Well, mostly 'free'. Google is tracking everything we watch on KZbin, which they bought a few years ago... and tracks most cell phone owners, our emails, etc - for their profit, with no respect for our rights or privacy. For profit, of course; that's why corporations exist. Thought they freely share our data with government entities, aka 'law enforcement', in most cases without a warrant. So, I remain grateful for the access to the tremendous amount of quality information on KZbin, yet....

PS- Why is our right to privacy so important? Because without privacy there is no freedom. We have been trading our rights for a false sense of security - and for convenience.

But what about what Dr. Fung says?

[@Jefferdaughter]

More on Dr. Fung's clinical experience with fasting - including the finding that most all of his patients actually gain muscle mass: kzbin.info/www/bejne/h5yThmNma76NaNk Of course his patients are advised on how to fast, how long to fast, and are carefully monitored on longer term fasting, but almost anyone can reduce their daily eating window to 8 hours, then 6, or even less. Almost anyone can go from dinner one day to dinner the next occasionally with no problems. Fasting like this was once commonly done in most religions, and still is in many pplaces in the world, as Fung points out. (Ramadan is a little different since they can eat after sunset.) Most anyone can also fast up t about 72 hours with no problems - if they use common sense. Obviously those who are underweight, pregnant, nursing, or have other contraindications should not fast! Longer fasts should be done with medical supervision- if one can find a physician who knows something about fasting...

[@redchakra03]

I have one big interrogation with his fasting point of view, 1/4 pounds lost a day of lean tissu is not equal to 100 % muscle mass, skin is lean tissu, autophagy recycle old cells, which is lean tissu.... And so on, i don't think you catabolyse your heart muscle/other organes first, and all your muscle, if yes your body is so damn stupid, and human wouldn't ever be able to live through 100k years until today ( my English suck sorry)

[@Jefferdaughter]

1:10:30 - Fasting - It is interesting that most of Phinney's concerns and objections to fasting do not relate to the audience member's question, which was about 'fasting' for periods within each day (really reducing the time frame during which we eat each day) and fasting for up to 4 or 5 days. Phinney said he had no problem with restricted eating periods each day. Or fasts up to 48 hours. The rest of his remarks seem to be mostly aimed at Dr. Jason Fung. Yet Fung does not advocate long periods of fasting *except for extreme cases* and *under medical supervision^. Phinney's slide taken from published research shows that the obese are largely protected from the loss of lean body mass during longer fasts - and Fung only uses longer fasts with obese patients. Phinney seems unaware that all lean body mass is not made of muscle. Fung does not advocate fasting for long periods AT ALL for those who are not significantly overweight. Or fasts of any length for those who are already lean, or who may be prone to anorexia nervosa. For those with insulin resistance, which is really an excess of insulin production, Fung does recommending reducing the number of times those people eat each day. And/or very short term fasts - maybe up to a few days. Or every other day. Refeeding syndrome is NOT an issue in these instances. Dr. Fung does not disagree that these patients would benefit from nutritional ketosis through a well-fomulated keto diet - but states that many of his patients are unable to do so, often because of limited finances, and/or these people are already under a lot of stress and find trying to just feed themselves at all challenging enough. Phinney says that two plastic jugs (which leach toxins into whatever they contain) from one of the large discount bulk food chains of olive oil is a cheap way to add healthy fat to the diet, and he believes that olive oil is real. However, it is not 'extra virgin' olive oil, so one must wonder if it was not pressed from the olive, but maybe extracted using chemicals? Regardless, it does take some thinking on how to add a lot more fat to the diet, and get away from the carbohydrate eating habits we have all been trained into. One does not sit down and just eat olive oil. Yes, it can be done, but Dr. Fung has a good point when he says it is faster, easier, and cheaper than re-thinking one's diet. With deep respect for Dr. Phinney, Dr. Jason Fung's videos, books, and website idmprogram.com are all worth checking out.

[@mpoharper]

Jefferdaughter I started dealing with insulin resistance with IF 18 6, and I lost all the weight I needed to but glucose level still prediabetes. So I have started Keto with IF and am making headway on glucose while keeping weight stable. I never really liked eating breakfast so it works for me. I will never go back to 3 meals plus snacks throughout the day. The two together offers an amazing tool to put together something that works for me.

[@stefaniafei]

great reply. plus: nitrogen depletion is NOT losing lean mass, it could come from anywhere, since those are studies from the 50's they are surely incomplete, they didn't know anything about autophagy on those years and a product of the cleaning of the cells is nitrogen. dr phinney is a great researcher but he's biased about fasting, not very well informed and a bit of a snob.

[@kimberlycooper4170]

39:30 -Inflammation - It's not clear whether the ingestion of carbohydrates 'up regulates' an 'inflammatory gene, OR if the ketone bodies 'down regulates' or turns off this gene... but the result is the same. This affects inflammation throughout the body, as well as the G.I. tract. Either way, eliminating sugars and/or starches will reduce or eliminate many of the aches and pains our physicians tell us are due to 'getting older', or old injuries, or whatever. Whether they are unaware of chronic systemic inflammation, or have no idea of the role diet plays in this is unclear. Regardless, it is worth trying dropping all sugar and starch (yes, including fruit) for 2 weeks, to see if it makes a difference. Some people find that the aches they did not even know they had go away!

Regarding the comments on skin conditions: I had eczema, particularly on the insides of my elbows where there were persistent silver-dollar sized lesions. I was using topical steroids for treatment without much success. When I initially started on a ketogenic diet in 2000, the eczema dramatically improved within just 2 weeks, disappearing completely in under 2 months, and has never returned. I have maintained a more or less keto diet from then until now, with only a few short-term lapses. This genuine cure of eczema was a real convincer for me that keto was fundamentally beneficial.

I've read that all these skin issues like eczema psoriasis and even skin cancer are caused by high blood sugar and vegetable oils/trans fats which detox thru the skin. So glad you recovered! Were your lesions like sores that wouldn't heal?

Black coffee is acidic and bitter. We were delighted to find that 'cafe con leche' is not at all bitter, but smooth and delicious. In other words, if enough cream and/or milk is used, no sugar was needed, even when we were first weaning ourselves off sugar. The milk we use if from 100% grassfed Jersey cows, fed certified organic pasture, hay, and fermented hay, and milked once per day, so the butterfat and solids-not-fat are both very high, and relatively low in lactose, though we don't worry about that. The cream is very 'heavy', and is difficult or impossible to pour from the jar. All unpasturized, so the enzymes and naturally occuring benefical diary bacteria are present. We used to drink black coffee, but this is now our favorite way to enjoy coffee. (But we only drink it occasionally, not every day, as we used to.) The 'bullet proof' coffee with coconut oil and/or butter is well known, but some folks may want to try this instead, or as a variation.

His stance on losing lean body mass while in long-term fasting seems to be contrary to more recent studies that show fasting tends to protect lean body mass. And there is anecdotal evidence that someone fasted for more than a year and only started eating when he finally felt hungry, after losing about 80% of his excess fat that he had when he started his fast

Thanks for the details about "keto-flu" I thought it was just an artifact of adaptation due to ramping up of beta-oxidation and did not know about the sodium deficiency effect.

[@Jefferdaughter]

Make sure you also drink enough water, and get enough of the other minerals - especially potassium and magnesium. On salt - unprocessed salt is a much better choice than standard table salt. It is super-heated to ~1,200 F, which changes its molecular structure, has had all the trace and micro-trace minerals removed, and contains chchemicals to prevent it from caking in humid weather. Unprocessed salt - whether Himalayan or Redmond salt from the USA, or Kansas grey, etc - contains valuable trace minerals. It has not been change by high heat in processing, and it tastes so much better!!! Unprocessed salt is also not as dessicating. Those who have had sores on their lips or in their mouths (cold sores, or abrasions, etc) know that salt burns. Natural, unprocessed salt burns very little compared to the processed stuff they put on potato chips, etc - or not at all. Mercola.com has lots of great info on real, unprocessed salt vs the processed stuff. Yup, they have even messed up something as basic as salt!

[@donnaforrest2315]

Another issue with keyto flu is cleaning out your bowels when you fast. It is extremely hard on your body to start a fast and not clean out your bowels. I do a vitamin c flush when I start my fast and it helps my energy and it helps prevent keto flu as well. I also take magnesium and potassium and I put lemon in my water and a pinch of Himalayan sea salt in each large glass of water and I drink a gallon a day.

[@Jefferdaughter]

On salt, common table salt is overly-processed, lacks trace minerals, and contains toxic chemicals added to keep it flowing in humid weather. Sea salts are now polluted, and contain microplastics. So we choose pre-pollution sea salt - Himalayan pink, Redmonds from Utah, or Kansas grey. These natural salts taste so much better than processed salt! And they provide important trace and micro-trace minerals.

[@oliviad6713]

I agree about the salt - it does matter - if not for the extra minerals, definitely for the lack of toxins! Are those 'brands' you are mentioning - i.e Redmonds or Kansas grey? And is there a Himalayan salt brand you recommend (I imagine with it's popularity cheaper imitations are being made. I did read one's salt should be grey, pink, or beige -ish in color, NOT white, as that means it has minerals. I've been using Celtic Sea Salt which is supposed to be pretty good quality. I realize your comment is 2 years old, but someone might chime in :) TY!

[@Francisco-Danconia]

Pre pollution salt... not happening in Utah. Our salt beds are right next to the city, with one of the worst air qualities in the world at times. All that rain has to go somewhere, and the salt is just pulled up outside in giant mountains!

[@JezaGaia]

I disagree on the artificial sweetner part. Some of them like aspartame are really just as dangerous at least for the brain than regular table sweetner. I had depression, anxiety and agoraphobia when I started on my journey to better nutrition. I read a book saying that MSG and aspartame were involved in those conditions and to try removing them to see if it helped, I stopped using them, I was using a tiny amount of aspartam every morning in my coffee, that's all but just stopping that for 2 weeks made my agoraphobia go away and my depression and anxiety were a bit more manageable. Dark thoughts most of all were way less frequent. If I couldn't use safer sweetners like erythritol and stevia I would prefer to use unrefined cane sugar or honey rather than aspartame.

[@drb4074]

Artificial sweeteners are a dicey subject in the LCHF communities. Some people can work with it, some can't. I dropped all sweets completely when I went keto. I see them as having many potential side effects I wasn't interested in interfering with my new lifestyle. And preferred to get the sweet tastes away from my palette, so that I could more easily become accustomed to the more savory foods of keto life. YMMV

[@JezaGaia]

D rB agreed, I just like to share my own experience when I can just in case someone with the same issues can get any benefits from it. That's how I learned about keto after all and that saved my life :)

[@drb4074]

JezaGaia Yeah he kind of touches on that in this video. While there are general guidelines to handle 90% of this style of eating, the remaining parts need to be ironed out on an individual basis. Some things you might be able to use and some you can't.

[@Jefferdaughter]

DrB - In addition to the challenge of weaning ourselves off of sweet flavors, Jeza makes an important point. Aspartame, if I recall correctly, is metabolized to formaldehyde. Mercola.com has excellent articles about artificial sweeteners with references to the medical literature.

Well, I suppose the saltwater drink first thing in the morning before I go riding (still fasting - breakfast after I ride, if I'm hungry) is beginning to make sense. Two large glasses of water, and a salt boost. I don't know how much a gram is, but as though I were salting a meal, just.... in the glass of water.

[@Jefferdaughter]

On salt - we all need it! Table salt is highly processed. It is heated to around 1,200 F which changes the salt. Then chemicals are added so that 'when it rains, it pours'. These chemicals are not beneficial to health. Yup, the corporate industrial food system has messed up even something as basic as salt. Unprocessed salts TASTE better! Once you get used to it, table salt will taste funny, even bad. This is partly due to those added chemicals. The trace and micro-trace minerals - in the proportions present in the ancient seas, and in the healthy bloodstream of animals - adds to the flavor of mined seasalts. Sadly, due to pollution, more sea salts these days are being processed, not simply dried in the sun. However, processing does not remove chemical pollution. Or the microscopic and near microscopic bits of plastic now found in 80%+ of sea salts. We also find that it is less dehydrating to tissues; in other words, if you have chapped lips, or a a cold sore, unprocessed salts to not burn nearly as much, if at all. Natural salts, like Himalayan and Redmond (basically the same thing, but from Utah www.redmondagriculture.com/ ) that are mined from ancient seabed deposits are 'pre-pollution' sea salt. They are not super-heated, and they do not contain added chemicals - which is why Himalayan salt is often sold in a grinder. Even if humidity in the air makes it clump together, you can grind fine particles onto your food. Even sun drying removes some of the beneficial natural trace and micro-trace minerals, so this may be another advantage to mined sea salt.

Almost all awesome data in it. Unfortunately his one opinion on the lean muscle mass loss in fasting does not take into account the selective nature of autophagy. Current theory supports the notion that the body mass reduction is more likely to affect less healthy cells in general. Apoptosis and autophagy is governed by effective cellular internal resource management and by macrophages identifying cells with external protein markers indicating their state. This is current research.

[@Jefferdaughter]

Those wanting more info on the topic can check out Dr. Fung's videos. His associsate talks about their clinical findings - which show an increase in lean muscle mass among the patients fasting under their guidance: kzbin.info/www/bejne/h5yThmNma76NaNk

I was in a season where I was just eating on Saturdays. I knew nothing about the Keto lifestyle but I lost a lot of lean muscle and at sixty now, practicing a Ketogenic lifestyle, I am beginning to repair my body. I have no interest in a long term fast, although I will fast up to twenty hours daily . I don’t do the same time frame each day. Thank you Dr Phinney

[@karlwiley689]

Jason Fung replied to Dr. Phinney's criticisms of fasting (somewhat over-aggressively) in a recent podcast with Jimmy Moore on their new podcast called Fasting Talk (episode 5). His basic claim is that HGH and norepinephrine have protein sparing effects and any protein that is lost is damaged protein/excess skin (he says none of his overweight patients who lose a lot of weight from fasting ever need excess skin removed).

[@bluesdog88]

I would have to agree with Dr Fung on this, not that I'm an expert but I'm thinking the people doing fasting have some health issues that need to be addressed quick smart with some weight loss, I don't think losing some lean muscle would be a huge priority if somebody had 100kg to lose, nothing you can't build later when you are lighter and move around better don't you think?

[@karlwiley689]

Exactly. I think the difference is that Dr. Fung is typically working with obese patients on the verge of type II diabetes, whereas Dr. Phinney, from what I understand, typically works with endurance athletes and people looking to optimize their overall health. If you're highly active, are already at a great weight, and have a well balanced diet, fasting might not be necessary (although I still think it has tremendous benefits and most people should do a long fast once or twice a year). On the flip-side, if you're obese and are looking to rapidly lose weight and re-stabilize your hormones, I think fasting is your best bet. I'm sure Phinney and Fung would agree that Keto and Fasting are simply tools and both have different applications. They need to recognize this and work together rather than sticking in their "camps" and refusing to acknowledge the benefits of both.

[@kaeseistcool]

that is exacly what I am thinking. As an former obese person that is about to become from overweight to "normal" (based on BMI) think that dr fung is far more interesting. I got from Keto to fasting and think both should be done at some point. If Keto work for example me I should learn that my high carb diet was bad for me for a long time. At the same aspect IF and sometime a 24 hour up to 42 hour(18 hours if + 24 hours extra) might help with the addictiove part many obese people have with food and sugar. Including eating when bored ect. Since Dr. Fung talked about his patence alot and that they usually don't gain weight after weight loss might be a part of it.

Comparing the digestion of cattle (whether they are cows, bulls, or steers) to human digestion is... risky. Unlike humans, cattle have four-chambered 'stomachs', including the rumen, which is basically a fermentation vat. Cattle regurgitate the contents of the rumen and chew it again, as these animals are designed to eat forages - grasses, forbs and other vegetation. Cattle, and other ruminants are NOT designed to eat grains, so the guy's question about finely ground grains, aka flour, may be irrelevant. Also, when cattle are fed grain, these are generally truly whole grains (unlike the games processors can play with labeling flour), even if they are coarsely ground to decrease the percent of grains that are passed through the animals undigested. Also, as Phinney alluded, the fiber in grains is mostly or completely removed during processing for human consumption.

41:00 On fiber, and 'whole grain' bread - While truly whole grain bread *may* have some benefits over breads made from finely ground flours that are not really whole grain (as is the case with much of the so-called 'whole grain' bread sold - because it is almost impossible to make a light loaf that rises well, but usually produced a heavy bread that most of those in 'developed' nations are not used to, and/or do not like) may not be as beneficial as we have been led to believe. The ancient Egyptians, for instance, ate bread made from whole, stone ground grain - from ancient grain. It was produced without chemical fertilizers, toxic 'cides', and was not dessicated in the field by being sprayed with herbicides when ripe, as most grains are today - which has led to the alarming rise in glyphosate, and other chemicals, in oatmeal, boxed cereals, and other products made from grain. Yet the ancient Egyptians were chubby, and the men had 'man boobs', which indicates that they had higher levels of estrogen in their bodies than is optimal for men.

Great video. When I eliminated sugar from my diet, after a short time my psoriasis disappeared.

[@muffinman8365]

I wish it cured my psoriasis. The condition is fickle. Congrats though. That's awesome.

[@Jefferdaughter]

Just curious, Muffin, if you also tried eliminating all starch - since starch (bread, pasta, rice, cereals, potatoes, tapioca, etc) is just sugar molecules linked together, and quickly become sugar in our digestion. Alcohol is another substance that, metabolically speaking, is essentially a sugar. Hope you find the right balance of foods for you that helps you feel great, and also restores your skin!

[@takeoffyourblinkers]

@@Jefferdaughter You need to find out what triggers flare ups, and what triggers it generally. Many are inflammation responses, drop the inflammation, psoriasis either goes, or dramatically reduces. If yours isn't related to inflammation then you have a harder road ahead of you.

I eat to satiety, weight train just about every day, never bothered counting calories. I figured I was eating my 1400 daily calories for major weight loss. Just out of curiosity, I counted them up one day I thought was rather indulgent. I was shocked to find that I barely made it to 650 calories.

[@121jgw]

Wow. How was the weight loss like?

[@alexblake5828]

I have a lot of respect for Dr. Phinney, but it is curious that he is so opposed to long term fasting. I'm not a doctor, but my understanding from the current research is that if you are fat adapted, long term fasting does not have a significant negative impact on Resting BMR or lean tissue loss. Its also curious that he cites old articles and says just because they are old doesn't mean they're wrong. That's true, but there is some newer research being done with new measurement techniques that seem to indicate fasting is not as harmful as previously thought.

[@mpy1234567]

How does it not have a significant negative impact on lean tissue loss, which new studies/research?

[@alexblake5828]

Here's one study that seems to indicate lean tissue can be preserved while fasting: ajpendo.physiology.org/content/311/1/E224

[@mpy1234567]

I think the study only says that obese breakdown less protein than lean people. Ketones/Ketosis while fasting is just a way of the body to drastically reduce protein loss over time, bc too much lean mass loss = death. Doesnt mean it can be stopped. It has been shown a lot of times that you lose a siginificant amount, especially during the first days of fasting. Something like 20g-30g after a few days protein loss per day doesnt sound like much...but when you look at how much you have to lift weights and train to gain that amount of muscle...

[@stacyketner]

thats what i was thinking Dr Jason Fung in Canada is treating type 2 diabetes with fasting, they are supervised fast for up to 14 days he's helped thousands of people so exactly how harmful is it?

[@Jefferdaughter]

I share your respect for Phinney, and respectfully disagree with him regarding sensible fasting. In another video e states that 'intermittent fasting' up to 16 hours a day is no problem. And, as Dr. Jason Fung points out, fasts of 24 hours or longer were common to nearly every culture around the world, at least until recently. We noticed that it is much easier to do when fat adapted, and sometimes forget to eat more than one meal a day... or at all! Always while drinking plenty of water, often with pre-pollution mined sea-salt and magnesium in the water, along with a Tbls of raw apple cider vinegar.

[@carrollhoagland1053]

On sweeteners - Aspartame is at least as dangerous as sugar. No synthetic sweetener is 'safe'. Also, those addicted to sugar may need to go 'cold turkey' as sweetness of any kind can perpetuate thee addiction. (Are babies still being given sugar water in hospitals shortly after birth?) Others may find it helpful to wean themselves gradually by enjoying things like small amounts of low-sugar berries (blueberries or blackberries) withe cream, for instance. We recently found that some stevia extracts have no funny aftertaste (which apparently comes from the stems). Most every commercially made desert or 'sweet' is WAAAY too sweet for our taste, anyway, even before we tried low carb living. Now just a few drops of a high-quality stevia extract per serving - at most - makes our homemade ice cream plenty sweet. Stevia is easy to grow in warm climates, or in the summertime in colder areas. 'Fresh squeezed' 100% grassfed cream from Jersey cows, (of Devon, Ayshire, Shorthorn, etc or well-manged goats ) is so delicious that it needs very little sweetening!! It is also wonderful as a savory food - with salt, some onion and/or garlic (even the powders) sprinkled with chives, maybe some bacon crumbles... We don't miss the potato!

[@Jefferdaughter]

On salt - Adding a natural, unprocessed salt to the diet is simple, and cheap. Himalayan and Redmond's natural trace mineral salts have wonderful flavor, contain beneficial trace and micro-trace minerals, and don't 'burn' the way processed salt does. (Yes, industrial/commercial interests have ruined even salt.) These salts are pre-pollution sea salts. Sadly, our oceans are too polluted for me to feel comfortable with sea salt any longer. Also, some sea salts are now also highly processed, super-heated like regular table salt. This exposure to temperatures in the range of 1,400F changes the structure of the salt. Mercola dot com has articles and references on salt, for those who would like more information.

[@Jefferdaughter]

Also, the additives in regular table salt, including ant-caking agents ('When it rains, it pours') are not generally beneficial to health. See Dr. Mercola's website for more info. No affiliation...

Have you tried Epsom salts baths? Epsom salts are Magnesium sulfate. Magnesium is readily absorbed through the skin. Another source of magnesium is dark leafy greens. If added gradually to the diet, these are usually well tolerated.

[@kicknadeadcat]

Himalayan pink salt is Purer then Seasalt. Pink salt is mined in deposits that haven’t been touched or environmentally polluted for a quarter of 1 billion years. It may not be possible to find Pure Seasalt anymore. They have been finding micro plastics in it. Also I tried resistant starch. And my glucose levels go up just the same as any starch.

[@bernadetterocha3693]

I saw a graph of my labs while having not been on Keto and during Keto and off Keto and on it again. The sodium levels ALWAYS dropped to the low normal line when I was on Keto. Because it wasn't below the line, my doctor said it was fine. But it was at the line. The drops were so dramatic that it made me realize I needed to intake my sodium levels so now whenever I do Keto, like now, I'm not afraid of sodium, and I take Magnesium and eat foods high in Potassium. I am hoping the labs I get done in a couple weeks will show promising levels.

The reasons Jason Fung's preaching became reckless too say the least he literally preaches no food, autophagy and how clever every body is and it will not lose muscle mass or affect the heart or create mineral or electrolyte imbalances just don't eat or worry to much about diet if intermittent fasting... he is on podcasts and making zero differention between long term fasting and skipping meals. Let alone eating as you please all calories in one sitting without restraint his words are too often unfounded and not evidence based to the point of negligence trying to make the science a fad and quick fix too his followers.

Salting food cooked at home yes, okay.

When you're fasting and start to burn "lean body mass" it's probably stuff you didn't need at your lower body mass. That's been seen where fasting fat asses don't need to have loose skin removed at the end. The body is kinda smart about that stuff.
