PURPOSE OF REVIEW: To highlight recent developments in research regarding nutrition therapies for type 2 diabetes mellitus (T2DM) with a focus on the different approaches of the Nordic diet and the ketogenic diet. RECENT FINDINGS: Recent short-term studies have revealed that similar beneficial outcomes are seen after different dietary treatments for T2DM, with different approaches resulting in comparable weight loss and impacts on metabolic factors. SUMMARY: More individualized approaches in nutrition therapy should be considered for T2DM patients and clinical guidelines should reflect this...

Epilepsy is a neurological condition that affects 1% of the world population. Conventional treatments of epilepsy use drugs targeting neuronal excitability, inhibitory or excitatory transmission. Yet, one third of patients presents an intractable form of epilepsy and fails to respond to pharmacological anti-epileptic strategies. The ketogenic diet is a well-established non-pharmacological treatment that has been proven to be effective in reducing seizure frequency in the pharmaco-resistant patients. This dietary solution is however extremely restrictive and can be associated with complications caused by the high [fat]:[carbohydrate + protein] ratio...

BACKGROUND: Low-carbohydrate, high-fat and ketogenic diets are increasingly adopted by athletes for body composition and sports performance enhancements. However, as yet, there is no consensus on their efficacy in improving performance. There is also no comprehensive literature on athletes' experiences while undertaking this diet. The purpose of this pilot work was two-fold: i. to examine the effects of a non-calorie controlled ketogenic diet on body composition and performance outcomes of endurance athletes, and ii...

Americans have embraced a large number of diets in an attempt to manage obesity, improve quality of life, and address specific health problems. Among diets developed to address health problems, the ketogenic diet has had a long and variable history. Developed in the 1920s by a faith healer to help children with epilepsy, this diet induces a state that mimics carbohydrate starvation. As medications became available and effectively addressed seizures, the diet fell out of favor. During the last few decades, researchers and clinicians have learned that it can be useful in children and adults with refractory epilepsy and a variety of other conditions...

REVIEW

Dietary interventions are the cornerstone of obesity treatment. The optimal dietary approach to weight loss is a hotly debated topic among health professionals and the lay public alike. An emerging body of evidence suggests that a higher level of adherence to a diet, regardless of the type of diet, is an important factor in weight loss success over the short and long term. Key strategies to improve adherence include designing dietary weight loss interventions (such as ketogenic diets) that help to control the increased drive to eat that accompanies weight loss, tailoring dietary interventions to a person's dietary preferences (and nutritional requirements), and promoting self-monitoring of food intake...

There is a significant body of research undertaken in order to elucidate the mechanisms underlying the pathology of Alzheimer's disease (AD), as well as to discover early detection biomarkers and potential therapeutic strategies. One such proposed biomarker is the calcium binding protein S100β, which, depending on its local concentration, is known to exhibit both neurotrophic and neuroinflammatory properties in the central nervous system. At present, relatively little is known regarding the effect of chronic S100β disruption in AD...

Status epilepticus (SE) is considered one of the major serious forms of epilepsy with high mortality rate. Since the currently available antiepileptic drugs have low efficacy and high adverse effects, new more efficient and safe therapies are critically needed. There is increasing evidence supporting dietary and alternative therapies for epilepsy, including the ketogenic diet, modified Atkins diet, and omega-3 fatty acids. Recent studies have shown significant prophylactic and therapeutic potential of vitamin D (vit-D) use in many neurological disorders...

Epilepsy is a chronic neurological disorder that affects approximately 50 million people worldwide. Ketogenic diet (KD) can be a very effective treatment for intractable epilepsy. Potential mechanisms of action for KD have been proposed, including the re-balance among excitatory and inhibitory neurotransmission and decrease in the glycolytic rate in brain cells. KD has been shown to have an effect on the expression pattern of monocarboxylate transporters (MCT), however, it is unknown whether MCT transport activity is affected by KD and linked to the reduction of seizures during KD...

Over the past decade we have consistently shown that ketosis is neuroprotective against ischemic insults in rats. We reported that diet-induced ketotic rats had a significant reduction in infarct volume when subjected to middle cerebral artery occlusion (MCAO), and improved survival and recovery after cardiac arrest and resuscitation. The neuroprotective mechanisms of ketosis (via ketogenic diet; KG) include (i) ketones are alternate energy substrates that can restore energy balance when glucose metabolism is deficient and (ii) ketones modulate cell-signalling pathways that are cytoprotective...

The ketone metabolite, β-hydroxybutyrate (βOHB), is reported neuroprotective after spinal cord injury (SCI) in rats, but the underlying mechanism remains unknown. The present study aims to investigate effects of βOHB on suppression of oxidative stress and inhibition of class I histone deacetylases (HDACs) in in-vivo and in-vitro models. Rats were fed with ketogenic diet (KD) or standard diet (SD) 3 weeks. A C5 hemi-contusion injury was applied to these animals on the 14th day of experiment, and spinal cord samples were harvested on the 1st, 3rd and 7th day after SCI, respectively...

OBJECTIVE: The medium-chain triglyceride (MCT) ketogenic diet contains both octanoic (C8) and decanoic (C10) acids. The diet is an effective treatment for pharmacoresistant epilepsy. Although the exact mechanism for its efficacy is not known, it is emerging that C10, but not C8, interacts with targets that can explain antiseizure effects, for example, peroxisome proliferator-activated receptor-γ (eliciting mitochondrial biogenesis and increased antioxidant status) and the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor...

The present study aimed to investigate the anticonvulsant effects of β-hydroxybutyrate (BHB) in a kainic acid (KA)-induced rat seizure model. The concentrations of BHB and glucose were detected in the blood prior to exogenous BHB administration. Three different doses of BHB (2, 4 and 8 mmol/kg) were then injected into male Wistar rats intraperitoneally, and the concentrations of BHB and glucose in the blood were detected. Rats received 0.9% normal saline intraperitoneally at a dose of 4 ml/kg as a control...

Diets that increase production of ketone bodies to provide alternative fuel for the brain are evolving from the classic ketogenic diet for epilepsy devised nearly a century ago. The classic ketogenic diet and its more recent variants all appear to have similar efficacy with approximately 50% of users showing a greater than 50% seizure reduction. They all require significant medical and dietetic support, and there are tolerability issues. A review suggests that low-grade chronic metabolic acidosis associated with ketosis is likely to be an important contributor to the short term and long term adverse effects of ketogenic diets...

The treatment of obesity and cardiovascular diseases is one of the most difficult and important challenges nowadays. Weight loss is frequently offered and aimed at improving some of the components of the metabolic syndrome. Among various diets, carbohydrate restriction is popular, specifically ketogenic diets, which are very low in carbohydrates and usually high in fats and /or proteins. Results are controversial, but some benefits such as weight loss and improved glycemic control have been described. Nevertheless, these effects seem to be limited in time...

Adipose tissues considerably influence metabolic homeostasis, and both white (WAT) and brown adipose tissue (BAT) play significant roles in lipid and glucose metabolism. O-GlcNAc modification is characterized by the addition of N-acetylglucosamine to various proteins by O-GlcNAc transferase (Ogt), subsequently modulating various cellular processes. However, little is known about the role of O-GlcNAc modification in adipose tissues. Here, we report the critical role of O-GlcNAc modification in cold-induced thermogenesis...
