Mic the Vegan (11 месяцев назад)
While I thought I was going to be boring people such a long video, it appears that the main criticism was not covering more aspects of IF! Some things I cut out where how in many cases IF can change eating behavior to prevent overeating, how fasting increases cortisol (the stress hormone), more on autophagy (yes I pronounced it wrong, just glad I didn't make bigger mistakes), and more on defeminization of females during fasting. At the end of the day, it is just one video so I would like to maybe do a follow up some time that covers more of the effects on the brain, the insulin changes, and perhaps a look at whether those 500 calorie days are enough to trigger the effects of fasting. I do think IF can help a lot of people but that the general drift I get from proponents is that it CAN'T have negative effects which is simply not true. Thanks for watching.

I appreciate you taking it on. I've tried some of the old time naturopath advice like the Dr. Christopher 3 day cleanse and it has many of the good effects you say people are looking for, and though there's no studies done on it there's a great track record with it. 3 days resets the body, pushes it a little further as two days seems quite easy - however there's a big focus on hydration with it, unlike modern trends that could get peeps in big trouble. It saved me from a gallbladder op and I could see it brilliant for parasite cleansing and rehydration and resetting bad habits on over eating...he was 'almost' but not quite vegan :D

I went down to on average 1000. I stopped losing weight. I stopped being able to train as much. I was eating well, too. Using the Daily Dozen from Dr. Gregor and all. It wasn't 1000 cal of crap. Lots of really fat people do these fasts. Totals as low as 500 calories. If it really worked, we'd all have done it because the sad fact is that being fat in this society is that bad. Most of us would starve rather than be social outcasts. 1) Neither of those dudes are that big. Not in weight room terms. They might have abs and be vascular, but that's not strength. 2) 600 is average for grown males who train properly. Not Div 1 athletes, of course because most of those coaches are for shit (so it's a good thing the athletes are naturally gifted) but they could easily get there if they did it right. Real records that powerlifters are dealing with are more like 900, 1000lbs. Patrik Baboumian lifted over 1200 as a vegan. 3) He holds a record in a drug free federation. Which means he's competing against other small guys. Also, drug free means nothing. The reality is that to get to that level you are doing something, at least hgh. Then you stop, so that you test clean. I know people want to down steroids as cheating but it's really not at the elite level. Everyone is looking for an edge. Could he be all natty? Maybe. But don't let the "drug free" part fool you. Technically, Lance Armstrong was drug free too. His version was blood doping which is a complex situation but doesn't involve drugs. I'm natty, too but if you think I'm competing in a drug free federation, you'd be wrong. The records don't mean anything over there. I don't know that he knows he's lying but he'd be a serious outlier worthy of study if it's true and my guess is he won't submit to that sort of study because it isn't.

HI Mic, I follow and love most of your videos. Mostly vegan, I've tried different IF protocols (now on 16:8), including Amen Ra. Please try IF first, too many reports papers won't help you formulate an opinion. IF helps fixing one's health problems for a start. We eat too often, too much in quantity, and too much crap food. So IF gives us a break. We are naturally built to endure starvation. I think varying how often we eat is best, like, breaking the routine. Our body will adapt to IF stress (Hormesis law?) but we need to experiment it over at least 3 month.

"Caloric restriction" in term of wait loss is like talking about "fuel economy" in terms of "vehicles". Without specifics this whole discussion is hugely out of context. And by the way, 500 calories a day is NOT fasting. Fasting is 0 calories. It is much more complicated than simply alternating eating and not eating. It's more of what you eat during feeding and what you don't eat during fasting vs just eating intervals. All and all I wonder how our ancestors survived without supermarkets and double frosted lattes. Amazing. Not having guaranteed three meals a day surely should've lead to total extinction. And yet, we still here.

I watched the BBC documentary where the reporter lowers his IGF-1 with a 4 day fast like you show and then it goes back up after the fast but the documentary doesn't end there... He ends up taking up alternate day fasting and keeps his IGF-1 at half the original levels permanently, loses a shit tonne of weight and improves his cholesterol profile as well.

Hello. Is there a place where one can ease into a plant-based diet guide. I am thinking about it and any advice would be appreciated.
Weightless (2 месяца назад)
How would we have ever survived as a species if our bodies could not tolerate periods of fasting? We are well adapted for periods of fasting, and there is nothing unhealthy or unnatural about it. A few anecdotes and poorly designed research studies do not help clarify the issue either.

I've intermittent fasted since January - only really started seeing results when I calorie counted too. I find being a bit hungry in the morning easy to manage - tends to eaten between 11 and 7. Lost 25 lbs and counting. My lean muscle mass has stayed pretty much the same. I've lost 10% body fat. Recently gone from Vegetarian to Vegan and <3 it.
Foo Ling (2 месяца назад)
I did IF for 3 months and lost 23 pounds, I went from 203 pounds to 180. All I did was push my breakfast back and I had coffee with cream in the morning. I also cut out all sugar, bread, pasta and rice and had buckwheat in place of rice. I chose to stay on it even though I was at my ideal weight because I felt so good. I didn't restrict any calories and ate whatever I wanted other than sugar and refined carbs with the occasional large pizza. It worked for me while calorie restriction did zip.

I've been doing 20/4 for about a month. Ive lost 11 lbs not vegan just whatever kinda diet although am working on being vegan again. I find that i have to make myself eat more often than not. The only time i get hungry is for about 3 days before menstrual cycle. But even then i don't pig out. I have yet to feel ravenous. The only problem i have is the insomnia.

My personal experience, as someone who is very physically active, and that of the mates I train with is that it has produced noticable fat loss. I follow a 16:8 protocol, though often it ends up being 18:6 or even 20:4, and I generally I just listen to my body and break my fast when I feel hungry (which took an adjustment period but now I barely think about it). I eat the same, if not more calories than before, because I effectively still consume 3 meals, just in a shorter eating window. I recently switched to a whole-food, plant-based diet (dig your channel btw :p) and found it to be just as, if not more effective. To be fair, because I put a lot more focus into meal timing and preparation, and avoid snacking between meals to keep insulin levels low, I tend to consume more nutritious meals and make better choices. Another effect that I have noticed is that when I do eat, I can feel a little drowsy for 1-2 hours. This works fine for me though because I break my fast later in the afternoon when I am normally winding down anyway and it allows me to fall asleep much easier as someone who tends to get an early night within 2 hours if eating dinner. I wake up early to train and I find I have more energy and mental clarity for my workouts than before I started fasting, however if I wait too late in my fasting window to train, my energy levels do drop. If I can give two more benefits of fasting for me, it is that I appreciate food (especially simple food) so much more when I do eat, which makes eating healthy very enjoyable, and restricting the time which I am focussed on preparing food to only a few hours a day means that I rarely think about it when I am fasting and can focus better on other tasks. Regardless of whether fasting really increases fat loss or not while maintaining the same caloric intake, the organised nature of it has certainly improved my self-discipline with the quality of food I eat, and has put hunger and cravings into perspective for me. If there is snacky food around or at a get together, but I have already eaten, I find it easier to refrain from indulging and eating just because it's there. Likewise because I am used to ignoring mild sensations of hunger, I find it easier to suppress cravings for crappy food. I feel like it has given me more respected for what I put in my body because I don't eat as often. In conclusion, fasting has certainly worked for me and I have been able to exploit the various effects it has on my body to optimise my daily routine. Do I think it is something EVERYONE should do? No. But I still recommend experimenting with it or at least taking principles such as refraining from snacking throughout the day and not eating after dinner to better manage one's diet. I hope this rather lengthy personal account can give some people some more insight into what intermittent fasting MAY be able to offer as a lifestyle choice.

Eating 500 calories a day is not fasting
Seiashun (2 месяца назад)
I used to do IF without knowing it, since I skipped breakfast a lot and didn't eat till lunch. Somehow I got into the habit of eating breakfast again. But now I'm going back to 16hr fasting and an 8hr window of eating again for a few reasons. Number one being, it's hot and I don't wanna cook that much, so eating 2 times a day (and eating bigger meals those 2 times), saves me a lot of time prepping food and I don't have to cook as much. And two, I have ulcerative colitis and I found that when I'm fasting, my UC gets better. IF is not such a huge change tbh, you don't even think about it after the first week, it just becomes normal. Your body adjusts and you don't get hungry at all until it's time for your first meal. So the people that are worried they're just gonna be starving all the time, as long as you eat enough calories in your eating window, you won't be starving at all. Can't say that for alternate day fasts though.
Oz Fruitsalad (2 месяца назад)
Thanks Mic for this. I was really happy to hear that IF can increase collagen production. I have just started doing it again as I'm tired of waking up feeling tired and not hungry for breakfast, feeling dehydrated and with bad breath, LOL! I'm trying a mild version with a 10 hr window (breakfast and lunch, ending around 3 pm). I'm eating the same calories as I would normally in 3 meals as my goal isn't weight loss. Benefits for me anecdotally have been waking up easier (1 hr earlier on average), feeling hydrated in the morning, less bad breath, sleeping way better, and having a flatter stomach (not due to weight loss, my guess is just less bloating or less inflammation). I would like to point out that this is really similar to some traditional ways of eating where lunch was the main meal and dinner was very light (just some tea and toast, or soup, etc.,). I believe that the body likes consistency so, as long as it knows what to expect I think it could adjust to almost any routine so long as it is predictable. For example, for the first four days of doing this I am hungry at night, but then my body adjusts and the hunger disappears. It has also reduced my problems with reflux and waking in the middle of the night with indigestion.

to me the greatest benefit of IF is that you give your body more time to heal and do its maintenance, which is not being mentioned in this video at all.

I just recently heard about Fasting Mimicking Diet based on Dr Longo's research. Have you done any research on that? I liked the idea of normal plant-based whole foods 25 days followed by 5 day 800 calorie restriction with high nutrient food and cycling through that. I would love to know your thoughts since I am not a medical researcher and it's hard for me to understand if the research is valid.
MediaJewhad (2 месяца назад)
Growth Hormone spikes after about 24 hrs fasting. This does not happen with caloric restriction (CR). IF really works, is easier to adhere to that CR. So regardless of what you eat, IF is a good idea Any yes, Jews were treated well in the work camps until the Allies bombed the supply lines of Germany causing mass starvation, including those in forced labor camps.
Draven Pike (2 месяца назад)
I find that after 13-14 hours of being in a fasted state I start to feel really great (better mood than in a fed state at work) and have lots of energy and hunger pains go away. Ive done some of my own research and I found that the body switches to Ketone Bodies (fat) for energy after 12-14 hours depending on the individual. I personally feel best since I started eating two big meals a day while adding lots of veggies and cutting way down on meats. The long 16-23hr fast is great when you need to skip breakfast for extra sleep before work.. but to do it properly you want to keep your body's salt and potassium levels from being depleted during the fast. Otherwise your body wont uptake as much nutrients when you break the fast. Only way I know to stay fasted and get potassium and salt is to add cream of tartar (biproduct of wine making) which is very high in potassium and some sea salt to your water. Like 1/4 tsp salt and 1 tsp cream of tartar 12 hrs into the fast helps. How you break the fast is most important as the body will latch on to both healthy and damaged nutrients/toxins. Potato chips with damaged highly compressed high heat exposed canola oil, sunflower or safflower oils or sugar filled processed peanut butter are bad examples. A great way to break a fast would be avacados with extra virgin cold pressed olive oul and sea salt. Cruciferous veggies and dark leafy greens. Or some organic beef bone broth with apple cider vinegar and coconut oil. All great options. If you are really into this stuff then check out Thomas Delaur (speaker of six pack abs and celebrity personal trainer). He has some great tips as well.

My girl and I just started intermitting fasting 4 days ago. We found the first couple days to be challenging but feel like were hitting our stride. We eat from 330pm until 600pm everyday. We'll have a snack like a protein bar or a avocado with mineral salt at 330pm, then eat a large high calorie, nutritious, Vegan meal between 500pm and 6pm. Along with Intermitting fasting we also go to bed every night at 930pm and wake up every morning at 530am to go for a 3 mile jog. After our exercise, we drive to a cold river spot about 10 minuets form my house. There we do the Wim Hof method. Once fully charged with oxygen we do 5 to 20 minuets of cold exposer. So Far So Good!

I did IF for 1800 months 7 days a week without fail . I lost muscle size and fluid from my body but not much fat . Eventually my metabolism shut down and I was gaining weight only after eating very little food . It was good for the first two months after that my body went into some kind of starvation mode and slowed right down . I now eat whole plant based diet and I’ve lost over 20 kg and I’m at my usual tennager weight of 72 kg from 92 kg in just a few months , I feel good and my doctor took me off my blood pressure meds , I am going to eat a whole plant based diet with as much fruit as possible for the rest of my life . My I add that I sometimes eat 2 kg of fruit per day as well as vegetables and nuts and seeds and I can’t increase in weight and I eat from morning til night . No meat or dairy .

I do OMAD and over 7 months I went from 200 down to 155 pounds. I feel absolutely amazing in every way possible. More energy, more alert and focused and best of all sex drive is way up. My penis actually looks much bigger lol. Seriously! I fast Monday to Friday and on the weekends I eat relatively normal. I did lose some muscle but at age 53 the trade off is most definitely worth it.

Ok, it lowers testosterone? I had blood work done 3 days and 4 hours into a water fast and the results were out of this world. My testosterone was total 1976 and free testosterone was 556. That's insane and nothing explains why it was so high other than it was from the fasting. I'm also over 40 and I was not blasting steroids so it makes no sense. Maybe there's an explanation like maybe the blood work was inaccurate? Food for thought. Maybe I should do it again and see plus I did not have blood work before the fast but still. Crazy!
Allostasis (3 месяца назад)
Yeah, he ignored the studies that shows increased testosterone from prolonged fasting. It happens because fasting stimulates a big increase in luteinizing hormone, which again increases testosterone production.

Hi! Got to you by seeing the Keto video on FB, on a Keto vegan FB group! I can't tell you how many people ask me or tell me that they're on keto every single day (I'm a health coach) and I am so fucking tired of answering that question or watching people lead themselves down the rabbit whole of yet another fad. But.. to the topic at hand. I've been doing a sort of IF for a while. On weekdays usually 14-15 hours, on weekends 16-20. Typically eating less on weekend, but I don't count calories and don't really give a crap, because I think calorie counting is a bogus system (but again getting off topic here) Overall, I like this style of eating. My cycle has actually improved, but that could be because I'm not really restricting myself, it's more like, how you said it, my eating schedule. I eat a very diverse, mostly raw, mostly locally grown diet with no processed foods. I am one of those people who actually enjoys a whole foods plant based diet and don't eat this way to look a certain way or impress anyone with my flat abs. I do LOVE the fact that I'm not contributing to the fossil fuel problem or water problems of the worlds as meat eaters do, and that no animals are harmed to support my food cravings. Thanks for the great service you provide to the world Mic. One day when I can actually flat out recommend a vegan diet to peeps through my own private practice, I will be sharing your videos with more and more people. In the meantime, will share on FB and with friends

I'm laughing at this video so hard because it's ludicrous xD. Many points covered do not show the complete details. Intermittent fasting is about eating all your food in a day in the shortest time possible, not about STARVING yourself XD. Second, on intermittent fasting you become lean, you don't build huge muscles because the growth hormone will not do the job alone obviously. What you do experience is high bursts of energy, that I can tell from experience. For muscle building the muscles prefer carbs and exercise obviously, what intermittent fasting does is make you lean. Get it together man. Geez! This is why I rarely rely on videos like this because they are so misinformed. I watch for the laughs really 😂
Poached Womb (3 месяца назад)
i feel like it needs to be pointed out, that in the field of nutrition, individual studies are near-worthless, even if they do help to convince viewers when you flash them up on the screen. conclusions in nutrition aren't made based on individual studies; they're made as data accumulates from large numbers of studies into the same phenomena, usually because there are so many variables which cannot be controlled for in each individual study. thus, saying "this study says X, hence X," is highly misleading, and unless you're going to cite multiple studies into the same specific aspect of diet, yielding the same result in each case, you should probably inform your viewers of what i've just pointed out. nutritional science is not like physics or chemistry, where most of the relevant conditions can be controlled. it's far more dependent on induction than either, and conclusions are drawn with far greater caution than the internet, yourself included, would have everyone believe.

I lost 16 kilos in 6 months thanks to IF. I feel great, lowered my cholesterol and left the doctor impress. He was asking me to take statins for life, after he saw the results he said "keep on doing what you are doing". I do not know if it works for everyone, but i would definitely recommend it.
Anne Marie Martin (3 месяца назад)
Thanks for this info!! IF works for me, however, I use it loosely. I tend to fast 14-17 hours from dinner-brunch. And I dont necessarily restrict calories. You know when you go out drinking, and the first time you pee, you "break the dam", and then you're in the bathroom every 10 minutes... lol. Thats how I am with food! I love to eat! So putting breakfast off a couple hours longer, while drinking water and tea, keeps me from over eating and snacking throughout the day. Seriously, if I have a healthy breakfast in the am, instead of being full/done until lunch, I find myself grazing! So thats why I believe IF works for me. Its pretty much my fancy placebo. God bless!!

I do 16:8 during the week but relax at the weekend and have lost a stone in weight and dropped 4 percentage points in fat in 2 months. For me it means I don’t snack in the evening which I think was my problem 😬 too many Bourbon biscuits!

Why do you quote animal experimentation results like if it was OK and even valid data to your analysis? I subscribed to your channel after having read an article on Happycow, but it seems to me that you're not a vegan, just a dude having a strict vegetarian diet.

U certainly cherry pick parts of each study. For example 1. You first cited a study that shows IF does not result reduce oxidative stress, then proceed to cite the the study by Longo and Mattison that the life extension benefit of IF is not certain, while ignoring one of the findings cited in the study is that IF reduces oxidative stress. In addition to that, the paper reported a lot of benefits from IF that you somehow choose not to discuss. 2. You discredit the work of Kristy Varaday due to the fact she is an AF proponent and the author of an AF book. Obviously you did not apply the same standard to the BROAD study. Heck there is even a “Conflict of interest” section in the paper, detailing the authors are shareholders/directors in Plant Based Lifestyle Ltd. 3. The study showing IF does not elevate testosterone. The study also cited significant increase in leg press maximum strength and increase in arm& thigh muscle cross-sectional area (with significant fat loss) except there is no difference between control group. If the normal diet group isn’t gaining muscle either then IF is not the cause of not gaining muscle mass either.

I do IF. The main reason is to induce autophaghy. Secondarily to help reduce caloric intake. I eat mainly vegetables, some fruit, and very little meat. No refined carbs, no grains except for rice, no dairy. I have not noticed any muscle loss. I have noticed an increase in energy and mental clarity. Also i have increased endurance. I do a daily 6-18 and a weekly 5-2 type of IF.

You were comparing it to starvation, but starvation takes days of eating to kick in. You didn't give any evidence that you actually go into starvation
jysix (3 месяца назад)
Just another prove that you can find studies to support what ever you want. Go to Thomas DeLauer and he throws you dead with studies and biochemical explanations that show a ton of benefits of IF. But the biggest problem is just that people are highly individual and studies on skinny people like Mic have no meaning for overweight people with insulin resistance... When being overweight and insulin resistant and maybe on the way to getting diabetic one of the people to listen to is Jason Fung. Because you can lose wight on any diet, but to keep it off you have to change your insulin levels. And there fasting can seemingly be very helpful.

If you can stick to calorie restriction better with Intermittent fasting than regular diets then, go for it. But I'd say if you start feeling good and proud that you're not eating for a long time then I'd suggest to stop. I've had anorexia in the past and even now I still have to watch my behaviors so I don't slip back into that thought pattern.

i do 16/8 IF since 01/06/2017 . went down by around 10% body fat and workout only when fasting. my levels of energy are very high most of the day .i train 3 times a week, still having progress with weight and reps . [i train for several years now] not feeling hungry usually to the last hour of the fast. vegan based diet with no calories restriction. i guess around 2000-2800.blood test are great [lack of vitamin D that's all]feel like its the right way for me !

I wonder if any of these people that put out these studies actually try the protocol. i started doing IF when i was 48, then added Keto a year later. Not only did i lose body fat and gain strength, my lipid panels for the past 2 years were amazing. i do IF everyday, for the past 2 months OMAD. What lead me to IF is when I went to an orthopedic surgeon to discuss why I was unable to perform a body weight squat or lunge without pain in my knees. After some x-rays, i was told that i had severe arthritis and was told that I would eventually need a double knee replacement. The surgeon told me that he could write me a prescription to help with the pain and refer me to a PT, and this could prolong the surgery. I left thinking there had to be a better way. I ran across a research paper on Autophagy and how to promote it. The rest was history. Here is my Journey: https://www.youtube.com/watch?v=nEY6WRaJx0U

I tried the alternate day thing and found it difficult to follow. Then, I just decided adopt an everyday routine where eat all I need in a 4 or 5 hour window....it would be too hard for me to eat all I need in a shorter amount of time. --It turns out to be the easiest routine to follow that I've ever tried and that also allows me to stay at the weight I'm at or to lose weight without feeling deprived.The reason it is easy for me to maintain full control is because I am really full, sometimes a bit too full, when I'm done eating all my body needs by roughly following Dr. Greger's Daily Dozen. If I see that I've gained a couple of pounds, it is simply a matter of cutting down on portion size a little to reverse that gain, especially by reducing the calorie dense ingredients like nuts and seeds and avocados a little. I still end up feeling very full and satisfied, and that feeling lasts for hours....I just drink plenty of water the rest of the day and never feel hungry before bedtime. --I wake up early, drink about a quart of water, also drink a concoction of turmeric powder, matcha tea, fenugreek, and black pepper. Then I go to the gym, drink a small amount of black coffee when I arrive and some more water, then work out for an hour. The spice/ tea/ coffee puts some antioxidants in my system to help with recovery. I start eating when I arrive back home at approximately 7:30 or 8am and finish around noon or 1pm. --It has helped me in a number of additional ways besides having full control of calorie intake...I sleep better with an empty stomach, I have more energy during workouts and throughout the day, and it improves my bowel regularity ...all of those things become an issue for many people my age (65). And, when I come home after exercise, I'm eager to eat and it's like Thanksgiving Day every morning.

What about blood sugar levels? Does that decrease after not eating for a day or two?
Jennifer Levine (3 месяца назад)
The first thing I noticed about that every other day fasting was that on the fasting days, calories were allowed! That's not a fast. The other thing that you didn't go into all that much was that autophagy can help get rid of some of the crap in your body. Like fibroids. Which has become an issue for a lot of women. You also mentioned Dr Amin Ra. I saw that video and what Markus Rothkranz said was that the reason that this guy is able to do this is because he's so clean internally. I myself have found that the cleaner I am the less food I need. The body just becomes more efficient the longer you eat a good clean healthy vegan diet. The theory is that it's not about calories it's about nutrients. If you can get enough nutrients into your body on 1500 calories then you know that's fine. I think that because we live in a society that is obese, yet starving (because of the standard American diet) that we place such a heavy emphasis upon calories. In conclusion, I would like to say that whatever diet you eat, it's an individual thing. I noticed that you had two guests each one who had tried something similar to the Dr Amin Ra regime. One person had good results, the other not so good. (I would also like to say that you look very good. Your skin is 9 shades of amazing!)

I've been doing intermittent fasting for about 7 months and I love it. I fast between 16 and 20 hours per day
SirWilliamSquireVonDutchMire (3 месяца назад)
For a good part of human life on earth people went for longer spans between meals than presently. If people don't get 3 meals a day and lunch is an hour or 2 late they whine and cry about it. Your body gets used to the schedule of eating and we would be just fine limiting ourselves to 2 meals a day and cutting our calories down.

alan fullbrook (4 месяца назад)
All I can say is since stumbling across intermittent fasting I have lost 5 stone, I feel really good and am now looking at a vegan plant based diet diet. All I can say is it’s worked for me. Try it what have you got lose apart from weight. 1st I skipped breakfast and started eating at 11am now I’m on one meal a day at around 5 or6 pm, and have never looked back. It’s been about 2 years now but definitely worth a go!
Brian Kenny (4 месяца назад)
That Amen Ra guy uses a very specific supplement blend you take daily. It makes up for the low calorie. The one hour a day thing is highly disciplined. I can't do it. Takes me two hours and I eat more. Who knows about the claims, but it works for getting cut. No loss of power. I have had tremendous success, anecdotally. Eating disorder? Discipline.
Stuart McGregor (4 месяца назад)
As someone who is looking to lose weight and watched videos on everything from, IF, OMAD, Calorie Restriction, Paleo, Keto, Plant Based etc etc, it seems that EVERY video has research it can point to about its benefits. So, I’m now stressed, eating more and not losing weight because of the utter confusion of it all 😂

I intermittent fasted for two months 16/8, break for one month then back on for four months and lost about 40% of my hair. I am a WFPB vegan. Since I have gone back to eating regularly, My hair has since started to regrow. And my period was all over the place as well. :( lesson learned the hard way. I did loss some weight, however I work out regularly and I’m vegan so I really don’t think it was connected, especially since I am still losing weight eating on a normal schedule.
Proctor Silex (4 месяца назад)
16:8 seems to have helped my problematic digestion. I have much less gas, discomfort, and regurgitation. Previously, I would feel full very easily. Now, I can eat as much or more in eight hours as in an entire day. Only time will tell if this improvement is from the eating pattern. I can also go without eating and not feel horrible (skipping a meal in the past could hit me hard). I feel like I have more energy and can consistently exercise better, which might be more of a result from having less digestive trouble than from having more available energy. I have not seen any other benefits or negatives after a couple of months. It is far from magical and YRMV.

Hi Mic! Love your videos! So informative, and actually based on science and reason.....very refreshing. :)  I have tried IF, and it worked well for me in the context of my goals: improved gut health and a more healthy BMI. I did the 16/8 everyday for a few months, and I feel that the time spent not eating is really good for your gut health. I felt so strongly that I was doing good things for my body that I expanded into some prolonged fasting. Once I became a full-fledged Vegan, however, I had to stop IF b/c it was very hard to get enough calories. I now eat veg/fruit smoothies soon after waking, then more solid foods like rice, beans, grains and other whole foods later in the morning, and it seems to meet my calorie needs and sustains my energy more evenly. That's my experience. I would recommend IF to anyone trying to get some control over their eating habits and at the same time trying to improve things like weight, gut health, cholesterol or BP, etc......things that respond to dietary changes. :)

So what I got from this video is that IF could maybe be helpful for me as a type one diabetic but could also maybe be harmful to me as a woman. I guess I'll just keep eating like normal until more research is available lol

Fasting may not hold all the answers, but with more research at this current date in time, it would be a great if you covered 'time restricted eating'.
