What is Keto Diet?
From an earlier age of scientific era (when Greeks ruled and their theories were at the highest level of popularity and authenticity) to 19th century, it was understood that high-carbs and low-fat diets are good for the body. As the 19th-century starts, scientific experiences and practices bring a revolution in medical science. Theories that were coming from the Greek era now started transforming into modern Western philosophy. The theory of low-fat and high-carb diet also changed in 1928.
It was the first time in human history when high-fats and low-carbohydrate diet used for the treatment of epilepsy in children. This high-in-fat and low-in-carbohydrate diet is called the Keto diet. It gained more attention in 1970 when nutritionists, health experts, and health-conscious communities found it a successful potential weight-loss Program.
Atkins, South Beach, Dukan and Paleo diets (high-in-protein, low-in-carbohydrates, and moderate-in-fats) are also popular but all they are high-in-protein. The Keto diet is slightly different from them. It is high-in-fats, moderate-in-protein, and low-in-carbohydrates.
How Ketones formed in the body?
Usually, our body burns carbohydrates into glucose and use it as an energy source. We get the intake of carbohydrates in our bodies through our daily diet we eat. But when we use a Keto diet, it changes this situation.
A Keto diet means “low-carbs, moderate-in-protein, and high-fats” diet. So when we put our body on the Keto diet, the quantity of carbohydrates reduces in our body. Consequently, the production of glucose (an energy source for the body) in the body decreases.
At this stage, the body search for an alternative source of energy. This is the time when fats come in. Carbohydrates are absent from the body and the body must need an energy source. The liver starts to break down the fats into fatty acids. Fatty acids are further converted into molecules called Ketones. These ketones are used by the body as an energy source. This whole process is called Ketosis.
The fatty acids are converted into three types of Ketones.
When Ketones are formed, two Acetyl-Coenzymes (Acetyl-CoA: a molecule used by the body for energy production via citric acid) are joined to make ketones called “Acetoacetate”. The molecular formula is C4H5O3.
Beta-Hydroxybutyrate is the most abundant Keto of three Ketones that accounts for almost 80% of total ketones in the blood. The molecular formula is C4H8O3.
Acetone is the smallest and simplest Keto. It is volatile and colorless. When the body enters is the state of ketosis, it naturally burns in our body. The molecular formula is C3H6O.
How does Keto Diet work?
The Keto diet means a diet that low-in-carbohydrates, moderate-in-protein, and high-in-fats. Before Keto, the diet we intake contains high-carbs and low-fats. In the non-Keto diet, the body burns carbohydrates into glucose and use it as a fuel.
When we apply the Keto diet, it put the body into a metabolic state called ketosis. In ketosis, the diet we intake consists of high-in-fats and low-in-carbohydrates. When the intake of carbohydrates decreases, the quantity of glucose automatically falls down, and the resultant body looks for an alternative source of energy.
Now the body burns the fats into fatty acids and fatty acids into Ketones. These ketones act as energy sources for the body in the absence of carbohydrates. When fat burns, the bodyweight starts decreasing. But when we started the intake of Keto diet (low-in-carbohydrate), the quantity of carbohydrates decreased in the body. Now the body starts the process of fats burning, which automatically leads to weight loss.
Health Benefits of Keto Diet
In the earlier stage, the Keto diet was only used as a treatment therapy of epilepsy in children. But with the passage of time, numerous other health benefits of Keto diet were noted by nutritionists and health-conscious community. The major health benefits of Keto diets are as follows.
Keto diet, due to low carbohydrates, reduces intake of calorie which leads to a decrease in appetite or hunger.
Keto diet is a short-term and speedy weight loss diet. Because in Ketosis state, the body burns fats which automatically reduces body weight.
Lower the Triglycerides
Triglycerides are fat molecules that increase heart diseases. The Keto diet is every effective to lower the triglycerides in our body.
Boosts Brain Functioning
When the body puts in metabolic states, the growth of the brain’s cell improves. Thus it increases the functioning of brain-like increased in clarity, cognition, and memory, etc.
Increase Good HDL Cholesterol
As Keto diet is high-in-fats, that’s why it increases the level of HDL cholesterol which is good for us.
Lower the LDL Cholesterol
Keto diet reduces the level of LDL Cholesterol which is usually called bad cholesterol for the body.
Decrease Blood Sugar and Insulin level
Keto diet reduces the carbohydrate consumption in the body which is the best way to lower the level of blood sugar and insulin.
Lower the Blood Pressure Level
Lower level of carbohydrates is the most effective way to lower the blood pressure level. The lower level of blood pressure reduces the risk of various common diseases.
Removes symptoms of Metabolic Syndrome
Metabolic Syndromes are the symptoms of five serious conditions that increase the risk of type 2 diabetes and heart diseases. Those five serious metabolic syndromes are the following.
- The elevated level of fasting blood sugar.
- Abdominal obesity.
- High triglycerides.
- High blood pressure.
- Low level of good HDL cholesterol.
A low-carb and high-fat diet like Keto diet is extremely effective to remove the metabolic syndromes / above mentioned five symptoms.
Beneficial in Several Brain Disorders
A diet that is low-in-carbohydrates i.e. Keto diet, is very beneficial and is therapeutic in various brain disorders like epilepsy in children.
Diminishes the Depression and Anxiety
Keto diet burns the fats from your body that ultimately leads to losing weight. This situation executes you from depression and anxiety.
Protection against Type-2 diabetes
From several experiments and observations, nutritionists declared Keto diet a successful protection against type-2 diabetes.
Helpful in Treatment of Cancer
Cancer cells have several insulin receptors. The Keto diet lowers the level of blood sugar and insulin in the body which reduces the risk of cancer and improves in the treatment of cancer.
Boost up the Heart health
When the Keto diet burns the fats, it is a good sign of health. Thus it prevents from various heart diseases in metabolic state.
Keto diet is profoundly anti-inflammatory is very helpful to decrease inflammation in our body. Inflammation leads to arthritis, psoriasis, pain, acne, IBS and eczema, etc.
