Studies show a ketogenic diet can slow and even reverse symptoms of memory loss and cognitive impairment throughout all the dementia stages. Ketones have been shown in studies to be neuroprotective, meaning they “defend” your brain from degenerating. Research clearly establishes a strong link between blood sugar disorders and the various dementia stages, including memory loss, mild cognitive impairment (MCI), and Alzheimer’s. The most predominate blood sugar disorders are insulin resistance and diabetes. In fact, the link is so obvious that some researchers have labelled Alzheimer’s disease as “type 3 diabetes.”
Because glucose and insulin mechanisms in the brain are so impaired by the time one enters into the dementia stages, a ketogenic diet may be a great natural intervention for Alzheimer’s as it can slow or even reverse symptoms. This is because the brain is now burning ketones for energy instead of glucose, which can help restore function.
