While the relationships between seizure activity, oxidative stress and neuronal injury have yet to be clarified, previous studies have indicated that defects in antioxidant systems may contribute to seizure genesis and epileptogenesis (Cock, 2002; Patel, 2004; Liang & Patel, 2006; Shin et al, 2008). Earlier, the effects of a KD on mitochondrial ROS generation were discussed. Are there other mechanisms through which oxidative stress can be attenuated in epileptic brain?

One of the nagging unresolved questions regarding ketone bodies is whether they correlate with seizure control. Recent studies have suggested that under certain conditions and in specific models, blood levels of ketones do not in fact correlate well with anticonvulsant effects (Hartman & Vining, 2007). However, ketone levels are known to vary considerably during the circadian cycle, mostly as a consequence of feeding schedules and subsequent metabolism of foodstuffs (DeGasquet et al., 1977). Despite numerous studies highlighting ketonemia following KD treatment, we still do not know what the true brain concentrations are, especially in the microenvironment of the highly metabolically active synapse. Moreover, there are other studies suggesting that high ketone body levels are not necessary for clinical efficacy of a high-fat diet against medically refractory epilepsies (Pfeifer & Thiele, 2005).

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.

Given these observations, would it be practical to package acetoacetate or acetone into a pill? While ketone bodies in situ are likely to influence local cellular bioenergetics, there are profound logistical constraints precluding ease of administration in humans to achieve comparable low millimolar concentrations observed in clinical practice (Hartman & Vining, 2007). Acetoacetate is highly unstable, as it has an immediate tendency to spontaneously decarboxylate, and acetone is a well known solvent that can cause significant mucosal irritation. Finally, oral ingestion of β-hydroxybutyrate formulations to achieve such concentrations may not be readily achievable (Smith et al., 2005). These considerations pose not insignificant challenges toward the design of a ketone pill.
1 bulan rencana keto diet
Pilihlah lemak yang sehat termasuk lemak dari kelapa (santan, minyak kelapa), minyak zaitun, alpukat, chia, kacang rendah karbo (almond, kenari). Sebisa mungkin menghindari lemak dari hewan yang disuntik hormon, mengandung GMO, serta makanan proses dalam kemasan dengan tambahan kimia sintetik (perasa, pewarna, pengawet). Hindari juga minyak yang mengandung transfat seperti minyak canola, kedelai dan bunga matahari.

Glutathione is an endogenous tripeptide antioxidant whose function is to prevent free radical-mediated cellular injury (Schulz et al., 2000). It is found in nearly every cell in the body, and almost exclusively in its reduced form (GSH) due to the constitutive activity of glutathione reductase which converts it from the oxidized state, glutathione disulfide (GSSG). Under conditions of oxidative stress, glutathione reductase is inducible, and hence is able to increase the reducing equivalents essential to neutralize unstable molecules such as reactive oxygen species (Schulz et al., 2000).

In most instances, we eat because its meal time or it has been several hours since we last ate. Some experts recommend eating when you are hungry, stop when you are already full, and simply enjoy every mouthful. However, for you to get to that desired ‘keto’ state, you must keep track and count carbs and calories in order to get the hang of what is in your food and what you are putting into your body. So without further ado, here are five keto diet apps that will help you monitor your progress and discover new delectable recipes.
