1. Currently on day four 👌🏽

2. What about intermittent fasting
   That is something i have read is beneficial for longer life and slowed agubg

3. Thanks for this Doc. There’s nothing magical about fasting, and if there’s dangers, people really should be informed. If benefits can be attained with safer means- why would you take the risk?

4. Another fast video

5. You are telling me I have to eat food pretty much every day???

6. I've water fasted for 7 days, but I drank a bottle of electrolyte water once a day.

7. For most people it can be healthy to fast a limited period

8. Did you find the worst cases for fasting? Fasting is very beneficial for the body. Jesus said when you fast not if you fast. Everyone should do it. Except pregnant or breastfeeding women.

9. This is how the Vegetable Police ended up in the hospital after breaking a 21 day fast with a raw egg LOL

10. All of your examples were people who were too stupid to do an extended fasting properly, or were deathly ill to begin with.

    If you fast for extended periods and take electrolytes and supplement with vitamins you will be fine.

    Refer to the fasting fat man channel. He did a 150 fast with no problem this year. And is now about 30 days into another fast. No issue.

    Finally , using papers on starving have no relation to obese people fasting. Obese people do not starve when fasting. They have ample fuel storage to sustain them.

11. Very informative! Thank you.

12. This seems like some questionable science. I have done many water only 2 week fasts over the years. Most Americans are severely malnourished, so it makes sense that fasting would rapidly exacerbate that condition for such people. Also, the usual advice is to rest while fasting which is just bad advice. Lying around for extended periods of time will lead to muscle loss whether you are eating or not. Obviously, you should not engage in activities that result in sweating as the loss of electrolytes could certainly be problematic. I wouldn't advise fasting for more than 2 weeks at a time. There are too many horror stories about that to be worth the risk. For me the benefits have been the slight loss of 10-15 #'s of body fat and to easily reset my diet after the fast. During the course of the year, my habits get corrupted by those around me and I end up over eating and not being nearly active enough. Right now, I am doing less than 20 miles of running a week which is pretty sad.

13. This is classic Dr Greger… Cherry pick a few studies that don't represent the majority of the small community of individuals who fast for health reasons. Using satire to passive-aggressively suggests that people who fast are going to die. Most people who attempt intermittent fasting are healthy individuals who are very health conscious and striving to restrict calories in a reasonable way for longevity. Caloric restriction and longevity are very closely correlated. Vegan or not.

14. And now, WHAT ABOUT AUTOPHAGY, INTERMITTENT FASTING and Nobel Prize ??
    I eat OMA plant based food with ocasionaly very small quantity of fish in 4-5 hours window and have no problems.

15. It is not advised by the experts in this field (Fuhrman, Godhaamer, Klaper, et al) to fast for weight loss. Water only fasting is done for health and healing. Please address those benefits about fasting (of which there are not many studies, but people have been doing it for a millennia). Thanks

16. I fast, but unintentionally. I just get really busy and focused sometimes.

17. As medical supervision during WOF is a must, what testing should we make sure is performed? Is urine analysts enough? mAre blood tests necessary? How soon or often should testing be done? Comas are bad!!

    I know there’s is a center near Montréal (Val Santé) that supervises fasts but it isn’t clear what testing is performed.

18. 1960s studies, WWII references, I guess there's been no new relevant fasting data for over 50 years ?

19. What about juice fasting for 5, 10, 30, 60, or 100 days?

20. ❤️❤️❤️

21. One meal a day is very sustainable. These 7 day starvation people think they've accomplished something but it's really short term. It's not a dick measuring contest.

22. This is great! However, I would really love videos on intermittent fasting (16 – 20 hours a day) for weight loss/health/cells etc vs long term fasts for days. Pleaseeeeeeeeeeeeeeeeeeeeeeee

23. It sure is good to promote eating disorders!

24. What if I told you intermittent fasting was really intermittent eating?

25. The reasons why fasting longer than 24 hours, and particularly three or more days, should only be done under the supervision of a health professional and preferably in a live-in clinic.

26. I don’t think you should conflate deaths from fasting in ghettos, wars, and case studies of fasting deaths from decades ago before people understood electrolyte supplementation and modern day therapeutic fasting. More recent fasting studies have shown adverse events but rarely anything life threatening as you covered in this video. I would like to see fasting compared with gastric bypass for obese patients- I think fasting is likely safer and more effective. Also- a low calorie diet is great but many people find eating very low calorie to make them much hungrier than fasting- the latter is more effective. While I generally appreciate the balance of your videos, the first one was fairly positive, this one was pretty negative and purposefully scary.

27. are these fasting series applicable to the trending Intermittent Fasting? If not, a series about IF would be pretty good.

28. Take a multi vitamin or B-complex or eat nuts or seeds while fasting?

29. Interesting, thank you!

    Vegan whole plant based foods on Instagram == mikewakethefoodup

30. 4:14 isn't refeeding syndrome also one of the reasons immigrant children die

31. I have been a fan of Dr. Greger for years, but this is probably the worst video I have ever seen.
    Dr. Greger is trying to discredit fasting by confusing the subject with prolonged "starvation".
    Quoting decades old literature on "starvation" and then serving it as the side effects of fasting is absurd.
    Fasting is not starvation !!!
    Very disappointed !!!

32. I heard that liver and kidney functions change during fasting. I wonder how this impacts multivitamin consumption during the process? Does the RDI change? Also, I’ve heard that ingesting sodium to taste is recommended in longer fasts, but what about potassium and magnesium?

33. I hope you'll do a series on intermittent fasting which is much more doable and beneficial. I think! Let us know 🙂

34. Thank you. Yes it's good to know these dangers in detail, like the thiamine.

35. INTERMITTENT XD

36. Dr. Greger's videos on Fasting are very disappointing and not to the level of thoroughness that his videos normally provide. Giving minutes to a subject that has been exercised for decades and even centuries was poorly reviewed. His videos are based on fear and risks of "catastrophic" failures of fasting versus the successes which far outweigh the failures. I would suggest that those interested in therapeutic fasting study the subject by reading the books on how to water fast safely and successfully rather than watch Dr. Greger's poorly done videos. Dr. Greger would have been better served by simply saying in 5 seconds, "The(re are) reasons why fasting longer than 24 hours, and particularly three or more days, should only be done under the supervision of a health professional and preferably in a live-in clinic."

37. What is hyponatremia?

38. Kinda misleading title when the focus seems to be "Prolonged Fasting"

39. To everyone asking about IF Intermittent Fasting – check the video's description! it's coming up soon

40. Fantastic research and linear analysis.

41. Shouldn't fasting with vitamin and mineral supplementation prevent refeeding syndrome entirely?

42. I somewhat agree, but I think a 3 day fast is nothing to worry about either. I'm certainly not going to pay a doctor for something that simple. As usual, it has to do with overall health. Get exercise, eat healthy, and a fast won't be a problem. You can get a wrist bp checker and have a good idea of your overall health. Mine cost 20 dollars and talks. For weight loss, I think a one day fast per week, with a healthy diet has been the most effective for me. I didn't try a longer one, but I didn't need to either. That's the fastest I've ever lost weight.

43. Thank you so much for this information Dr. I have been considering fasting as a 'safe' method and followed several people on YouTube who have documented their fasts, so it seemed at first glance to be an acceptable and effective method for weight loss. I have now been educated.

44. Smart people don't fast to lose weight! Smart people fast to become more healthy !

45. Dr. Guido Kroemer on Autophagy, Caloric Restriction Mimetics, Fasting & Protein Acetylation — Dr. Guido Kroemer is a professor at the University of Paris Descartes and an expert in immunology, cancer biology, aging, and autophagy. He is one of the most highly cited authors in the field of cell biology and was the most highly cited cell biologist for the period between 2007 and 2013. Especially notable among his contributions: he was the first to discover that the permeabilization of mitochondrial membranes is a concrete step towards apoptotic cell death. This episode is decidedly focused on autophagy, an important cellular program that is inducible by dietary fasting and has broad implications for aging and cancer. https://www.youtube.com/watch?v=Gm626MgpveI&list=PLJEEAVzHu9KwHf7-8HmTDbYeHEwUFDJvq&index=3 series of interviews on the same topic: Dr. Satchin Panda on Time-Restricted Feeding and Its Effects on Obesity, Muscle Mass & Heart Health https://www.youtube.com/watch?v=-R-eqJDQ2nU&list=PLJEEAVzHu9KwHf7-8HmTDbYeHEwUFDJvq

46. CHECK OUT THE SNAKE DIET! Crazy results! The only way i was able o beat my junk food addiction

47. so, ive been doing this thing where i fast 1 weekend a month for a couple days to help control my micro biome. its been helping because ive lost most of my cravings for junk food and have no problem eating whatever i should be eating. im a little confused based on what he said. in most of the studies they talk about 5+ days, but in one section specifically any fasts over 24 hours should be monitored. should i be concerned about fasting once a month? does anyone have an extra info on this?

48. The faster the fast ends the better.

49. This is the first NutritionalFacts vid that made me suspicious. Too many death threat-type case studies for my comfort.

    Still love ya, NF. Just feel like the deep research is where I'll find better answers on fasting, intermittent or otherwise.

50. She ate 1 egg… and died, Died.
    Low Calorie > No Calorie

51. You are talking about extended fasting lasting several days to weeks.  Agreed that should be done under medical supervision and supplements taken.  I fast one day per week (36 hour period) and have been doing this for 5 years now.  I have no ill effects and in fact can only attest to increased health.  Improved bloods, improved immune system (Ive had two colds in the last 5 years and have recovered very quickly once I caught the colds).  You need to have a serious discussion with Valter Longo regards the aging process, longevity etc. and fasting.  For all your good work I get the distinct impression you cherry pick most of your science articles to suit the agenda you wish to push.  That's not good scientific practice.

52. Hey Doc, but what was the body mass of these patients who died? It makes no sense for lean individual to fast for more than 2 days probably, but if they were big fellas with a lot of fat mass would it still be an issue?

53. A rare disagreement with the good doctor on many points in this video. But thanks for the effort, nevertheless.

54. Dr. Jason Fung‘s studies say otherwise. Prolonged fasting is safer than you think. Unsubbing.

55. For about a year, in my 20s, I pretty much starved myself to lose weight. Ate very little when I did eat- and I did lose weight, but much of it was muscle tissue. I can attest to the fact that starving yourself is no good. I think very limited fasting can be beneficial, maybe a day or two, max- but long term is not healthy.

56. That would explain some of the dementia of Tim Sungazer Shieff… 🤔

57. So long fasts = bad.

    Makes sense, starving yourself for extended periods of time never sounded like a good idea in the first place.

    What about short fasts, half a day, a day, 48 hours?

58. Prolonged fasting may be harmful but IF is very healthy-End of Debate.

59. Hi Dr. Greger. Whats your opinion on the 16/8 method for belly fat loss. I'm a 45 year old female. Other channels prove that it's effective. What about you. Thanks.

60. 17 to 18 hours between lunch and breakfast is what I do almost every day.

61. Fasting longer than 24 hours causes oxidative stress . I realised

62. Probably explains Tim Shieff's brain…

63. Thanks doc.

64. Great information about vitamins and micronutrients! Too often overlooked.

65. Has Dr. Greger supervised fasting patients? Dr. Jason Fung has, and continues to with minimal problems. Even in elderly patients. I'll stick with Fung on this one.

66. Educated audience, cam someone tell me if there is a economics channel equivalent to Nutritionfacts.org?

67. You don't recover from heart failure, you will die of it, fasted or not fasted.

68. What about INTERMITTEND FASTING? (Only eating 1 big meal, and fasting for 22-23 hours)

69. Cannot wait to see intermittent fasting videos :).
    And how about doing exercise in the morning on an empty stomach? I've heard it's good, however, I'd rather to hear this from Dr Greger.

70. I wouldnt want a ghetto physician

71. Oh boy. This one fired up all the right people… 🙂
    All he said was: Take vitamins, when you fast.
    (for more than three days)
    What the morons heard: fasting will kill you for sure.
    😁

72. Great info! I was considering an extend fast. I’m so glad I saw this first

73. Thank you for the video. Can you do one about the fast mimicking diet please ? It’s currently touted by longevity expert Valter Longo as a very effective way to extend healthspan and rejuvenate the body as well as maintaining a healthy weight. The science looks solid but I’m no expert. Thanks!

74. Not sure who's pushing exterme long-term fasting. Most are advocating at best 3-4 days not weeks or months.

75. In your previous videos you were pretty much recommending fasting and praising all it’s benefits…

76. Watch Cole Robertson Snake Diet. Facebook Snake Diet for results.

77. Says the doctor who is terribly unhealthy.

78. Bullshit! I do 40/8 Alternate Day Fasting and it is great!

79. I love facts!

80. This is poorly researched and misleading. I've followed this site for 5 years but I don't think Dr G knows much about fasting. Fasting is not Starvation for one thing. The vid mentions True North, well you should speak with Dr Goldhammer from there, he does fantastic work. Fasting can be a great adjunct to a Whole Food Plant Based diet, particularly for overcomming long term health issues of many kinds. This video does a disservice to a fantastic natural curative and wellness modality.

81. Seems a little biased when you're relying on only the decades old research to make your points. There is a lot of Fasting research from even just the last decade running contrary to many of these ideas and none of it was mentioned at all to give a balanced picture. The truth is that we still don't have a lot of definitive answers to these questions and anyone truly committed to scientific truth should admit that.

82. I think the big problem is the refeeding process and not enough vitamins/minerals. I did a 5 day water fast- very weak, couldn't leave the bed, brain fog, and fainted on day 5. I then ate 2 fries leftover from my husband and threw it all up. I had to go to the hospital. A year later I tried again. 21-day water fast- vitamins, liquid minerals, and electrolyte drink. I felt euphoric, almost high even. It is hard to describe but I never felt that good in my life. I ended the fast with a small piece of watermelon, and continued to eat that for 2 days, then started adding in other soft fruits, soups etc. Lost 36lbs, acne cleared, my hair is shiny and thick and my bowels are now regular. I only gained 5 pounds and I did this fast 5 months ago.

83. Helpful info.

84. Wow. "It was working really well… until the patient died." Errm… they really need to re-examine their definition of "working." A definition that comes out as essentially "The patient died, but at least his corpse was less obese" reveals a horrific set of values and biases.

85. The whole killing people thing…😂😂😂😂😂😂😂

86. So can I go on a prolonged fast if I take multi vitamins?

87. More scare tactics and cherry 🍒 picking studies from a vegtard whose goal is to save the animals.

88. So confused. Hella fit people do intermittent fasting, 16 – 8 splits is the most popular, or sometime 24 – 1… But not sustained starvation for days/weeks. So it's kinda, really freakin' confusing. Is it good or is it not? I highly doubt you can starve yourself for a long time without eating unless you're a prisoner .. soo

89. Interesting, the Seven Day Adventist’s do a 30 day juice fast here in Australia for people with diabetes type 2. They have really good success rates with all sorts of chronic diseases . It is known as the Diabetic Health Clinic. I also did the fast out of interest. However this is not the type of fasting u are referring to I am guessing. Although it was tough to do, nothing but about 4 or more litres of fruit & vegetable juice per day for 30 days.

90. If a little is good, a lot is better, right? Wrong. Fasting has diminishing returns, so once ketosis is reached, and the euphoria wares off, the benefits are over and you need to start eating again.

91. Great insight!

92. Summary:
    Gregor doesn't like fasting so he think nobody should like it.
    To prove his point he brings up irrelevant WWII concentration camp starvation deaths.
    Poor science.

93. Thanks

94. Fast-inating

95. He doesn't even mention autophagy in the process of this either. Autophagy seems to come on faster with a full on water fast, vs small meals.

96. Thank you so very much for taking the time to do research and make these videos. It may take me hours to watch multiple short videos but I am sure that it takes you longer to gather this information.

97. So no?

98. Only in Western Society do we have the luxury of depriving ourselves of food. I also would like info on Intermittent Fasting Doctor Greger if you have it. I can go 12 hours w/o eating with 0 problems but when I exceed that, I get hungrier and tend to over eat. I am older and according to my doctor have 0 metabolism any longer.

99. It's good .

100. it is working well
