Fasting – A History Part I

/, Health and Nutrition/Fasting – A History Part I

Fasting is a time tested and ancient tradition.  It has been used not only for weight loss, but to improve concentration, extend life, prevent Alzheimers, prevent insulin resistance and even reverse the entire aging process.  There is much to talk about here so we begin a new subsection “Fasting”.

There is nothing new, except what has been forgotten – Marie Antoinette

So the forgotten question of weight loss is “When should we eat?” We don’t ignore the question of frequency anywhere else. Falling from a building 1000 feet off the ground once will likely kill us. But is this the same as falling from a 1-foot wall 1000 times? Absolutely not. Yet the total distance fallen is still 1000 feet.

All foods will increase insulin levels to some degree. Eating the proper foods will prevent high levels, but won’t do much to lower levels. Some foods that are better than others, but all foods still increase insulin. The key to prevention of resistance is to periodically sustain very low levels of insulin. If all foods raise insulin, then the only answer is the complete voluntary abstinence of food. The answer we are looking for is, in a word, fasting.

Fasting

The answer to this vexing problem lies not in the latest and greatest diet trend, but in the tried and true. Instead of searching for some exotic, never-before-tried diet miracle, we should focus on ancient healing traditions of the past. The waaaayyyy past. Fasting is one of the most ancient healing traditions in human history. This solution has been practiced by virtually every culture and religion on earth.

Whenever fasting is mentioned, there is always the same eye-rolling response. Starvation? That’s the answer? No. Fasting is completely different beast. Starvation is the involuntary absence of food. It is neither deliberate, nor controlled. Starving people have no idea when and where their next meal will come from. Fasting, on the other hand is the voluntary withholding of food for spiritual, health, or other reasons. It is the difference between suicide and dying of old age. The two terms should never be confused with each other. Fasting may be done for any period of time, from a few hours to months on end. In a sense, fasting is part of everyday life. The term ‘break fast’ is the meal that breaks the fast – which is done daily.

Fasting is one of the most ancient and widespread healing traditions in the world. Hippocrates of Cos (c 460 – c370 BC) is widely considered the father of modern medicine. Among the treatments that he prescribed and championed was the practice of fasting, and the consumption of apple cider vinegar. Hippocrates wrote, “To eat when you are sick, is to feed your illness”. The ancient Greek writer and historian Plutarch (cAD46 – c AD 120) also echoed these sentiments. He wrote, “Instead of using medicine, better fast today”. Ancient Greek thinkers Plato and his student Aristotle were also staunch supporters of fasting.

The ancient Greeks believed that medical treatment could be observed from nature. Humans, like most animals, do not eat when they become sick. For this reason, fasting has been called the ‘physician within’. This fasting ‘instinct’ that makes dogs, cats and humans anorexic when sick. This sensation is certainly familiar to everybody. Consider the last time you were sick with the flu. Probably the last thing you wanted to do was eat. So, fasting seems to be a universal human instinct to multiple forms of illnesses. Thus fasting is ingrained into human heritage, and as old as mankind itself.foodcoma

The ancient Greeks believed that fasting improves cognitive abilities. Think about the last time you ate a huge Thanksgiving meal. Did you feel more energetic and mentally alert afterwards? Or, instead did you feel sleepy and a little dopey? More likely the latter. Blood is shunted to your digestive system to cope with the huge influx of food, leaving less blood going to the brain. Result – food coma.

Other intellectual giants were also great proponents of fasting. Philip Paracelsus, the founder of toxicology and one of three fathers of modern Western medicine (along with Hippocrates and Galen) wrote, “Fasting is the greatest remedy – the physician within”. Benjamin Franklin (1706-1790), one of America’s founding fathers and renowned for wide knowledge in many areas once wrote of fasting “The best of all medicines is resting and fasting”.

Fasting for spiritual purposes is widely practiced, and remains part of virtually every major religion in the world. Jesus Christ, Buddha and the prophet Muhammed all shared a common belief in the healing power of fasting. In spiritual terms, it is often called cleansing or purification, but practically, it amounts to the same thing. The practice of fasting developed independently among different religions and cultures, not as something that was harmful, but something that was deeply, intrinsically beneficial to the human body and spirit. In Buddhism, food is often consumed only in the morning, and followers fast from noon until the next morning daily. In addition to this, there may be various water-only fasts for days or weeks on end. Greek Orthodox Christians may follow various fasts over 180-200 days of the year. Dr. Ancel Keys often considered Crete the poster child of the healthy Mediterranean diet. However, there was a critically important factor that he completely dismissed. Most of the population of Crete followed the Greek Orthodox tradition of fasting.

Muslims fast from sunrise to sunset during the holy month of Ramadan. The prophet Muhammad also encouraged fasting on Mondays and Thursdays of every week. Ramadan is the best studied of the fasting periods. It differs from many fasting protocols in that fluids are also forbidden. In addition to fasting, they also undergo a period of mild dehydration. Further, since eating is permitted before sunrise and after sunset, recent studies (27) indicate that daily caloric intake actually rises significantly during this period. Gorging before sunrise and after sunset seems to negate some of the beneficial effect.

So fasting is truly an idea that has withstood the test of time.  Arguable, the three most influential people to have ever lived agreed that fasting is beneficial.  If this was a harmful practice, do you not think we would have figured this out, oh, say 1000 years ago?

There are certainly people who don’t want you to fast.  There’s this happy fellow….

There’s also this lovely mermaid who doesn’t want you to fast…

 

And don’t forget this lovable Tiger….

So the question comes down to this.  To fast or not to fast. With regards to your own health, who would you trust?

After viewing Dr fung videos I now fast, in fact I’m less hungry when I fast, and more hungry when I eat which is a bit odd, but it is what it is. The best side of fasting is that it really pulls the weight off you, and thanks to Jason I now know how to diet properly…..

Susan Parker
Guest

It’s not odd Stuart. I do the same. When we fast, blood sugar and insulin are low. I am hyperinsulinemic which means I produce lots of insulin coupled with insulin resistance and do uptake it properly, so eating after not eating for a long time makes me more hungry as well. Chemistry. I am confident this will heal over time with fasting and the ketogenic diet.

Cristi Vlad
Guest

Along the same lines (fasting is not starvation)

Starvation occurs at the end of a long-term water only fasting, when body-fat levels become so depleted that your metabolism starts burning muscle and organ tissues to survive. During fasting the body focuses on healing and repair. When fasting ends and starvation commences, it is the point of no return. Consequently, even the leanest person may be able to water-only fast for a couple of dozens of days without ever going into starvation.

Susan Parker

Good point Cristi.

I am a type 2 diabetic for 22 years. Before finding Dr. Fung’s website and watching YouTube videos, I was up to 50 units of Lantus once a day and 16 units of Novolog after each meal (usually eating twice a day) plus 2g of Metformin a day. I started fasting March 26, 2015 and today I’m off all my insulin and only I’m only taking 2g of Metformin a day. My question is when should I stop taking Metformin or should I just cut my dose down by half. My sugar is running between 110 and 130.

Jim Anderson

I haven’t tried fasting yet, but I have been stretching out the time between meals — basically, not eating until I am truly hungry. That’s almost a bigger change for me than my low-carb, high-fat diet. I’ve always been a “clockwork” eater. I let the clock tell me when I should eat. Now I can see myself trying a fast. I do believe it would give me a sharper mental edge. In my high-carb days, I’d never have considered fasting. The thought of it was almost painful.

Jim, I can report on my own experience. I have done the 24-hour fast a number of times and it is suprisingly easy. The first time, I was a bit afraid of being too hungry or having headeaches, but the day passed easily. I only had a good cup of coffee after getting up (no sugar!), and the day went by pretty fast until it was time again to eat at 6.30 pm. I didn’t even feel the need to calm my hunger with water, tea, or bouillon. My wife has had the same experience. We are pleasantly surprised by… Read more »

I suspect it would be easier to fast if blood glucose and insulin levels were stable.

Erik

I went from 3 meals a day, to 2, and eventually to one. Now my blood sugar seems to be much more stable (I think I was pre-diabetic about 15 years ago). These days, I know that hunger will go away if I wait 30 minutes, and my stability is much greater. I have even missed eating a whole day before because I was distracted (so approx. 48 hours between meals). Bottom line. It can be difficult to change to fewer meals, but once you do, then you have more freedom (I can go from eating multiple times a day… Read more »

I am an American in Crete now. I can assure you that this is NOT a healthy culture even though the food is wonderful. The young are vibrant and healthy, but by middle age folks look quite tired and inflamed and the elderly are very ill, often quite heavy, have shrunk and lost their height, are often bent over, limping, etc. Maybe it was different in the past but not anymore. This is a wheat intensive diet here, all imported. I suspect the historic diet did not include as much bread, but I’m just speculating. We eat beautiful real food… Read more »

May you have many years of a healthy and satisfying life. I am 81 and I have fasted 24 hours at this point. Yesterday was my first fast and today I feel so good and energetic I’m going to continue another 24 hours. I do not have any medical issues that concern me, although the doctors might find something that needed “treating”. I feel confident that I can treat myself. So, with any luck, you may have a lot of years left to live.

Mike
Guest

I am not from Crete, but my heritage is Orthodox. I can assure you that the fasting that is done during the fast is not healthy. A strict Orthodox fast involves no meat (beef, pork, chicken, sometimes no fish) or animal products (eggs, butter, milk, etc..) During the fast, those foods tend to be replaced with lots of grain products (bread, crackers, jam/preserves), fruit, vegetables (depending on the time of year). Salad/lettuce is rarely eaten. My parents still do Orthodox fasts & usually gain weight during the fasts due to all the grain-based carbs.

Christina

My husband’s family is Coptic Orthodox and that’s exactly what I’ve observed too.

erik

Wondering if there is an optimal fasting pattern seen in your IDM program for adherence or compliance and improved insulin sensitivity; e.g. alternate days (24hr food allowed w/ 24 hr. no food only non-calorie liquids), Partial days – food w/in 6 hr. period no food – liquids only for 18hrs / day (24hrs), etc.- the patterns could seemingly be endless. So is there an optimal way to start?

Doug

Thats the million dollar question. It looks like we are on our own to try and determine the ideal protocol. Unfortunately, I found experimenting with different protocols very tiring and more like yo yo dieting to the point where I am ready to give up on this fasting bs

I have been doing the one meal a day /24 hr fast every day for about 5 weeks and am finding that I seem to be hitting a plateau. I am not counting calories during my meal. I am worried that my metabolism is slowing to match the drop in calories of only eating one meal a day. Could this be true? Should I not be doing this everyday? Also, while I am far from my goal, I’m concerned if eating one meal a day every day causes me to stabilize does that mean I will only eat one meal… Read more »

Hi Jason. Great job with these posts. I lost 50lbs going LCHF for over two years. I have reached a stable weight and have managed to stick to the diet easily and without problems. However, I plateaued about 15 lbs higher than I would like to be and stayed their consistently for about a year. All in all, I was happy because I was still relatively lean, muscualar and in pretty good shape. However since reading your posts I have been convinced to try intermittent fasting. So far, I have definitely lost weight and it has not been super difficult,… Read more »

Thank you for your blog; I’m learning a lot about the three components of dietary management (what, how much, when) that I definitely need to address to lose lbs finally (49, female, yo-yo dieter, glucose intolerant with familial history of diabetes). For now a quick question: what is your position on so-called fasting regimes that allow for consumption of up to 20% daily energy needs, usually 400-500 cal. as a “modified” fast (Varady and that shyster English journalist who beat her to press) or “down day”(Johnson)? Is there any use in this, let’s say, limited to a short eating window,… Read more »

Good question, I’m wondering if the doctor is not responding because of the limited scientific data related to your question. If that is the case, maybe, looking at some n=1 data would help. In my limited experience with IF (I’m guessing 50 or 60 days total fasting days), I normally have my coffee or tea with some heavy whipping cream. Also, as a diabetic, I’ve needed to consume a few grapes or raisins to maintain my blood sugar above the normal 83 mg/dl of blood. So, my ‘fasting’ days have always included about 5% to 10% of my normal calories.… Read more »
Cassandra

Makes sense. Will try set that goal for next 24 hr scheduled fast. 20% isn’t doing much for me though it’s only been a week.

MarianeC
Guest

Cassandra and Nate this answers the questions I had. I am wondering about the heavy whipping cream too. It is probably trial and error with it. I am going to try fasting with 2 T total whipping cream in 2 c. coffee/tea today (I am fasting) and see if that works better than just having 0 food for 24 hours.
I think everyone is different and what works for me might not work for you.

kfacwpup
Admin
There are really no head to head studies so I can only give a clinician’s perspective from my own experience. I think that those fasts that allow 20% of cal or 5:2 style diets still work but slower than a full fast with 0 calories. I think that the most efficient fasts are close to 0, but that is not alway feasible for some. However, I think (only my feeling) is that eating 0 calories is easier, especially for extended periods than eating a small amount. I think the body ‘switches’ to burning fat and the 500 calorie/day diet stops… Read more »

Thank you Dr. Fung for this reply. You used to have a resource page that included a sheet of fasting tips, and if I remember correctly you OK’d coffee with small amounts of milk (cream) and bouillion. Is that accurate? I’m trying 24h of 0% today…if you don’t count the HWC in coffee 2x and bone broth 2x. To concur with what you wrote, it does seem that on days that I try to compress eating into a 4-6 hour window it is hard to stop once I begin eating. I’ve contacted your office via the form regarding your distance… Read more »

I have fasted several times and it does indeed stabilize my glucose and insulin levels. I would not wait for that to be corrected to undertake a fast. I once did a 92-day green juice fast, and as a result I was then able to maintain stable levels, as long as I ate consciously. It is not easy to begin, but after a few days you feel better and your appetite diminishes.

Nate

Thanks for the history lesson. I especially liked the part about Crete and the Greek Orthodox Christians. It reminded me of one of my favorite Rumi poems. Rumi wrote the following excerpts in his poem, ‘Fasting’, in the 13th century Turkey, a neighbor of Crete. This translation was by Coleman Barks: “There’s a hidden sweetness in the stomach’s emptiness. We are lutes, no more, no less. If the soundbox is stuffed full of anything, no music. If the brain and the belly are burning clean with fasting, every moment a new song comes out of the fire. The fog clears,… Read more »

i find it takes 3-4 days of fasting for my blood sugar to fall into normal range. I have done one 4 day fast and one 9 day. I wanted to get to 10 days but my blood pressure dropped and I got lightheaded. In a supervised setting a longer fast may be ok, but I was ‘on my own’ with it. For me, fasting for a few hours or even a day or two doesn’t actually acheive anything. I can only lose unwanted weight when water-fasting. Even very low calorie doesn’t shift it.

If the basis of our lifestyle is evolution, then let me repeat, fasting is a fail for women, as it reduces fertility. This has been proven in animal models. Since inability to reproduce is an evolutionary fail, I continue to be confused why LCHF & Paleo people insist on fasting for women. Do you really want your wives to be infertile? Most women want to have children, and as men, I believe your evolutionary success lies in your wife having kids. Jes’ saying. 😀 “In the luteal phase, insulin concentrations increased notably in the fasted group. The number of recovered… Read more »

Actually my experience was the contrary. Losing excess weight helped me get pregnant. And if fasting helps women lose weight, it should be considered beneficial. Before losing all that weight (10kg), it seemed impossible to get pregnant for over 6 years and there was no detectable problems with either my husband or myself. Of course, once pregnant, fasting is not recommended.

Linda Martin-Peoples

Ohhhhh, webgrrl… I am almost 70 years old and 50 pounds overweight. I also have a 48-year-old daughter and a 22-year- old granddaughter, so I’m going to just take my chances on not being able to ‘get pregnant’ on this wonderful WOE… (down 21 pounds and counting! YAY!) I’m not picking on you, sweetie….it’s just that this WOE is a Godsend to so many of us who are no longer in our child-bearing years, or who are not interested in conceiving. The need to properly nourish our bodies during pregnancy goes without saying, of course.

Actually after 4 years of infertility, I completed a 4 day water only fast (I had completed many 24-36 hour fasts before that) in March and conceived our baby in April. I believe cleaning my body played a major role in my ability to finally conceive and as a bonus I had ZERO morning sickness! I just didn’t want someone to see your comment and shy away from fasting. Always do your own research everyone but it worked for me!

hi Robin, Let me make some comments on the type and need for fasting that is being discussed here. It is for those of us who are struggling with insulin resistance or diabetes. I can tell you for sure that for us, not fasting is leading to infertility because of all the problems associated to high insulin levels. I’ve been dealing with infertilit for about 2yrs now and no doctor of all those I consulted was able to find the root cause which is insulin resistance, and just because I’m lean none did ever suspect of insulin. Then in cases… Read more »

I don’t disagree with you – my comment wasn’t really about fasting impact on fertility. I think that the blanket statement and tone of the comment that I replying to was off and frankly, insulting. And that’s what I was responding to, the, “men do you want your wives infertile?” statement. Just a bizarre mindset to bring to the table and insulting to women.

You can simply use shorter periods of fasting, say 16 or 20 hours and if weight drops too much, to increase food during eating window.

I have type 2 diabetes and when I fast, it always raises my blood sugar. Is fasting always recommended? I was just diagnosed a few months ago but had done IF for a while doing a primal diet (Mark Sisson highly recommends IF). Am I doing something wrong or is it possible fasting doesn’t work well for some?

No, this often happens. The increase in growth hormone and adrenalin increase gluconeogensis which increases blood sugar. It is neither good nor bad.

Fasting is only one way of controlling diabetes. It does work for the large majority of people, but not all.

If your blood sugar goes up when you fast, is that something that could change over time with fasting? Will your body correct itself so that it doesn’t happen? Or should you just not fast at all?
