Now, let’s take a look at how it can boost the immune system and thereafter its side effects.

Extreme weight gain and obesity pose serious health risks.

They lower the body’s natural immune response by increasing the risk of several infections.

Clinical reports indicate that those who are obese are likely to suffer from respiratory tract infections.

However, the keto diet can help to reduce the risk of these infections.

It has been shown to be a safe and effective diet plan that helps to reduce obesity.

Its weight loss benefits also make it effective in reducing the development of inflammatory conditions.

If you use the ketogenic diet correctly, then it can help to improve your nutrient intake.

Understand that nutrition is an important part of development. It’s considered a crucial determinant of the immune response.

That’s why if you suffer from a nutrition deficiency, your chances of suffering from infectious diseases are high.

This is because your body’s immune system is weak and, therefore, the immune response won’t be effective.

However, this diet helps to improve immune health by facilitating the absorption of micronutrients.

This usually comes from the whole-foods which the keto lifestyle advocates for.


3. Improving Your Ability to Deal with the Flu

A study done by Yale University in 2019 indicates that keto may be effective in managing flu symptoms.

It was established that a group of mice fed on a keto diet had better chances of dealing with the flu.

In fact, their survival rate was higher compared to those that mostly fed on high-carb diets.

Well, this is because the diet facilitated the release of immune system cells.

As a result, the mice were able to produce more mucus in the cell linings of the lungs

This made it possible for them to effectively trap infectious flu viruses.


4. Promoting Cardiovascular Health

Can keto make you sick

Yes. For some people, the side effects of the keto diet can be severe

Even though it can improve the functions of the immune system, it can also affect it negatively.

So, why does this happen and what are the possible remedies? 


Why Do I Feel So Sick on Keto Diet -Top Five Reasons

1. Nutrient Deficiency

If you are not eating a wide variety of grains, fruits, and vegetables, your risk of deficiency will increase.

Your chances of suffering from diseases such as the common cold will increase.

This is because poor nutrition has a direct impact on the body’s immune system.


2. Less Carb Intake

Why Do I Feel So Sick on Keto Diet carb intake

Most nutrients usually come from carbs.

That’s why if you are on a keto diet, you will easily find yourself craving carbs.

The body needs them to facilitate different processes that will lead to an overall good immune system.

Due to the drastically low amounts of carb intake, your body will end up feeling stressed.

Clinically speaking, taking fewer carbs is a stressor to the body since this is its preferred source of energy.

Once the body is stressed, the immune system is expected to create a healthy balance.

However, the immune system can’t effectively solve such a problem due to the lack of adequate nutrients.

As a result, the dieter’s health will be negatively impacted.

You can refill your carb supply by having “cheat” days where you increase your daily carb intake.


3. Hormonal Imbalance

Why Do I Feel So Sick on Keto Diet hormonal imbalance

One of the reasons why the ketogenic diet can make you feel sick is due to hormonal imbalance.

If you are not eating enough carbs, then the production of certain hormones will reduce.

The human body is trained to use glycogen to produce energy.

If you are going to change this, you will be interfering with several natural processes.

The nutrients you consume daily from carbs play an important role in the functioning of the endocrine system.

Note that the endocrine system is responsible for the release of hormones.

It is also known as the key molecular signaler. So, it hellos to convey certain instructions.

Extreme diet restrictions that come with keto can lead to harmful effects.

The natural hormone production will change. The levels might increase or decrease.


The dieter in this case might end manifesting psychological symptoms.


Keto Interferes with Which Hormones?

Hormonal changes mostly affect women.

The female body has complex nutritional needs and this mostly comes from carbs.

Without enough complex carbs, the production of the following hormones will change:


  • Insulin that’s used for metabolism
  • Progesterone
  • Serotonin.


Low levels of serotonin will lead to high levels of cortisol, the stress hormone.

This can cause weight gain or weight loss.

An imbalance in the level of progesterone will interfere with menstruation.

Some women may miss menstruation.

Dealing with hormonal imbalance while on keto can be quite tricky.

The best way to avoid these unwanted side effects is to make use of the “cheat” days.

Your body definitely needs carbs for some process and you have to consume them.


4. Elimination of Electrolytes

Why Do I Feel So Sick on Keto Diet - elimination of electrolytes

One of the benefits of a keto diet is to reduce the high levels of insulin.

However, did you know that an extremely low level of insulin is bad for your health?

You might be wondering why you feel sick and your immune response is weak if you are in keto, right?

But the fact that you have low insulin levels due to lack of enough carbs interferes with the presence of electrolytes.

Keto will force the kidneys to excrete important electrolytes such as potassium and sodium.

You will end up feeling sick because electrolytes are beneficial in:


  • Regulating of nerve function
  • Improving muscle function
  • Hydrating the body
  • Facilitating the rebuilding of worn-out and damaged body tissues
  • Helping to effectively balance blood pressure and acidity

To combat the elimination of electrolytes, ensure that you take an adequate amount of salt daily.


5. Poor Memory and Brain Fog

Keto diet directly affects how the brain functions

The brain and the immune system have to communicate for the body to remain healthy.

There are communication pathways that link the two.

This is because the brain helps to regulate immune responses.

The low-carb diet minimizes the supply of glucose to the brain.

This means that it won’t effectively produce energy.

As a result, you will end up experiencing an abnormal fall in the levels of blood sugar.

If that’s the case, it means that your immune system will also be affected.

The result is that you will end up feeling generally weak and sick

To eliminate brain fog, drink lots of water, and increase your salt intake.

It’s also important that you avoid strenuous workouts.

The keto diet’s mechanism of working can result in positive and negative effects.

To some people, using keto is the surest way of boosting their immunity.

This is because the low-carb diet helps to regulate several processes in the body.

However, significantly reducing your carb intake can lead to a weak immune system.

This is due to nutrition deficiency that affects other systems in the body.

However, you can deal with the side effects of keto and still use the diet for your wellness needs.
