A ketogenic diet is very high in fats, low in carbs and moderate in protein. A keto breakfast, for example, might involve mixing your coffee with coconut oil, heavy cream and butter, and scrambling eggs with cream cheese, adding a side of smoked salmon for protein. Ketones come from the breakdown of fat when there are not enough carbohydrates to keep the blood glucose within normal limits. It is known that as we age, less glucose is able to cross the blood-brain barrier in order to fuel the brain. The ketogenic diet provides a way for ketones to take up the energy slack. Sounds great, right? According to Ed Blonz, Ph.
Another biochemical feature of the KD is the decrease in glycolytic flux linked with the decrease of the energy value during the days following the diet. Dinner was usually a simple protein — a piece of fish adding capers to the yummy baked salmon with lemon or meat roast chicken, roast beef — with a salad and vegetables always with butter or a cheese sauce. Zhang Y. Suppression of oxidative stress by beta-hydroxybutyrate, an endogenous histone deacetylase inhibitor. Effects of low-carbohydrate vs low-fat diets on weight loss and cardiovascular risk factors: a meta-analysis of randomized controlled trials. Morning coffee and afternoon tea had full-fat cream and a spoonful of coconut oil. Jpn J. Later on, KBs enter the bloodstream and are available for brain, muscle, and heart, where they generate energy for cells in mitochondria [ 51 ]. Ultimately, reducing inflammation could be one of the most crucial AD modifying effects of a KD. Reprints and Permissions. The observation continued for 28 days.

Although the mechanism of the underlying pathology is not fully uncovered, in the last years, there has been significant progress in its understanding. Due to a lack of effective prevention and treatment strategy, emerging evidence suggests that dietary and metabolic interventions could potentially target these issues. The ketogenic diet is a very high-fat, low-carbohydrate diet, which has a fasting-like effect bringing the body into a state of ketosis. Moreover, their production may enhance mitochondrial function, reduce the expression of inflammatory and apoptotic mediators. It is a heterogeneous and multifactorial disorder, characterized by cognitive impairment with a progressive decline in memory, disorientation, impaired self-care, and personality changes [ 2, 3 ]. The most common symptom present at the beginning of AD is associated with short term memory deficit, which affects daily activities [ 3 ]. Moreover, patients with AD present mitochondrial dysfunction and metabolic changes, such as impaired glucose utilization in the brain glucose hypometabolism [ 5 ].
