In its origins, the keto diet was created to control cases of epilepsy. Today, it is considered as a method to lose weight quickly and is associated with other benefits.

The ketogenic diet works because reducing carbohydrates lowers blood glucose levels to a minimum. When this happens, body fat is transformed into ketone bodies. A substitute for carbohydrates that the body can use to fulfill vital functions.

In other words, by doing the ketogenic diet, the different types of body fat can be used as an energy source.

Furthermore, the ketogenic diet is used by nutritionists as a treatment for severely overweight and obese people and even diabetics.

  • Lose weight quickly

Basic rules on a ketogenic diet menu

If you have trouble finding the ingredients to make the menu, you can make your own by knowing the main keto rules. The basic rule of thumb on the keto diet is to control your macros. Increase the consumption of fats, consume protein in moderate amounts and carbohydrates are limited to the maximum.

To enter ketosis , on the keto diet the amount of carbohydrates on the menu is reduced to about 0.2 – 0.6 g per kilo of body weight per day. The equivalent of about 20 – 50 grams of carbohydrates per day. (4)

The percentage of macronutrients or macros in the ketogenic diet is (1):

  • 75-80% fat
  • 10-15% protein
  • 5-10% carbohydrates

If you don’t know how to count macros, you can check an example in – how to count macros . Or if it is more convenient for you to download an application for your mobile.

Studies have made it clear that one of the effects of the ketogenic diet is losing weight fast. So some doctors and nutritionists use it in cases of overweight and obesity. (5,8,10)

The effects of the ketogenic diet compared to a traditional low calorie diet are better in terms of time.

The bad news, when you go on the keto diet, you can get side effects. (1.8)

There is no question that the keto diet is one of the most effective weight loss diets in the short term. However, it can have consequences if it is prolonged for long periods of time or taken as a lifestyle.

Ideally, therefore, the ketogenic diet should always be planned by a health professional, and a keto diet menu should be carried out by a physician or nutritionist.

Ketogenic diet – side effects and contraindications

The ketogenic diet has potential side effects and contraindications, especially if it is not done correctly.

Studies have confirmed a deterioration of the nervous system when following a keto diet for periods longer than 12 months. In particular, the power of attention decreases, the speed of memory and the processing of visual information can be affected. (2,3,4)

In addition, fruits, vegetables and cereals are the natural foods with the highest content of vitamins and minerals. When doing the ketogenic diet the lack of iron, calcium and potassium is frequent.

The risk of ketogenic diet side effects in children and adolescents increases as their bodies are in a period of physical growth. In addition, when entering ketosis, adverse effects related to dehydration may appear. The side effects of the ketogenic diet are:

  • Digestive problems
  • Hypoglycemia
  • Dehydration
  • Bad breath
  • Fatigue
  • Irritability
  • Lack of vitamins and minerals
  • Constipation
  • Sleep disorders
  • Lower physical growth in adolescents

The ketogenic diet – keto is contraindicated for pregnant women. Just as it is not allowed for diabetics with uncontrolled blood glucose levels.

It is also not recommended for those who have digestive problems, stomach ulcers or gastritis. Lack of fiber foods on the keto diet can slow down the digestion process and aggravate symptoms.

Ketogenic Diet and Cancer – Should Red Meats Be Avoided?

Recent research claims that the ketogenic diet has a limiting effect on tumor growth, protects healthy cells from chemotherapy or radiation damage, accelerates chemotherapy toxicity to cancer cells, and reduces inflammation (11,12).

The effects of the keto diet against different types of cancer can be seen in the following image:

Therefore some doctors still use the keto diet as an adjunct to cancer treatment. However, this is not as black and white as previously thought.

If meat consumption is high on a keto diet menu, this can be counterproductive in the long run.

The World Health Organization has classified processed meat products: sausages, cold cuts, salami; as type 1 carcinogens. In other words, they increase your chance of getting cancer. (7)

In summary, the ketogenic diet has potential effects to be used as a treatment for certain types of cancer. However, it is recommended that red meat is not the main ingredient on a keto diet menu.

Vegetarian or Vegan Ketogenic Diet – Yes or No?

Going on a vegetarian ketogenic diet is possible. However, by rejecting animal-derived products, the ingredients are limited. Doing the vegetarian or low-meat version of the keto diet is considered healthier for your health.

On a vegetarian ketogenic diet, packaged and processed foods would be off the menu. This is the basis of what is known as clean keto .

As for the vegan ketogenic diet , it is a variant of keto that is not recommended if you do not have a high knowledge of nutrition. The risk of a lack of vitamins and minerals is very high. Ketogenic foods would be basically summarized to nuts, tomatoes, mushrooms and green foods .

Combining ketogenic diet and intermittent fasting is possible. In fact, they are two methods with very similar effects. Reaching the state of ketosis is possible through fasting or going on a keto diet.

However, for most people combining the keto diet with intermittent fasting is not really necessary. It has been proven that if carbohydrates are gradually decreased on a keto diet menu, there are fewer side effects with the same effectiveness. (2)

If you also opt for a type of fast, you can start with the egg fast or egg-fast .

Cyclical keto diet A method for athletes?

The cyclical keto diet is a variant of the ketogenic diet for athletes. As the word indicates, it is done in the form of cycles.

This method is based on the principles of the traditional ketogenic diet, but alternating carbohydrate consumption throughout the week. This is a way to toggle between mode – build muscle tissue and burn fat.

This type of keto diet is used by trainers of high-performance athletes to shed body fat .

On a cyclical ketogenic diet, you alternate between a typical keto diet menu and a carbohydrate diet as your main source of energy by following the steps below:

  • Monday to Thursday nights – strict menu keto diet. Low intensity physical activity – cardio
