Although the mechanism of action of the ketogenic diet (KD) remains unknown, ketones have been used as a marker of efficacy. Acetoacetate, acetone, and beta-hydroxybutyrate can be measured in urine, blood, and breath. The value of these measures is reviewed in this paper. Future brain measures hold promise as markers of efficacy, but research focused on the mechanisms of the KD should help to d...

In 1928 (1) and again in 1931 (2) evidence was presented indicating that fasting Eskimos show a lesser degree of ketosis than normal persons living in the temperate zone. The period of fasting in 1928 was of 72 hours duration; in 1931 in two subjects it was 96 hours, in two others, 115 hours. The results showed that some measure of ketosis developed in all subjects, but was only appreciable in ...

In previous studies from our laboratory a positive correlation between elevated blood ketone levels and the survival time (ST) during hypoxia (4-5% oxygen) was observed in fasted and alloxan diabetic mice. To test the hypothesis that ketosis was somehow increasing the tolerance of mice to hypoxia, we induced ketosis by either oral (PO), intraperitoneal (IP), or intravenous (IV) 1,3-butanediol (...

Specifically 14C-labeled mevalonic acids were administered to rats in diabetic ketosis, and the distribution of 14C was determined in the hydroxybutyric acid each rat excreted. Also, the distributions of 14C were determined in hydroxybutyric acid formed by slices of livers and kidneys from rats in diabetic ketosis and incubated with the specifically labeled mevalonic acids. The distributions fo...

Opposing evidence exists for the source of hydrogen ions (H+) during ketoacidosis. Organic and computational chemistry using dissociation constants alpha equations all pertinent ionizable metabolites were used to (1) document atomic changes in chemical reactions ketogenesis ketolysis (2) identify sources quantify added fractional (~) H+ exchange (~H+e). All computations performed pH conditions ...

the possible relationships between trace elements, oxidative stress and subclinical ketosis during the transition period were evaluated in dairy cows. blood samples were obtained by jugular venipuncture at four times of the transition period: 3 weeks and 1 week before and 1 week and 3 weeks after calving. the highest concentrations of malondialdehyde (mda) and betahydroxybutyrate (bhb) were obs...

The ketogenic diet is a high-fat, adequate protein, low carbohydrate diet that has been used for the treatment of intractable childhood epilepsy since the 1920s. The diet mimics the biochemical changes associated with starvation, which create ketosis. Although less commonly used in later decades because of the increased availability of anticonvulsants, the ketogenic diet has re-emerged as a the...

The study was conducted on 145 buffaloes brought to Teaching Veterinary Clinical Complex, LUVAS from Hisar and adjoining villages, with signs of anorexia and decreased milk yield. Urine samples from buffaloes were screened for ketosis using two tests (Rothera’s test and Keto-Diastix-strip test). The disease was confi rmed in 24 buffaloes as primary ketosis on the basis of clinical signs (select...
