While intermittent fasting does work, there are some side effects you should be aware of before trying it. If you’re going to try this out for yourself, there are things you need to know first.

If you’re considering trying intermittent fasting, you may be wondering what the side effects might be. This popular weight loss method has been shown to have some health benefits, but there are also some potential downsides. Here’s what you need to know about the potential side effects of intermittent fasting.

Check out Intermittent Fasting 20/4 VS 16/8.

Very low blood sugar level

There are two main types of intermittent fasting. The first is from 12 to 16 hours, and the second is from 21 to 26 hours. In both of these cases, the body goes into a catabolic state.

What does this mean? Well, your body is going to burn more calories than normal, so you’re burning fat for fuel. But, fasting for longer than 16 hours can take its toll on your health.

After about 24 hours of fasting, your body stops releasing insulin completely, so you’re going to have an extremely low level of glucose in your blood. With this, you can end up having a heart attack or stroke.

Mood swings

Another concern is the moodiness. Intermittent fasting can lead to binge eating because your blood sugar is so low.

You could also have an unpleasant experience with your mood. Your body uses carbs as fuel, and when they aren’t available, it will start going to fat. While intermittent fasting can do wonders for your body, it can also cause your body to use muscle tissue as fuel.

Lose muscle mass

Once you’ve gone without food for a couple of days, your body will start going to fat and muscle to use it as fuel. So, you lose muscle mass, which is actually a very serious issue.

So, you should be careful with intermittent fasting. First, you should consult your doctor and see if it’s right for you. If not, then you should ask what is the best alternative.

Intermittent fasting isn’t for everyone, and it’s not a good idea if you have any underlying health issues. And, in order to prevent muscle loss, you’ll need to ensure that you eat enough protein and vegetables when you are able to eat.

Loss of appetite

One potential side effect of intermittent fasting is that it can lead to a decrease in appetite. This may result in weight loss if you’re already trying to lose weight, but it can also be dangerous if you have an eating disorder or are not physically active.


One of the most common complaints among those who practice intermittent fasting is hunger.

This is because when you’re fasting, your body isn’t getting the regular influx of nutrients it’s used to. As a result, you may feel hungrier than usual, especially in the early stages of intermittent fasting.

There are a few ways to combat this hunger, such as drinking plenty of water and eating high-protein foods. However, if the hunger becomes too much to bear, it may be best to discontinue intermittent fasting.

Brain fog

Intermittent fasting is a popular dieting trend, but some people report feeling “foggy” or “out of it” while fasting. This feeling is most common during the first few days of fasting, but can also occur at other times.

The cause of brain fog during intermittent fasting is not fully understood, but it is thought to be related to low blood sugar levels.

Brain fog usually goes away after a few days of fasting, but some people may experience it off and on throughout their fasting journey. If brain fog is a persistent problem, it is important to talk to a doctor or dietitian to make sure that intermittent fasting is safe and right for you.


Intermittent fasting is a popular dieting trend, but it can have some unpleasant side effects, including constipation. When you don’t eat for long periods of time, your digestive system slows down and you may become constipated. If you’re experiencing constipation while intermittent fasting, there are a few things you can do to ease the symptoms.

  • First, make sure you’re drinking plenty of fluids. This will help keep your digestive system moving.
  • You can also try eating high-fiber foods or taking a fiber supplement.
  • Finally, if you’re still having trouble, you can talk to your doctor about other options, such as laxatives.

Hair loss

Some people have reported experiencing side effects like hair loss.

While it’s not clear exactly how intermittent fasting can cause hair loss, it is thought that the stress of fasting can cause hair follicles to enter a resting phase. This can lead to shedding and, eventually, hair loss.

If you’re concerned about hair loss, it’s important to talk to your doctor before starting any new diet. They can help you determine if intermittent fasting is a safe and effective way to lose weight.

Nutritional deficiency

There is some concern that intermittent fasting may lead to nutritional deficiencies.

While fasting, the body is unable to absorb nutrients from food, which can lead to a lack of essential vitamins and minerals.

Also, you may not focus on getting all nutrients your body want on the eating period.

So, make sure you are following a balanced healthy diet along with fasting.


Additionally, people who fast are at risk of dehydration, as they are not consuming any fluids. but it can have some serious side effects, including dehydration. When you’re not eating, your body isn’t taking in any fluids, and over time, this can lead to dehydration. Symptoms of dehydration include:

  • dark urine.
  • fatigue.
  • headache.
  • dizziness.

If you’re thinking about intermittent fasting, be sure to drink plenty of fluids and monitor your hydration levels closely.

Weakness and tiredness

One of the most common complaints among those who practice intermittent fasting is weakness and fatigue. This is usually due to the fact that when you’re not eating, your body isn’t getting the energy it needs to function properly.

If you’re feeling weak and tired while intermittent fasting, it’s important to make sure that you’re drinking plenty of fluids and getting enough rest.

You may also want to consider adding a few extra calories to your diet on days when you’re fasting, to make sure that your body has enough energy to get through the day.

The intermittent Fasting benefits

There are a lot of benefits to intermittent fasting, but it’s not the best option for everyone. You should always start with a gradual approach and see how your body responds to it.

Weight loss

Intermittent Fasting may be as Effective for Weight Loss as Cutting 500 Calories a Day, as some researches Suggest.

According to research, intermittent fasting may help you lose weight just as effectively as cutting 500 calories a day. Intermittent fasting means you only eat between a certain time frame, and you fast every other day.

Regulate metabolism

Eating every three hours is often recommended as it allows your body to regulate the metabolism at a regular rate.

Researchers at the University of Barcelona in Spain studied 23 obese participants and compared their results with those of a group of 21 normal-weight people.

After a month, both groups lost a similar amount of weight and body fat.

However, while the normal-weight people maintained their body mass index, the participants in the obese group, who followed the intermittent fasting method, had an improved “insulin sensitivity, ” meaning they were less resistant to insulin .

This metabolic benefit has led some people to use intermittent fasting as a method for weight loss.

While intermittent fasting may improve insulin sensitivity, some studies do not recommend it for those with type 2 diabetes. In people with diabetes, insulin resistance is a greater issue than insulin-receptor deficiency.

Improve health markers

In the short term, intermittent fasting can improve certain markers of health like:

  • Lower risk of heart disease.
  • Cancer markers.
  • Decrease cholesterol levels.
