The earliest demonstration of direct in vivo effects of ketone bodies was made by Keith in the early 1930’s, when he determined that acetoacetate, when administered intraperitoneally in rabbits, prevented seizures induced by thujone (1933), a convulsant constituent found in many essential oils and an antagonist of GABAA receptors (Höld et al., 2000). This seminal observation was later confirmed in an audiogenic seizure-susceptible mouse model (Rho et al., 2002). More intriguingly, however, Likhodii and colleagues (2003) established the broad anticonvulsant properties of acetone in four different animal models, and when injected intraperitoneally, produced plasma and cerebrospinal fluid (CSF) concentrations consistent with those used to suppress seizures. These results confirmed and extended historical observations supporting an anticonvulsant action for acetone, through as yet undetermined mechanisms (Likhodii & Burnham, 2002). And in further support of this, other investigators found that acetone was detectable (up to a concentration of 0.7 mM) in the brains of fully controlled KD-treated patients with epilepsy using proton magnetic resonance spectroscopy (Seymour et al, 1999).
Pilihlah kualitas makanan yang baik seperti daging, karena pada Keto Diet memungkinkan Anda untuk mengkonsumsi daging dalam jumlah yang basar. Sehingga kualitas daging segar, hormon-free, sedikit lemak, dan tidak berbau sangatlah dianjurkan. Memilih berbagai varian daging dari daging ikan. Makan ikan jika memungkinkan karena pada ikan terdapat kandungan omega-3 yang tinggi.

Alternatively, if simple calorie restriction is sufficient to prevent seizure activity in patients, why not decrease total caloric intake, and not bother with the high-fat KD? However, from yet another perspective, one could consider combining the KD and calorie restriction (as has been done in animal studies). In rats fed a calorie-restricted KD, Bough and colleagues (2003) demonstrated exhibited greater paired-pulse inhibition in the dentate gyrus, elevated maximal dentate activation threshold, and an absence of “spreading depression”-like events compared with ad libitum-fed controls. These results suggest that treatment with a calorie-restricted KD may produce both anticonvulsant and anti-epileptogenic effects.
Dalam proses penurunan berat badan memang menu makanan yang sehat, baik dan bergizi perlu diperhatikan disamping itu juga perlunya mengatur pola makan. akan tetapi banyak orang tidak terlalu memperhatikan menu makanan dalam diet sehingga tidak sedikit yang gagal atau sudah berhasil tetapi kemudian berat badan naik kembali. oleh karena itu dalam diet selain melakukan aktivitas fisik juga harus didukung dengan menu makanan sehari-hari yang sehat agar berat badan tetap ideal.

What investigators have elucidated over the past decade or so is that a variety of molecular, genetic, cellular, and metabolic factors are likely contributory to the clinical effects of the KD. As a generalization, it is becoming widely accepted that the mechanistic underpinnings of the KD are likely multiple, parallel, and possibly synergistic (Bough & Rho, 2007).

Given these findings, it is not surprising that investigators have studied the effects of dietary supplementation with PUFAs alone, to determine whether these substrates can render an anticonvulsant effect. Early case reports suggested that seizures might be better controlled with this approach (Schlanger et al., 2002). However, a recent randomized trial in adult patients with epilepsy failed to demonstrate superiority of a PUFA supplement (EPA) plus DHA, 2.2 mg/day in a 3:2 ratio) over placebo (Bromfield et al., 2008). Thus, the jury is still out as to whether PUFAs alone can mirror the clinical effects of the KD.
