Is The Ketogenic Diet Appropriate for YOU?
The ketogenic diet, in the most basic definition, puts your body into ketosis. A diet created ~100 years ago to basically mimic the body’s fasting mode knowing this can be effective treat seizures. Essentially, when we’re fasting our bodies are consuming a very high fat diet. The fat, however, is coming from our stored body cells. The 4:1 fat to protein and carbohydrate ratio is 80-90% fat of total kcal, 10% protein, and a minimal amount of carbohydrate. This diet will cause blood glucose to lower, hence, insulin levels to lower, as well. This initiates the process, where the liver starts ketogenesis, making energy molecules called ketones. .
As one ages, the brain’s ability to utilize glucose as fuel also declines with age. Research has shown that ketone metabolism remains intact as we age, which argues that ketones can be an important fuel as we get older to maintain that energy supply to the brain. In neurodegenerative diseases it is very common to have glucose metabolism disruption in the brain, where these pathways are altered. Therefore, it can be a good idea to have this backup fuel on board in the form of ketones. Many of these disorders are defects in glucose metabolism pathways, such as glycolysis, but ketones bypass glycolysis and enter metabolic pathway at the level of the Krebs cycle. Ketones are the most efficient energy substrate that makes more ATP per O2 consumed. Speaking about the most energy demanding organ in the body, the brain, especially with an age condition where the brain is limited to its ability to use its normal fuel as glucose, ketones are beneficial. .
What about the Ketogenic diet without any metabolic disorders? There’s a lot of data that shows it works for many people, especially for those that may be “carbohydrate intolerant” In other words those on a high carb diet that may put on excess weight, abdominal fat, or maybe have some insulin resistance.
