Reply Crepito says: November 18, 2019 at 1:27 pm Please always check if the study did not include any food in ‘fasting’ days. Some use 500kcal. Just focus on hours fasted.

Reply Swiss Lady Driver says: November 18, 2019 at 1:29 pm Maybe not, but it sure feels nice. Reply Phat Vegan says: November 18, 2019 at 1:31 pm Fantastic, As ALWAYS! Reply Swiss Lady Driver says: November 18, 2019 at 1:33 pm So basically, the study you discussed is crap and doesn't provide any meaningful Information? Why bother making the Video? Reply Chris Wesseling says: November 18, 2019 at 1:46 pm Maybe it was the milk… Reply Shari T says: November 18, 2019 at 1:46 pm Thanks for doing the research and posting! Noteworthy how surprisingly little science is out there despite the hype. Reply axiom says: November 18, 2019 at 1:51 pm Perhaps but the stress from doing it may not be worth it 🤷♂️ Reply Darko Kreculj says: November 18, 2019 at 1:51 pm Peter Attia has a good presentation about this. Reply Emily BH says: November 18, 2019 at 1:53 pm Let's see a study that compares the human G.I. tract to primates that shows they are nearly the same and points out the obvious — that humans are not eating a species appropriate diet and have been lied to about what that consists of. Needless to say, I won't hold my breath for that video. Reply Raphael Quaglio says: November 18, 2019 at 1:54 pm Kaku said that rats live longer. We want animal studies! Reply Powernoodle says: November 18, 2019 at 1:55 pm Greger is conjuring up everything he can to poo poo intermittent fasting. Reply Indiegaze says: November 18, 2019 at 1:59 pm So basically – maybe it works and maybe it doesn’t, because the evidence isn’t clear enough and I leave the video being just as confused as I came into it.I wish there were some conclusions or advice on these videos because I after 10 of these fasting videos I still don’t know if you think we should do it or not and in which way. Reply Sadiq Hussain says: November 18, 2019 at 2:01 pm So What did your studies meant?? No Sense.😇😇 Reply Mari says: November 18, 2019 at 2:05 pm Again Japanese don’t fast, but we’re healthier before all sorts of foods came in. 😁 Reply Oliver Barker says: November 18, 2019 at 2:05 pm Can you do a video about Autophagy? Reply jbidwell605 says: November 18, 2019 at 2:10 pm For the people freaking out about being confused – this is just one part of his webinar on fasting. He does go into further depth with fasting and circadian rhythm (early intermittent fasting) as the best proven method. i.e. Only eating breakfast and then a light lunch, then skipping dinner and fasting until the next morning. Reply Cummings Family says: November 18, 2019 at 2:15 pm Got excited for a minute when I saw "human," and thought you were finally going to get to intermittent fastings effect on human growth hormone 🙂 So far none of the studies have actually been on fasted individuals ( ex: milk on fasted days on this study), and the only type of fast is alt-day. We need data on actual fasting intermittently. Reply Rabbit Food Fitness says: November 18, 2019 at 2:21 pm Interesting video, Dr. Greger. From what you have said it does seem that alternate day fasting may help lengthen a person's life. Reply Bobby Thomas says: November 18, 2019 at 2:22 pm I think you would be more relevant a half century ago, like most of your favourite articles. Reply Plant Maven says: November 18, 2019 at 2:43 pm We evolved fasting at times as all animals do. It may have been helpful then, but with supermarkets and restaurants, we got off track. Reply Chuck T. says: November 18, 2019 at 2:48 pm Pretty amazing study given they had MILK on their fasting day, don't you think? Reply jib the world says: November 18, 2019 at 2:49 pm Can you take a look at intermittent fasting for only eating in a window of time each day? thanks! Reply michael onello says: November 18, 2019 at 3:05 pm Interesting but seems inconclusive, to many variables or differences…..Thank you, enjoying all the stuff you're coming out with on fasting!Vegan whole plant based foods on Instagram == mikewakethefoodup Reply Kelly AC says: November 18, 2019 at 3:06 pm Why would you even post this? Why are you avoiding 16-8 hour fasting or 1 meal a day? Reply Rob Williams says: November 18, 2019 at 3:14 pm Wow the last video wasn't enough of a downer? we needed another that was like 'well it might work, but the data is crazy and there's not enough, and the people running it were probably biased…' Reply atila correia says: November 18, 2019 at 3:28 pm So people were eating even on fasting days. lol, what a great study on "fasting". Reply Michael Bradley says: November 18, 2019 at 3:45 pm Could it be possible that fasting is only beneficial for carnivores as they are not putting that bad crap in their mouths, whereas fasting maybe harmful for Vegans as they don't need the dietary restriction?????????????????????????????????? Is that why you get a lot of youtube vegans swapping to carnism after fasting!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! My observational study. Reply mmmgorgeous says: November 18, 2019 at 3:52 pm Yes, it does. Reply Andrés Rubio says: November 18, 2019 at 4:30 pm This video says nothing Reply Benoit Alcide says: November 18, 2019 at 4:38 pm It's a shame that this study was made under the fascist government of Franco. The poor ancients didn¡t have the chance to choice to avoid the study. Perhaps today will be voluntaries for such a test, but surely, the subjets would want to be payed. Reply helenGD says: November 18, 2019 at 5:06 pm Na. Doesn’t mean it’s beneficial. It’s called starving yourself. Reply Neophyte says: November 18, 2019 at 5:42 pm they ate 1600 kcals on average. again this proves less about the alternation than it does about calorie restriction. Reply Home Love says: November 18, 2019 at 5:59 pm 2:30 Dr. Greger doesn't mention the amount of antioxidants on fasting days as a potential explanation for less hospitalisation in the fasting group. Aging has a lot to do with oxidative damage – and eating fruits (= antioxidants) should affect that. Reply Adam Adam says: November 18, 2019 at 6:08 pm Um, the title of this video says ‘intermittent’ fasting, which is not the same as alternate day fasting. So what about intermittent fasting? Is there anything on that, please? Or OMAD? Reply Kuango Seilah says: November 18, 2019 at 6:19 pm Have you ever checked into this story about a man who at age 27 over 350 pounds fasted for over a year on coffee, tea and water? It was supposedly documented by medical doctors it would be interesting to hear your thoughts on this. Here's a link in case you haven't heard of it before; Watch "A Man Who Refused to Eat for 382 Days and Lost 275 Pounds" on YouTubehttps://youtu.be/xJAL5eUBpIQ Reply Captain Planet says: November 18, 2019 at 6:32 pm can you intermittant fasting where you just eat one meal a day. an apple, an ornage and a bannana is all i eat during this one meal Reply Steph Ss says: November 18, 2019 at 6:44 pm Asthma is an inflammatory disease. Most of my inflammation responses are from food…wheat and dairy milk being the top two. It look me until my early 40's to realize this…so, for anyone with asthma, eat plants only, then deal with the animal hair, grass, molds, smoke, fragrances, or anything else you would take an antihistamine for. The biggest culprit is the food we eat. My allergies and asthma now is almost non existent, and I really wish I knew this sooner. Reply Joe Zawinul Reviews and Reactions says: November 18, 2019 at 7:33 pm This trial doesn't seem unethical to try again. Just some people who want to calorie restrict half the time Reply Colin Murphy says: November 18, 2019 at 7:42 pm Please look at intermittent fasting like 16/8 or 20/4 or even 23/1 without alternate day cycles. Haven't heard you mention autophagy once, which is like the main benefit of fasting isn't it? Reply Fernando Fidalgo says: November 18, 2019 at 7:53 pm I was waiting for "…. we may actually never know if such impressive findings can be replicated.. UNTIL NOW.." Reply Jeromy Layne says: November 18, 2019 at 8:41 pm And again the title of the video is click bait. Reply Boleslaw The Brave says: November 18, 2019 at 8:41 pm Why talk about a study with COI and waste our time? Also 900 calories of sugar isn't fasting. You should know that… Reply TheStewieGriffinShow says: November 18, 2019 at 10:26 pm Did anybody learn anything? Reply Fer Ravenclaw says: November 18, 2019 at 11:11 pm Can you talk about how often it's safe to eat processed food?? Reply KinaStar says: November 18, 2019 at 11:24 pm so, I still feel confused about this. I'm on my 30s but want to know if I can go for this to keep my weight in the line since I love eating a high starchy diet. Thanks! Reply Wayne RN says: November 18, 2019 at 11:31 pm Disappointed to see ZDoggMD talk about Vegan nutrition and “bad science” in his video on YouTube, Sure wish Dr. Greger could set him straight. Would love to see a rebuttal or even better an appearance on his talk show. https://youtu.be/ORZ2md-YyZY Reply Raw Thinking says: November 19, 2019 at 1:13 am Dear Dr. Gregor, I have a very important question to ask and would be extremely happy about any form of reply!I recently did a complete DNA/microbiome test, where they tested my gut bacteria and other gut markers. My markers generally speaking pretty good. They found out that my microbiome is dominated by the "Ruminococcus" bacteria. However, it turned out that I am laking some bacteria that I find to be pretty crucial. They categorized by vitamin producing (we are talking about b12 and K) bacteria, which seem to be close to non-existent, or even non-existent in my gut. Regarding B12 it is Propionibacterium, Bacillus, and Lactobacillus that all mark 0.0. Looking at Vitamin K it is Enterobacter, Lactococcus, and Serratia with 0.0. My question is: Are the bacteria essential to build the vitamin. I know B12 is build by bacteria. So what if there is a lack of the bacteria producing B12. Can you counteract it with supplementation? I could send the report too, it's in German though. 😀 I have been plant-based for about 5 years now, 24 years old, 183cm (6"0) and about 93kg. I do strength training so I would say I am overweight, but a body fat percentage of 18% could be true, Christmas is approaching… Reply Chris Namaste says: November 19, 2019 at 2:41 am Where was the "UNTIL NOW"! I feel cheated. Reply JessBisme123 says: November 19, 2019 at 5:06 am I wish these studies were about actual fasts. Lol. Reply Patti Dunford says: November 19, 2019 at 5:56 am Wow! that's so interesting Reply ggzh a Argue With Everyone says: November 19, 2019 at 8:09 am Is it possible that the experimental group ate more fruits since that was one of 2 food groups they could eat on fasting days, and that this lead to a better result?Or that they had better results because they consumed more milk? Reply अष्टावक्रः ashtavakra says: November 19, 2019 at 9:53 am it all depends Reply The Artificial Society says: November 19, 2019 at 10:52 am Starving then binging is not good for health or emotional state. Best to be in a routine of eating very basic same old food. If you start playing games with smoothies, nuts or nut butters, vegan desserts/confections, or sweet fruits, you can easily get into a craving binging scenario. Plain old whole starchy staples and vegetables is the best way with modest fruit. Reply Brescalofrio says: November 19, 2019 at 11:14 am This is calorie restriction Reply Damien Neveu says: November 19, 2019 at 11:32 am The title of the study is literally “alternate day *calorie restriction*”. Why call it “alternate day fasting” ?Again, *not* the same thing. Reply Elizabeth Underwood says: November 19, 2019 at 12:08 pm Have you seen the work of Jason Fung on alternate fasting and diabetes recovery? Reply Skeptical Simmy says: November 19, 2019 at 12:43 pm Ok George R.R. Martin, enough with the cliffhangers already! 😉 Reply Hulagu Kahn says: November 19, 2019 at 1:50 pm Until…….. Reply ____ says: November 19, 2019 at 2:25 pm This channel is so good Reply stephane stephane says: November 19, 2019 at 5:00 pm Taking 900 calories in is not fasting Reply Doug McKeen says: November 19, 2019 at 5:55 pm Dr. Greger, you should make a playlist for convincing people to change their diet! Something I can send people a link to when they ask why I'm vegan Reply David Smith says: November 19, 2019 at 6:34 pm This topic will be restricted / squashed just and treated with careful "tobacco science" by big food and big medicine…. and less healthy things like the meat and cheese KETO diet promoted …. More death and disease = more profit .. Reply Vegan Beast says: November 19, 2019 at 8:06 pm Thought one of the main points of your book was about keeping as active as possible so that you can eat as much calories whole plant foods to flood your body with antioxidants. Seems if you calorie restrict or fast than goes completely against this. Reply I M says: November 19, 2019 at 10:36 pm I was over weight with diabetes and my intestines were literally rotting (chronic diverticulitis). I had a fatty cirrhotic liver. I felt like dying everyday. I started fasting for 24 hrs every other day. I started taking milk thistle, marshmallow root and a 20billion 9 strain probiotic everyday. I eat what I want when I want on my non fasting days. NOTE: by nature your body starts rejecting crappy food and leans towards richer proteins and good fats like avocados. No longer diabetic, no longer cirrhotic, no more diverticulitis flare ups and normal weight….. Reply Kirk Davis says: November 20, 2019 at 2:48 am It does make you live longer. It just seems longer. Reply kannonball says: November 20, 2019 at 8:21 am How about actual long term real fasting? For example, 7 or 10 day Water Fast?
