3 Scientifically Proven Benefits Of Fasting


For hundreds of years, fasting has played
an important role in a number of different cultural and religious practices around the
world. For those who don’t know, fasting refers
to a set period of time during which a person abstains from either all food and drink or
restricts their diet to only a few select food types. While limiting your nutritional intake for
a period of time sound counterintuitive to your health, some specialists such as registered
dietician Rachel Link suggest that fasting may potentially bring some unexpected benefits
to a healthy lifestyle. Before we start, break your new video fast

If you’re looking to shed a few extra pounds, then fasting may be an obvious solution. Apart from the obvious fact that fasting reduces
your overall calorie intake, a study published in the American Journal of Clinical Nutrition
suggests that fasting may also increase your body’s production of a neurotransmitter
knbown as norepinephrine, which has an effect on boosting your metabolism. Additionally, another study showed that participants
in a fast also experienced a significant increase in the production of human growth hormone,
or HGH. HGH is a naturally-occurring protein within
your body that plays a number of key roles related to your health, including weight loss
and muscle strength. By increasing the body’s secretion of HGH
as well as speeding up their metabolism, a person fasting could potentially see a reduction
in fat while still maintaining muscle mass; this means that intermittent fasting could
indeed prove to be a viable weight loss option for certain individuals. 2. Fasting Helps Your Blood Sugar
According to a study published in the World Journal of Diabetes, fasting for short-term
and intermittent periods of time was shown to lowered levels of blood sugar for participants
struggling with type 2 diabetes. Another study from the Journal of Laboratory
and Clinical Medicine, both intermittent fasting and alternate-day fasting were found to be
equally and significantly effective when it came to decreasing levels of blood sugar within
the body. These findings are noteworthy because decreasing
blood sugar benefits your body’s health by reducing its resistance to the hormone
insulin. By decreasing resistance and making your body
more susceptible to insulin, your bloodstream is able to transport glucose directly to your
body’s cells much more efficiently. Of course, if you already struggle with diabetes
or abnormally low blood sugar, you might want to hold off on fasting until you’ve had
time to discuss the potential pros and cons with your doctor. We’ll get into more detail on the safety
precautions involved with fasting a little later in this video. 3. Fasting May Prevent Illness
There are a variety of ways in which nutrition researchers have linked fasting to a number
of potential health benefits. For starters, fasting may help prevent the
onset of chronic inflammation, which can lead to unwanted health conditions such as heart
disease and arthritis. A study in volume 32 of Nutrition Research
monitored 50 adults who participated in intermittent fasts over the course of a month; the result
was that participants exhibited significantly decreased levels of inflammatory markers. Additionally, a small study published by the
Obesity Society also indicated that fasting on alternating days may be an effective way
to reduce your body’s levels of LDL or “bad” cholesterol by 25 percent, as well as lower
the number of triglycerides in your blood by up to 32 percent. Not only does this reduction in bad cholesterol
and triglycerides help regulate your body’s blood pressure, but it can also serve to improve
your heart’s health by reducing the risk of heart disease. In addition to helping your heart, fasting
may also benefit your brain as well; studies involving mice have indicated that fasting
in rodents help improve both brain function as well as brain structure. Similarly, other studies such as one published
by the Journal of Molecular Neuroscience have suggested that intermittent fasting may also
help stave off neurodegenerative disorders in rodents by increasing the generation of
nerve cells and enhancing cognitive function. However, it’s worth mentioning that studies
examining the potential affects fasting may have on the mind is so far limited to animal
research (at least at this time of writing) and so more research will need to be conducted
to determine if these findings apply to human beings as well. One important thing to note about fasting
is that even with these potential benefits, a fast might not necessarily be ideal for
everyone. As such, Rachel Link suggests that anyone
who’s currently thinking about experimenting with a fast should first consult with their
doctor, especially if you intend to fast for any period longer than 24 hours. Specifically, Link suggests that anyone who
suffers from diabetes should try to avoid fasting, as well as anyone currently afflicted
with low blood sugar. This is because fasting can potentially result
in major fluctuations to your body’s blood sugar levels; this, in turn, can cause dangerous
blood sugar spikes and crashes to occur. For older adults, adolescents, and individuals
who are currently underweight, it’s recommended to avoid fasting unless accompanied by professional
medical supervision. If you do choose to begin a fast, there are
additional precautions you should consider to make sure you’re fasting as safely as
possible. For starters, people fasting for long periods
of time should avoid engaging in overly physical or strenuous activity, and should make sure
to get as much rest as possible. Link also suggests that prospective fasters
should also make sure to stay hydrated, as well as make the most of their eating periods
by populating them with foods that are rich in essential nutrients. If you plan on beginning a fast in the near
future and your doctor’s given you the go-ahead, you should also make sure to research the
different subcategories of fasting to see which type of fast is the best fit for you. Some subtypes of fasting, such as intermittent
fasts, are designed around alternating between periods of restricted food intake and a regular
diet. Other types, such as partial fasting or calorie-restricted
fasting, instead simply limit the amount of food you consume, or even just specific types
of foods such as animal products, processed foods or caffeine. According to Link, it may even be best to
experiment with different types of fasting to see which is best suited to your health-related
needs. While usually reserved for certain types of
traditional, cultural or religious practices, scientific research has suggested that a fast
could potentially be beneficial to your health by improving weight loss as well as by assisting
with some of your body’s essential functions. By taking the right precautions and ensuring
you fast in a safe and controlled environment, you can reap some of these potential rewards
yourself; just make sure that you know your body’s natural limits beforehand in order
to avoid spreading yourself too thin. If you’re lucky, you might even be able
to see some “fast” results! So now, dear viewers, we’d like to pass
the conversation on to you. Do any of you have any experience with fasting? Would you be willing to share some of your
opinions and experiences related to it? We’d love to hear you weigh in, so be sure
to leave a comment below this video to help us keep the discussion going. Since fasting has a place in a number of different
cultural and religious practices, all we ask is that you keep an open mind and keep the
discussion as respectful as possible.

    As a Muslim, We need to fast from Sunrise to Sunset for a month (29/30 days). Meaning that in some country, we need to abstain from food and drink for 20hours. However it is not all about food or drink. During that month we should improve ourself by becoming more kind, generous (We have to give a lot to different charities…that is why muslims are the most generous). We also need to abstain from smoking, intimate relationship….

    Reason number one to fast is that it restores your relationship with God and makes you holier. 1 Corinthians 5:5, destroy the body that the soul may be saved.

    Back in April of 2010 my darling mother died of cancer. For the year previous to that (2009) I took care of her day and night for a year at home which meant that for that whole year I slept very little and at unusual times depending on my mother's needs. After her passing my sleep cycle was so mixed up that I could only sleep about 3-4 hours every night if I was lucky. In January of this year I started intermittent fasting (16 hours fasting to 8 hours eating) because healthy plant based, whole food diet was not getting any results concerning my sleep. After only about 8 weeks of this change, I am now sleeping better than when I was a teenager. Seven and eight hours of sleep have become the norm and not the exception. I wish I would have done this years ago and could have saved myself almost 9 years of dragging myself around being tired, depressed and sickly.

    I fast for spiritual reasons but it does help you health wise. I done a fast of restricting certain types of foods and sugar for 40 days. I've done 21 days, 30 days etc. The one fast that I've always wanted to do is the water fast where you consume no food but just water. I feel like I could do it but I'm a little nervous about. I've lost weight during those fast, and got a lot of peace and clarity in my life. My focus was even better. Now the fast without any food or water at all is a tough one. I'm on high blood pressure medication so I think I have to eat something to take medicine. I eventually want to be off that medicine.

    I just did 12 day water fasting and vlogged my daily journey on my channel. I lost 25lbs of weight. It felt so good. I will continue my fasting journey with IF I prefer OMAD

  8. Patty p

    Im on keto, also OMAD and IF. I started fasting on Tuesday, today is my 4th day. Not hungry at all. Only black coffee. I feel great😊

  9. LrdRgo

    I’m on My 20th day fasting right now!!!!
    Only Water that’s it. And I feel great stronger and less stress! I don’t feel hungry at all and I watch food videos on YouTube all the time and switch back to watching Fasting videos ! It helps me not to miss food when I’m fasting!

    I never fasted and still lost weight ,just stay away from the high glaucimic foods and moderate excercise and my weight fell off and I really don't like fasting cause I think it can really restrict the body of vital nutriants that it needs everyday.

    I was on a weight loss journey, I exercised and ate a little healthier, I was doing pretty good and seeing results. But hit a Plato. I started intermittent fasting, It was a little difficult at first, I craved food and felt hungry, but learned it wasn't hungry I felt, it was a food addiction, mistly sugars. after a few hours the hunger feeling went away, and only after I felt real hunger, where my stomach growled, did I eat, I'm doing the 9-2 fast and eat twice a day, for about 3 weeks, eating the same, just a set time, any time I choose, I've lost roughly 10 lbs. And feel clear. Full of energy, the side effects from fasting are going away, like headache. Weak and irritable. My advise to anyone wanting to try it, is b patient, listen to ur body, not ur cravings or ur mind. Choose the healthy foods and the best time for u to fast, drink plenty of water, green tea, no pop. U will feel so much better. We dont need to eat all the time like we r taught. We could do so much more with our time and money!

    Water fasting really helped my blood pressure,I was fasting 24 hours a day only eating at 6pm one time a day.The blood results were good but my phosphate levels dropped below normal.
    I became dizzy and felt weak,so I will go back to my original eating plan of small meals every few hours.

  13. yolanda jerginson

    No no no! Don’t ask your doctor shit. They don’t give a shit about getting you healthy. That would put them out of business and the pharmaceutical companies that line their pockets. Think and know your body for yourself. It will talk to you.

    Fasting is a wonder feeling and timed correctly it can be a reset button and may help some taking other drugs and for a person who is taking them for other reasons not related to food and calorie consumption. The Bible tells us that it was done in earlier times for good reason. Safety is most important when it comes to our bodies so you should consult your physician if needed.

  15. E L1

    I lost 40 pounds in 10 days. It was March 2018, I had lost a medication in the last couple of days in Feb. A nurse took away a antidepressant-painreliever cold turkey, as it worked out of my system I began the most horrible 3 months I have ever lived through. No more than 12 hours of sleep in a full 8 day period, this went on for almost 3 full months. I never imagined it was possible for the human body to endure. 40 lbs and several times I thought I was going to die, I wanted to die from the pain and being wide awake nearly 24 hours a day, I didn't want any food, I wanted to feel better was all. It's now a year later and I am still working on getting my body healthy as it was before all of this. Please consult your physician first ! Your bodies health is so precious !

    I am 72 years old. A man. I have diabetes, high blood pressure, which gets really high sometimes.
    I tried to control blood sugar by eating less carbohydrate. I walk every morning for 45 minutes. All that help. I tried fasting a month ago. First times for four days only and drinking only water. I broke my fast by drinking watermelon juice and papaya juice. I felt lighter, my mind got clearer. After waiting and eating well for 2 weeks I fasted again for six days drinking only water. My puffy face is gone. My face looks brighter, my eyes got better, my foggy brain symptom is gone. Blood pressure lower, blood sugar lower.
    Now I need less medication. Pain in my knees is gone. I can walk more without any pain. Back pain also gone. Now I can sit for an hour or more without needing to get up.
    I am preparing to fast again, this time hopefully longer days than before. I do not set an exact days to fast. I listen to my body.
    Thank you for your video. I learned something more.

    I completed for one month, 3,1,2,1 fasting. I designed a fast where I ate on Wed and Sunday only. After a month I had lost 22 pounds and 4 inches of waistline. Then I changed it

  18. CherylbethCarter Carter

    I am now on my tweaked fast I eat Wed eve and Thursday Morning then Sat Eve and Sunday morning. I have just changed it up this is my first week.

  19. CherylbethCarter Carter

    After my 1st month 3,1,2,1 fasting , I reported to my doctor weighed in lighter, reduced my cholesterol from 220 to 190. I take magnesium before bed and zinc in the morning.

  20. CherylbethCarter Carter

    While fasting, I use coffemate in my coffee and for lunch and dinner I have hot green tea with a drizzle of honey. For funsy not everyday I have a cup of pickle juice for the vinegar and salt.

  21. CherylbethCarter Carter

    Good luck with your fasting. The secret about not eating is the hot tea or hot coffee, which gives you the feeling of fullness.

  22. DOCBAR

    Fasting cures diabetes period! I beat diabetes and no longer take meds. Anyone that tells you different doesn't know jack shit. I was a diabetic for 5 years and was only getting worse. After going into ketosis and eating one meal a day i now have normal blood sugar and am in perfect heath. Haven't even told my doctor because he is a brainwashed idiot. Sorry but most doctors don't know shit about anything.
