When starting out on the ketogenic diet, you are naturally looking for the benefits of it. But you will feel bad after a few days. You will feel tired, suffer from headaches, and may have difficulty concentrating.
Symptoms of keto flu vary from person to person. Some people may feel uncomfortable or tired for a day or two since the start of the diet. While others may experience symptoms that severely affect the ability to function for several days.
These unpleasant symptoms of the ketogenic diet are called the keto flu. But it is not real flu, and it is not contagious.
What is Keto Flu?
Some people follow different diets to help them lose excess body weight. Among the well-known systems is the “keto diet”, which is based on a diet that is low in carbohydrates and rich in protein and vegetables.
But like all systems, the keto diet produces side effects, including what is known as the keto flu, and its symptoms are similar to those of influenza.
Keto Flu Symptoms
Symptoms of keto flu include:
- Feeling nauseous
- Feeling dizzy
- An overwhelming desire to eat sweets
- Lack of activity
- Difficulty concentrating
- Muscle spasm
The main reason behind the keto flu is that the body shifts its dependence from burning sugar to burning fats for energy.
The ketogenic diet’s work mechanism consists of switching from a high-carb diet to a free/low-carb diet. This is what leads to a decrease in insulin in the body.
And when insulin levels are low, that is a signal for the liver to work to convert fats into ketones that most of the body’s cells can use in place of glucose.
When the body uses ketones and fats for energy, it enters a state called ketosis.
However, it takes time for the body to get used to the new energy source. When insulin is low, the body responds by excreting more sodium in the urine as well as water.
In this case, you will need to urinate more than usual during the week or in the first days on the keto diet.
This change in the body is responsible for the rapid results that happen, which are great results. These results include the weight loss that occurs in the early stages of the ketogenic diet.
When to see a doctor?
Before starting the keto diet, or if you are already on the keto diet and notice any of the listed symptoms, you should consult a health professional as soon as possible.
