What is Intermittent fasting?
Intermittent fasting is nothing but just an eating pattern where you only eat during a particular period. It is more about when to eat as compared to what to eat. A person has to do fasting every day for a specific number of hours. Also, they are allowed to have one meal for a couple of days or a week. It helps to burn your body fat.
What happens in Intermittent fasting?
Basically, in intermittent fasting, a person eats in a particular time window, like within 8 to 10 hours.
If you are fasting and not eating food, your insulin level in the body will decrease. The dropped level of insulin induces cells to release stored glucose as energy. Your body starts using fat collected in your cells for energy. And guess what? You start burning fat instead of storing it. And it leads to weight loss.
How Intermittent Fasting Affects Your body?
Intermittent fasting affects the body in different ways and provides several benefits along with weight loss. Let's check them out.
1. Effect on the functionality of hormone, gene, and cells
The human body is a complex system. Even if you are missing a single meal in a day, many things happen in the body. When you don't eat food, the level of hormones changes in the body. It happens so stored body fat is more accessible as energy and starts effective cellular repair processes.
Intermittent fasting makes changes in the following:
- Insulin level drop-down while fasting.
- The blood levels of human growth hormones may rise. The high level of HGH helps in fat burning and muscle gain.
- During fasting, the body starts crucial cellular repair processes.
- Various advantageous changes start occurring in several genes and molecules. It enhances life span and safeguards against disease.
2. Effect on body weight
Most people begin intermittent fasting to lose weight. In intermittent fasting, you will eat fewer meals at a particular time. Due to this, you will take fewer calories. Not only this, but it also enhances the hormone functionalities, and it results in weight loss.
When the insulin levels decrease, HGH levels increase, then the body starts using the fat stored in the cells for energy.
One scientific study shows three to eight percent weight loss within 3 to 24 weeks when a person is on intermittent fasting. Also, the person lost 4–7% of their waist circumference within 6–24 weeks.
Intermittent fasting has the potential to be a potent weight-loss tool. Do you want to give it a try?
- Effect on Blood Pressure
Intermittent fasting can help to lower blood pressure. If you have the issue of high blood pressure, then you can try intermittent fasting. It is essential to keep your blood pressure in a normal range. Otherwise, it can lead to kidney disease and heart disease.
As per research, you can only lower your blood pressure while practicing intermittent fasting. Once you stop it, your blood pressure will get back to its earlier range. So it's your choice if you want to practice intermittent fasting for the long term or not.

The things that are good for your body are always good for your brain also. Intermittent fasting helps to reduce oxidative stress, blood sugar levels, insulin resistance, and inflammation.
Intermittent fasting increases the level of BDNF (brain hormone). Brain hormone deficiency results in depression and various other brain-related problems.
When various studies were performed on animals, it showed an improvement in the growth of new nerve cells. And it is beneficial for brain function. It also guards against brain injury that occurs due to strokes.
Effect on Overall Health
Intermittent fasting helps to maintain overall health. It may help to prevent cancer and Alzheimer's diseases.
As per animal studies, fasting can guard against various neurodegenerative diseases, including Parkinson's and Huntington's. We require research on humans also.
Intermittent fasting similarly increases lifespan as perpetual calorie restriction. To check this lifespan theory, scientists study it on mice. Mice were fasted every other day to check their lifespans. And guess what? It increases up to 13%. Daily fasting has been shown to improve the overall health of male mice.
So this was all about intermittent fasting. Whether you want to lose weight or looking for health benefits, intermittent fasting can help you.
