More About The Keto Diet and Ketosis
What does Keto Mean?
Keto
The work “Keto” in a Ketogenic diet comes from the fact that the diet provides the body the ability to produce small fuel molecules called “Ketones.” Ketones are an alternative fuel source for the body, typically used when blood sugar (glucose) is in short supply. Ketones are produced if you eat very few carbs and moderate amounts of protein. Carbs stimulate insulin and quickly elevate blood sugar. It is important to keep Protein intake at moderate levels as protein will also have an insulin effect and can raise blood sugar (much less that that from carbs).
The liver produces ketones from fat and these ketones then serve as a fuel source throughout the body. The brain consumes lots of energy every day, and it can’t run on fat directly. It can only run on glucose or ketones. Interestingly, ketones are the preferred fuel for the brain.
On a ketogenic diet, your entire body switches its fuel source to run primarily on ketones from burning fats. When insulin levels become very low, fat burning increases dramatically and it becomes easier to burn stored bodyfat. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy and this may help keep you alert and focused.
When the body produces ketones, it enters a metabolic state called ketosis. The fastest way to get there is by fasting (i.e., not eating anything). The problem is that prolonged fasting has detrimental effects. The advantage of the Keto diet is that it puts the body into ketosis and can be eaten indefinitely. It has many of the benefits of fasting, including weight loss, without having to fast.
