So, what exactly are these ketones and where do they come from?
As mentioned earlier, when your body exhausts its glucose reserves (glycogen), it will look for another alternative energy source.
This is when it gets digging into the body’s fat storehouse as stored fat can help to fuel the required energy for your cells. Since there is no glucose in the body, your liver will take in the stored fats and convert them into fatty acids.
These fatty acids are then broken down into functional compounds known as ketone bodies (otherwise known as ketones). Your body uses these ketones to provide energy to your body cells and brain cells. The best part is, when your blood ketone levels increase your appetite decreases.
The reason for improved energy is that your brain uses a different source to produce energy. Your liver generates three different types of ketone bodies, – Acetoacetate – Beta-Hydroxybutryate – Acetone Your body can fuel itself from ketones in two different ways: – Your body is capable of making its own ketones when you fast or when you increase your fat intake and reduce your carb-intake forcing the abstinence of glucose – You can also feed your body with actual ketones by consuming exogenous ketones (ketone supplements) When your body is on a ketogenic diet, it acts as a fat-burning machine as it switches its primary energy source from glucose to stored fat. This naturally leads to low insulin levels and the fat burning power increases as accessing the fat stores becomes easy. Your body is in ketosis when it produces ketones, and the fastest way to shift your body into ketosis is by fasting. But it is impossible to fast forever, and this led to the development of the ketogenic diet.
Is it possible to lose weight because the body enters into ketosis? When your body begins to burn stored fat into ketones, your body shifts into ketosis. But why will that make me reduce weight? I understand where you are coming from. Let me explain this to you with an example.
Imagine you have stored a pile of coal for the upcoming winter. When it is winter, you scoop up some of these coal piles into the furnace for heat. As you continue to use up all the coal, the pile gets smaller. Similarly, in ketosis your body burns the stored fat in your body and as it continues to utilize the stored fats (which is your extra flab, water weight, excess calories, etc.), you get smaller i.e. you reduce weight. The coal is the stored fat here and the heat you receive in winter is your energy. There are numerous studies on how a well-planned ketogenic diet has helped countless people to lose weight and improved their overall health condition by improving their health markers. Another important reason for losing weight on the ketogenic diet is – thermodynamics! When you are practicing the keto diet, you are getting rid of one major macronutrient – carbohydrates! The following list includes the food items that are rich in carbohydrates.
– Fruit smoothies
– Sugar candies
– White rice
These foods have a high caloric value, and when you overeat, these carbs are stored in your body as fat. When you restrict or eliminate these carb-rich foods, you consume fewer calories. When you burn more calories than you consume, you lose weight. This is one main reason that most calorie-restricted diets result in weight loss when done right regardless of the proportion of food you consume. On this type of diet, you are not concentrating on the body composition, food quality or muscle synthesis but it is more to do with the amount of food consumption (smaller portions of food). When your body gets adapted to the keto routine, you feel satiated with fewer calories, which ultimately results in quicker and easier weight loss. But remember, if you overeat on a keto diet, you will definitely gain more weight. So do not expect to lose weight after eating 6000 calories of bacon, beef and butter regularly! You should know how to eat healthy!
