Background. Very-low-carbohydrate ketogenic diets (VLCKDs) promote benefits for a range of health conditions. However, there is little research elucidating the ‘lived experience’ of individuals undertaking these diets, and the effects of keto-induction, during adaptation to these diets. Objective. This study aimed to evaluate the subjective experiences of people following a very low carbohydrate, ketogenic diet. Design. This paper describes the qualitative experiences of twenty-eight non-obese, non-diabetic participants, (2 males, 26 females: age ± SD: 35 ± 4 y) in a randomised controlled trial to test the effects of medium chain triglyceride (MCT) supplementation in a VLCKD on time to nutritional ketosis (NK), symptoms of keto-induction, and mood. The experience provided by the diet was rated by a free-form daily diary entry and post-study focus group. Diary entries and focus group transcription were coded inductively and grouped into common themes. Results. Twenty-three participants completed the 3-week study. Physical effects accounted for over 28% of references. Other results were categorised as; mood, energy and cognition (23%), satiety and hunger (16%), cravings and temptation (11%), and sleep (8%). Overall, 49% of references were classified as ‘positive’ with 8% neutral, and 43% negative. Positive impressions were higher after participants had achieved nutritional ketosis and negative impressions higher during keto-induction. Negative impressions, both concerning physical symptoms and feelings of mood and well-being, tended towards improvement over the course of the study, and positive impressions improved. However, there was a large variation in responses, and several respondents reported adverse effects throughout the study. Conclusion. Despite challenges, especially gastrointestinal effects, the overall perception of the diet was positive, and it provided benefits for wellbeing, mood, sleep, and sugar cravings which tended towards improvement over the course of the study. Negative experiences decreased as participants adapted to the VLCKD. Most participants continued post-study, using a lower-carbohydrate diet, due to these perceived benefits. Our findings suggest that the experience of a VLCKD is positive but variable. Further research on individual tolerance and response to low carbohydrate diets is warranted.

Abstract Purpose This pilot-controlled trial aimed to examine the feasibility and acceptability of hypnosis-derived communication (HC) administered by trained nurses during outpatient chemotherapy to optimize symptom management and emotional support — two important aspects of patient well-being in oncology. Methods The trial was conducted in two outpatient oncology units: (1) intervention site (usual care with HC), and (2) control site (usual care). Nurses at the intervention site were invited to take part in an 8-h training in HC. Participants’ self-ratings of symptoms and emotional support were gathered at predetermined time points during three consecutive outpatient visits using the Edmonton Symptom Assessment Scale and the Emotional Support Scale. Results Forty-nine patients (24 in the intervention group, 25 in the control group) with different cancer types/stages were recruited over a period of 3 weeks and completed the study. All nurses (N = 10) at the intervention site volunteered to complete the training and were able to include HC into their chemotherapy protocols (about ± 5 min/intervention). Compared to usual care, patients exposed to HC showed a significant reduction in physical symptoms during chemotherapy. In contrast, perception of emotional support did not show any significant effect of the intervention. Participants exposed to HC report that the intervention helped them relax and connect on a more personal level with the nurse during chemotherapy infusion. Conclusions Our results suggest that HC is feasible, acceptable, and beneficial for symptom management during outpatient chemotherapy. While future studies are needed, hypnosis techniques could facilitate meaningful contacts between cancer patients and clinicians in oncology.

AbstractKetogenic diet therapies are high-fat, low-carbohydrate diets designed to mimic a fasting state. Although initially developed nearly one century ago for seizure management, most clinical trials for the management of drug-resistant epilepsy in children as well as adults have been conducted over the last 3 decades. Moreover, ketogenic diets offer promising new adjunctive strategies in the critical care setting for the resolution of acute status epilepticus when traditional antiseizure drugs and anesthetic agents fail. Here, we review the history of ketogenic diet development, the clinical evidence supporting its use for the treatment of drug-resistant epilepsy in children and adults, and the early evidence supporting ketogenic diet feasibility, safety, and potential efficacy in the management of status epilepticus.

Low Carbohydrate

Low-carbohydrate and very-low-carbohydrate diets are often used as weight-loss strategies by exercising individuals and athletes. Very-low-carbohydrate diets can lead to a state of ketosis, in which the concentration of blood ketones (acetoacetate, 3-β-hydroxybutyrate, and acetone) increases as a result of increased fatty acid breakdown and activity of ketogenic enzymes. A potential concern of these ketogenic diets, as with other weight-loss diets, is the potential loss of fat-free mass (e.g., skeletal muscle). On examination of the literature, the majority of studies report decreases in fat-free mass in individuals following a ketogenic diet. However, some confounding factors exist, such as the use of aggressive weight-loss diets and potential concerns with fat-free mass measurement. A limited number of studies have examined combining resistance training with ketogenic diets, and further research is needed to determine whether resistance training can effectively slow or stop the loss of fat-free mass typically seen in individuals following a ketogenic diet. Mechanisms underlying the effects of a ketogenic diet on fat-free mass and the results of implementing exercise interventions in combination with this diet should also be examined.

ABSTRACT The ketogenic diet (KD), a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable while reducing side effects and making it available to larger group of refractory epilepsy patients. This review summarizes the history of the KD and the principles and efficacy of the classic ketogenic diet, medium-chain triglyceride(s) (MCT) ketogenic diet, modified Atkins diet, and low glycemic index treatment.

Abstract Background There is increasing interest in the use of ketogenic diets (KD) as adjuvant therapy for glioblastoma (GBM). Trial aims: i) investigate protocol feasibility; ii) assess patient/carer acceptability; iii) explore the decision-making of patients’ invited to participate in KEATING; and iv) inform phase III trial design. Methods Prospective, feasibility study, with embedded qualitative design randomised 12 newly-diagnosed GBM patients to three months of medium chain triglyceride ketogenic diet (MCTKD) or the modified ketogenic diet (MKD) during chemoradiotherapy. Primary outcome was retention; secondary outcomes included recruitment rate, dietary acceptability, progression free survival (PFS) and overall survival (OS). Semi-structured interviews were conducted with a representative sample of patients and relatives (n=15). Results Recruitment targets were achieved, but recruitment rate was low (28.6%). Retention was poor; only 4 of 12 completed the three-month diet (MCTKD n=3; MKD n=1). Median duration until discontinuing was 5.2 weeks (0–7 weeks; n=8). Participants made instantaneous decisions without deliberation: relatives supported diet implementation. Decliners made considered decisions factoring diet burden and quality of life. A three-month diet was undesirable to these patients. Median PFS was 11.4 weeks and OS was 67.3 weeks. Conclusion Recruitment to a ketogenic-glioblastoma trial is possible. To assess effectiveness in a phase III clinical trial, a six week intervention period is proposed. Future trials should optimise and adequately support the decision-making of patients. The role of relatives should not be underestimated.

Background Members of online bipolar disorder forums often report experiences of mood-stabilisation on the ketogenic diet, which has traditionally been used in the treatment of epilepsy. We examined the nature and extent of such reports. Aims To investigate associations between a ketogenic diet and mood stabilisation among individuals with bipolar disorder. Method We undertook an observational analytic study of free-text comments in online forums about mood effects of dietary interventions (ketogenic, omega-3 enriched or vegetarian) classified by a priori categories of change in mood stabilisation in 274 people with bipolar disorder. Results There were 141 (85.5%) free-text comments on ketogenic diets that reported a positive impact on mood stabilisation. Reports of significant mood stabilisation or remission of symptoms over a period were substantially higher for a ketogenic diet than for other diets (93/165, 56.4%, 95% CI 48.4–64.1) v. 14/94, 14.9%, 95% CI 8.4–23.7), odds ratio 7.4, 95% CI 3.8–14.1, P < 0.0001), many with detailed reports of the improvements experienced and several lasting for extended periods (months to years). Other reported associations included fewer episodes of depression (in 41.2%, 95% CI 30.6–52.4 of individuals); improved clarity of thought and speech (28.2%, 95% CI 19.0–39.0); increased energy (25.9, 95% CI 17.0–36.5); and weight loss (25.9%, 95% CI 17.0–36.5). Conclusions Despite the inherent limitations of the observational data based on self-reports posted online, the association strength and reports of sustained benefit support a hypothesis of a ketogenic diet being associated with beneficial effects on mood stabilisation. Caution should be exercised in interpreting this data until a controlled trial can be carried out to examine this hypothesis. These preliminary observations are generally consistent with a mitochondrial dysfunction component to bipolar disorder aetiology with ketones bypassing a block between glycolysis and the tricarboxylic acid cycle. Declaration of interest None.

BACKGROUND: Ketogenic diet is now in trend. But very less researches were conducted in India to check signicant effects on weight loss of Ketogenic Diet among overweight/obese adults compared to calorie restricted Low Fat diet. OBJECTIVE:To compare the effect of Very Low Carbohydrate Ketogenic (VLCK) diet and energy restricted Low-Fat (LF) diets on weight loss in overweight/obese healthy adults. Design: An interventional randomized controlled trial of 6 months was initiated. PARTICIPANTS: 113 overweight/obese adults with a body mass index of 25 kg/m2 or greater; with no abnormalities and more than 20 years of age. INTERVENTION: Among 113 overweight/obese adults, we conducted a six-month randomized controlled trial of two sets of dietary advice, each providing approximately 12,00-1500 calories per day but differing in protein, ber, fat and carbohydrate content. RESULTS: We found that dieters given VLCK advice tended to lose more weight than those given a LF diet. CONCLUSION: For short period of time VLCK diet is more effective than conventional LF diet for weight loss. But for long term effects further studies are required.

Ketogenic diets are high fat, moderate protein, low carbohydrate diets with carbohydrate content usually less than 50 g/day. They are a novel intervention in the management of obesity and there is emerging evidence that they are very effective. Evidence regarding the long-term efficacy and safety of this rather new and popular intervention is still emerging and there is a lack of data on the effect of this diet in specific populations such as breast feeding women. We describe a case of severe ketoacidosis in a non-diabetic breast feeding woman who was successfully treated with conservative measures. This case highlights the need by medical and dietetic professionals for extra caution in initiating special dietary measures in susceptible physiological states.
