Intermittent fasting refers to eating plans that alternate between fasting and eating periods. The goal is to systematically starve the body long enough to trigger fat burning. While research is still underway and the method may not be suitable for everyone, there is evidence that, when done correctly, intermittent fasting can help lose weight, lower blood pressure and cholesterol, prevent or control diabetes, and improve brain’s health.
During a meal, carbohydrates in food are broken down into glucose. Glucose absorbs through the intestinal wall into the bloodstream and is transported to various organs, where it serves as the major energy source. Excess glucose is stored for later use in the liver and adipose tissue, in the form of glycogen and fats. In between meals, when the body is in the fasted state, the liver converts glycogen back to glucose to keep supplying the body with energy. Typically, an inactive person takes about 10 to 12 hours to use up the glycogen stores, although someone who exercises may do so in much less time. Once the reserve of glycogen in the liver is depleted, the body taps into energy stores in adipose tissues. This is when fats are broken down into free fatty acids which are then converted into additional metabolic fuel in the liver. Thus, if the fasted state lasts long enough, the body burns fat for energy and loses that extra fat. Losing the extra fat is translated into a range of associated health benefits.
Insulin is the hormone required for driving glucose into cells. Insulin level is regulated to match the amount of glucose in the blood, that is, high after a meal and low between meals. Because insulin is secreted after each meal, eating throughout the day keeps insulin levels high most of the time. Constant high insulin levels may de-sensitize body tissues, causing insulin insensitivity – the hallmark of prediabetes and diabetes type 2. Fasting helps keep insulin levels low, reducing diabetes risks.
Fasting also has beneficial effect on the brain. It challenges the brain the same way physical or cognitive exercise does. It promotes production of neurotrophic factors, which support the growth and survival of neurons.
Fasting, however, is not for everyone.
Fasting can also be unsafe if overdone, or if not done correctly.
There are several approaches to intermittent fasting, but the easiest to achieve is perhaps the one that simply extends the usual nighttime fast. A daily cycle of 16-hour fast followed by a 8-hour eating window is usually sustainable.
For intermittent fasting to be safe and effective, it must be combined with balanced meals that provide good nutrition. It is important to stay hydrated, and know your physical limits while fasting. The fast must be broken slowly. Overeating after fast, especially of unhealthy foods, must be avoided.

I am size xl and then I go through fasting I am small now, Just eat 1times daily and dont eat extra snacks, it is very effective trust me
I need to lose 30kg in 5 months starting now. Will this work?
For example, I'll eat, let's say, from 7 am till 13:00, not all the time but breakfast and lunch and that's it. The rest of the time, I'll only drink water.
Do you reckon ok, let's say 20kg, to be more realistic will i lose 20kg in 5 months? I'm only 22 and just under 90kg need to be around 60 – 70kg for my height.

Islamic fasting started in the 2nd year of Hijrah (624 CE), as stated in the Quran (Surah Al-Baqarah, 2:183). It became a key act of worship during Ramadan.
Health Benefits
1. Weight Control: Reduces body fat and helps manage weight.
2. Improved Metabolism: Enhances insulin sensitivity and regulates blood sugar.
3. Heart Health: Lowers cholesterol and blood pressure.
4. Detoxification: Promotes autophagy, cleaning damaged cells.
5. Brain Boost: Stimulates brain function and reduces stress.
6. Longevity: Supports cellular repair and anti-aging processes.
Does it matter what weight you start at? I’m about 57kgs and want to loose 10kgs or so. Brings me to a slightly healthier weight though my current weight isn’t too bad
I did intermittent fasting for months, just one meal a day – and when i tell you that that one meal was gigantic I mean it – but I managed to stay fit throughout. No exercise, nothing. Healthy weight. No guilt. Just the pleasure enjoying the food
This is the best explanation of Intermittent Fasting video I’ve seen. Never get tired of it 👍🏾😊
in 2022 I was 300 pounds I had an eating window of 1 hour every day and I lost 120 pounds in a year and a half with not going working out I just walked a lot. I am back intermittent fasting to get down to 150 pounds or were I feel good at. Every weak on Saturday I would make seven meals two chicken drum stick brown rice with a cup of mixed vegetables it was easy. Two PM two three PM was when I ate at only no cheating.

23/1 Is The Way To Go💐
My doctor put me on the following diet: do not eat anything until after 11:00am, and don't eat anything until after 7:00pm, and I've lost 50lbs! You can see the video results of this diet if you YouTube the following: "JBL SYNTHESIS CREATOR", this is when I weighed 250lbs. And if you YouTube: "howtohomelife", you will see eight recent videos, where I weigh 200lbs and I'm still losing weight. I was tired of carrying around four bowling balls! David Riddle
Intermittent fasting is good for establishing a good baseline, but the magic is in the extended fasts. The first major step is going to bed without eating for the very first time. That night, your body won't have to deal with digestion, and all the energy will be allocated to cleansing and repair. For me, passing that stage is earning the yellow belt in fasting.
I lost 10lbs an 14 days no exercise
Can we start with 12 hours?
Can I drink coriander-jeera water in fasting window
In Hinduism we do ekadashi fast Hinduism is way of life
0:27 *cure

Intermittent fasting saved my life too 😊
Can i have breakfast n lunch before the fast start
i want to start fasting not because i want to lose weight but i just want to do it. the problem is im underweigt and my bmi is severely low (15.4). unfortunately even tho i badly want to do this, i cant bcs my dad self diagnosed me with anorexia, im underweight with a bmi of 15.4 and im also just a teen.
Since a kid is only eat once a day maybe 2000 calories but i gain weight i don't drink cokes never like them or sweets o usually drink milk or water or juice i can't eat a lot or my stomach hurts can anyone explain this im 6 1 and 240 pounds but i hardly eat …
I will not eat 8 then fast 16 because that is a slippery slope designed to keep you fat. I'll take 6 hours eating and 18 fasting because I know it will not hurt me. Most of us eat too much anyway.
thank you ! great video.
I was considered obese and on my way to diabetes and high blood pressure. As an emotional eater, this is the best eating program for me. I am on a 22/2 fast on most days, which is usually 5 days a week. I also exercise and have lost a stubborn 4 pounds. Now I am trying to lose these next 10 pounds so that I will get out of the overweight category and be a normal weight. The fat on my back is also going away. I feel good and feel much better.
Ive been eating once a day for a few years i really feel great
Can I chew gum while the fast is happening?
I started doing this style of eating, 8 hours eating, 16 hours fasting..I have been doing this for 6 to 8 weeks and gained 2 lbs..I haven't cheated one time but I am ĝoing to continue this eating style for 2 or 3 months..
