Can Intermittent Fasting Ruin Your Metabolism?

Did you know that fasting can harm your metabolism? Fasting is an excellent method to lose weight, but like all things with a side effect, intermittent has its own drawbacks too.

We have researched this subject matter and want to enlighten people through this article.

What is fasting

Fasting is deliberately choosing to eat little or nothing at all for an extended period. The interval for eating in fasting varies, and it is done for differing reasons. Fasting has existed thousands of years ago and is done by our forebears. 

People fast, due to religion, protest, special occasions, traditions, and more. However, in the 20th to 21st century, a new trend begins to emerge. It is fasting to lose weight. After world war 2, perhaps, because things were more relaxed, there was a tremendous increase in man’s average weight, especially in the US.

The US government and individuals start researching on losing weight for a  healthy lifestyle. Among their best discoveries is fasting. Going without food for an extended period helps the body to lose weight faster.

What is metabolism

Metabolism is the series of chemical reactions that transforms food into energy for the body. This process is very significant when it comes to how fasting causes weight loss. It is metabolism that undergoes some changes when fasting to make the body lose weight fast and effectively.

Can it ruin metabolism?

This is a situation of overdoing something. Yes, fasting is good and has health and mental benefits for man. However, when overdone, it can also bring side effects. The body’s metabolism needs the ‘normal’ dose of calories to keep it working. It is just like hormones, which have a trigger. Metabolism triggers steady and average calories.

However, taking a break and fasting for some time will not hurt the metabolism. However, when this is overdone, the metabolism might start slowing down. If the metabolism starts slowing down, it is equivalent to the weight loss, slowing down, which leads to obesity. It is a chain of reactions that is understandable.

Metabolism slows down as a result of the body going into a model known as ‘starvation mode’. Because the body understands there is no food, it starts slowing down the rate at which it burns calories. This is to prevent running out of storage, which will eventually lead to death. With this as a result of intermittent fasting, then it needs to be regulated. To find a time that is just okay and in between—not too long or short.

Types of fasting

There are different types of fasting with various rules. They are all compelling; it is up to an individual to choose which one is preferable to him/her.

16:8 intermittent fasting:

For  16:8, there is an 8-10hrs window for eating. That is, within 24hrs you have 8-10hrs to eat anything you wish till the time elapses. As a result of this, after the 8hrs grace is gone, you cannot take any other food for 14-16hrs until 24hrs is used up.

The 8-10 hrs is most of the time between 11 am to 7 am. Once this time has expired, you cannot retake any food if you are using this fasting method.

5:2 fasting:

Two days of the week are selected in 5:2 for fasting. Only 25 percent of the required daily calories —500 for women and 600 men is ingested taken during these two days. However you are, you can resume your regular diet in the subsequent days, which is the remaining 5days.

The fast day is supposed to be two consecutive days; however, when one non-fasting day divides, it becomes 4:3. Some people, however, make it 4:3, where a fast day is alternated with a no short day.

Prerequisites of fasting

To be sure you are in proper shape physically and mentally to go through fasting, some preparations have to be made.

1. Must possess a good diet

The foods you take and the nutrients they supply you play an essential role in inviting your daily activities. It would help if you took a balanced diet in the month and days preceding your fast to ensure you are in good health.

2. Must have a healthy daily routine.

Before undergoing a fast, you must be physically and mentally fit. These are things that can only be with healthy lifestyle choices. You have to get enough sleep, drink enough water, and proper exposure to the sun; these are the basic guidelines to a healthy life.

Why is intermittent fasting good for you?

Although, when overdone intermittent fasting can cause the metabolism to slow down. However, when done well, fasting has a good effect on the body,  No 1  of which is weight loss.

●     It helps to lower the risk for diabetes type 2:

The high Blood sugar level in the context of diabetes type 2 is what causes diabetes.The rate at which diabetes is prevalent now is due to the increased consumption of people. Fasting helps to lower insulin resistance and reduce the auger level in the body, thereby preventing diabetes.

●     It helps protect the heart

Heart disease is so prevalent now, and many have it. Fasting has been shown to increase the risk factors of heart disease—which is a good thing. However, this study is based on animal experiments; it has not been thoroughly researched on human beings.

Intermittent fasting verdict

Although intermittent fasting is very effective in aiding weight loss however it is not for everyone. You do not have to feel bad if you can not endure going without food for an extended period, you will eventually find a way that works for you.


Intermittent fasting is a method of losing weight by restricting food intake for some time. However, if done for too long might hurt the metabolism and affect its performance. 16:8 and 5:2 are two popular types of fasting; they are practical and do not hurt the metabolism.

There are also some prerequisites of fasting, which is that you must follow a proper and healthy lifestyle to ensure your body is in a fit state to endure fasting.
