One potential explanation for the anticonvulsant action of the KD argues that increased ATP synthesis should produce a positive bioenergetic balance, allowing stabilization of the resting membrane potential via enhanced activity of Na+-K+-ATPase (Bough & Rho, 2007). Several decades ago, De Vivo and colleagues (1978) reported that the KD increased the total quantity of bioenergetic substrates (such as adenosine triphosphate, or ATP) and elevated the energy charge in rat brain. These changes were purported to stabilize the cell membrane, especially in the face of excessive excitation. Consistent with these observations, a later human study utilizing magnetic resonance spectroscopic techniques indicated that patients with epilepsy fed a KD had elevated phosphocreatine to creatine levels in the brain (Pan et al., 1999). Recently, using cDNA microarray technology, increased expression of the mitochondrial ATP synthase β,D subunit in mouse brain was reported after KD treatment (Noh et al., 2004). And in the most comprehensive study of this kind to date, the KD was found to enhance mitochondrial biogenesis and significantly increase the number of transcripts encoding energy metabolism genes in rats (Bough et al., 2006). This increase in bioenergetic capacity enabled hippocampal slices from these animals to better withstand metabolic challenge from low glucose exposure. Taken together, the prevailing notion has been that increased energy production and reserve capacity enable greater resistance to neuronal hyperexcitability and hypersynchrony.

So, let us explain how this supplement works so you can understand what it does when it goes inside your body. First of all, it transforms all the fats in your body to pure energy. This is great since it makes you more attentive and focused in your daily life. The fats which have been present in your body for too long and are just contributing to weight gain will be broken down.
So, the natural question arises, do ketone bodies affect inhibitory (or excitatory) neurotransmission? Unfortunately, the answer is (at least for now) a fairly convincing no. Thio and colleagues (2000) showed that acute application of BHB and ACA did not affect: (1) excitatory post-synaptic potentials (EPSPs) and population spikes in CA1 pyramidal neurons after Schaffer collateral stimulation; (2) spontaneous epileptiform activity in the hippocampal-entorhinal cortex slice seizure model; and (3) whole-cell currents evoked by glutamate, kainate, and GABA in cultured hippocampal neurons.
Munculnya beragam jenis diet bisa bikin bingung. Berbagai manfaat dari setiap diet terdengar sangat menggoda, apalagi dengan klaim “efektif menurunkan berat badan”. Namun, jangan asal diet! Cari tahu dulu dengan jelas mengenai diet yang akan Anda jalani. Pastikan apakah sesuai dan aman untuk Anda. Salah satu jenis diet yang sedang banyak digemari yaitu diet keto. Diet keto adalah salah satu pola makan yang dianggap ampuh menurunkan berat badan secara cepat dan efektif.

Slimlinic Keto enhancements are clinically endorsed and guaranteed an item by FDA. The arrangement of this item is natural and advantageous. There is no scene of any bad reactions except if you are adversely affected by any substance present in the enhancement. Numerous individuals have insufficient quality in their invulnerable framework; they are progressively touchy. As indicated by the maker of Slimlinic Keto enhancements may give some regular suggestions in the early does. These signs and manifestations are:

Untungnya, beberapa variasi diet keto telah dikembangkan menjadi sedikit lebih fleksibel, dan lebih mudah bertahan dengan jangka panjang. Diet ketogenik tradisional atau standar menempatkan tubuh Anda ke dalam ketosis: Dalam keadaan metabolik ini, Anda membakar lemak (bukan karbohidrat) sebagai sumber bahan bakar utama Anda, dan itu mendorong hilangnya lemak. Pada diet keto yang dimodifikasi, tubuh Anda akan keluar dari ketosis, tetapi masih menurunkan berat badan dan lemak tubuh. Lihat panduan di bawah ini untuk melihat bagaimana masing-masing dari keempat jenis diet keto bekerja.

One highly studied mechanism implicated in the clinical benefits of calorie restriction involves sirtuins, a large and diverse family of enzymes that regulate gene expression. The first sirtuin, silent information regulator 2 (Sir2), was described in yeast. Sir2 is a class III histone deacetylase that uses the cofactor nicotinamide adenine dinucleotide (NAD+) in a catalytic reaction that releases nicotinamide (a feedback inhibitor) and O-acetyl ADP ribose (Imai et al. 2000; Marmorstein 2004; Sauve et al. 2006). It has been reported that increased Sir2 activity lengthens life span, and that calorie restriction increases Sir2 levels and does not promote longevity in SIR2 knockouts (Kaeberlein et al. 1999; Lin et al. 2000, 2004; Tissenbaum and Guarente 2001; Rogina and Helfand 2004). In mammals, calorie restriction increases the expression of Sirt1, the Sir2 mammalian ortholog, in various tissues, including brain. Resveratrol, a natural Sirt1 activator found in red wine, lengthens the life span of mice and prevents the age-related deterioration of their motor function (Cohen et al. 2004; Baur et al. 2006). Additionally, resveratrol stimulates AMP kinase activity in neurons (Dasgupta & Milbrandt, 2007), and more importantly, protects against kainic acid-induced seizures and oxidative stress in rats (Gupta et al., 2002).

So is the clinical effectiveness of the KD simply a matter of increasing energy stores? If this is the case, then would it not be a simpler matter to ingest creatine, a highly bioavailable and relatively safe oral supplement, and one that is increasingly demonstrated to promote health and longevity (Beal, 2003; Bender et al., 2007; Schapira, 2008)?
Thus, if fatty acids (and perhaps more specifically, polyunsaturated fatty acids or PUFAs), enhance mitochondrial uncoupling, and if this basic downstream mechanism is responsible for both anticonvulsant and neuroprotective effects (which has yet to be demonstrated), then could taking a chemical uncoupler such as 2,4-dinitrophenol (DNP) render the same effects? Of course, it is well known that DNP, a potent mitochondrial uncoupler that greatly increases the basal metabolic rate, and once used to treat obesity in the 1930’s, has a major untoward side-effect profile – namely, high fever and the risk of death. Clearly, if mitochondrial uncoupling were to represent the essential target, then less potent (and less toxic) compounds are required, and novel delivery systems need to be developed.

Diet keto atau disebut juga dengan diet ketogenik berasal dari kata keton. Keton adalah senyawa kimia yang dihasilkan dari pemecahan lemak oleh hati. Biasanya, energi diambil dari glukosa yang bersumber dari karbohidrat. Namun, dikarenakan rendah karbohidrat maka tubuh akan kekurangan glukosa. Alhasil, secara otomatis tubuh menggunakan cadangan energi dari senyawa lainnya, yaitu lemak.
