in different study conditions. Baseline urinary pH (5.7 ± 0.1) was unchanged by KE ingestion (pH 6.4 ± 0.2. p = 0.8 vs. baseline) but was significantly alkalinized by KS consumption (pH 8.5 ± 0.1. p < 0.001 vs. baseline) (Figure (Figure1J1J).
If you truly want to optimize health and performance, magnesium should not be neglected. There is still more research to be done on its potential. Good sources of magnesium include whole grains, nuts, seeds, legumes, green leafy vegetables, and supplements. However, be careful about taking too much magnesium at one time, or else you might end up running to the bathroom in a hurry.
After a minimal amount of internet "research," I decided to try my first exogenous ketones. I have used the ketogenic diet off and on for at 15 years and my body is pretty efficient at fat adapting. (Usually by the end of 2 strict days, I am in ketosis, but not without symptoms and intense cravings.) I can consistently fast from carbs for 20 - 24 hours and do this consistently. However, around hour 20, my mind begins to negotiate that intermittent fasting is advantageous too and that I can afford to have some carbs once a day. Hence the yo-yo effect.
In the second of these posts I discuss the Delta G implications of the body using ketones (specifically, beta-hydroxybutyrate, or BHB, and acetoacetate, or AcAc) for ATP generation, instead of glucose and free fatty acid (FFA). At the time I wrote that post I was particularly (read: personally) interested in the Delta G arbitrage. Stated simply, per unit of carbon, utilization of BHB offers more ATP for the same amount of oxygen consumption (as corollary, generation of the same amount of ATP requires less oxygen consumption, when compared to glucose or FFA).
