Keto Flu Symptoms and What Causes Them

Keto dieters are fully aware of the keto flu symptoms which can feel exactly like the real flu. Despite the fact that it isn’t very dangerous or life-threatening, keto flu can make many people feel really awful. Some of them can’t handle it, so they decide to put an end to their keto diet journey.

However, all of our metabolisms handle things differently, so the keto flu symptoms and the severity of each affect every person a little bit differently.

What Can Cause The Keto Flu Symptoms?

Even though experiencing keto flu symptoms during a weight loss journey is far from ideal, many keto dieters believe that it’s actually the key indicator that they are on their way to the state of ketosis. Medical experts can’t explain what causes these symptoms, but there are some theories behind them, such as:

  • Relative Hypoglycemia
  • Carbohydrate Withdrawal
  • Hormone Imbalance
  • Electrolyte Imbalance and Dehydration

As we mentioned before, all keto dieters can experience these symptoms due to one or more of the following factors.

Low Blood Sugar

Dietary carbs can quickly break down in your body to glucose. On a regular basis, your body uses energy from the stored glucose through the glycolysis process.

However, when you ditch the carbs and start eating more fats. Your body is forced to use fat for energy through the beta-oxidation process and start producing ketone bodies.

It’s not as easy as it may sound and your body will need some time to start using fat for energy. During this transition phase, your blood glucose can get lower than your body is used to.

This condition is hypoglycemia and it can cause some of the keto flu symptoms described by the keto flu.

This condition can be dangerous for people who suffer from diabetes.

Carbohydrate Withdrawal

When you switch from a high-carb diet to no carbs can be quite shocking to your body. This can feel either better or worse to your system and it depends on your carb intake before going keto.

Many people may experience the same process of, craving, binging, withdrawal, and sugar dependence. Like other forms of addiction, just like alcohol or drugs.

The same part of the brain will light up to any addiction, it can’t recognize whether it is drug addiction or carb addiction. Neurotransmitters release dopamine when people are eating carbs.

Most common symptoms of drug withdrawals usually involve mood swings, headaches, nausea, irritability, difficulty concentrating, etc. Some people think that keto flu is just the body’s response to carbs withdrawal.

Keto Flu Symptoms – Hormone Imbalance

Some people believe that carb restriction can temporarily alter thyroid hormones. Lower levels of T3 – an active thyroid hormone – can lead to many symptoms such as mood changes, fatigue, and constipation. There isn’t any evidence that can prove low carbohydrate intake is linked to subclinical hypothyroidism.

4. Electrolyte Abnormalities & Dehydration

Insulin is а hormone made in the pancreas and is in charge of storing glucose. In order to maintain healthy glucose levels, insulin increases when you consume carbs and maintains lower levels while fasting. When you don’t consume carbohydrates, insulin doesn’t increase as much as after eating because there isn’t much glucose to store.

Lower levels of insulin can have an impact on the absorption and availability of water and even make changes in electrolytes in your body and dehydration. During ketosis, keto dieters might experience diuresis – a process where you lose water and sodium. Even though this isn’t dangerous, it can make you feel bad while you are on your keto journey.
