Article Abstract
Ketogenic diets, which are carbohydrate-restricted high-fat diets, may have therapeutic effects on various diseases, including cancer. However, ketogenic diets are often not standardized and, therefore, results are difficult to interpret. We previously investigated the usefulness of ketogenic diets in cancer therapy, where ketogenic formulas (KF) were used as supplements to enhance blood ketone bodies; however, the amount of KF was determined empirically with reference to blood ketone bodies levels. Here, to determine a standardized optimal amount of KF, we investigated temporal changes in blood ketone bodies (acetoacetic acid (AcAc), β-hydroxybutyrate (BHB)) and safety in 20 healthy individuals when KF was taken repeatedly under the conditions of a ketogenic diet (UMIN000034216). The diurnal variation in total ketone bodies, and AcAc and BHB levels significantly increased after lunch and after dinner, on the 4th day of KF administration. There were no significant safety issues related to KF in the context of anthropometric, metabolic, nutritional, urological and gastrointestinal parameters. In addition, ketogenic diets lead to changes in gut microbiota. KF showed a decrease in phylum . Our study provides baseline data of the usefulness of KF in a ketogenic diet.

Ketogenic Diet Mitigates Age-Related Cognitive Decline and Neuroinflammation in Rats, While Antibiotics Exacerbate Brain Health Risks.

The ketogenic diet (KD), a high-fat, low-carbohydrate regimen, has been shown to exert neuroprotective effects in various neurological models. This study explored how KD-alone or combined with antibiotic-induced gut microbiota depletion-affects cognition and neuroinflammation in aging. Thirty-two male rats (22 months old) were assigned to four groups (n = 8): control diet (CD), ketogenic diet (KD), antibiotics with control diet (AB), and antibiotics with KD (KDAB).

A ketogenic diet (KD) has shown promise as an adjunctive therapy for neurological and neuropsychiatric disorders, including bipolar disorder and major depressive disorder (MDD). We examined tolerance for a KD in young adults with MDD and assessed symptoms of depression and metabolic health. Students (n = 24) with a confirmed diagnosis of MDD at baseline receiving standard of care counseling and/or medication treatment were enrolled in a 10-12 week KD intervention that included partial provision of ketogenic-appropriate food items, frequent dietary counseling, and daily morning tracking of capillary R-beta-hydroxybutyrate (R-BHB).

Purpose: Ketogenic diet therapy (KDT) has been successfully used as an effective management option for drug resistant epilepsy (DRE) since the 1920 s. The ketogenic formulation studied here (KetoCal) is nutritionally complete, very high in fat, and low in carbohydrates and has played a crucial role in supporting the implementation of KDT for over twenty-five years. This scoping review aims to synthesise the existing literature regarding the safety, acceptability, and efficacy of the ketogenic formulation in supporting the management of DRE.

Dietary intake has an important influence on rates of fuel use during exercise, but the extent to which short-term diet changes affect peak fat oxidation (PFO) and the intensity at which this occurs (Fat) is unknown. This study examined the impact of diet-induced changes in substrate availability on PFO and Fat and the expression of key lipid-regulatory genes and proteins in skeletal muscle. Forty moderately to well-trained males (27 ± 5 years, V̇O 56.

Purpose Of The Review: This review aimed to summarize current evidence on the effectiveness of medical nutrition therapy (MNT) in the management of obesity and endometriosis, with a focus on dietary patterns such as the Mediterranean and Ketogenic diets, as well as nutritional supplementation. Additionally, it highlights the central role of the clinical nutritionist in implementing individualized, evidence-based interventions within multidisciplinary care.
Recent Findings: Although the literature reports the existence of an inverse relationship between risk of endometriosis and body mass index, clinical evidence jointly reports that a condition of obesity is associated with greater disease severity.
