Ketogenic Diet Alleviates Acute Radiation-Induced Intestinal Injury through JAK2/STAT3/RORγt/IL-17A Signaling Pathway via Gut Microbiome

ABSTRACT: This study demonstrates that ketogenic diet (KD), a high-fat and low-carbohydrate dietary regimen, exerts protective effects against RIII through dual mechanisms involving microbial regulation and inflammatory pathway inhibition.

Ketogenic diet versus standard high-carbohydrate nutrition in sepsis: a randomized controlled trial

Project description:Rationale: Sepsis patients suffer from severe metabolic and immunologic dysfunction that may be amplified by standard carbohydrate-based nutritional regimes. We therefore hypothesize that a ketogenic diet improves sepsis treatment. Objectives: We investigated the safety and feasibility of a ketogenic diet in sepsis patients. Methods: We conducted a monocentric open-labeled randomized controlled trial (DRKS00017710) enrolling adult sepsis patients randomly assigned to either ketogenic or standard high-carbohydrate diet for 14 days with follow-up until day 30. The primary outcome measure was β-hydroxybutyrate serum concentration on day 14. Secondary outcomes included safety, clinical and immunological changes. Measurements and Main Results: 40 critically ill septic patients were assigned to the study groups. Increase in β-hydroxybutyrate concentrations from baseline to day 14 was markedly greater under ketogenic diet (1.2 ±0.9) compared to controls (-0.3 ±0.4); estimated mean difference 1.4 (95%-CI 1.0-1.8; p<0.0001). During ketogenic diet, no patient required insulin treatment beyond day 4, whereas 35% to 60% of control patients did (p=0.0095). Metabolic side effects were not observed under ketogenic diet. Ventilation-free (IRR 1.7; 95%-CI: 1.5 to 2.1; p<0.0001), vasopressor-free (IRR 1.7; 95%-CI: 1.5 to 2.0; p<0.0001), dialysis-free (IRR 1.5; 95%-CI: 1.3 to 1.8; p<0.0001), and ICU-free days (IRR 1.7; 95%-CI: 1.4 to 2.1; p<0.0001) significantly increased in patients under ketogenic diet. There was no difference in 30-day mortality. Analyses indicated favorable changes towards immune homeostasis. Conclusions: Ketogenic diet is a feasible and safe nutritional regimen in septic patients promoting recovery from sepsis-related organ dysfunction and could become a new tool in modern treatment concepts.

Gene expression changes in ketogenic and high-fat diets

Project description:The ketone body β-hydroxybutyrate (BHB) is produced during dietary restriction, fasting, and exercise. A ketogenic diet (KD) results in long-term production of BHB outside of these contexts. We sought to determine a protein-matched, non-obese ketogenic diet (KD) would affect the longevity and healthspan of C57BL/6 male mice. We find that feeding KD every-other-week to prevent obesity (cyclic KD) reduces mid-life mortality but does not affect maximum lifespan. Similar feeding of a non-ketogenic high-fat/low-carbohydrate (HF) diet may have an intermediate effect on mortality. Cyclic KD improves memory performance in old age, while modestly improving composite measures of healthspan. RNAseq gene expression analysis identifies down-regulation of insulin, TOR, and fatty acid synthesis pathways as possible longevity mechanisms common to KD and HF. However, up-regulation of fasting-related PPARα target genes is unique to KD, consistent across tissues, and preserved in old age, suggesting a mechanism for an incremental benefit from KD. In all, we show that a non-obese ketogenic diet improves survival, memory, and healthspan into old age. These gene expression studies were carried out on 12 month-old male C56BL/6 mice from the NIA Aged Rodent Colony, habituated to AIN-93M control diet and then either maintained on this diet or switched for one week to a 75% kcal fat non-ketogenic high-fat diet or a 90% kcal fat ketogenic diet (all diets with 10% kcal from carbohydrates). Tissues were harvested in the middle of the nighttime feeding period (MN-3am).

Transcription profiling of mouse livers from animals fed a ketogenic diet (KD), a diet high in fat and low in carbohydrates

Project description:Analysis of liver gene transcription during feeding of a ketogenic diet. Ketogenic diets may alter physiologic and metabolic profiles in a direction that favors weight loss. C57BL/6J mice were maintained for six weeks on either chow or ketogenic diet. Mice eating KD had lower weights, 90% reduction in insulin levels and increased energy expenditure compared to animals fed chow. Despite consumption of a very high fat diet serum lipids remained normal. Here we show that consumption of KD shifted liver metabolism to drastically increased fatty acid oxidation. Concurrently, expression of genes involved in fatty acid synthesis were markedly suppressed. Reference: A high fat, ketogenic diet induces a unique metabolic state in mice.

Experiment Overall Design: Eight week old C57BL/6 mice were fed either chow (Labdiet 5008, Pharmserv) or KD (F3666, Bio-Serv) for six weeks. Livers were harvested in the morning in ad lib fed animals. Total RNA from 2-3 animals in each group was used for Affymetrix analysis.
