The Ancient Secret of Weight Loss – Fasting Part 8

/, Health and Nutrition/The Ancient Secret of Weight Loss – Fasting Part 8

There really is no upper limit to fasting regimens. Once again, I will add a cautionary note. If you are taking medications or especially if you have diabetes, you need to discuss this with your physician before starting. The blood sugars often come down with fasting regimens, but if you are taking medications, it may come down too low. This is a potentially fatal condition called hypoglycaemia. It often manifests as shaking, sweating and sometimes seizures. Medications often need to be adjusted including blood sugar and blood pressure medications.

Also, if you feel unwell at any point during the fasting, you must stop. You may feel hungry, but you should not feel faint, or unwell or nauseated. This is not normal and you should not attempt to ‘push through’. I am not specifically recommending any fasting regimens, only trying to document various fasting regimens in widespread use.

The world record for fasting is 382 days. This was a 27 year old man in Scotland who fasted in order to lose weight. He weight 456 pounds at the start of the fasting period. During this time, he only took a multi-vitamin, and something called ‘Paladac’ which was vitamin C and yeast. Why on earth anybody decided that eating yeast was that important is really quite beyond me, but hey, this was 1973, when pet rocks and disco was popular, too, so there you go.

He was able to drink as much non-caloric fluids as he wanted. After all, you would only survive less than 3 days without fluids because of significant dehydration. At various periods, he did receive some potassium and sodium supplements, and he was monitored by a physician throughout the fasting period to see if there was any deleterious effects on his health.

Constipation is one of the main problems we see in fasting. The reason seems simple enough. There is very little going into the gut, so little comes out the other end. This is a problem we face routinely in our IDM clinic. With this world record fast, this patient had bowel movements roughly every 37-48 days. What’s important to note is that this is a normal phenomenon and not an abnormal one. You do not need to have a daily bowel movement to feel well. Nevertheless, less than once a month seems kind of extreme.

His weight decreased from 456 to 180 pounds. Even 5 years afterward, he remained at 196 pounds. One of the most persistent concerns about fasting is the effect on electrolytes. You can see from the accompanying graph that blood sugars do go lower, but remain at the lower limit of normal.  There were no episodes of hypoglycaemia. This is, of course, to be expected, since the body will begin the process of gluconeogenesis (making of new glucose) in order to supply the brain and certain other parts that need glucose (renal medulla and red blood cells). Even the brain is mostly using ketones at this point. As previously shown, muscle is not consumed to provide glucose (gluconeogenesis). Instead, the glycerol backbone from triglycerides (fat) is recycled into glucose while the three fatty acid chains are used for fuel by most of the body.

Calcium and phosphorus levels in the blood vary over the fasting duration but generally remain within the normal limits and are virtually unchanged by the end of the fast. The same goes for plasma urea and creatinine, which are widely used measures of kidney function. Sodium, potassium, chloride and bicarbonate were all unchanged and in the normal range. In this study, uric acid remains stable although other studies have shown some increased uric acid.

Serum magnesium levels did decrease in this study. This is consistent with what we see clinically in our clinic as well. It seems to be especially prevalent in diabetics. It is important to realize that 99% of the body’s magnesium is intracellular and not measured by blood levels. In this study, researchers took the next step to measure the magnesium content within the cells and the erythrocyte Mg levels remained firmly in the normal range. Nevertheless, we often supplement with magnesium to be on the safe side.

The rate of weight loss was 0.72 pounds per day averaged over the entire 382 days. Other studies of fasting over 200 days had shown similar rates of weight loss (from 0.41 to 0.67 pounds per day) for periods of 210, 236, 249 and 256 days. This average of 0.565 ((0.41 + 0.72)/2) is actually quite interesting.

We assume that one pound of fat is 3500 calories. This is a widely quoted figure, but not especially accurate. If we assume that one eats 2000 calories per day, then we would expect 2000/3500 = 0.57 pounds weight loss per day, which is fairly close to that number actually seen. So, for a patient with 100 pounds of fat to lose, you might expect that it would take roughly 200 days to lose it all. 200 days! I don’t generally subscribe to calorie theory for the reason the Caloric Reduction results in reduced Caloric Expenditure. In other words, decreasing Calories In decreases Calories Out resulting in a plateau of weight loss efforts.

However, in the case of straight-on fasting, the caloric theory holds as promised, resulting in a weight loss very close to that predicted if Caloric Expenditure stays stable. In other words – metabolism does not decrease in fasting. A prolonged caloric reduction, on the other hand, is shown to decrease metabolism.

The Ancient Secret

I’ve sometimes called Intermittent Fasting the ‘Ancient Secret’ of weight loss. Why do I resort to such Dr. Oz-like hyperbole? Well, because it’s true. It is an ancient technique of weight loss – dating at to the time of the ancient Greeks over 2. So, if you want to talk about time-tested practices, nothing beats fasting. Consider that LowCarb diets such as endorsed by William Banting also have a long history but only dating from the mid 1800’s. Obesity was quite rare in the time of Jesus Christ, so fasting was used as a method of preserving good health and improving mental clarity.

But why is fasting a ‘secret’? Well, because the nutritional authorities have spent the last 30 years convincing us that we need to eat more to lose weight. We’ve all heard these lies.

You must always eat breakfast within one minute of getting out of bed.

 

You must eat snacks constantly, all day long or else you’ll be consumed by hunger and stuff your face with Krispy Kreme donuts.

 

You should eat 6-7 meals a day or else you’ll be consumed by hunger and stuff your face with Krispy Kreme donuts.

 

You should eat a bedtime snack or else you’ll be hungry while asleep and then stuff your face with Krispy Kreme donuts when you wake up.

 

 

You must never, ever miss a meal, otherwise you’ll be consumed by hunger and stuff your face with Krispy Kreme donut.

 

If you miss a single meal, you’ll develop eating disorders like anorexia.

This last one must be one of the most idiotic myths out there. Fasting is not, like, exactly fun. It’s a hell of a long way from morbid obesity to anorexia. Furthermore, anorexia is a psychologic disorder of body image. Fasting does not lead to anorexia any more than washing your hands leads to obsessive compulsive disorder. But these lies persist.BeatAnorexia

Nevertheless, because of all the worries, you can rest assured that there are studies that show that intermittent fasting does not lead to eating disorders.

Sadly, the public at large has bought into these lies. You can see that from 1977, the vast majority of people ate 3 times a day. By 2003, most people were eating 5-6 times per day. This weight loss advice was as useful as a third nostril.

Much of this increase in eating opportunity is likely to have been funded by Big Food. They want to sell more food. It’s easier to sell more food if people are eating more frequently. So, in order to do that, they needed to make sure that you didn’t ever miss a single meal.

So here’s the bottom line.

Can you fast? Yes – literally millions of people around the world for thousands of years have done it.

Is it unhealthy? No. In fact, it has enormous health benefits, that we have not even touched upon yet.

Will you lose weight? Here is the crazy thing. People have been convinced that fasting will make them gain weight (the bogeyman – starvation mode). OK, Einstein – if you don’t eat anything for 2 weeks, do you think you will lose weight? Of course.

Is it difficult? Not really. Millions of people do it. But it’s not exactly fun, either.

So fasting is effective, simple (one main rule – don’t eat), flexible (lots of different regimens), practical (saves time and money), and virtually guaranteed to work. So why don’t people support it? Because nobody makes money off you when you fast. Only when you buy crazy things like meal replacement shakes. Nobody wants to you to find out the Ancient Secret of Weight Loss.

Thanks so much for your posts, Dr. Fung. They’re always helpful and illuminating. I noticed that, on your website, one fasting regimen you recommend is 24 hours every other day. Is there any harm in doing 24 hours every day–i.e., eating one meal a day at roughly the same time every day? I find that it’s easier for me to do the same thing every day than to change things up. Thanks. Jane Dr. Jason Fung: That is a style similar to the ‘Warrior’ diet. If it works for you, that’s great. For some, they notice a plateau quickly and… Read more »

Hi Dr Fung,
Will a daily 24 hour fast slow the metabolism? Its much easier for me to do a daily 24 hour fast than only few days in a week. But I definitely do not want to slow my metabolism.
However, I’m still unable to fast beyond 24 hrs and I start to get headaches or tiredness or dizziness after 22-23 hours. And hence I begin eating again. I’m not on any kind of medication.

Hello Sarah!.

No it wont. On the contrary it will increase your metabolism due to a hormone called Noradrenaline.

THANK YOU, THANK YOU, THANK YOU for this post!!!!
I have had so much grief slung at me from so many people over the years about how “unhealthy” fasting is, and worries over starvation and food disorders like anorexia. Your series on fasting has been so encouraging, confirming what I have come to believe about how healthful fasting has been for me.

Thanks for another encouraging post. I think I pretty well know what to do now to ensure that my type 2 diabetes stays reversed, but I need constant reminders to keep me focused and to ignore the wilful ignorance of all the doctors who insist that carbohydrate is essential because guidelines say it is. I recently abandoned my usual low carb / high fat intermittent fasting during a three week holiday. This is the standard advice from my doctors over many years “Just relax and enjoy yourself. Don’t obsess about diet and exercise. You can put things right when you… Read more »

Yes, it does look like you are proof against anorexia. The fear of anorexia from fasting is disable for people with a fat accumulation problem. I just left a 96+ hour fast, I’m sure the desire to eat was mainly psychological vice physiological.

In a subsequent article Dr. Fung shows that keytones appear after 2 days, so fasting is a fast way to ketosis.

I started doing 5:2, then 4:3 now do 16:8 every day. I still had cravings. I recently started reading “Good Calories, Bad Calories”, by Gary Taubes, and thought I would try the all meat plan. So I eat “breakfast” at 10 am (hard boiled eggs and meat), then at 4, I eat dinner (meat again, and maybe an apple for a little carb/natural sugar). That’s it. No more cravings. I think the theory is the fat and protein in the meat satiate you better than carbs. Sure worked for me! I do have one free day, where I eat whatever… Read more »

Deb,
I eat strictly fresh, unprocessed, uncured meat and eggs, and I do 6:18 IF daily. Once a week I do 1:23. I’ve been eating nothing but meat for 10 straight months. It cured my sugar addiction. Anything that is not meat doesn’t even look like “food” to me anymore and has absolutely no appeal. Best way of eating ever! And I didn’t adopt this way of eating or the IF for weight loss.

You keep saying that no muscle mass is sacrified during a fast. That is simply false. Triglycerides do not provide enough glycerol to cover all the glucose needs, despite ketosis. The figure that keeps coming up in human fasting experiments is 50 grams of protein lost per day. This information is not even hard to find. I don’t understand why you pretend not to know. Also, yes, caloric expenditure does decrease during a prolonged fast. That is also well documented. Now, as to wether there is a larger decrease than what simple body weight reduction would predict (in other words,… Read more »

Valerie, do you have any links to the studies you quote? The only one I could find (that’s quoted in all the “you lose muscle when fasting” articles) for the 50g is a 1976 trial with 6 (!) subjects. In that study they didn’t actually measure body composition; instead they use the “energy-nitrogen balance method”. Even if that method was accurate (is it, Dr. Fung?), it doesn’t actually say that 50g muscle was lost, as not all the protein in the body is muscle (there are a lot of leftovers proteins the connective tissue). The evolutionary implausibility still remains; the… Read more »

There is the Yang study from 1976 (I believe that is the one you found). There is also the large body of work on human starvation from Cahill (1970s). Cahill reports 75 grams of protein loss at the beginning of a fast, and as low as 20 grams per day for very, very obese people after a few weeks of fasting have already elapsed. All human studies I can find (I am googling them, just like you) show protein loss. All rodents studies too, for that matter. You are right about the protein not all coming from muscle. Organs (liver,… Read more »

” From the studies reviewed here, it would appear as though a lower proportion of lean mass is lost in response to intermittent CR (90% weight lost as fat, 10% weight loss as fat free mass) (21–23) when compared to daily CR (75% weight lost as fat, 25% weight loss as fat free mass”

deb, none of the daily CR studies in your link were fasting (i.e. 100% CR). Also, it’s not very clear (or maybe I overlooked it), but “fat-free mass” seems to refer to everthing that isn’t fat, i.e. including water…

After deep adaptation and when serum ketones ( BHB ) rise above serum glucose ( both in mmol/L )
( So for many in the second week )

“” Later, in total starvation, after the gluconeogenic phase and the saline diuresis, weight loss falls to
what one would calculate, 100-200 g of lean tissue and 150-200 g of fat,
for a total of approximately 500 g per day. ”

20grams of protein is still needed and not just for glucose making this = 100 to 200 grams of actual wet muscle

This is a very good study too ” These results confirm that energy demands, which are generated mostly in the citric acid cycle of mitochondria, are relatively constant in the resting state and have precedence over all other body requirements (53). Furthermore, they clearly show that even in the resting state the body must have a continuous supply of amino acids or glucose for oxidation to accompany fatty acid oxidation to maintain functional activity of the citric acid cycle. Summarily, the data suggest that morbidly obese persons subjected to prolonged periods of starvation can die from protein depletion because there… Read more »

50 grams of protein per day is really nothing. If you’re losing fat mass, you need less muscle to carry that fat, so you’re likely just losing unneeded muscle mass. This book:

http://www.amazon.com/Periodic-Fasting-Repair-Younger-Appreciate-ebook/dp/B00VIV8D5Y/ref=sr_1_1?ie=UTF8&qid=1434284845&sr=8-1&keywords=periodic+fasting+vlad+zot

Indicates the amount of protein lost is not great until body fat stores become depleted. I searched through the book on my Kindle, but there are many references to “protein”. I couldn’t immediately find an amount of protein lost.

BobM
Guest

By the way, starvation mode in fasting does not occur for a very long time (according to Vlad’s book anyway), when fat stores are basically depleted.

As for this, “Do you have any data showing that energy expenditure is less affected by prolonged fasting than with slower weight loss?”, Dr. Fung has posts related to this.

cm
Guest

> 50 grams of protein per day is really nothing.

50 grams = 0.11 lbs. So 30 days a month * 4 months of fasting = 13 lbs of muscle mass lost? That’s far from nothing! I just did a 4 month daily intermittent fast, and lost 30 lbs of weight. I sure hope 13 lbs of that were not lean muscle mass (I don’t think so, but who knows?).

Valerie
Guest
I agree 50 grams is not a deal breaker for most of us, but it is far from zero! Why lying about it? And as you said, protein loss can speed up dramatically if fat stores are low. That would be important for lean diabetics. Dr. Jason Fung: Valerie, I appreciate your discussion and comments. However, accusations about lying, and from your previous post that I am knowingly spreading false knowledge is unacceptable. I may make mistakes at times, and if that is the case, will gladly look at any references you provide. At all times, comments must be respectful… Read more »

surely you have come across STARVATION IN MAN, from Cahill, numerous times through your readings.

Dr Fung has already mentioned that one of the main reasons for fasting is Autophagy.
Which is a prioritized breakdown of damaged cells allowing unneeded proteins to be broken down and the amino acids salvaged for the synthesis of new protein. The failure of autophagy is thought to be one of the main reasons for the accumulation of cell damage and aging. I don’t know how they measure the protein loss but I guess that this recycling process does not recoup 100% of the damaged cells it breaks down.

Nutritional yeast is often recommended by alternative practitioners for its amazing health benefits. https://en.wikipedia.org/wiki/Nutritional_yeast My sister rescued a street cat that was quite sickly.

When not fasting I am on a VLCHFK diet. Most of the advice I read regarding breaking fasts recommends eating fruit. I am loath to eat anything sweet or with carbs due to a serious problem with carb addiction. What do you suggest for a no-carb (or extremely low carb) refeeding? Also, why is “refeeding syndrome” not a concern? Dr. Jason Fung: We often recommend breaking a fast with a small meal – a small salad or a handful of nuts.

Dr. Fung – It is with tears in my eyes that I thank you for your work in this area. It took me a long time to put the puzzle together and realize I had become insulin resistant (high BP, high BG, high triglycerides, rapid weight gain, low HDL, family history of diabetes). I went to several doctors over the course of two years. They all offered me separate medications for each “symptom”, but no explanation or solution to the root problem. I eventually self-diagnosed my insulin resistance and in April, went on a high fat low carb diet. I… Read more »

Dr. Fung did you say before that eating low calorie over fasting will make you more hungry and slow metabolism? Why would eating very low calorie in a day make you more hungry than not eating anything at all for a period of time? When I try to eat a LC diet I tend to limit my food intake naturally because I hate meat unless it’s processed and I get very hungry all the time to the point where I cry because the hunger won’t stop no matter how much or little I eat.

Sarah
Guest

Hi Wendy, I know its weird. But not eating anything at all is much easier than eating a little bit of food. For some reason, eating a little bit of food makes you hungrier than not eating anything at all. I suspect its because of the insulin which is needed to digest the little bit of food that you ate. I was amazed when I tried the 24 hour fast and found it much easier to do than eating little bits of food every now and then.

I would revisit low carb. What you’re describing could and likely is transitory. Your gut flora are probably set to carbs and they need to be reset to meat, fat, and vegetables. I follow a LCHF diet, and have increased my fat intake due to the realization that protein causes insulin to spike. I’ve also started intermittent fasting, first skipping breakfast two days per week, then skipping breakfast and lunch two days per week, then one longer period of fasting and skipping breakfast and lunch one day per week. I’ve made it 39 hours so far, as my longest fast.… Read more »

There were no episodes of hypoglycaemia.” Since when is 30 or even 50 mg/100ml normal?

Did you write about orcas you comment on ketone salts and ketone esters to increase blood ketones and reduce BOTH blood glucose and insulin?

Fasting 36 to 40 hours and then a 24 hour fast along with low carb keeps my BS in the 60 to 80 mg/dl range BUT what I have read about ketone salts and esters is of interest and may help those trying to smoothly enter and maintain the benefits of nutritional ketosis and intermittent fasting.

Hi BobM, I honestly don’t think I can do the LCHF diet again. The diarrhea that I experienced was so severe that I just can’t go through that again. The reason I didn’t stop earlier was because at first I thought it was my medicine. I know that Metformin can cause diarrhea. Then my husband thought that it might be the rotisserie chicken that he picked up from the deli. But the diarrhea didn’t stop.

Hi Marie, the other thing you could do is try to add fermented foods to your diet. I’ve added some yoghurt periodically and also sauerkraut. However, I’ve been on low carb many times and never experienced what you experienced.

I too have had stomach problems and headaches during the initial days of low carb diet. And also after my cheating days. Yes, the diarrhea is severe and so are the headaches, they are mostly migraine-like with visual disturbances and nausea. But it usually lasts only 3-4 days. After I’m settled into LCHF, it gets better. I make sure to eat 2-3 spoons of homemade yoghurt as well as a drink of apple cider vinegar with warm water, a pinch or turmeric and a pinch of pepper daily to ease my headaches and digestive problems.

Sarah

I forgot to mention that the 24 hr fast helped to reduce my symptoms tremendously. Though I need to keep up my salt intake and drink a lot of water. I also drink 2 cups of coffee with whole milk (no sugar) and apple cider vinegar drink when on a 24 hr fast

I’m not the best person to comment on this, then, as I never had these symptoms and have been low carbing consistently for 1.5 years. Before that, I would go into and out of a low carb diet and never had these symptoms. I did feel like garbage with first two weeks or so, but it was more of withdrawal symptoms than anything else.

Hi Marie,
I use the turmeric (which contains curcumin) in combination with the black pepper for reducing any kind of inflammation in the body. The body is able to effectively use the curcumin in the turmeric only if there is black pepper too. The apple cider vinegar, however has probiotics esp if it is with the mother of vinegar and this is what helps the gut.

Hi Sarah, Thanks for your explanation. It is very helpful. I see you have your gut issues all sorted out! 🙂 I was told by a specialist that I had sky high inflammation in my body. She didn’t know what was causing it. I guess it really doesn’t matter–inflammation is inflammation. I will have to try what you suggest to reduce it. I have some Turmeric Force (New Chapter) capsules on hand. It does say right on the box “Full-spectrum Turmeric used as an anti-inflammatory to help relieve joint pain, also used as a liver protectant.” So, it looks like… Read more »

Hi Marie,

Have you checked your omega3 and 6 balance? A high omega 6 ratio leads to high inflammation risk in the body (if you consume alot of sunflower oil, peanuts etc).

Marie
Guest

Hi Jennifer,

Oh, Wow! …no, my doctors haven’t checked my omega3 and 6 balance. I do eat peanuts (I wouldn’t say a lot, but I do eat them). A doctor did tell me to go on Omega 3, but that was to lower my cholesterol. And I have been taking Omega 3.6.9 (Flaxseed, Borage and fish oil blend) to try to help my diabetic neuropathy. Golly, I had no idea that an imbalance could lead to inflammation. I will have to look into this further. Thanks for sharing.

Hi Sarah, I went to the health food store and was so surprised that they are now selling the Turmeric with pepper in supplement form. (Thanks to you, my dear Ayurveda friend, I knew about the importance of this combination before the sales clerk told me about it!) 🙂 On the box it says, “Curries, soups and rice dishes become resplendent with turmeric, a golden rhizome from the ginger family. Considered in Ayurveda as the best medicine, turmeric is a strong anti-inflammatory said to heal the whole person.” I was thinking of taking the Apple Cider Vinegar, turmeric and pepper… Read more »

For me, apple cider vinegar initially caused diarrhea. It has prebiotics (which is the stuff that feeds the probiotics, which are the bacteria in your digestive system). I would go slowly with it. When I started intermittent fasting, I stopped apple cider vinegar, as I was afraid to take it on an empty stomach. I’m now restarting taking it, but I’m going to start slow.

Marie
Guest
Hi BobM, I have never heard that Apple Cider Vinegar was a prebiotic before, so I checked this out. I really can’t say for sure since there are articles claiming one or the other. Here in this article “the mother” in apple cider vinegar is called a probiotic. http://www.webmd.com/apple-cider-vinegar-and-health Here apple cider vinegar is called a prebiotic. https://und.edu/student-life/dining/_files/docs/fact-sheets/probiotics.pdf So, who knows? Is it prebiotic or probiotic? Or is it both? In this article, Mercola tells of a medical study where patients were taking two tablespoons before two meals each day. Apparently, it helps to lower blood sugar levels. (I had… Read more »

There was one more thing I wanted to mention. I had read somewhere that when you take Apple Cider Vinegar on a regular basis, you should always rinse your mouth out with water after you take it. Apparently Apple Cider Vinegar can corrode the enamel on your teeth.

BobM
Guest

That’s absolutely true. Acid is bad for teeth. That’s why I’m thinking of taking my vinegar all at once instead of drinking in water.

I think it’s prebiotic, not probiotic:

http://www.livestrong.com/article/508833-is-apple-cider-vinegar-a-probiotic/

Anyway, let us know how it goes. I’ve just started taking apple cider vinegar again. I’ve adding a little to water, although I think I’m going to take a “shot” of it to reduce the chance I get much on my teeth.

Marie

Hi BobM, On the second page of the WebMD link it said, “That blob is known as “the mother,” and it’s full of probiotics and other beneficial bacteria.” See: http://www.webmd.com/apple-cider-vinegar-and-health?page=2 (I think the WebMD link is fairly reliable for the probiotic information. Additionally, the link I sent previously on prebiotics was from The University of North Dakota, which I also think is fairly reliable.) BobM, please read this link above, as there is a warning not to drink your apple cider vinegar straight up. There are also other warnings for diabetics. Anyway, it will take some time to see how… Read more »

I hate to say this, Marie, but I believe WebMD is the worst possible source for any information. Case in point: WebMD’s recommend technique for losing weight is to eat less and exercise more: http://www.webmd.com/diet/lose-weight-fast-how-to-do-it-safely Another one of their pearls of wisdom: “Don’t skip meals.” As a person who just fasted for about 40 hours, and has fasted for as much as three days, this just shows you how ludicrous WebMD is. I can’t believe them for any information. Personally, I don’t see how Apple Cider Vinegar can have probiotics, as it doesn’t have live cultures. Regardless, we’ll agree to… Read more »

Hi BobM, Sorry for my delay in getting back to you. I have been away for the past week and without Internet connection. (…yes!

Hi BobM,

I just thought of something. What about taking your warm water with Apple Cider Vinegar through a straw? I’m trying it right now. You will still get some on your teeth, so you would have to still rinse your mouth with water after you drink the Apple Cider Vinegar, but it might help to minimize any potential damage to your teeth.

Sarah
Guest

Thanks Marie… I’ve always had poor dental health. So I do oil-pulling with coconut oil and brush my teeth every morning after drinking ACV. In the nights, I just brush my teeth after drinking ACV. I just drink the ACV in about 4-5 big sips. Its a little too sour for me to drink in one go….

deirdra
Guest

Dentists recommend waiting 30 minutes after eating or drinking acidic things before you brush your teeth (but DO rinse your teeth right after the acidic drink/meal). The reason is that the acid opens the pores in your teeth/bones and makes them softer and easiest to erode by brushing in those first 30 minutes. I’ve noticed I have less tooth sensitivity when I rinse my teeth with water and wait 30+ minutes before brushing.

Sarah
Guest

That’s something I didnt know.. thanks Deidra… will try that from tonight…

Marie
Guest

Hi Deirdra,

I didn’t know this. I’ve never had a dentist tell me this before, so thank you for sharing this with us.

So, what you are saying is rinse your mouth with water immediately after taking the Apple Cider Vinegar. Then wait 1/2 hour before you brush your teeth.

My sister has so many problems with teeth sensitivity. She had been taking Sensodyne (as recommended by her dentist). But she told me she believes that after years of use, the Sensodyne has affected her taste buds. …that seems like a high price to pay!

Marie
Guest
Hi Sarah, Oh, I hear you… I drink the apple cider vinegar (ACV) as quickly as possible, myself. (Although, I must say, I really enjoy the taste of the turmeric and pepper. I did try the turmeric and pepper in warm water last night (without the ACV) and quite enjoyed it. I was thinking it was like drinking a nice herbal tea. Yes, coconut oil is great for teeth. If I remember correctly, it has antibacterial, antiviral and antifungal properties. I have a different regimen for my teeth. I have used a natural tooth paste that has cinnamon (sometimes I… Read more »

Hi Marie, Thanks for the tips.. Will try them for my teeth… Thanks for for links too… Turmeric and pepper was a revelation to me a couple of years back.

Try reading Wheat Belly if you want to try to eliminate the joint inflammation and pain. The toxic substances in grains worsen arthritis etc. When I completely avoid anything made with grain/flours my hip,leg neck, shoulder,wrist ,hand and back pain disappear very quickly and return even quicker if I touch grain products.

i started a fast immediately. with no preparation, went 44 hours on my first try (just water), and felt AWESOME. had a SINGLE meal (LCHF) and did a 42 hours fast. had a LCHF meal, and did a 2ish hour fast. in all, i ate 7 times in one full week, saturday evening to saturday evening.

that should have read : “a 24-ish hours fast”, following the 42 hour, and there were two meals between the first and second fast

I’ve been drinking tea with cream while fasting. So i may as well not have bothered right?

I have done it wrong.

Dr. Jason Fung: Not at all. A small amount of cream is acceptable on fasting days in our program. While it is technically not a fast, it is a small enough difference to not matter. It improves compliance so we allow cream with coffee and tea during fast days

That is good to know, I felt like I’d been wasting my time and was worried that it would be actually detrimental.

I have done several long (10-30day) fasts, and always have felt great, worked, did my daily walks, just adding a dash or two of salt to my water in the evening and taking potassium & magnesium if cramps began. Normally I lost about a pound a day. I have tremendous belief in the healing power of water-only fasts, but one important point is that when I stopped the fasts my hunger went through the roof even while staying low carb. I think if I ever do another longer fast I would ease off with 32-36 hour IF meals to re-adjust.… Read more »

In the post Dr. Fung states “metabolism does not decrease in fasting. A prolonged caloric reduction, on the other hand, is shown to decrease metabolism.” In parts six & seven, Dr. Fung speaks about 12, 16 and 24 hour fasts where people eat once or twice a day. My question: why is eating once a day (24 hour fast) considered “fasting” and not prolonged caloric reduction? I am concerned, as Sarah above, that eating once per day will slow my metabolism.

Danielle
Guest
I think it is just because eating anything calorific increases insulin levels, even if it is low calories or even if it is protein or fat instead of carbs. When you don’t eat at all then I guess it is a kind of fasting mode and the insulin levels go lower. When insulin is low enough for you to access fat reserves for energy then you have bags of energy and your metabolism isn’t slowed. Hence after 38 hours no food I can’t get to sleep at night and want to exercise or have sex to try and get sleepy.… Read more »

You don not die after going 3 days without fluid unless you are in the middle of the desert. Dr. Sergei Filinov of Russia has written a fascinating book called Dry Medical Fasting and he regularly supervises dry fasts of up to 11 days in length. I did one on my own for 10 days. It was a profound experience. I certainly would never recommend any do a dry fast without first reading his book. But it is absolute possible and has many health benefits.

Sara
Guest

“After all, you would only survive less than 3 days without fluids because of significant dehydration.”

I disagree with this comment. From personal experience I went through 5 days with no water or food (Dry Fasting) and felt fantastic! Plus I know of people who Dry Fasted for up to 11 days.

Dr. Jason Fung: I stand corrected. However, I would absolutely NOT advise Dry Fasting. That, of course, is my own opinion.

I was fine at church. I took 2 tiny pellets of pure licorice during the service but I think that was for my own paranoia than anything else. So I broke a 38hr fast on Sunday afternoon (a lot of food, HFLC 5 course meal over 4+ hours) with no more reported episodes and now it is Monday and I am now 14hrs fasted and settling in for the long haul with my limes and fizzy water.

Numbers for 9.30am Sunday morning (6.5 days fasted). 4.5 and 4.2. Hmmm I here you say, they are great blood sugars/blood ketones. Actually it is 4.5 which is the blood ketones and the 4.2 is the fasting blood sugar!!!!!!!!!!!! Diabetes be gone!!!!!!!!!!!!!

Took 2 paracetamol and went to sleep. Awoke this morning feeling more like myself of late. I definitely feel better fasted. It makes me wonder about just fasting right through to skinny but I need to eat when I see family or they will (needlessly) worry. Tues morning: 18st 8lbs.

Danielle

I was reading around the subject and it seems that water weight can dissipate after a meal sometimes and also that sometimes 2-3 day fasts instead of longer fasts are a good idea. Maybe I am short on phosphorous? I don’t know what to think… So I broke the 46hr fast with (keto) fried cabbage, sausage meat, liver and extra egg yolks. I added lo salt for Potassium and took kelp and magnesium supplements. Will try fasting again tomorrow and see how it goes.

18st 3lbs this morning, after last night’s meal. Just feel bloated and huge and slightly tingly now and again. I am not hungry so am listening to my body and drinking dandelion coffee and fizzy water with lime and lo salt (potassium source). I also took another magnesium malate. I heard malic acid is good for liver flushes but I don’t know whether a liver flush is just a load of nonsense. Anyway I don’t feel worse after eating a load of keto grease last night so I will carry on as if I wasn’t blown up like a balloon.

HI Danielle, I was just reading the beginning of your post (like Mar 22). I do not understand why do you consider burger and fries being a LCHF. Fries are very high in carbs and are prompting an instant insulin response – that says to your body to store all the fat you are eating. I am using KetoDiet App to track carbs and on the computer you can use FatSecret webpage to calculate carb content of your foods. Also be aware that carbs are different with the processing of the food too (boiled potatoes are different then baked potatoes… Read more »

I was out with family??? What else can you buy in a pub??? I had no bread, no desert and the only carb I had was fries. Please read my post carefully. I don’t expect eating evry 24hrs with only one meal with fries to put weight on. It must have caused a surge in my insulin levels and created re-feeding edema.

Surprising but the water went eventually and my weight ended up lower… Read more »
