If the color is close to the original beige of the test strip, it means there are few if any ketones in your urine and you’ll need to make some dietary tweaks. This may include eating less fat. That’s because if you have doubled down on the healthy fats your body may be rebelling. One way to tell is if you are constipated. If you think this is the case, ratchet back the fats by 50% and see if it makes a difference.
Most of the ketone supplements out there are either underdosed or overpriced - some don't even bother to disclose how much BHB (ie ketones) is used in their product. And why would they? BHB is EXTREMELY expensive. So by not disclosing the amount the can get away with putting in as little as they want and still claim it's a ketone supplement while keeping their costs as low as possible.
Skipping breakfast on a keto diet is a popular way to boost ketone levels. Despite the age-old myth that breakfast is the most important meal of the day, research shows that breakfast skipping is not only safe but beneficial. Skipping breakfast causes intermittent ketosis and also suppresses appetite . Make sure your next meal of the day isn't too late in the evening as studies show that eating meals late at night causes weight gain and impairs fat metabolism .
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.
Another effect of the ketone drinks was to lower blood glucose, free fatty acids, and triglyceride levels. This sounds great. Elevated levels of all those markers are harbingers of disease, particularly if they remain chronically elevated. But think about what this means. If free fatty acids go down, that means adipose tissue isn’t being liberated for burning.
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.

A meal high in carbohydrate and calories significantly decreased peak d-βHB by ~ 1 mM (Figure (Figure4A)4A) and reduced the d-βHB AUC by 27% (p < 0.001, Figure Figure4B).4B). There were no significant changes in d-βHB Tmax (fed = 73 ± 6 min vs. fasted 66 ± 4 min). Despite the differences in d-βHB kinetics after the meal, there were no effects of food on urinary ketone excretion (Figure (Figure4C),4C), plasma AcAc (Figure (Figure4D)4D) or breath acetone (Figure (Figure4E)4E) following KE ingestion. Plasma AcAc kinetics followed a similar time course to d-βHB, with the ratio of blood d-βHB: AcAc being 6:1 when KE drinks were consumed whilst fasted, and 4:1 following the meal. As observed in Study 1, breath acetone concentrations rose more slowly than blood ketone concentrations, reaching a plateau at 150 min and remaining elevated for at least 4 h (Figure (Figure4E4E).
The same question posed in a different way can be, what’s better, getting protein from powder or from a grass-fed steak or wild salmon? Omega-3 from supplements or from a variety of healthy wild fish? Just like with health supplements where you consume an isolated nutrient instead of the whole food where it comes from, if it’s possible to get what you need from whole food or nutrition, then that’s probably the best choice.
Blood d-βHB concentrations rapidly increased to a maximum of 2.8 ± 0.2 mM following the KE drink and to 1.0 ± 0.1 mM following the KS drink (Figure (Figure1A).1A). After the peak was reached, blood d-βHB disappearance was non-linear, and followed first order elimination kinetics as reported previously (Clarke et al., 2012b; Shivva et al., 2016). d-βHB Tmax was ~2-fold longer following KS drinks vs. KE drinks (p < 0.01, Figure Figure1B),1B), and KS d-βHB AUC was ~30–60% lower than the KE drink (p < 0.01, Figure Figure1C1C).
Let’s take a look at some of the facts and misconceptions about three of the minerals used to make ketone mineral salts: sodium, calcium, and magnesium. Potassium is very hygroscopic, meaning that it absorbs water very easily. Therefore, it is only feasible that it can be utilized in liquid formulations. Thus, one should be cautious if companies say they have potassium BHB salt powder in their product. I’d be very surprised if that’s actually the case.
“Though the small amount of carbohydrates in the diets may be more than balanced by the potential sugar production from the large amount of protein to keep the ratio of fatty acid to glucose below the generally accepted level of ketogenesis, the respiratory quotient data suggest another mechanism also” ß (most likely the CPT-1A mutation, which had not been discovered at that time)
Those new to keto should be testing to see if their bodies are in ketosis, regardless of method. Testing, in general, is the most objective way to know if you’re in ketosis. There can be some subjective benefits of ketosis: appetite suppression, fat loss, low blood sugar, improvement in mental cognition and focus. But before recognizing these subjective benefits, it’s important to track and measure the level of ketones in the blood to ensure ketosis on a physical level.
The difference in peak blood d-βHB concentrations between matched amounts of βHB as ester or salts arose because the salt contained l-βHB, as the blood concentrations of d- plus l-βHB isoforms were similar for both compounds. It is unclear if kinetic parameters of KE and KS drinks would be similar if matched d-βHB were taken in the drinks. Unlike d-βHB, blood l-βHB remained elevated for at least 8 h following the drink, suggesting an overall lower rate of metabolism of l-βHB as urinary elimination of l-βHB was in proportion to plasma concentration. Despite similar concentrations of total βHB, breath acetone was ~50% lower following KS drinks compared to KE, suggesting fundamental differences in the metabolic fates of D- and L-βHB. These findings support both previous hypotheses (Veech and King, 2016) and experimental work in rats (Webber and Edmond, 1977), which suggested that the l-isoform was less readily oxidized than the d-isoform, and is processed via different pathways, perhaps in different cellular compartments. It seems that l-βHB is not a major oxidative fuel at rest, and may accumulate with repeated KS drinks. However, the putative signaling role of l-βHB in humans remains unclear. In rodent cardiomyocytes, l-βHB acts as a signal that modulates the metabolism of d-βHB and glucose, Tsai et al. (2006) although no differences in blood glucose were seen here. Furthermore, L-βHB can act as a cellular antioxidant, although to a lesser extent than D-βHB (Haces et al., 2008).
When you are in a state of ketosis, the body turns fatty acids into ketones - these appear as beta-hydroxybutyrate in the blood. Measuring blood ketones is regarded as the gold standard and most accurate way to track ketone levels. Testing this way can be expensive, its can cost up to $3 a strip, so if you're testing multiple times a day it can get pricey.
Personally, I think it is wise to include a regular carb meal in your diet if you are going to follow a ketogenic diet. Long term ketogenic diets do seem to downregulate your thyroid and metabolism, and a weekly carb meal (or carb day) can help avoid this. The Carb Nite diet by J. Kiefer is a good example of this. And BJJCaveman posted his labs showing how a weekly carb meal helped his thyroid HERE.
As I mentioned before, this was by no means a scientific experiment carried out under lab conditions, and this means we can only draw tentative conclusions from any of the data. Nonetheless, carrying out the testing in the way described above should give most people a good idea of how well the ketone supplements show the noticeable benefits they are marketed to have and provide a clear enough basis for a decision on whether or not to buy them.
We will go deep in the science behind this fascinating diet and then review some of the best exogenous ketone supplements out there in the market. Because without the knowledge and the right information about exogenous ketones that you can properly follow, you might never reach your goals and you may as well keep eating that mashed potato for dinner and club sandwich for lunch.
Think about it like building muscle, good supplements can enhance your results, but if you don't eat right and exercise, supplements are just useless. You can't just sit on the couch to watch TV, eat potato chips all day and drink some supplements and expect to gain muscle. A supplement is not a miracle. It's just an addition and before you add it to your diet, you need to get the basics right first, which is dieting and exercise in the case of building muscles. The supplements are not going to lift the heavy weights for you. You do!
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!
Personally, I do this on Friday night to Saturday night, so if something happens and my hunger hasn’t crashed by Sunday morning, I have another day that I can go zero carb to keep the momentum going. While the body will trigger ketosis as soon as you run out of glycogen, hunger is attached to your triglyceride and insulin levels, which might take an extra day to normalize.
For example, the popular Raspberry Ketones supplement is far different than what we have been discussing in this article. Raspberry ketones are unrelated to the ketones that are produced in the body and are not the same as the ketone salts that have been covered above. There are some limited studies that indicate raspberry ketones may be helpful for weight loss, but they are inconsistent. Raspberry ketones are the molecules that give raspberries their scent and flavor, and in some cases, aren’t even derived from raspberries at all.
This was a big surprise. We were at the very least expecting that drinking a ketone supplement would cause blood ketones to rise, but an average increase of 0.33 mmol/L is very small. The supplement associated with the highest average increase in blood ketones was Prüvit’s Keto-OS Max, but it was only an increase of 0.6 mmol/L. Brianna Stubbs, the ketone researcher I consulted with, agrees that an increase of below 2.0-3.0 mmol/L is unlikely to be of much use.
Effects of ketone supplementation on organ weight: Data is represented as a percentage of organ weight to body weight. a, b, d, f Ketone supplements did not significantly affect the weight of the brain, lungs, kidneys or heart. c Liver weight was significantly increased as compared to body weight in response to administered MCT ketone supplement compared to control at the end of the study (day 29) (p < 0.001). e Rats supplemented with BMS + MCT, MCT, and BD had significantly smaller spleen percentage as compared to controls (p < 0.05, p < 0.001, p < 0.05). Two-Way ANOVA with Tukey’s post-hoc test; results considered significant if p < 0.05. Error bars represent mean (SD)
Too much cortisol tells the liver that you are in physical danger and need a lot of energy fast. The brain doesn’t understand the difference between physical danger and emotional stress. When emotionally stressed, the brain thinks you’re in a life-and-death situation, so the liver comes to your rescue and gives you the glucose you need to fight off your attacker.
MCT oil has recently been used to induce nutritional ketosis although it produces dose-dependent gastrointestinal (GI) side effects in humans that limit the potential for its use to significantly elevate ketones (>0.5 mM). Despite these limitations, Azzam and colleagues published a case report in which a 43-year-old-man had a significant decrease in seizure frequency after supplementing his diet with 4 tablespoons of MCT oil twice daily . An attempt to increase his dosage to 5 tablespoons twice daily was halted by severe GI intolerance. Henderson et al. observed that 20 % of patients reported GI side effects with a 20 g dose of ketogenic agent AC-1202 in a double blind trial in mild to moderate Alzheimer’s patients . We visually observed similar gastrointestinal side effects (loose stools) in the rats treated with MCT oil in our study. Rats were closely monitored to avoid dehydration, and gastric motility returned to normal between 12–24 h. Interestingly, the BMS + MCT supplement elevated βHB similarly to MCT oil alone, without causing the adverse gastrointestinal effects seen in MCT-supplemented rats. However, this could be due to the fact in a 10 g/kg dose of BMS + MCT, only 5 g/kg is MCT alone, which is less than the 10 g/kg dose that elicits the GI side effects. This suggests that this novel combination may provide a more useful therapeutic option than MCT oil alone, which is limited in its ability to elevate ketones in humans.
Baseline measurements showed no significant changes in triglycerides or the lipoproteins (data not shown). Data represent triglyceride and lipoprotein concentrations measured after 4 weeks of daily exogenous ketone supplementation. No significant change in total cholesterol was observed at 4 weeks for any of the ketone treatment groups compared to control. (Fig. 1a). No significant difference was detected in triglycerides for any ketone supplement compared to control (Fig. 1b). MCT supplemented animals had a significant reduction in HDL blood levels compared to control (p < 0.001) (Fig. 1c). LDL levels in ketone-supplemented animals did not significantly differ from controls (Fig. 1d).
In addition to the Weir coefficients being potentially off (which impacts EE), the RQ interpretation may be incorrect in the presence of endogenous or exogenous ketones. As a result, the estimation of fat and glucose oxidation may be off (though it’s directionally correct). That said, the current interpretation seems quite plausible—greater fat oxidation when I had to make my ketones; less when I got my ketones for “free.”
