The Health Benefits of Fasting

Will Carroll

There has been much contention in the scientific field about whether or not fasting is beneficial to one's health. Fasting is an integral part of many of the major religions including Islam, Judaism and Christianity. Many are dubious as to whether the physiological effects are as beneficial as the spiritual promoted by these religions. There is a significant community of alternative healers who believe that fasting can do wonders for the human body. This paper will look at the arguments presented by these healers in an attempt to raise awareness of the possible physiological benefits that may result from fasting.

Fasting technically commences within the first twelve to twenty-four hours of the fast. A fast does not chemically begin until the carbohydrate stores in the body begin to be used as an energy source. The fast will continue as long as fat and carbohydrate stores are used for energy, as opposed to protein stores. Once protein stores begin to be depleted for energy (resulting in loss of muscle mass) a person is technically starving. (1)

The benefits of fasting must be preceded by a look at the body's progression when deprived of food. Due to the lack of incoming energy, the body must turn to its own resources, a function called autolysis. (2) Autolysis is the breaking down of fat stores in the body in order to produce energy. The liver is in charge of converting the fats into a chemical called a ketone body, "the metabolic substances acetoacetic acid and beta-hydroxybutyric acid" (3), and then distributing these bodies throughout the body via the blood stream. "When this fat utilization occurs, free fatty acids are released into the blood stream and are used by the liver for energy." (3) The less one eats, the more the body turns to these stored fats and creates these ketone bodies, the accumulation of which is referred to as ketosis. (4)

Detoxification is the foremost argument presented by advocates of fasting. "Detoxification is a normal body process of eliminating or neutralizing toxins through the colon, liver, kidneys, lungs, lymph glands, and skin." (5). This process is precipitated by fasting because when food is no longer entering the body, the body turns to fat reserves for energy. "Human fat is valued at 3,500 calories per pound," a number that would lead one to believe that surviving on one pound of fat every day would provide a body with enough energy to function normally. (2) These fat reserves were created when excess glucose and carbohydrates were not used for energy or growth, not excreted, and therefore converted into fat. When the fat reserves are used for energy during a fast, it releases the chemicals from the fatty acids into the system which are then eliminated through the aforementioned organs. Chemicals not found in food but absorbed from one's environment, such as DDT, are also stored in fat reserves that may be released during a fast. One fasting advocate tested his own urine, feces and sweat during an extended fast and found traces of DDT in each. (5)

A second prescribed benefit of fasting is the healing process that begins in the body during a fast. During a fast energy is diverted away from the digestive system due to its lack of use and towards the metabolism and immune system. (6) The healing process during a fast is precipitated by the body's search for energy sources. Abnormal growths within the body, tumors and the like, do not have the full support of the body's supplies and therefore are more susceptible to autolysis. Furthermore, "production of protein for replacement of damaged cells (protein synthesis) occurs more efficiently because fewer 'mistakes' are made by the DNA/RNA genetic controls which govern this process." A higher efficiency in protein synthesis results in healthier cells, tissues and organs. (7) This is one reason that animals stop eating when they are wounded, and why humans lose hunger during influenza. Hunger has been proven absent in illnesses such as gastritis, tonsillitis and colds. (2) Therefore, when one is fasting, the person is consciously diverting energy from the digestive system to the immune system.

In addition, there is a reduction in core body temperature. This is a direct result of the slower metabolic rate and general bodily functions. Following a drop in blood sugar level and using the reserves of glucose found in liver glycogen, the basal metabolic rate (BMR) is reduced in order to conserve as much energy within the body as can be provided. (2) Growth hormones are also released during a fast, due to the greater efficiency in hormone production. (7)

Finally, the most scientifically proven advantage to fasting is the feeling of rejuvenation and extended life expectancy. Part of this phenomenon is caused by a number of the benefits mentioned above. A slower metabolic rate, more efficient protein production, an improved immune system, and the increased production of hormones contributes to this long-term benefit of fasting. In addition to the Human Growth Hormone that is released more frequently during a fast, an anti-aging hormone is also produced more efficiently. (7) "The only reliable way to extend the lifespan of a mammal is under-nutrition without malnutrition." (5) A study was performed on earthworms that demonstrated the extension of life due to fasting. The experiment was performed in the 1930s by isolating one worm and putting it on a cycle of fasting and feeding. The isolated worm outlasted its relatives by 19 generations, while still maintaining its youthful physiological traits. The worm was able to survive on its own tissue for months. Once the size of the worm began to decrease, the scientists would resume feeding it at which point it showed great vigor and energy. "The life-span extension of these worms was the equivalent of keeping a man alive for 600 to 700 years." (8)

In conclusion, it seems that there are many reasons to consider fasting as a benefit to one's health. The body rids itself of the toxins that have built up in our fat stores throughout the years. The body heals itself, repairs all the damaged organs during a fast. And finally there is good evidence to show that regulated fasting contributes to longer life. However, many doctors warn against fasting for extended periods of time without supervision. There are still many doctors today who deny all of these points and claim that fasting is detrimental to one's health and have evidence to back their statements. The idea of depriving a body of what society has come to view as so essential to our survival in order to heal continues to be a topic of controversy.

Fasting

I fast for a month, 30 days and eat absolutely nothing! I drink plenty of water and as long as I keep hydrated I feel fantastic. People believe this is impossible because it is not common in the US. I do this for the month of March every year and have been able to maintain a healthy body weight. Since I started this 9 years ago I have perfect blood sugar, blood pressure, and my rheumatoid arthritis has been in complete remission. I am pain free and have plenty of energy. I do my best to eat healthy the rest of the year but I am no saint. I do occasionally overdue, but try to avoid processed foods. I enjoy an occasional drink or two on the weekends and eat well. I am 50 years old and have never felt better in my life. So please do your homework before you accuse people of lying. Just because you don't understand it or are unfamiliar with it doesn't mean it is not true. Live and let live.

THATS NOT BULLSHIT

I know that your one of those people who don't understand the concept of fasting.And you can go 40 days without juice,vegetables,or other liquids.But you must have water or you will not lose weight ,plus it is for god.SO GEUSS WHAT TRY IT!!!!!!!!!!!!

Serendip Visitor's picture

not crazy

People say three minutes without air, three days without water, three weeks without food. I've made it eight weeks without food and I'm fine.

fasting 40 days

I just finished a 40 day fast a few weeks ago and I'm still here and feeling great!! : D

Serendip Visitor's picture

You can fast 40 days on water

Sorry. you are wrong. Using harsh language does not make your position correct. There are many documented cases of people fasting on water for 40 days or longer. One does not need "juices". The intake of any calories actually reduces the effectiveness of the fast.

Anon Mouse's picture

agree

I've done a 30 day water fast with absolutely no cheating. Only some diet pop and black coffee was consumed, but nothing with caloric value.
Most people with significant fat stores can fast fairly safely for extended amounts of time.

fasting

I did my first fast at age 30 o the advice of a Chiropractor, the 3rd and fourth days were brutal, headaches and photophobia, I was pretty much bedridden. It was explained to me that due to my past indiscretions, (drug use and work related chemical exposures) these toxins were now being released from my fat cells and had to be detoxed by the liver. After the initial bad time I felt human again and within days I was riding my bike to school 3 miles each way and feeling great. That first fast fast was an eye opener. I tried to fast at least once a year since, (I'm 60 now). I try to start it when my family is gone for a long weekend or so as I don't want to listen to how bad it must be for my body. I never get the headaches anymore, (don't pollute my body like I used to and I think I've done enough fasting to clean out the bad stuff). I'm not hungry at all, my biggest problem is the boredom of not eating. I'm going on a bike ride today and will break the fast tonight. Although not the intent of the fast I have lost 11 lbs during this week and saved money on groceries. Like others have said try it 3-4 days to experience the bad parts before you try it for longer. One other reason for bad headaches is caffeine withdrawal, get off the caffeine before you try this or the headaches will be magnified.

Hello,
There is a GREAT!!!! book written ny Paul Bragg, The Miracle of fasting" by a Dr who lived until 95 years old!!!!

YOu SHOULD NEVER!!! NEVER jump into fasting for more than 24 hrs a week. Sounded like you said you did it for 4, 5 days in a row for the first time in a life. Please read a book on fasting first before doing, or you'll do more damge than good to yourself.

Best of luck to you in this wonderfull, rewarding lifestyle: Fasting

You must be one of those really annoying people who refer to people as "People!" when you want to make a point. I disagree with you completely. There are many kinds of fasts as mentioned in the article.

Fasting

Could anyone inform me on the notion of instead of fasting for an extended amount of time (say, fasting for 15-40 days), fasting for two days a week consistantly? Would the benefits be relatively similar?

Serendip Visitor's picture

My biology professor freshman college

My physiology was more adamant about fasting than any other subject discussed in the course. The answer to your question is no, fasting for two days does not have similar effects to that of extended fasting. Once you have breached 48 hours you enter a second phase of fasting, which lasts until the 22nd day (for the average human being-depending on their body fat ratio), where your body begins absorbing adipose tissue (fat cells) during digestion. Before this happens the body absorbs carbohydrates from meals in the past 48 hours. Fat cells store toxic matter, part of the reason obese individuals have more health issues. During fasting fat cells are released from storage into the blood stream. Along with with the cells goes the toxic matter, simply because that is where toxic matter is stored long term in the human body. During the first two days this toxic matter in store is not released. One benefit listed is a lowering rate of cancer. This is because toxic matter that would otherwise be stored would be released from the body. Cancer is developmental, if you prevent toxic cells from transforming into malignant cells they will never have the ability to kill you, unless your immune system is already predisposed and particularly weak and contains less white blood cells, or other immune system cells that could fend off cancer. These fat cells that are divulged from store and released into the blood stream are the main reason fasting is so crucial to human health. The article states that when animals begin dying or have certain sicknesses the sensation for appetite is relinquished. The minds focal point becomes the immune system under such circumstances. So not only is high toxicity adipose tissue released into the blood stream and then out the body, the immune system also can kill toxic properties that exists when released. Overall, fasting has tremendous overall results for homeostasis and prolonged lifespan.

question

hi there, thank you for this info makes a lot of sense , it helps me understand my body and my son's also. me and my 12 yrs old son already started fasting only one day per week. as i understand that is not the real beneficial amount of time . woul you please give us a little guidance like, what time frame should we start with, for a good detox fasting. we never did more than 1 day a week. please respond and thank you so much

Fasting..

Fasting has been a part of my life for some years, Ive never fasted over 14 days but March 1st I will go for a 21-31 day fast, I have no doubts that I can accomplish them.. However my fiances family and our friends when they find out think I am crazy and I am starving myself etc. etc which bothers me.. This article was just the confirmation that I needed, that with proper education and facts I know Im not crazy.. Ive put fasting off for almost a year for the sort of "bullying" I got... But I am doing this for me, tried and tested always with amazing results and a feeling of being renewed.

Word of advice to those looking into fasting, If you weigh 155 lbs, it is not beneficial to do a 40 day water fast the weight lost could result in starvation depending on height.. and if first timers, start slow 1 day-3 day-7 day etc taking on 40 days first time isnt a good idea
What you eat/dont eat prior to a fast will def. help.. 1-2 weeks before try to eliminate as much sugar and caffeine consumption as possible, eat easily digestible foods and the closer to the fast eat more high water content food(high water veg, soups etc.) this will make the "detox" effects feel less extreme, also an herbal digestive tea 2-3 times a day a week or so before and 1 a day while fasting helps get rid of the"bulk" in the intestines.. I use Tibetan tea with great results, however may not be found everywhere(Im in Isreal).
And most def. educate yourselves on proper ways of starting-breaking fasts!! Good luck!

Fasting

That is great advice . To prepare the body and mind prior to fasting will help a great deal. I am planning to fast for two weeks as I have 28% body fat and being 55 I need to shed some stored fat which has built up over the years . I go to the gym regularly as well but still have severe bloating. Apparently this is fat stored around the internal organs that fasting will eliminate.Following the initial fast, I plan to fast once a week , 24 hour periods , and try to make it a part of my lifestyle. I also need to give up smoking ( doesnt help with the toxins issue ) . This forum has been very helpful :-)

Hello, my name is Jane and I

Hello, my name is Jane and I was truly blessed by the comments shared in response to this article. I am currently 265lb with a raised bp of 140/80 and brain fog. I have previously fasted for spiritual purposes, and I found it to be very beneficial. Needless to say I haven't fasted for about two years now and I can see the effect it has had on my overall life. I have been inspired to resume the disclipline of fasting so that I may once again embrace and live my life to the fullest, instead of simply going through the motions.

How is it going. Its amazing to see when we begin to fast with with seeking his face. Something comes up to throw off.

Fasting and nutrition

I've personally experienced that fasting definitely gets easier the more you do it. When I first started fasting it was quite challenging, having major junk food cravings. Since then I've seen my food cravings toward junk food decrease dramatically and my taste toward healthier food increase. is a great place to review some of the nutrition principles that helps with fasting in general.

Fasting to gain weight and health

Great article and good explanation on how fasting does what it does. I conducted my first fast after enduring a very frustrating four years of ill health after living in a third world country. I was very sick with chronic fatigue, brain fog, was quite thin and couldn't work. I had no energy no matter what I ate, so after reading a book on fasting I decided to stop eating and try to heal my body. The fast lasted 4 weeks (28 days) when all I did was drink water and grapefruit juice, which kept my bowels moving out the toxins. I had thought I was going to go longer, but at the end of the four weeks my head cleared up and I felt the energy coming back into my body so I decided I could stop. At the time I had no money and was living alone in a small rented camper in the middle of a farmer's apple orchard. I didn't have a lot of options and doctors couldn't figure out what was wrong and told me that there was nothing they could do for me. Following the fast I began to gain weight, got a decent job and got my life back from a miserable and seemingly hopeless situation.

I find the quote on

I find the quote on "under-nutrition without malnutrition" quite interesting. It certainly ties in with many religious beliefs.

I wish people would look to such proven and healthy practices as fasting for weight loss, instead of dangerous and unhealthy pills that don't even work.

Serendip Visitor's picture

The pills definitely don't work

Yes, those ephedrine pills were a disaster for me. I was hooked on them for years and just got fatter. They also do much damage to the digestive system. When under stress the body releases adrenaline. The adrenaline has many effects on the body such as raising blood pressure but another effect is that it shuts down the peristaltic activity of the digestive system. Normally adrenaline is not released continuously but when one takes the pills for energy then one does take them continuously. Ephedrine is a synthetic form of adrenaline and it has the same effects on the body.This means the foodstuffs/waste sit and rot and this damages the colon and intestine.

I meditate daily n do ALOT of walking so my reasons of fasting is just peace, health n loss of weight!

How to start

I feel the best way to start a fasting program is to do it gradually in stages. I initially did one day, then 3, and then worked my way up to 14days over the period of a year and some change. My next goal is 21 days (on day 5 of that now). Sometimes you may fail. I broke my fast a couple times during that period. I find it gets easier and easier to initiate the more times you have done it. It seems as though your body conditions itself for the fast.

The first time I went on a multi-day fast (4 days) the second day was murder!! You know things are bad when you start fantasizing/dreaming about food!! I love to cook and I would look up food and recipies on the internet. It was a really rough but I made it through. The next day forward, I was fine. The desire was never that acute again. I also notice the food I eat prior to the fast makes a big difference in my body’s reaction to going on the fast. I am sure it will be different for everyone.
In my case, I notice eating sweet potatoes, greens, w/a small serving of protein for 2-3 days prior to the fast made entering it much easier as opposed to a typical high protein, carb, and fat diet. Again, I went through periodic rough periods, e.g. when at work they ordered pizza and subs for my office over an entire week!! (I will have to admit, that I got two slices and froze them to eat later when I was off my fast).

You also need to plan on coming off the fast and in many ways this is more important and can be more dangerous than the fast itself. For several days after breaking the fast, I only eat this all fruit sauce (like applesauce but w/bananas or mango etc.) and/or watermelon. When I completed my 14day fast, I was on this high water content food for several days and at the last minute had to take a client out to dinner. I tried to moderate my food intake but ate some fried chicken tenders, seafood dip for appetizer, fries and coleslaw. Big mistake, I managed to make it out and get home w/out embarrassing myself but I turned into a gas factory!! I am not kidding when I say this. It was ridiculous. I could have filled a small blimp with the way my system was working! So I know now, not to fool around when it comes to breaking my fast. I also now include probiotics, that I mix into the fruit sauce when I am breaking a fast.

In terms of the benefits, I have noticed a shoulder that I injured playing golf heal very quickly. Obviously weight loss. I usually go through a period of lethargy around day 3 or 4 and it usually comes out of nowhere. After that period, I am good. The first time I went on a fast, I was wasted for several days and felt like I could barely make it, just walking into my office so if you are a first timer, I would make sure you don’t have anything planned and can rest if needed. Now that I have done several fasts, I find starting during a work week is easier for me as I am usually so busy throughout the day (I am in IT), that it is easy to forget about food for awhile. Well that is my 2 cents. Good luck!!

Get into ketosis before you fast and it is easier

I am currently on the third day of a water fast. Before I started the fast I did the Atkins induction diet for two days. By the morning of the first day of the fast the keto stix were reading a moderate level of ketones. Once you are in ketosis hunger is greatly reduced. I still feel a little hunger though, as my digestive system hasn't quite stopped yet. I hope tomorrow it will all be gone. I am doing this as I have been having symptoms of ulcerative colitis or crohns-frequent diarrhea and intense pain as well as the presences of mucous and blood when I go. In fact, there were times when I would just produce mucous. Every morning I felt like I had been kicked in the gut and then knew I had to get to the toilet FAST. Those attacks started occurring throughout the day as well . Those symptoms have all vanished at this point. I actually feel quite good, better than I have in years. Joint and muscle pains that I took for granted were normal have also all vanished. I forgot what it was like to feel healthy and I am liking this.
I have tried to fast before as well, many times, and never made it past the second day. This time was much easier, one reason being that I got off of all caffeine a couple of weeks ago. The caffeine withdrawals were intense, headaches,brain fog, flulike body aches, my calves and knees especially would burn with pain . Right now I feel no pain at all, it's as if I am on a powerful pain killer.In the past I had tried to fast and drink some black coffee. I think the coffee causes swings in blood glucose levels that make fasting impossible when the inevitable crash hits.

Need more ground rules for a safe fast?

Hi,

I would like to fast for the first time ever and was wondering more about the actual ground rules. I've read some people saying they've gone 40-50 days but yet they leave out too much detail. If you give a story, provide everything you did (ate, drank,did, exercise, etc) to help others, otherwise it's a waste of the readers time as we learn nothing from you or your experience.

Was it water only? Did you eat anything (at all)? Did you take vitamins? Can anyone fasting take vitamins (should we not?)? Are we supposed to exercise or be completely relaxed throughout the process? Can we consume heart protection specific vitamins like Omoege3 pills? Can drinking water and tea really be any different then drinking just water alone? Plain naturally decaf tea has no calories, no carbs, no anything really, but is high in antioxidants which seem like they'd help the process, not hinder it!

Why not promote drinking decaf tea with water too?

I really want to start a 14-15 day fast of only water and tea and wish there was more ground rules that are provided on sites like this for beginners. If you provide the benefits, be accurate and provide the specifics!

In response...

I do fasts where I drink mostly water, with some herbal teas for helping rid my intestines of the bulk.. I personally dont take vitamins or Omega 3 etc for the simple reason I want my digestive system to be almost completely in a state of rest and taking any form of solid would interrupt.. I feel it is more of a personal choice whether or not to take supplements. I started fasting slow, working my way from 1 day to 14 days over a span of a few years, and even now dont always do 14 days, some times 3 or 5(mind you I havent fasted in nearly a year). As far as exercise, I refrain from anything strenuous as the first 1-4 days you can be quite exhausted and could injure yourself, walking is ok but I personally do not promote strenuous exercise during a fast.

You need to understand fasting is something very personal for each person, some drink water, some juice, some add tea some dont, It is something you need to try and figure for yourself. Build up your fast dont start with a 14 day fast, if you "break" it you might be harder on yourself, have a sense of failure etc.. start out slowly 1, 3, 5, 7, 12, 14 etc and each fast one time try with tea and supplements and one time try without and see how you feel. Nonetheless, hope this helps a little and good luck..

Serendip Visitor's picture

I agree, supplements don't help a fast

I agree, one wants one's digestive system to completely shut down so taking any supplements or even juices is not a good idea. The complete rest that the digestive system gets enables it to repair itself as well as this eliminates all feelings of hunger.

fasting

i am doing my 2nd 40 day fast at the beginning of 2012. my first was in 09. the first four days are brutle but after that i was fine. i think that may have been the toxins leaving my body. massive headaches and hunger pangs, after day 5 and 6 the physical was all the same, 20 to 40 minutes of hunger 2 times a day then press passed that and you will be fine. of course there is always temptation for food. just find something better to meditate on,( i personally used the scriptures.). after like day 22 i started getting really light headed and began to drink 1 or 2 protein shakes. nothing else just protein powder and almond milk. if i bent over to tie my shoes i would almost pass out, so that was my reasoning for the shakes. i did this fast for spiritual reasons and i know GOD took pleasure in my effort. i lost 40 pounds or more but the well being out weighed the physical trial. you will be fine, take into consideration any meds you may be on and please consult your physician, enjoy

candida infection while pregnant

A white coating on the tongue indicates nothing more than general bacterial growth in the mouth -- very normal. This normal growth may contain candida, but this is no indication that there is an overgrowth of this fungus. A fairly accurate and simple test is to spit into a glass of water. If you see "strings" in the water after about 15 minutes, you probably have an overgrowth of candida. If you leave the glass of water for more than an hour, there will be bacterial and fungal growth in the water no matter what so the results need to be observed fairly quickly.

An excellent book on fasting

An excellent book on fasting that was written in the 60's is "Therapeutic Fasting" by Arnold De Vries. You can buy a used copy on Amazon. It covers forms of fasting, history of fasting, safety, efficiency and symptoms of the fast, psychological reactions to fasting and how to properly break the fast.

If you want to have the most health benefits from fasting (ie, ridding your body of disease, tumors, toxins, pathogens, etc.) then you should go on a straight water fast - no teas, honey, fruit juice, vegetable broths, spirulina, lemon juice, etc.

By the way Roxanne, the author of this book states that your tongue will be coated the whole time you are fasting which is a sign that toxins and other pathogens are being released. At some point during the fast (it could be up to 40 days or more - less for some more for others) your tongue will clear up and your natural hunger will return and that is when your body has completed healing itself. If you continue beyond this point you risk putting your body into starvation mode where it will start breaking down it's own muscle and organ tissue to survive. But prior to this point there is no need to worry about starvation. Your body is in a state of ketosis and is burning it's adipose (fat) tissue for energy. People with very little fat obviously will be done with a fast sooner than someone with more fat to burn.

My husband and I are starting our water fast this week and are hoping to make it to the completion of the fast, however long it takes. Per the above book, great care must be taken in ending a fast especially of this length. People have actually died from breaking a fast improperly (the book references a guy who ate a beef sandwich after a 40 day water fast and died due to the food getting impacted in his gut). Without going into too much detail a basic rule of thumb is for every 4 to 6 days of a water fast, do one day of a juice diet. So if you water fasted for 30 days, break the fast with 5 days of fruit and veggie juice. Swill it around in your mouth before drinking it to get the enzymes activated to help with digestion. After the juice diet incorporate raw fruits and vegetables starting with small meals and slowly transitioning to larger meals, always remembering to chew the food well. Best wishes if you decide to try the water fast!

Roxanne's picture

TIP FOR FASTING

Check your tongue daily. When a white coating covers the tongue, you should end your fast. It is a warning that you have reached your "fast limit" and the next stage is starvation, a stage you never want to enter.

Dr. Guest457's picture

This is the dumbest thing I

This is the dumbest thing I have ever heard. Having a white coating on the tongue means you have Candida Overgrowth in your body,.

not a good idea

It is not a good idea to take any medication when one fasts. There are many medications that one can not just stop taking without dangerous side effects so I would check this out with your doctor as well as do some of your own research as well.

fasting

Hi I am a 45 yr old male.
I have not eaten any food for the last 35 days and I will not eat for a further 22 days.
I am drinking 3 optislim shakes mixed with water a day, totalling only 600 calories each day. I am a type 2 diabetic and have only been on medication for 10 months.
This drastic diet will reverse my diabetes and I will be off of all medication and living a normal every day life.
I feel younger & more vibrant. My pharmacist asked me how I was feeling after two weeks. I told her I was full of energy and that my primeval human instinct had kicked in and heightening my senses to catch wild game for my survival and dinner.
A friend asked me how you feel in your self, I told her “fantastic and that I feel as if I am galloping bareback and naked on a strong white horse.

I feel really amazing, feeling of rejuvenation .

I'm not sure how you consider

I'm not sure how you consider that fasting?
Healthy, yes, fasting, no!

You're in-taking more then plain water therefor it's not a fast, it's a liquid diet.
I don't think you should tell people you're fasting as it will make them think they can also go
over 55 days without nutrition (but you're yourself!).

Not trying to be mean, just accurate, which it is.

I fast every day for 16 hours

I fast every day for 16 hours (8 of which I sleep) and skip breakfast (to not break the fast :) )

Maintain 7% body fat all year round, train fasted to keep myself biologically young....

This is the ultimate formula to live till 100 and still be able to surf waves.

Fasting for Ramadan

On day 7 of the Ramadan fast. I haven't fasted properly for 2 or 3 years now and it's quite hard, especially here in the northern hemisphere in the summertime. To explain, the fast is no food/no water (and other spiritual regulations)between dawn to dusk, for approx 28 - 30 days. So the fasting period is long - around 18 hours per day without food/drink but you can eat/drink between dusk to dawn. In previous years found the first three days difficult after which I gained a surge of energy, and actually didn't want the month to end! Different this time, a milder headache has returned - maybe cos I took a break for a couple of years. Or maybe getting older. Will see how it goes.

this is not healthy

The ramadan fast is a terribly unhealthy fast. One should always drink water when one is fasting. When you pee and it is a dark yellow to light brown that means you are in danger of kidney failure.

What's with kids and "I'm

What's with kids and "I'm only 13"?? "I'm only 12...but..." posting on forums that aren't for children.

And besides, isn't fasting bad for kiddies? Wouldn't it stunt their growth or something?
