This site complies with the HONcode standard for trustworthy health information: verify here. Following my recent post about carbohydrates, I've put together what I consider to be the most important facts about ketosis and measuring ketone bodies.
Ketosis is a state at which your body produces ketones in the liver, shifting the body's metabolism away from glucose and towards fat utilisation. While nutritional ketosis is perfectly safe, ketoacidosis is an indicator of serious health problems. There are three types of ketone bodies: Acetone, Acetoacetate and Beta-Hydroxybutryate (BHB). It's the most accurate way to measure ketone bodies, beta-bydroxybutryate (BHB, although not technically a ketone body). According to Volek and Phinney in The Art and Science of Low-Carbohydrate Living (chapter 13, Ketones - To Measure or Not), a non-invasive and cheap alternative is to measure breath acetone concentration. The Ketonix Acetone Breathalyzer is available and offers an easy and inexpensive way to test your breath ketones (acetone).
Ketostix, Uriscan and other urine detection strips are not as accurate and may not work for some people.
Some people use them to test if they are sensitive to certain foods that may be keto-friendly but still have a negative effect on their weight loss. As mentioned above, although your body may produce ketone bodies which you can measure in your blood stream, Ketostix only show excess ketone bodies excreted via urine. Most people believe that in order to lose as much fat as possible, they need to restrict their carbs intake as much as they can.
Also, when becoming keto-adapted, some individuals tolerate relatively greater carbohydrate intakes without disrupting ketosis.
If you want to know more about ketone levels and their effect on fat loss, have a look at this post: Do Ketones Matter? I've been in nutritional ketosis on and off for almost two years and can't really complain about urine strips. To easily increase your fat intake on a ketogenic diet, try fat bombs - snacks with at least 80% fat content. Ketone levels tend to be higher after extensive aerobic exercise as your body depletes glycogen stores.
Finally, if you find it hard to lose weight on a ketogenic diet, there may be plenty other reasons than the level of ketone bodies: Not Losing Weight on Low-Carb Ketogenic Diet? Please note that due to the high volume it can take us several days before we can approve and reply to your comment. Those are amazing results Angela, well done!I I wouldn't trust the numbers on Ketostix - I would only use them to see how my body reacts to foods and whether I am in Ketosis, and only for the first few weeks.
Can you tell me what range in the Ketonix is equivalent to (0.5 to 3.0 mM) as measured in the blood test? Hi I have been on the low carb diet for about two months now, I am 214lbs and have only lost 11lbs since being on the diet. Treatment of high blood pressure in chronic kidney disease should include specification of target blood pressure levels, nonpharmacologic therapy, and specific antihypertensive agents for the prevention of progression of kidney disease (Guideline 13) and development of cardiovascular disease (Guideline 15). In 1998, the NKF published the Report of the Task Force on Cardiovascular Disease in Chronic Renal Disease.9 One of the major goals of the Task Force was to assess current knowledge about the association of high blood pressure and cardiovascular disease in chronic kidney disease. In July of 2001, the NKF initiated a KDOQI Work Group specifically to conduct a detailed review of evidence and to develop clinical practice guidelines for the management of blood pressure in chronic kidney disease to prevent progression of kidney disease and development and progression of cardiovascular disease in chronic kidney disease.
It is likely that excess risk in patients with low blood pressure reflects confounding effects of underlying or pre-existing cardiovascular disease on mortality, while the true relationship of blood pressure to mortality is reflected in the excess risk in patients with very high blood pressure as in the general population. Overall, these studies demonstrate that high blood pressure is associated with faster progression of chronic kidney disease, development of cardiovascular disease, and, likely, higher mortality in patients with chronic kidney disease.
Figure 22 shows the prevalence of high blood pressure by level of GFR among 15,600 patients participating in the NHANES III. High blood pressure is not optimally controlled in patients with chronic kidney disease (S).
An estimated 3% (5.6 million) of the US population had elevated serum creatinine according to this definition, and of these 70% had high blood pressure. Prevalence of elevated serum creatinine by JNC-VI blood pressure category and self-reported treatment with anti-hypertensive medications (NHANES III).
Estimated number of individuals with elevated serum creatinine by JNC-VI blood pressure category and self-reported treatment with anti-hypertensive medications (NHANES III). Figures 23 and 24 show the prevalence and number of individuals with elevated serum creatinine among patients receiving and not receiving antihypertensive therapy, according to blood pressure category.
Treatment of high blood pressure in chronic kidney disease should include specification of target blood pressure levels, nonpharmacologic therapy, and specific antihypertensive agents for the prevention of progression of kidney disease (Guideline 13) and development of cardiovascular disease in patients with chronic kidney disease (Guideline 15) (R). Unlike other guidelines in Part 6, this guideline is not based on a systematic review of the literature. A major limitation of cross-sectional studies has been the absence of a clear definition of chronic kidney disease. Detection, evaluation and management of high blood pressure should be the goal for all health care providers for patients with chronic kidney disease. The high prevalence of earlier stages of chronic kidney disease requires a coordinated national effort by governmental agencies and nongovernmental organizations to address these issues. A broad set of recommendations for research on high blood pressure in chronic kidney disease was developed by the NKF Task Force on Cardiovascular Disease in Chronic Renal Disease.248 Recommendations for observational studies are reproduced in Table 74 and for clinical trials in Table 75.
Urine test strips Home kit (urine dip sticks) will analyze and check your urine for 10 different parameters - from glucose, ketones to leucocytes , pH, specific gravity etc. Many medical conditions can be investigated and detected by using medical urine test strips, and they are a great help to ascertain your health status.
Our strips are available for home use, and test simultaneously for the presence of glucose, ketones, blood, protein, nitrite, pH, urobilinogen, bilirubin, leucocytes in urine as well as specific gravity. We believe that the combination of reagents that are tested gives a good general coverage for a range of health indicators. False positive results may occur with highly pigmented urine specimens or those containing large amounts of levodopa metabolites. Acetone or beta-hydroxybutyric acid have no significant effect on this test.For more information on ketones in your urine please click here. This test is based on the pseudoperoxidase activity of hemoglobin which catalyzes the reaction of 3,3'5,5'-tetramethylbenzidine and buffered organic peroxide, 2,5-dimethylhexane-2,5-dihydroperoxide. This test is slightly more sensitive to free hemoglobin and myoglobin than to intact erythrocytes. This test is based on the reaction of p-arsanilic acid and nitrite in urine to form a diazonium compound. This test is based on double indicators (methyl red and bromothymol blue), which give a broad range of colors covering the entire urinary pH range.
Certain drugs, such as those used for hypertension and heart diseases (acetazolamides) may cause an alkaline urine. The test is based on a diazotisation reaction of 4- Methoxybenzene diazoniurn salt and urinary urobilinogen in a strong acid medium. This test is based on the coupling of bilirubin with 2.4-dichlorobenzene diazonium salt in a strong acid medium. Since the bilirubin in samples is sensitive to light, exposure of the urine samples to light for a long period of time may result in a false negative test result.


This test is based on the pka change of certain pretreated polyelectrolytes in relation to the ionic concentration.
As you can see - the test strips will test the entire spectrum of what can be tested by using urine dipstick test strips. Instead of just testing for ketones or glucose, you can now test the entire spectrum of your urine, by using our very affordable urine test strips.
The presence of ketones in your body, which is indicative of lipolysis, is a definite proof of ketosis.
Ketosis is not only a great weight loss tool, but it has been used for treating diseases such as epilepsy, Alzheimer's or cancer. Ketoacidosis occurs in serious health conditions such as type 1 and type 2 diabetics and alcoholics and has nothing to do with nutritional ketosis. Blood ketone meters can precisely determine the level of ketones in your blood but they are also pricey. Keep in mind that breath ketones do not always exactly correlate with blood ketones and are affected by several factors (alcohol consumption and water intake). They only show excess ketone bodies excreted via urine (acetoacetate) but tell you nothing about the level of ketones in your bloodstream (BHB) which is most probably higher. Although there are 3 types of ketones (acetone, acetoacetate and beta-hydroxybutyrate), they only measure acetoacetate.
Some diet authors, including Atkins himself, supported the idea that more ketones equals more weight loss. While urinary ketone excretion means that body fat is being excreted causing fat loss, the effect is minimal: Based on recent studies, the number of calories lost in the urine as ketones is not significant (100 kcal at most).
Individuals who maintain lower ketone levels (trace ketones) appear to lose fat more efficiently.
Although urine detection strips may not be accurate for keto-adapted people, they work for most of those that have just started the ketogenic diet.
If you need to keep track of your ketone levels, use a blood ketone meter or the breathalyser. To avoid this, drink a lot of water, mint tea and make sure you eat foods rich in electrolytes.
To find out more about the ketogenic diet and keto-friendly recipes, check out my apps KetoDiet, KetoDiet Basic and my new cookbook! I slipped into ketosis by lowering my carbs to my comfort zone and increasing animal fats, also to my comfort zone, so at first I did not know I was in ketosis until the signs appeared: headache and cramps, which I took care of right away (salt and water) and have been in ketosis now for 3 weeks very comfortably. Two years ago, right before taking a new job in Arizona, several suspicious spots were detected in my liver and kidneys, and one in my lower left lung.
It depends when you measure your ketone levels - they are usually lower in the morning and after a meal.
I've changed my diet and am eating no more that 30 net grams of carbs 90 grams of protein the rest of my 1400 come from fat. I was wondering if there is a way to really know if I am in ketosis without any strips, etc. My question is as a diabetic high blood sugars cause DKA but would having high ketosis make my blood sugars higher or are they unrelated? However, since you are a diabetic, you will need to get your medication adjusted - talk to your doctor before following the diet. I am getting very discouraged because my ketosticks were showing me levels between the moderate to large ketos levels.
As a complication, high blood pressure may develop early during the course of chronic kidney disease and is associated with adverse outcomes—in particular, faster loss of kidney function and development of cardiovascular disease.
Adverse outcomes of high blood pressure in chronic kidney disease include faster decline in kidney function and cardiovascular disease. Based on epidemiological data from the National High Blood Pressure Education Program and the National Health and Nutrition Examination Surveys, the rates of detection, treatment, and control of high blood pressure have improved dramatically over the past five decades. The goal of this guideline is to provide a selected review of the literature relating high blood pressure to adverse outcomes of chronic kidney disease and to describe the association of the level of GFR with high blood pressure, as reported in NHANES III.
The Sixth Report of the Joint National Committee for the Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC-VI) classifies categories of blood pressure levels as shown in Table 71. In the general population, there is a strong, graded relationship between the level of blood pressure and all-cause mortality and fatal and nonfatal cardiovascular disease. Numerous epidemiological studies and clinical trials have shown a relationship between the level of blood pressure and faster progression of diabetic kidney disease.
The Modification of Diet in Renal Disease Study showed a significant relationship between the rate of decline in GFR and level of blood pressure among patients with predominantly nondiabetic kidney disease. A relationship between level of blood pressure and progression of kidney disease has now been shown among kidney transplant recipients. Association of systolic blood pressure at 1 year with subsequent graft survival in recipients of cadaveric kidney transplants.
The prevalence of cardiovascular disease and related outcomes in patients with decreased GFR has not been evaluated in large-scale epidemiological studies, and little is known about CVD mortality and morbidity in these patients. Patients with chronic kidney disease have a high prevalence of high blood pressure, even when GFR is only mildly reduced (S). High blood pressure was defined as classification by study investigators based on patient history (including the use of antihypertensive drugs) and review of medical records. In this study, high blood pressure was defined by patient history (including the use of antihypertensive medications) and medical records, rather than the level of blood pressure.
Predicted prevalence of high blood pressure among adult participants age 20 years and older in NHANES III, 1988 to 1994. Among patients with lower GFR, the prevalence of high blood pressure is similar to that observed in the MDRD Study.
Among individuals with decreased kidney function and high blood pressure, 75% received treatment. Specific recommendations for evaluation and management of high blood pressure in chronic kidney disease are beyond the scope of this guideline. Another limitation is the lack of large-scale cohort studies and clinical trials correlating blood pressure levels to subsequent loss of GFR and cardiovascular disease events. Since many patients with chronic kidney disease are not detected until late in the course, studies that rely on clinical diagnosis are subject to misclassification.
Providers must be aware of lower recommended target levels for blood pressure for patients with chronic kidney disease, specific recommendations for classes of antihypertensive agents, and the role of nonpharmacologic therapy.
First, glucose oxidase catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. False negative results may be obtained with the presence of levodopa, ascorbic acid, glutathione, and dipyrone. The resulting color ranges from tan when no reaction takes place, to purple for a positive reaction. A positive reaction is indicated by a color change from yellow through green and then to greenish-blue.
The diazonium compound in turn couples with N- (l-naphthyl) ethylenediamine in an acid medium and the resulting color is pink. The esterases cleave a derivatized pyrazole amino acid ester to liberate derivatized hydroxy pyrazole. In the presence of an indicator, the color changes from deep blue in urine of low ionic concentration. Specific gravity is also increased with the glucose concentration in the urine and highly buffered alkaline urines may also cause low reading results.


You can check out my post here to see more about health effects of ketogenic diets with links to relevant research. The level of ketones in ketoacidosis are 3-5 times higher than in ketosis resulting from a ketogenic diet. Depending on how long you have been in ketosis, your body produces different types and amounts of ketones and you may not be able to detect acetoacetate when keto-adapted. The reasoning they gave was that ketones are, in fact, calories which are made from the breakdown of fat in the liver.
As I've explained above, more ketones won't help you burn significantly more calories - no studies show such effects. By the time they become keto-adapted, which takes 3-4 weeks, most of them understand what to eat and what to avoid without any real need to measure the precise level of ketone bodies.
When I started, I used Ketostix to find out when I was in ketosis and what my net carbs limit should be. In the end, what really matters is not ketones but the effects of low-carb diets: weight loss and improved health. Avoid too many chewing gums and mints, as it may put you out of ketosis; there may be hidden carbs affecting your blood sugar.
I am loosing inches since not much weight to go--more just burning the fat and being full of energy--both mental and physical. Some people have naturally high ketone levels and they also vary depending on how long you've been following the diet. The appropriate evaluation and management of high blood pressure remains a major component of the care of patients with chronic kidney disease. Guideline 13 describes the relationship of high blood pressure to progression of kidney disease.
Optimal levels of systolic and diastolic blood pressure are defined as less than 120 and 80 mm Hg, respectively. Regression lines relating the estimated mean GFR decline over 3 years to mean follow-up MAP for groups of patients defined according to baseline proteinuria.
Ranges of systolic blood pressure value in mm Hg and number of patients studied in the subgroups are indicated. Several studies have shown a high prevalence of left ventricular hypertrophy (LVH) in patients with decreased GFR and patients beginning dialysis. In addition to GFR level, the prevalence of high blood pressure was significantly greater among men and individuals with higher body mass index, black race, and older age. The investigation of antihypertensive agents to prevent or delay the progression of chronic kidney disease and development of cardiovascular disease is a rapidly evolving.
The strong relationship between prevalence of high blood pressure and GFR level observed in NHANES III, irrespective of diagnosis of chronic kidney disease, is especially important in confirming the link between decreased GFR and high blood pressure. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue through greenish-brown, and brown to dark-brown. However, the combinations of such ketone levels and low glucose levels are metabolically improbable. If the test color appears somewhat mottled at higher glucose concentrations, match the darkest color to the color on the reagent pad.
The sensitivity may he reduced in urine with high specific gravity and ascorbic acid content. The interpretation of results is also difficult in turbid urine specimens.For more information on protein in your urine please click here. Any degree of pink color is considered positive, however, pink spots or pink edges should not be interpreted as a positive result.
Comparison of the reagent pad against a white background may aid in the detection of low levels of nitrite.
If you want to test yourself daily, it will cost you $150 per month plus the cost of the meter. One explanation may be that high levels of ketones in the bloodstream may slightly raise insulin and block the release of free fatty acids from fat cells. These days, my daily net carbs intake varies from 30 to 60 grams depending on how active I am. Ketone levels tend to be lower while your glucose levels higher so you won't get representative numbers. Since both parents had died with cancer, I was told there was a good chance the spots might be cancerous. I am using the Myfitnesspal to track my daily MACROS but I am to the point that I really want to give up!
Usually, when you start, your levels will be higher simply because your body doesn't utilise ketone bodies as well as someone who is keto-adapted. Among patients with chronic kidney disease, there is also substantial evidence of a relationship between elevated levels of blood pressure and cardiovascular risk. Thus, clinical trials may be required to determine the optimal level of blood pressure to prevent or slow progression of chronic kidney and development of cardiovascular disease.
However, cross-sectional studies do not permit determination of the causal relationship between these variables.
The appearance of green spots on the reagent test area indicates the presence of intact erythrocytes in the urine. False positive results may be obtained from the presence of diagnostic or therapeutic dyes in the test urine. In addition, high blood pressure is associated with a greater rate of decline in kidney function and risk of development of kidney failure.
Table 73 shows the relationship between mean arterial pressure and various cardiovascular disease outcomes in a prospective cohort of incident dialysis patients.260 Left ventricular hypertrophy and congestive heart failure were both strongly associated with subsequent mortality.
Thus, it appears that additional efforts will be necessary to lower systolic blood pressure. In addition, the role of non-pharmacologic therapy for the treatment of high blood pressure, and as adjuncts in the prevention and treatment of cardiovascular disease, are also under investigation. Thus, they cannot determine whether high blood pressure is a cause or a complication of chronic kidney disease, or whether both high blood pressure and decreased GFR are caused by a third factor, such as aging. On the other hand, if you are on the Restricted Ketogenic Diet and numbers matter to you, a blood ketone meter may be the best and only option you have. The medical place also took that specifically for ketones--they are guiding me in my ketogenic diet.
However, the optimal level of blood pressure to minimize adverse outcomes for cardiovascular and kidney disease has not been established. However, lower rather than higher blood pressure was associated with a higher risk of death.
Nonetheless, the data from both the MDRD Study and NHANES III show a high prevalence of high blood pressure among persons with decreased GFR, justifying the emphasis on monitoring and treatment of high blood pressure in patients with chronic kidney disease. Does this mean the diet is not working for me? FYI, I have been on low calorie diet for the past 10 months before starting keto and I have been engaging in intense cardio and weight training for the past 11 months. I am not saying infinitvely that the diet cured my possible cancer spots, but it sure went a long way to getting me back to good health, and to shrinking my enlarged liver back to health, and who knows if that isn't a cure in cancer in itself, right? So just wanted to thank you for caring enough to post about this diet.
While I do have the blood testing kit, I have not used it yet since the strips are so pricey but my doctor ordered beta hydroxybutyrate test--I don't yet have that result.
