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).

Furthermore, if the KD increases GABA levels in the brain, then such an effect is approximated by vigabatrin, an irreversible inhibitor of the degradative enzyme GABA-transaminase, as well as by tiagabine, a GABA re-uptake blocker that interferes with presnaptic GABA transporters (White et al., 2007). Yet, the anticonvulsant profile of the KD is distinct from that of vigabatrin and tiagabine (Hartman et al., 2007). The general approach of deriving another pill that enhances brain GABA levels may not be relevant or viable, since many seizure types seem to be exacerbated by agents that contribute to enhanced tonic inhibition, and extrasynaptic GABA receptors that mediate tonic inhibition are more sensitive to elevated ambient GABA concentrations (Sazgar & Bourgeois, 2005). Indeed, increased GABAergic inhibition in the cortex appears to underlie the mechanism of synchronization and seizure generation in two mouse models of autosomal dominant nocturnal frontal lobe epilepsy (Klassen et al, 2006)

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.
