The culprit is often restaurant meals or other meals where the nutrition facts are not available with the food itself. Such “ignorance is bliss” situations allow us to avoid dealing with daunting numbers. Many people don’t hesitate to stop and enjoy a meal at a restaurant, but they freak out when they actually see the numbers on a label. By now, we all know that opting for fatty meat with a side of veggies cooked in butter isn’t that bad after all. It turns out that what you thought to be the safe, “healthy,” doctor-approved choice might not always be what you think it is.
In a subset of participants (n = 7) the effect of 3.2 mmol.kg−1 of βHB as KE and KS on blood pH and electrolytes after ketone drinks was investigated. Blood d-βHB kinetics were similar to those in the initial experiment (Figure (Figure3A).3A). After 60 min, blood pH declined from 7.41 to 7.31 following a KE drink (p < 0.001, Figure Figure3B).3B). Bicarbonate fell significantly from 23.6 ± 0.7 to 17.0 ± 0.8 mM following KE drinks (p < 0.001), but remained within the normal range (Figure 3C). Both ketone drinks significantly decreased blood potassium concentrations by 0.7 mM (both drinks p < 0.05, Figure 3D) and increased sodium and chloride concentrations (Sodium: both drinks p < 0.05, Chloride: KE = p < 0.05, KS = p < 0.005, Figures 3E,F).
Recent studies suggest that many of the benefits of the KD are due to the effects of ketone body metabolism. Interestingly, in studies on T2D patients, improved glycemic control, improved lipid markers, and retraction of insulin and other medications occurred before weight loss became significant. Both βHB and AcAc have been shown to decrease mitochondrial reactive oxygen species (ROS) production [36–39]. Veech et al. have summarized the potential therapeutic uses for ketone bodies [28, 40]. They have demonstrated that exogenous ketones favorably alter mitochondrial bioenergetics to reduce the mitochondrial NAD couple, oxidize the co-enzyme Q, and increase the ΔG’ (free enthalpy) of ATP hydrolysis . Ketone bodies have been shown to increase the hydraulic efficiency of the heart by 28 %, simultaneously decreasing oxygen consumption while increasing ATP production . Thus, elevated ketone bodies increase metabolic efficiency and as a consequence, reduce superoxide production and increase reduced glutathione . Sullivan et al. demonstrated that mice fed a KD for 10–12 days showed increased hippocampal uncoupling proteins, indicative of decreased mitochondrial-produced ROS . Bough et al. showed an increase of mitochondrial biogenesis in rats maintained on a KD for 4–6 weeks [44, 45]. Recently, Shimazu et al. reported that βHB is an exogenous and specific inhibitor of class I histone deacetylases (HDACs), which confers protection against oxidative stress . Ketone bodies have also been shown to suppress inflammation by decreasing the inflammatory markers TNF-a, IL-6, IL-8, MCP-1, E-selectin, I-CAM, and PAI-1 [8, 46, 47]. Therefore, it is thought that ketone bodies themselves confer many of the benefits associated with the KD.
The major determinant of whether the liver will produce ketone bodies is the amount of liver glycogen present (8). The primary role of liver glycogen is to maintain normal blood glucose levels. When dietary carbohydrates are removed from the diet and blood glucose falls, glucagon signals the liver to break down its glycogen stores to glucose which is released into the bloodstream. After approximately 12-16 hours, depending on activity, liver glycogen is almost completely depleted. At this time, ketogenesis increases rapidly. In fact, after liver glycogen is depleted, the availability of FFA will determine the rate of ketone production. (12)
The protocols carried out in these studies were approved by the the South West Frenchay NHS REC (15/SW/0244) (Study 1) and London Queen's Square REC (14/LO/0288) (Study 2 and 3). The studies were carried out in accordance with the recommendations of the Declaration of Helsinki, apart from pre-registration in a database. All subjects gave written informed consent in accordance with the Declaration of Helsinki.
I also chatted to some Prüvit reps, who told me that it might be necessary to keep taking the supplements for a couple of months to start to see more elevated ketones. Well, the proof is in the pudding (or in this case, in the fluorescent-coloured, artificial-tasting pink drink). But I would hesitate before spending money on a two-month supply just to find out if that’s true. Real Ketones’ Kegenix Prime was associated with a decrease blood ketones. Not a good start, and we’ll get back to this point later.
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.
Exogenous ketones are not a shortcut to nutritional ketosis, but they do give your body a break from full-time carb usage. They are a tool you can use to get into ketosis if your lifestyle makes it too difficult to do so without them. And they’re also a good way to get an increased edge for those who are very on top of their nutrition and performance.
In conclusion, drinks containing exogenous ketones, in either ester or salt form, can raise concentrations of blood βHB in humans, although elevation of l-βHB lasts longer after racemic KS consumption. Both KE and KS drinks mildly altered acid-base balance. Exogenous ketones lowered blood glucose and lipids without inhibiting endogenous insulin secretion. The KE delivered highly repeatable blood concentrations of d-βHB, although ketosis was decreased by a meal. Uptake and elimination of d-βHB were similar when several drinks were consumed in succession. The dietary KE could maintain ketosis using drinks taken regularly around a normal meal pattern, or using a continuous infusion via a nasogastric tube. Therefore, ketone drinks are a viable and practical alternative to dietary strategies to achieve ketosis.
Not everything is perfect with Ketōnd, so there are a few things you should know. One is that it is extremely powerful. The company is pretty adamant about taking the correct dosage - and they are right. This isn't your typical ketone supplement. I'd recommend starting off at half a scoop, even if you are used to taking a different ketone supplement. Odds are if you have your product was underdosed. So, it’s kind of a pain to remember all the time, but once you feel good with the half serving then you can work your way up to a full scoop. If you think it is too strong for you – just take one serving a day, not two, and you will be okay.
Getting into a state of ketosis normally involves eating a ketogenic diet consisting of around 80 percent fat, 15 percent protein, and 5 percent carbs. Over time, the body transitions from burning carbs for fuel to burning ketones—an alternative fuel source that the liver makes by breaking down fat, explains keto diet expert Amy Davis, RD, LDN. Since advocates say that ketosis can help you lose weight fast, think more clearly, and feel more energized, it’s tempting to try.
Ketoacidosis is driven by a lack of insulin in the body. Without insulin, blood sugar rises to high levels and stored fat streams from fat cells. This excess amount of fat metabolism results in the production of abnormal quantities of ketones. The combination of high blood sugar and high ketone levels can upset the normal acid/base balance in the blood and become dangerous. In order to reach a state of ketoacidosis, insulin levels must be so low that the regulation of blood sugar and fatty acid flow is impaired.
Neuroprotection: As humans age, the brain becomes more susceptible to neurodegeneration and subsequent conditions such as Alzheimer’s and Parkinson’s disease. Exogenous ketone supplementation appears to ameliorate the typical decline in cognitive function that comes with aging. The likely mechanism for this neuroprotective property is that ketone bodies reduce the inflammation and hyperexcitability that is normally exhibited as glucose metabolism declines in the brain.18, 19
Good question. There have been many tests and studies that have been conducted to see if ketogenic supplements genuinely do work and many of these studies have shown that ketosis theories are correct. Adding ketones to your body and using fats as a resource of energy has some fantastic effects and if done right can help your body fight all sorts of ailments such as cancer, heart disease, diabetes and many other illnesses that can only be cured by chemical therapy. Keto therapy or nutritional ketosis is paving the way for more natural solutions, and it's a good thing that scientists have created these exogenous ketone supplements that help us induce more ketones in our body.
At day 29 of the study, animals were euthanized and brain, lungs, liver, kidneys, spleen and heart were harvested and weighed. Organ weights were normalized to body weight. Ketone supplementation did not significantly change brain, lung, kidney, or heart weights compared to controls (Fig. 5a, b, d, f). MCT supplemented animals had significantly larger livers compared to their body weight (p < 0.05) (Fig. 5c). Ketone supplements BMS + MCT, MCT and BD caused a significant reduction in spleen size (BMS + MCT p < 0.05, MCT p < 0.001, BD p < 0.05) (Fig. 5e). Rats administered KE gained significantly less weight over the entire study compared to controls. BMS + MCT, BMS, and BD supplemented rats gained significantly less weight than controls during weeks 2 – 4, and MCT animals gained less weight than controls at weeks 3 – 4 (Fig. 6). Increased gastric motility (increased bowel evacuation and changes to fecal consistency) was visually observed in rats supplemented with 10 g/kg MCT, most notably at the 8 and 12-h time points. All animals remained in healthy weight range for their age even though the rate of weight gain changed with ketone supplementation [53–54]. Food intake was not measured in this study. However, there was not a significant change in basal blood glucose or basal blood ketone levels over the 4 week study in any of the rats supplemented with ketones (Fig. 7).
A small side effect for some people is “ketosis breath”. Many people on a ketogenic diet have experienced this temporary phenomenon, and those taking exogenous ketones can experience it as well. The smell of your breath when you are early in the ketogenic diet can have a hint of acetone to it, and it might be mildly unpleasant, but it’s also harmless. Most gum is pretty low in carbohydrates and is a great option while your keto breath fades.
Most supplements rely on BHB as the source of their exogenous ketone bodies. BHB is converted to acetoacetic acid with a small quantity converted to acetone through a acetoacetate decarboxylase waste pathway. Some of the acetoacetic acid will enter the energy pathway using beta-ketothialase, which converts acetoacetic acid to two Acetyl-CoA molecules (see diagram below2).
Despite the recent growth of the ketone salt market, there is very little published work analyzing the effects of these products on any biomarkers or performance measurements in humans. Several studies have been carried out in rats,6,7 with blood BHB levels being relatively low (<0.5 mM) post-consumption of salt drinks. In humans, ketone salts provided peak D-BHB levels of 1 mM, whereas the same amount of BHB in a ketone ester (BD-BHB) raised blood BHB to 2.8 mM.5
Most of the information regarding the effects of ketosis come from studies on the ketogenic diet, wherein ketones are made by the liver and become a major fuel source for the body. The ketogenic diet is currently under investigation for its potential therapeutic effects in a number of healthy and disease states. More recently, studies are beginning to reveal that many of the effects observed with the ketogenic diet are mechanistically attributable to ketones, which is a primary reason that exogenous ketones are being developed and studied. However, because they are such a new technology, there’s not a lot of data on exogenous ketones themselves. In a few pre-clinical studies, exogenous ketones have mimicked the therapeutic effects of the ketogenic diet”
As for MCT oil (and oil powders), powder formulations tend to cause less digestive distress (e.g. probiotics), but some folks object to the additional ingredients like sunflower lecithin or soluble corn fiber). Even if you’d like to eventually settle on an oil, I’d recommend starting with a powder to see how you respond and to give your body the chance to adapt over time.
Core BHB™ provides pure goBHB™ in an all-natural formula with no artificial sweeteners, making ideal for those on the keto diet, athletes, and people who are health-conscious. Even if you’re on a high-carb diet, Core BHB™ will rapidly elevate blood ketone levels and help your body enter a state of ketosis (often with 30 minutes of consumption). In turn, you will experience increases in energy, fat loss, endurance, and mental acuity. With regular use of Core BHB™, you can also speed up the transition from a higher-carb diet to the ketogenic diet and reduce symptoms of the “keto flu”.
I just started down the Keto path with the help (hopefully) of Ketond. My problem with all the websites and info I’ve seen is that no-one says how often you should take the EK. The packages say the serving size is one scoop…. but how many servings per day? It (Ketond) also says one serving will put you in Ketosis for 3-5 hours – so, does that mean you should take another serving after the 3-5 hours to stay in Ketosis?
This is another point that Brianna Stubbs put me onto: often, ketone-salt companies use terms such as “technology developed by Dominic D’Agostino” as a tool to market their products. Dom D’Agostino holds the patent for the technology being used but is not associated with the products and does not necessarily promote them. In many cases, this feels like a marketing strategy that name-drops a famous keto expert in order to make a product sound more legitimate. There is an example of this on Real Ketones’ website.
The main distraction which we have these days in our lives are the gadgets. Therefore, in order to fall asleep early, you need to make sure that you turn off your phones, tablets, computer, TV etc… at least 30 minutes before bedtime. This helps avoid insomnia as well as keep you away from the bright blue light which can interfere with your biorhythm.
The keto-esters are more appropriate for delivering higher doses of BOHB, but with repeated dosing can push the limits of taste and GI tolerance. There has been fairly extensive research on a compound 3-hydroxybutyl 3-hydroxybutyrate that is converted via hydrolysis and liver metabolism to yield 2 molecules of ketones, presumably mostly D-BOHB (Clarke 2012 and 2014). In a study involving lean athletes, an approximate 50 gram dose raised blood BOHB levels to 3 mM after 10 min and reached 6 mM by 20 min. Submaximal exercise resulted in increased ketone disposal from 2 to 3 hours and contributed significantly to whole body energy use during exercise (Cox 2016). This product has been shown to significantly reduce appetite after a single dose (Stubbs 2018) but its effect on body weight in humans over a longer period of time has not been studied, nor has its effect on blood glucose control been reported in humans with type 2 diabetes. However a single dose prior to a glucose tolerance test in healthy humans reduced blood glucose area-under-curve by 11% and non-esterified fatty acid area-under-curve by 44% (Myette-Cote 2018).
The CNS cannot use fat as an energy source; hence, it normally utilizes glucose. After 3–4 days without carbohydrate consumption the CNS is ‘forced' to find alternative energy sources, and as demonstrated by the classic experiments of Cahill and colleagues4 this alternative energy source is derived from the overproduction of acetyl coenzyme A (CoA). This condition seen in prolonged fasting, type 1 diabetes and high-fat/low-carbohydrate diets leads to the production of higher-than-normal levels of so-called ketone bodies (KBs), that is, acetoacetate, β-hydroxybutyric acid and acetone—a process called ketogenesis and which occurs principally in the mitochondrial matrix in the liver.6
Ketogenic Diets and Physical Performance – Impaired physical performance is a common but not obligate result of a low carbohydrate diet. Lessons from traditional Inuit culture indicate that time for adaptation, optimized sodium and potassium nutriture, and constraint of protein to 15–25 % of daily energy expenditure allow unimpaired endurance performance despite nutritional ketosis.
Individuals who have clinically unregulated blood sugar, such as those with diabetes, are cautioned to consult their trusted healthcare provider before choosing to use exogenous ketones. While it can be done safely, especially in the presence of a well-formulated ketogenic food plan, there may be a risk of blood sugar dropping unexpectedly low. There may be therapeutic value in this application, but close monitoring is key.
Great question. So if you are already in nutritional ketosis from your diet, exogenous ketones would still help raise ketone (energy) levels when you want that (maybe for focus at work or energy at the gym. They also help get you back into ketosis after cheat meals and skip the “keto flu” which is the period when your body is using up stored glycogen.
As KE drinks achieved a significantly higher d-βHB concentrations than KS, we investigated factors that may be important in the use of ketone drinks to achieve nutritional ketosis. Initially we determined the repeatability of blood ketosis following KE drinks and found little variation in kinetic parameters between individuals. Variability between participants was less than within the population, and accurate individual prediction of the d-βHB Cmax following a body-weight adjusted KE drink was achieved. Variability within individuals was likely due to normal daily changes in GI function, including gastric emptying, portal blood flow or intestinal transit time, which may alter KE hydrolysis and absorption.
Beta-Hydroxybutyrate (BHB) is a ketone body produced by the liver, from fat, for energy when glucose isn’t available. It ultimately becomes the body and brain’s primary source of energy. Since the liver naturally produces BHB during ketosis, the process can take quite some time, often resulting in symptoms of fatigue, hunger (cravings for sugar, a faster energy source), and mental cloudiness. That’s why supplementing BHB on a keto diet can have a profound positive impact.
