How Intermittent Fasting Affects Your Body and Brain | The Human Body
Stars like Beyonce and Hugh Jackman have spoken out about following intermittent fasting plans to get in shape. How does intermittent fasting work? Here's what actually happens to your body and brain when you fast. Following is a transcript of the video.
How long has it been since you last ate? People who fast intermittently often eat within an 8-hour block, leaving 16 hours of fasting in between. During that 16-hour stretch, their bodies undergo an important change that sets them apart from non-fasters.
Here's how it works.
When you eat, you store some of that energy in the liver as glycogen. But after 10-12 hours of not eating, your glycogen reserves will be extremely low. As a result, you may feel more irritable than normal, a term scientists call “hangry.”
The upside is — with little glycogen left — fat cells in your body release fats into your bloodstream. The fat cells head straight to your liver, where they're converted to energy for your body and brain. So, you are literally burning fat to survive.
Blood samples show that people who had fasted for 12-24 hours experienced a 60% increase in energy from fat, with the biggest change occurring after 18 hours. This is the benefit to intermittent fasting because it puts you in a state called ketosis. And it's why researchers think intermittent fasting could be the key to a longer, healthier life.
The process of burning fat releases chemicals called ketones. In the brain, ketones trigger the release of an important molecule called BDNF. BDNF helps build and strengthen neurons and neural connections in areas of the brain responsible for learning and memory. Which could explain why a boost in ketone production has been shown to improve memory in people with early signs of dementia in as soon as 6 weeks. Increasing ketones in the body is also a common treatment for patients with severe epilepsy.
You don't necessarily have to fast to boost your ketone levels. Introducing more fatty foods into your diet and cutting back on carbs can have a similar effect. A group of people who tried this method for 3 months not only lost weight and body fat, but also saw a decrease in blood pressure and a hormone (IGF-1) that is related to aging and disease.
But scientists have discovered that fasting increases ketone levels more. Ketogenic diets can increase ketones 4-fold whereas fasting has been shown to increase ketones by up to 20-fold. As a result, fasting — compared to a ketogenic diet — may have a stronger, more beneficial effect on overall health.
Yet many Americans who eat three meals a day with snacks in between never reach ketosis, and therefore aren't producing enough ketones to promote good health.
Fasting and ketosis have been a key to our survival from the beginning. They helped our ancient ancestors survive through bouts of starvation.
And today, they're becoming recognized as a way to help keep future generations mentally and physically disease-free.

Fasting is the natural Safe way to go! Forget about Ozempic I’ve been fasting now for about three months. I’m down 19 pounds. I’m doing 18/6 fast.
Ive tried it and it’s basically a way of putting your body into a calorific deficit. And that’s it. No magic about it. A lot of people eat what they want in the window I tried it and I didn’t lose any weight. So that means you still need to watch what you eat. Which means you need to track your calories. So what is the point of waiting until 12 o’clock noon to eat to track your calories when you can spread them out through the day? If your deficit is 2200 calories then you could easily split that into 3-4 meals and you wouldn’t have to cram it into an 8 hour window. I think the only positive I found from it was gut health. Stop eating at a certain time of day seemed to improve my gut. Did I feel anymore energetic? No. I felt like crap while I was fasting. And when you’re doing work and having kids and going to the gym that’s not good. If it helps you lose weight that’s fine. But it’s not the optimal way to do it and I think these f*ckers are just trying to make money out people like nearly every other fitness trend is doing this day and age. And that picture of Hugh Jackman? Blokes on anabolic steroids.
im just poor😂😂
Poor people fast everyday even festive season 😅
I do 24 hours. Only twice in my life. But I’m afraid to do 72 hours cuz I’m skinny..??
MOST of all its free and your expenses on food would be cut off
I lost 7 pounds in one week on keto and intermittent fasting! It’s amazing❤
Read your bible! (KJV, preferably) ❤️
I've been doing IF for 3 years. I'm 54 years old man, lost 35 lbs, and I feel great. I do 18/6, and at leat 3 times a month I eat once a day. Stay healthy
It is from the teachings of Prophet Muhammad peace be upon him to fast on Monday's & Thursday ( two times a week ) ❤
O believers! Fasting is prescribed for you—as it was for those before you 1—so perhaps you will become mindful ˹of Allah˺.
QURAN CHAPTER 2 VERSE 83
THANK YOU FOR ISLAM ❤
I Fast between 5pm and 12pm and sometimes from 5pm to 5pm.
I am a 37 year old male and I've lost 20kg just by fasting 16 hours for 7 months. I was 83kg when I started this and now 62.
Humans where never designed to eat regularly, the food industry have lied for years
It improves Brain 🧠 power, my personal experience.
i fasted for 18 hrs daily and loved it, had to stop tho couldn't afford the protein needed to continue.
I've tried IF (16:8) in the past for 3-4 years. Since I was already lean with very active life style, and eating about the same amount as I used to throughout the day, I didn't lose weight. However, what I've seen was that I didn't catch a flu at all during that 3-4years. I was actually surprised as growing up I used to catch flu accompanying with high fever at least once a year! After that I've stopped IF because I've also noticed my self eating too much for dinner before the fasting window. I started to eat breakfast early morning and end the last meal of the day around 9-10pm. Guess what, my annual fever came back.
Important to note the hangry 😡 effect only takes place if your bodys not used to burning fat. Once your used to fasts your hormones are ready for it.
Can i chew gum and/or drink coffee with sugarfree creamer to achieve similar effects?

Prophet Muhammad said: fast to have a better health
صوموا تصحوا
The gullible will fall on the lastest AHA's "study," they prey on those who easily believed everything. Countless of doctors from all over the world debunk the big pharma's lies! Ofc, IF is a free way to be healthy, what will the big pharmas get if you are not getting sick or being healthy free! Watch Dr.Berg, he's one of the countless doctors who genuinely care about people. IF saved me from different health issues.
Canadians elementary and high school students all do intermittent fasting. There’s no school meals provided.
What about the new research that says that IF results in death by heart disease?
A recent study conducted by American heart association found that intermittent fasting increases the risk of death linked to heart damage by 91 percent.
Alhamdulilah
Allahu Akbar Ramadan mubarak 2024
The Keytones was also the name of my a cappella group at Barton College
I'm already thin. Is it okay for me to continue doing this?
carnivore diet is deadly
I last ate 22 hours ago
I FEEL LIKE A MILLION DOLLARS! That's why I looked this stuff up.
Pfft. Ten years ago, these same people were saying we should eat six small meals spread throughout the day. Now they're saying one large meal. Butter is in, I remember when it was out. Fat is in, I remember when it was out. Egg yolks are in, I remember when they were out. And when something's out, these nutritional fashionistas make it sound like you're comprising your health hy not following trends.
You can definitely be in perfect health with three square meals a day. By all means, experiment eating and not eating a different times of day and see what works for your body and lifestyle. But anyone telling you that their way is the best way, or that human nutrition is finally figured out, is probably not being fully honest with you. Listen to these people, and you'll be revising and reversing your diet to follow the latest flawed studies every few years. The best nutritional advice is time-tested, eating traditional healthy foods that have been known as such for centuries. Let the fanatics claim tomatoes are a nightshade and will kill you, or that you'll never lose weight eating breakfast, lunch, and dinner. Eating fruits and vegetables and healthy proteins is obviously healthy, and you can get in shape eating healthy foods in moderation and exercising, no matter what time of day you do it or how you spread it out.
All of our bodies are different and respond differently to different foods and meal routines. We each need to experiment to find what's healthiest for us. Don't take nutritional trends too seriously, just eat mostly healthy foods and don't eat too much. And try to at least walk daily, or better yet have regular exercise.
Some people waste their entire lives trying to prolong them. The most important lessons, the hardest ones to learn and act upon, are the obvious ones almost everyone innately knows. You almost certainly already know if you're overweight and you are gaining or losing weight. You already know if you're not exercising enough and eating unhealthy foods.
I've started doing this I do the 16/8 fast my body feels much better and I feel much more healthier and have been much happier within myself
Thanksss
It also makes your cock bigger
I've just started intermittent fasting, starting at 8pm and break my fast at 10 am the next day …I currently am feeling so energetic
The brain functions so much better when fasted, the differences I have noticed are almost immeasurable. I would do OMAD for life if I didn’t do strength training. It’s a shame the brain and body function more optimally in different states.
Intermittent fasting is for worker? Or non worker?
All the prophets Have recommended us fasting…Like Moses (peace be upon him ) , Jesus (peace be upon him) and Prophet Muhammad (peace be upon him ) …they have recommended us these things thousands of years ago and hence now science is proving this too .
as a stroke survivor who IM fasts 16/8 through the week and 24 hours for two days on the weekends aI can definitely concur that the majority of the facts on this video are truth!!🙏🏽😘❤️🩹🙏🏽💪🏽💪🏽💪🏽💪🏽🙏🏽👍🏽
Go wolverine🎉
Just don’t eat at night before bed
