Calorie Restriction - like Effects of 30 Days of Resveratrol Supplementation on Energy Metabolism and Metabolic Profile in Obese Humans Cell Metabolism 2011 (Nov 2); 14 (5): 612 — 622 ~ FULL TEXT The result of just 30 days on resveratrol were impressive: (1) The same gene regulators (AMPK, SIRT1 and PGC - 1a) were activated in this study as are
activated by caloric restriction and resveratrol in mice and endurance training in humans.
For example, KBs were recently reported to act as neuroprotective agents
by raising ATP levels and reducing the production of reactive oxygen species in neurological tissues, 80 together with increased mitochondrial biogenesis, which may help to enhance the regulation of synaptic function.80 Moreover, the increased synthesis of polyunsaturated fatty acids stimulated
by a KD may have a role in the regulation of neuronal membrane excitability: it has been demonstrated, for example, that polyunsaturated fatty acids modulate the excitability of neurons
by blocking voltage-gated sodium channels.81 Another possibility is that
by reducing glucose metabolism, ketogenic diets may
activate anticonvulsant mechanisms, as has been reported in a rat model.82 In addition,
caloric restriction per se has been suggested to exert neuroprotective effects, including improved mitochondrial function, decreased oxidative stress and apoptosis, and inhibition of proinflammatory mediators, such as the cytokines tumour necrosis factor - α and interleukins.83 Although promising data have been collected (see below), at the present time the real clinical benefits of ketogenic diets in most neurological diseases remain largely speculative and uncertain, with the significant exception of its use in the treatment of convulsion diseases.
