Doctor Mike On Diets: Intermittent Fasting | Diet Review

– I’ve seen your request,
I’ve read your comments so here we go, intermittent fasting. – I am dying to talk to you about this. – I eat for eight hours,
and I fast for 16. – I can feel the difference. – Before we get into the pros and cons, and if you should do it, let’s talk about what
intermittent fasting actually is. Human fasting is not a
new concept by any means. Humans have been doing it for a millennia. Intermittent fasting is just a rebranding of something that we
have already been doing. Our bodies enter a fasting
state every time we’re asleep. Some people do intermittent
fasting and not even know it. I mean, there’s plenty of times where I had a stressful rotation
in medical school, or a difficult job in the hospital, where I didn’t have time to eat breakfast. That’s a form of intermittent fasting and our bodies are totally
capable of handling this. I know what you’re thinking. I don’t want to starve
myself for health benefits. Intermittent fasting is not starving. When you are fasting, your
body is using stored nutrients and stored energy forms in order to make your body continue to function. When you’re starving, you’ve run out of those energy sources and are breaking down
vital tissues like organs to get that same energy. There are many different
ways to go about going on one of these diets and that
not only makes it confusing for you, but that also
makes it very difficult to do research on it to find
out how effective it truly is because if there are
multiple ways to do it, we have to be able to test
each one of those ways. The 16/8 diet which is not eating during 16 hours of the day. Alternate day fasting
where you eat one day, fast the other day. 5:2 where two days of the
week that you’re fasting. There’s no hard and fast rule saying that this is the correct way of doing it. You may be wondering how
is IF beneficial to me? There’s been a lot of
proposed health benefits, many of them have been
proven within animal studies or lab models which is not the same thing as being proven in a human model. But they are very promising. Now, those benefits include
increased mental sharpness, a favorable hormonal profile, weight loss, decreases of inflammation within the body, decreases of certain
diseases within the body. How can IF help you lose weight? You have an increase in growth hormone, a decrease in insulin, and that alone will help you lose weight. Next, because you’re skipping meals or you’re even going days
without eating meals, it is very likely that when
you look throughout the week, you’ll be eating fewer calories. Our thinking is that during
eight hours you’ll eat less than you would if you were
eating during 16 hours. Let’s talk about these
other health benefits. We know that chronic stress
is not good for the body. The body is just not meant to
be chronically stressed out. It’s not meant to have a high heart rate, high blood pressure. Intermittent fasting is really a form acute, short-term, mild stress. This time of acute, short-term stress is really good for the body. What can we use as a metaphor here? Let’s take exercise. Exercise is a form of acute, mild stress. What happens after exercise? We have benefits for the brain, we have benefits for weight loss, we have benefits for disease prevention. Now similarly, when you stress your body through intermittent fasting,
there are some benefits. More autophagy, which is the
removal of cellular waste, more production of neurotropic factors, which protect your brain. And a favorable hormonal profile with increases in human growth
hormone and norepinephrine. Let’s talk about some of
the shortcoming of IF. Primarily, there’s not enough guidance of what you should eat. We don’t know how many calories, we don’t know what foods
to eat on the days or times that you actually are eating. Second, we don’t know
which form of IF is best. Third, there are some side
effects when you are fasting that people do experience:
headaches, mental fog, heartburn, these things do exist,
it’s not totally benign. Four, we don’t know the consequences of following an intermittent
fasting diet long term. Most, if not all, of these studies are done on the short term. If you are eating a very unhealthy diet and then make a change you’re
definitely gonna see a benefit But now does this benefit
still hold up one, two, three, 10 years down the line? We don’t know that yet
when it comes to IF. And five, it’s not easy for everybody to fight off those
cravings on fasting days. All righty, my final take on IF, I think it is a great concept with some really promising
medical research behind it. I think that if you can skip a meal, you can skip a breakfast here and there, you’re gonna see some benefits. Does that mean you should
go on this very rigid diet where you’re doing the five
and two or 16 and eight? I don’t think we should
quite make this a religious, rigorous part of our everyday life because we don’t know the
long term consequences of it. But in a society that
is prone to overeating, a fasting day won’t hurt
and will probably help. As always, stay happy and healthy. So here we go, intermittent fasting: kind of ate the word intermittent,
it was like borderline. Our bodies have adapted to
this sort of fasting period because of throughout the millennia, blah, (growling) May people are doing this already and not not… Our bodies are totally
capable and have adapted to not being filled with
food 24 hours of the day. (laughing) Why are you laughing? Creating more mitochondria which is the energy making
machinery of the cell. Energy making? Which is the energy
center of the sill, sill? (exhales) (laughing) (peaceful music)

  1. Iยดve been waiting for so long to hear a doctorยดs sincere opinion about this. Thank you so much, Mike ๐Ÿ™‚

  2. Iโ€™m glad what you said about there not being enough long term studies on IF, I feel the same way about Keto. I did Keto for 6 months with great results but realized I donโ€™t wanna find out Iโ€™ve hurt myself in the long term. Listen to your body people!! It talks !! ๐Ÿ˜‰

  3. Doing a regimented if where one is regularly fasting at least 16 hours wouldnโ€™t it make some more prone to develope gallstones?

  4. Terrible doctor holy shit. He doesnt know what hes talking about. Not too bad if you are an average person but if you have had health problems i wouldnt recommend what he suggests

  5. when science is just figuring out the benefits of intermittent fasting but Islam taught it since 632 CE ๐Ÿ™„

  6. Will IF affect the fertility in women?? Will menstrual cycle gets affected??? I'm getting so much of advices about this. So as a doc can u help me?

  7. I still dont know what you said because you explained an opinion on it but you did not define it by a case study. By the end of the video you also seemed confused about it and then resorted to being humorous about it. So I cant trust your words because you wanted to entertain me rather then inform me with a viewpoint I can relate too. Im a fat person looking answers and I want the best possible plan to follow. I think you could have collaborated with a nutritionist on this topic.

  8. 1% Percent of the comments are discussing the main topic, and 99% are talking about how hot he is. I think he should make more contents on men grooming than medical contents.

  9. I've been doing this for years not knowing there is a term for that. I just find it hard – eating in the morning after waking up, feels too heavy in the stomach. When I was a child, my parents used to force me into eating breakfast before school, I hated that – felt like carrying a stone inside

  10. I never realized that skipping breakfast was a form of IF. I skipped breakfast for most of high school with the exception of a Yop every once in a while. There were some days I skipped lunch as well. Days when the only thing i would eat was a couple of mandarins. Granted, it turns out that (most) of the full days of not eating were caused by a medication I was on. It's nice to know that missing a couple days here and there is okay.

  11. Hello Dr, I just bought instant Quaker oatmeal. I want practising healthy lifestyle since I heard a lot of good things about eating oat. But I also read that the instant quaker oatmeal is not so good as the old-fashioned one. And my question here is can I give the instant quaker oatmeal to my father who have diabetes?. Because I just read that instant oat meal contain lots of sugar. Is it true Dr?

  12. I just started doing this yesterday, it's easy for me because I work 12 hour shifts so I eat at work where I have to bring my food with me and then stop eating by 11 oclock then just don't break my fast until the next day at 4am when I take my supplements. I haven't been on it long enough to see any benefits but I'm also on keto so I'm hoping to lose the last little bit of weight I couldn't get off with that (on keto I lost 70 pounds)

  13. I'd been intermittent fasting for a week and found a weight loss. I was very happy, until there were some changes in my schedule which meant I had to wake up earlier, so I broke my fast with a (small breakfast). I gained all the weight back within a few days.

  14. Been doing 20 hours fast 4 hours eating for 1 year 6 months. Blood sugar better then when I was on pills. Off pills. Lost 30 pounds. Feel sharp all day. Sleep less. Can excersise hard and have energy. No more pain in my gut too. Cravings for junk are gone. Once a month I fast for a day as well. Works for me.

  15. Hey a good population to study is religious groups who practice fasting as part of their worship? Members of the the Church of Jesus Christ of Latter Day Saints fast for up to 24 hours once a month. It might be a good place to start.

  16. Dr. Mike I just noticed youโ€™ve tried out both the intermittent fasting and the Keto diet (how to forget all the break up comments). In your opinion as a physician, which of both is your preference on terms of feeling better, functioning better and staying healthy.

    Edit. Just finished the video and itโ€™s not like โ€œI tried IF for 30 daysโ€.

  17. I have often wondered about this eating habit…honestly never knew it was "a thing"! Lol
    Also, the bad thing is, don't binge on naughties because you get so hungry. Eat healthy.

  18. I have pcos and my hormones are all over the place all of the time! I did IF for 2 months. I lost 20lbs and got my periods back for 5 months! Iโ€™m getting ready to go back to IF because the benefits for me were so great!

  19. As a Muslim who fasts for a month every year, intermittent fasting is a piece of cake, I mean u get to eat and drink, totally easy and healthy

  20. I like backpacking and have seen others ask on backpacking forums if anyone has tried fasting while backpacking. Me: Not intentionally.

  21. hey not trying to sound mean but you say. Contradicting statements like your starving yourself if you dont eat. You've said it multiple times in your videos. Because indermediant fasting is greatest tool for losing wheight. You should should delete the videos that contain misleading information because you as a doctor should not mislead people accidentally when it comes to wheight loss.

  22. Again, Nothing new here.
    Don't need any study to confirm its benefits.
    We have the perfect model to guide us.
    Fasting was a regular part of the last prophet's life : Mohamed sws would fast every Monday and Thursday.
    He would also fast the 13th, 14th and 15th of each month.
    Once you add them up you get eleven days, or roughly one-third of the month in which the Messenger would fast.

    When he was not fasting, he was "intermittently fasting", eating only once a day.

  23. My great-great grandmother practiced a form of intermittent fasting….she only ate dinner on Wednesdays and Fridays and did not eat anything after dinner every day. She lived to 101 with a decent quality of life until the end. Not proof of anything except that it probably doesn't do anything negative in the long term

  24. I've been intermittent fasting for over a year now, I would skip breakfast and lunch legit just because I couldn't be stuffed waking up early to make breakfast and was too lazy to make lunch for when I'm at school and basically ate as much as I felt like when I get home and from my experience I only felt hungry during those times for the first week, doing accidental intermittent fasting afterwards my body completely adapted.

  25. I am doing this for 20 years…one meal a day. So most of my life.
    Just one tip, if you are eating one meal, eat everything:fresh fruit, veggies, meat, dairy.

    I do it because when I was kid, around 10, I could not stop eating until I am full, and when I am full I can not workout, so I gain weight,
    I do gain and lose weight very fast so my muscle mass.
    If I eat and I do not have that feeling of full, that satisfaction, I have anger, hunger, not really ok to be social or can control myself when eating, I just feel calm when I am full…and a little meditation and relaxation after is priceless for the rest of the day.
    So when I was 13 I started to eat once a day, it was easy because of school, eat before school or after school depends of you go in the morning or afternoon, but home cooked meals. Still doing it, but do not eat junk food, learn to cook, do not avoid fruits and veggies or meat.

  26. Well… I've been skipping my breakfast most of my life. Ever since teen years… Only ever really eat breakfast(right after I wake up) when I do sleepovers or it's served at a hotel or the like, which is quite rare for me(like 3-5 times a year tops) I do eat early if I'm hungry otherwise I might not eat until past noon, maybe not even until Dinner.
    This has caused my mom to think I'm way overeating because she only ever really saw me eat at one meal of the day or when I was at gettogethers at familie(well, BMI sais I'm Obese, so she's right in some point, but it's taken me 20 years of controlling my own food to get there and "only" needing to loose about 30KG from my highest weight)
    I'm on my way to a healthier weight, nice, slow but steady with the help from a Personal trainer, who's also educated dietist(word?) so I can ask for advise for components to change in my diet, as the callories I intake in my daily life is within the good range that I need.

  27. Is it good for a 15 year old
    Because there is a rumour that there is a possibility of growth problem as it is the growing years and it will cause gastric or some kind of stomach problem !
    I really need a reply pleasee!!!!!

  28. I tried doing fasting where I only ate 2 meals a day instead of 3, but then I felt too stuffed after each meal since I was trying to eat all of my calories in only 2 meals. That can't be great for the body either.

  29. Hey guys! I did this for almost 6 months now (been back home for the holiday so I haven't been as strict so I won't count July into it) and I lost 20 pounds! I didn't restrict what I could eat and didn't exercise at all! In the beginning, it's hard because you're going to get insane cravings but after the 1st week, all will be good! I love it because it helped me to stop being a slave to food. I finally felt that I was in control of my appetite instead of it controlling me. Even though it was nice losing the weight, I found there are a lot more mental and spiritual benefits in my opinion. I have made this my lifestyle and I just feel much better now

  30. Hi Doc! Can I use this diet and also take vitamins? I also donโ€™t want to lose weight, I just need to use my time studying instead of eating. Iโ€™m a law student and I think IF will help a lot.

    Thank you in advance๐Ÿ™‚

  31. What the hell? I used to skip some breakfasts and I was told that that was bad. Don't skip your breakfasts, it's called the most important meal of the day for a reason, have a big and healthy breakfast and then a light lunch and an even lighter dinner. You shouldn't skip meals or else your body will store extra fat because blah blah blah. Now it's healthy to take out either breakfast or dinner. God dammit, I sure wish my body could stop changing it's mind on what's good for it.

  32. Ive been doing this for a month and I skip breakfast and eat lunch after 1 and I would recommend
    Edit: I have lost 6.5 lbs already

  33. Intermittent fasting freed me from feeling like I HAVE to eat breakfast, bEcAySe iTs ThE mOsT iMpoRtAnejerhfnedjhsdmns. It opened the door to more intuitive eating and I've been my ideal weight effortlessly for the last year. ( for reference I was consistently about 15lbs overweight at 5' tall. )

  34. This man helps me to balance my loge as someone who either is too serious or too laid off im definitely trying to change thats

  35. Please someone should answer me
    Must I exercise during intermittent fasting ?and if I don't exercise will I still lose weight? God bless whoever that answers me๐Ÿ™๐Ÿ™๐Ÿ™๐Ÿ™

  36. I can't even listen anymore to this bird brain little doc!
    The stupid statements he spews are not only misleading but could be detrimental to ppl health.
    He has NO TRAINING in human metabolism or nutrition.
    Beware whoever thinks he knows it all…BECAUSE HE DOES NOT.
    The analysis of IF is absolutely laughable..he does not know history of it or any current research.
    That shirt is too tight doc…and those phoney eyeglasses do not give you any more credence than false moustache
