What is the ketogenic diet and what are its benefits and side effects? What should we eat and what should we not eat in this diet? Keto diet has different types, but the main source of your nutrition in all of them is protein and fat. Ketogenic has become very popular these days. Many people claim that they have succeeded in losing a lot of weight and reaching their goals with this diet.
In this article, we are going to fully introduce the ketogenic diet and tell about its benefits and side effects, and also give a sample diet for it.
What is the ketogenic diet?
The ketogenic diet, often referred to as the keto diet, is an eating plan in which fat and protein are abundant and carbohydrates are very, very low (or even completely eliminated). The goal of the ketogenic diet is to replace carbohydrates with fat and burn fat. Simply put, you force your body to use fat instead of carbohydrates for energy.
There are different versions of this diet, but the most researched version is the “standard keto diet” and we will review this standard diet in this article.
It is interesting to know that this diet was originally used to treat drug-resistant epilepsy, but it became very popular and widespread when people realized that it could help them lose weight!
How does the ketogenic diet work on the body?
Normally, when you eat carbohydrates every day, your body turns to these carbohydrates for energy. But when the intake of carbohydrates is cut off, the body must go to another source of energy, namely fat, and this means consuming fat and burning fat!
The whole way the keto diet works is to force your body to use a different type of fuel. Instead of relying on sugar (glucose) from carbohydrates (such as wheat, barley, rice, beans), the body must turn to ketones, a type of fuel produced from stored fat. This state is called ketosis.
Entering ketosis requires depriving yourself of carbohydrates, that is, consuming less than 20 to 50 grams of carbohydrates per day. Keep in mind that an average banana has about 27 grams of carbs or an average baked potato has 41 grams of carbs, so the ketogenic diet is tough and requires careful planning.
How does completely eliminating carbohydrates affect weight loss?
Extensive research has been done on the relationship between carbohydrate elimination and weight loss, and all studies unanimously confirm the effect of carbohydrate elimination on weight loss. But how cutting out carbs causes weight loss has a few different reasons.
Normally, when you eat carbohydrates, a lot of glucose enters the bloodstream and the blood sugar level rises. But when carbs are cut, blood insulin levels drop, and your body gets the signal to burn stored fat for energy instead of storing fat. In other words, the lower and lower the glucose, the more the body is forced to burn fat.
Also, in the first few days when you have restricted and eliminated carbohydrates, you will also lose a lot of water, and as a result, you will experience a rapid weight loss.
But that’s not all. By consuming more protein, you will feel fuller for longer. In addition, the keto diet can affect appetite-regulating hormones such as leptin and ghrelin and reduce the secretion of these hormones. Finally, when you restrict carbohydrates, you often naturally reduce your caloric intake as well.
Health benefits of the ketogenic diet
What are the benefits of the ketogenic diet? In this section, we would like to introduce you to the various advantages and benefits of this food plan.
1. Lose weight without burning muscle
The first benefit of the keto diet is that it makes you slim. But this weight loss is not very difficult, because you don’t feel very hungry, also it is a healthy way to burn fat.
Also, since you are consuming a lot of animal proteins, you can rest assured that your body is not burning muscle, but burning fat.
2. Improvement of facial pimples and acne
Acne has many causes. But one of the most important reasons is the consumption of carbohydrates and blood sugar. When your diet is rich in processed and refined carbohydrates, the balance of gut bacteria changes, and this significant increase and decrease in blood sugar negatively affects skin health. A lot of evidence shows that removing carb acne also gets better.
3. Reducing the risk of some cancers
Researchers have investigated the effects of the ketogenic diet in helping to prevent or even cure some cancers. A reputable 2018 study found that since the ketogenic diet lowers blood sugar, it can also reduce the risk of insulin side effects. Insulin is a hormone that controls blood sugar and may be associated with some cancers.
4. Improves PCOS symptoms
Polycystic ovary syndrome (PCOS) is a common hormonal disorder among women that causes ovulation disorders. Research shows that low-carb diets can improve PCOS symptoms, such as weight loss, hormone balance, and blood sugar control.
Allowed and forbidden foods and fruits in the keto diet
If you are planning to start this diet, we recommend two important points. One is to reduce the consumption of sugar, caffeine and alcohol a few days before starting keto so that it is easier to enter this diet. Second, consult your doctor, especially if you have a specific medical condition. Now we will name the allowed and non-allowed foods in the keto diet.

Types of ketogenic diet
Ketogenic diet is generally a diet that tries to put the body into ketosis by lowering the consumption of carbohydrates. A state in which the body breaks down fat into ketones and uses ketones as an energy source instead of glucose. But still, there are different methods to create a state of ketosis and different types of ketogenic diets have been designed so far. In the following, we will name some of the most famous types of keto diet.
High protein ketogenic diet
This diet contains more protein than the standard ketogenic diet and its ratio is 35% protein, 60% fat and 5% carbohydrates. Research has shown that this diet is more effective for weight loss and muscle retention.
Targeted ketogenic diet
This diet is similar to the standard ketogenic diet, but with the difference that carbohydrates are consumed during exercise. This diet is kind of a middle ground between a standard ketogenic diet and a carb cycling diet that allows you to consume carbs on the days you exercise. In this diet, you can eat carbohydrates before and after the days when you exercise.
Ketogenic diet with calorie restriction
This diet is similar to the standard ketogenic diet, except that calorie intake is restricted. This type of diet is very difficult and sometimes impossible, and there is no need to be so difficult. Because research has shown that all types of ketogenic diets, whether with or without calorie restriction, are successful for weight loss, because the effect of fat saturation and the state of ketosis itself prevents overeating.
Mediterranean ketogenic diet
It is a combination of the ketogenic diet and the Mediterranean diet, which emphasizes the consumption of healthy fats such as olive oil and fish.
Vegetarian ketogenic diet
This diet is designed for people who are vegetarians and includes vegetable sources of fat and protein.
Who is the keto diet suitable for?
Most of those who go for the keto diet are those who want to lose weight. But apart from weight loss, the most important benefit and feature of keto is that it controls blood sugar, so this diet is also suitable for people with insulin resistance.
Keto can also help control and manage certain diseases such as epilepsy. It may also help people with heart disease, some brain diseases, and even acne, but more research is still needed in these areas. Before starting this (and any) diet, talk to your doctor first to find out if it’s safe for you, especially if you have type 1 diabetes.
Does the keto diet have side effects?
