As described in the title this is the complete and comprehensive guide to keto diet including introduction, best drinks, fruits, things to avoid and health benefits. Let’s continue with its introduction.


A high-fat diet with adequate-protein and low-carbohydrates is known as Ketogenic or simply a keto diet. The name keto is given to this diet because it allows the body to produce ketones which are small fuel molecules. These fuel molecules act as the alternative energy source instead of sugars. It offers many health benefits against harmful diseases such as diabetes, cancer, epilepsy and Alzheimer’s and also helps in weight loss because Keto diet can help you burn fat more effectively.

Keto diet helps in reducing carbohydrates intake in the body by replacing it with the fats. These fats get turns into ketones in the liver, which can act as an energy source for the brain.  As the keto diet is low-carb and high-fat so, it lowers blood sugar level and shifts the body’s metabolism towards the fats and proteins.

Types of Keto Diet

There are several versions of ketogenic diets but four are major types. Below is a brief introduction to each type.

  • Standard ketogenic diet (SKD)

It is termed as a standard ketogenic diet because it exactly follows the definition of the keto diet, as it is a high-fat diet with very-low-carb and moderate protein levels.

According to grams per day, the standard ketogenic diet may contain:

  • 20-50gm of carbohydrates
  • 40-60gm of proteins
  • No set limit for fats
  • Targeted ketogenic diet (TKD)

The Targeted ketogenic diet is similar to an SKD except that carbohydrates are consumed around exercise times. Any day you exercise, you are allowed to take  a high amount of carbohydrates in the keto diet.

  • Cyclical ketogenic diet (CKD)

It is also known as carbohydrates backloading because it involves days of higher carbohydrates that refeed the carb, such as 2 days of higher carbohydrates in a week. 

  • High-protein ketogenic diet (HPKD)

As the name is indicating that this diet includes more protein as compared to the standard ketogenic diet. The percentage of different compounds is as follows :

  • 35% of Proteins
  • 60% of fats
  • 5%  of Carbohydrates

  • The rise in energy levels

Keto diets contain high-fats which contain double the amount of energy as compared to an equal number of carbohydrates. In the beginning, your body should change the energy cycle and When you get into ketosis, the brain starts burning ketones instead of glucose. So, fats become the ultimate source of energy for the body.

  • Diminish anxiety and depression

Keto diet is also known as an anti-anxiety diet as it helps reduce anxiety, depression, and fear. The reason behind this reduction in anxiety is Ketone Supplements. According to recent studies, beta-hydroxybutyrate (a ketone) may help reduce stress-related disorders like anxiety by diminishing brain inflammation

  • The liver gets healthier

The ketogenic diet may improve liver health, as it shifts the energy cycle towards fats. Actually, this ketosis cycle occurs inside the liver and the accumulated fats in the liver are transformed into ketones which help in protection against type 2 diabetes.

  • Proper Sleep Cycle

When the energy level of the body rises, the body feels relax and that is the reason people on a ketogenic diet sleep much deeper. Proper sleep help in optimizing our hormones.

  • Boost heart health

In the ketogenic diet, fats from the food and from the body are transformed into ketones, so the blood cholesterol level decreases to a great extent. Moreover, losing weight can help reduce cardiovascular risk factors and helps reduce high blood pressure and arteries diseases.


To conclude, it is now obvious that high-fats and low-carb can help reduce many risk factors for health including anxiety, depression, bad cholesterol, high blood pressure and low level of energy.

What to eat on a Keto Diet?

The keto diet is a very low-carb, moderate protein and higher-fat diet. While you take a small number of carbohydrates on a keto diet, you maintain moderate levels of protein and fulfill your energy needs by increasing your fat intake. The increase in fat and the reduction in carb intake puts your body in a metabolic state called ketosis. In ketosis, fat from your diet and from your body is turned into small fuel molecules called ketones, which are burned to release energy.

Why we need ketones to fulfil the brain’s energy needs? 

On a ketogenic diet, your entire body switches its energy supply to run mostly on fat but the brain can’t run on fat directly, it can only utilize glucose – or ketones. So, in the liver fats are breakdown into small ketones. These ketones are directly used by the brain for energy.
