How To Increase Metabolism: Intermittent Fasting vs Calorie Restriction

How to increase metabolism, Boost metabolism. What is metabolism? What is
BMR or basal metabolic rate what are the factors factors that influence your BMR? is it better to do calorie restriction or to do intermittent fasting if you want to improve your BMR your metabolism is directly linked to your ability to lose weight and even more importantly it
is linked to your ability to keep the weight off once you’ve reached your goal weight today
went to talk about all these factors and waiting to give you the big picture we make it crystal
clear coming right up metabolism comes from the Greek word Metabo which means to change so metabolism or basal metabolic rate is the rate that you’re converting fuel sources like
food into energy so the higher your metabolism the higher your basal metabolic rate the more
energy you produced per day BMR or basic metabolic rate is how much energy are you expanding
how many calories are you burning when you’re not doing anything when you just sitting around
and your body is just doing its thing the BMR is about 70% of all the energy that you
produce and out of that 70 percent we have the liver is using about 27% your brain is
using 19% your skeletal muscle is using 18% and that’s not for moving that’s just the
baseline activity your kidneys are using a full 10% heart is using 7% and all the other
organs and body parts together are using 19% what is this energy what is the body doing
well for the most part it’s simply pumping fluids around and where the fluids you have
nutrients and minerals and communication messengers that follow that fluid around so that’s most
of what your body is doing that’s what most of the work goes so if you have a good metabolic
rate not only are you so to speak burning calories but you are also helping your these
organs are doing the job and they’re being fueled properly so what is your liver do it
converts harmful substances into less harmful substances that you can process and get rid
of so there’s your detour your brain obviously handles all the communication all your mental
processes all the management of the body your kidneys are pumping fluid there regulating
fluid balance and mineral balance and they’re cleaning out junk that you want to get rid
of your heart pumps the blood so most of what your body is doing is pumping fluid and cleaning
things up and changing things from raw materials into things that you need to build your body
that’s where the energy goes So if your basal metabolic rate goes down it is basically two
organs that are involved if your thyroid slows down if your thyroid is incapable of making
enough thyroid hormone then that’s like a thermostat that just turned down your entire
metabolism but it can also be the hypothalamus telling the thyroid to slow down because the
hypothalamus is your overall regulator it is what regulates your hunger and your thirst
and your body temperature and your ph and all those different things and it looks at your
whole body and it has an idea of where you’re supposed to be so when it comes to metabolism
and weight your body has a set point then we’ll talk more about that the hypothalamus
also perceives if there is a lack it’s not necessarily a real lack but if the hypothalamus
has the idea that there is a lot then it’s also going to slow down your basal metabolic
rate so let’s put this into context give you some examples so the most popular idea the
prevailing idea the official version the guidelines from the government and every medical institution
out there is that if you want to lose weight then you have to eat less and move more the
calorie restriction calories in calories out if you’re gaining way to just eating too many
you need to eat less move more yada yada say that you have a basal metabolic rate of 2,000
calories per day and then you decide I’m going to eat less than that so you eat 1500 and
you figure I’m going to still keep burning 2000 so I have a calorie deficit of 500 and
width at 500 calories per day * 7 days is 3,500 calories one pound of fat is 3,500 calories
so the math says we’re going to lose 1 pound a week and if we keep it up for a year we’re
going to lose 50 pounds so if we are overweight rate 200 pounds or ideal weight is 150 then
this is all we have to do in a year we’re going to be at our ideal weight so the math
is playing it is logical it is can’t argue with a math the only problem is this doesn’t
work at all and you already knew that because you have tried it but every study they’ve
ever done every long-term study with thousands or tens of thousands of people show that this
expected rate doesn’t happen at all ever not even close to it so what happens is that they
predict this gradual linear weight loss that’s the black line but what actually happens is
this red line that in the beginning as you restrict something you lose weight a little
bit faster and it doesn’t matter what you restrict if you restrict carbs or fat or calories
your body will start burning through your glycogen stores and you lose fluid first
two to three to four pounds of every diet happens in the first few days and it is water
so you’re going to get a rapid loss but then when the fluid levels balance out now you’re
talkin actual fat loss so this starts to plateau very very quickly so these people might have
lost instead of their anticipated 50 than might lose 10 or 15 may be 20 or maybe five
but then it plateaus and now pretty soon they stay on the diet and they start gaining the
weight back if you try this you know that this happens and it’s so frustrating it’s
maddening everyone looking at it says oh you cheated you didn’t exercise enough you’re
just saying that to eating 1500 but we know that you just don’t have the willpower or
the character and pretty soon you’ll start believing them but here’s what happens that
you have a set point if you have weighed 200 pounds for a while then that is where your
hypothalamus thinks you should be so as you start losing weight your hypothalamus feels
threatened it wants to survive its banks 200 is your right weight now you start weighing
less so it’s going to turn down the thermostat is going to lower your basal metabolic rate
down to maybe 1500 so now you’re eating 1500 your burning 1500 there is your Plateau you
no longer losing weight but it might go even further than that because you’re still not
at your set point so the hypothalamus says I got to turn this down even further so he
turns it down maybe two 1300 or 1200 and now you start gaining weight back and that’s unfortunately
not all it’s happening because when your basal metabolic rate goes down now there’s less
energy available for these vital organs to do their vital processes so your liver is
supposed to detoxify you but now it doesn’t have the same resources before those 27% was
540 calories that was it fuels budget now it doesn’t have that much so it has to get
by on less it starts to cutting corners the same of course happens for for all of these
so now you’re getting more toxic you’re getting less repair your getting sicker because your
BMR goes down if feeling sluggish you don’t have the energy or tissue start to lose muscle
tone etc etc so let’s talk about what happened why does why is the set point so strong and
why does the body perceive that there’s a lack why the brain why doesn’t the hypothalamus
understand that you want to lose the weight and the answer is insulin. So insulin is a storage
hormone it basically helps any time that you eat food especially carbohydrate it helps
the blood sugar get out of the bloodstream and into the cell so it’s a storage hormone
it opens access for fuel into the cell where the cell will burn what you need in this moment
and it will store the excess so if you eat like most people do with which were recommended
is to eat frequent small meals high in carbohydrates than what’s happening is every time you eat
you are triggering insulin so the red area here is when you are in storage mode and if
you only give yourself a couple of hours between each meal then you’re going to be in storage
mode all the time so you’re eating 200 calories your body says better store half of that to
eating 200 calories but a store half of that and the only time that you have a chance to
lower the insulin to reverse that insulin resistance is during the night when you don’t
eat so everything is red here is in storage mode it is increasing insulin resistance and
only at night are you in the green zone where insulin is allowed to lower because when you
have insulin at a high level when you have become insulin-resistant which is virtually
everyone that overweight which means we’re talkin 85 to 90% of the population have some
degree of insulin resistance to insulin is blocking the brain from seeing all your fuel
reserves so if you’re a hundred pounds overweight you have three hundred fifty thousand calories
stored in your body but the insulin says let’s pack that way for a rainy day. Let’s put it into storage so that we don’t die during a future starvation. And that is what determines a set point. That the insulin puts the body into a starvation mode into a perceived starvation mode even though there is an abundance of fuel available. The insulin distorts the body’s ability to use the fuel properly. A lot of people
are afraid of something called starvation mode they are afraid of fasting because they
think if I stop eating I’m starving my body will sense I’m in a starvation mode and it
will lower my basal metabolic rate the starvation mode is a perception that happens when there
is fewer calories on a regular basis. It is like a form of trickle feeding your
getting food frequently but never quite enough and in the presence of insulin it gives you
the perception of starvation so the body lowers the basal metabolic rate and it tries to get
back to that set point it can’t change the set point when there is insulin present the
insulin changes the hypothalamus ability to change the setpoint what are the most popular
TV shows of all time I was called The Biggest Loser and they had all these really obese
people who were put into a camp and they were made to eat very specific calorie-restricted
diet and they were made to exercise pretty much around the clock everyone loved watching
it because people came in weighing 400 lb and they left weighing 200 pounds it look
like an enormous success on the surface but let’s look at what happened so let’s say that
these people had a 2000 calorie basal metabolic rate it’s going to be different depending
on the size of the person but just for example and then they put them on a 1500 calorie diet
they burned 2000 sort of on the baseline but then they exercised 3 4 5 hours a day so they
burn an additional 4,000 calories from exercise so they had a total deficit of 4500 so these
people were going to lose 1 to 2 pounds a day so every week they had a weigh in and
they lost 7 lb and 15 lbs and 20 lbs and and it looked like wow this stuff is really really
working and then what happened is that gradually their bodies they said they didn’t lower the
insulin all the way they lowered it sound because they were just exercising so much
they were in a deficit they lowered its some but they didn’t lower it enough so the body
started lowering the basal metabolic rate so they were eating 1500 their basal metabolic
rate was maybe a thousand so again I’m just putting a number on these are not exact numbers
and then they were still exercising about 4,000 calories a day so they maintained a
deficit of 3500 and they were still losing a pound a day so throughout the program it
looked like they were losing weight steadily which they were in a way even though it’s
slow down a little bit but what happened is they were stressing the bodies they were doing
something very unnatural unsustainable to the body and the body really really wanted
to get back up to that to that original weight and with record in hand when they any time
to do a follow up with those people who participated in The Biggest Loser almost every single one
has gained all the weight back and in some cases even more I think it’s like a single
person has managed to keep the weight off so why did The Biggest Loser look like a success
and ended up being an epic failure list four reasons the first is that they lower the basal
metabolic rate because they didn’t restore balance to the body they didn’t change the
body to change the set point they didn’t reduce the insulin resistance the second is that
the set point didn’t change the third is that deprivation is not sustainable because when
you’re in a deficit but you still have insulin there insulin storing food and trying to get
you back to the set point you get ravenously hungry and that’s okay you can do that in
front of the camera for a while but you can’t sustain it nobody can be hungry for the rest
of their life and that anyone it was tried a deprivation or calorie restriction diet
knows this that you get hungry you get irritable you get cranky you don’t feel good and nobody
can keep that up for the rest of their life The 4th reasons is that that level of exercise
is not sustainable either but even if it was that is not healthy because that body didn’t
want to burn all those calories it kept burning thousands of calories because they were in
a fight flight state they decided they made the point they pushed the people to exercise
all the time and you get all sorts of stress hormones adrenaline to make you feel good
while you’re doing yet but it is not a balanced state it’s a fight flight state you’re in
constant physical stress. It is like a survival state. That is okay for short burst and even healthy in short burst but it is not sustainable. It’s like a rubber band. You are pulling it and as soon as you let go the body wants to return to balance and homeostasis. Any time you are in flight / flight for that long you are making adrenaline you making cortisol
your burning out your adrenal glands but more than that your body cannot heal while it’s
in a fight flight state if you try to sustain that fight flight state you’re going to push
the body into failure in to break down and you’re setting yourself up for some long-term
serious disease so there’s many many reasons why it look good on the surface but it’s going
to fail miserably and it’s not healthy either in the long run but if you’re like most people
you already knew this because you have tried it and you know that there’s about a 99% failure
rate to calorie restriction nobody wants to feel deprived nobody wants to push themselves
in the long run and with insulin resistance it is like that rubber band you can’t keep
pulling it forever at some point you’re going to let go it just bounces back let’s compare
that to fasting what happens in fasting well in an sustained in a prolonged fast we
have zero calories we are not eating anything with drinking water coffee tea and in the
beginning were burning 2000 calories and with a fear of starvation mode like the people
are afraid of fasting they say oh you can’t fast you will you will wreck your metabolic
rate as we see that happens in the calorie restriction but with fasting that actually
does not happen because we expect a 2000 calorie deficit which would be about a 5-pound weight
loss per week we get just like before we get a quick drop in the beginning we lose 3/4
lb in the first couple of days and after that we maintain about 0.7 lb we’re about 5 lb
per week and with fasting four people have done extended fast this tend to be a fairly
straight line. It might slow down and curve a little bit
but it is pretty continuous it is pretty sustainable if you do if you can’t do the fasting for
all that long maybe you’d like to do a week or two and then you want to transition into
intermittent fasting with keto then you could do something for example that you eat every
other day or you do some pattern of 36/6 or 4:36 to 12 or 4:40 to 6 meaning that you eat
every other day for 6 hours to eat your 2,000 calories but it’s only every other day so
your average is a thousand calories and your body keeps burning 2000 you would expect a
two and a half pound weight loss per week and for the most part that is what happens
so how can this be because it’s all about insulin insulin controls the hypothalamus
it indirectly controls your basal metabolic rate and your set point the only way to change
the set point over time is to reduce the insulin so assuming that we start this fast in a fed
state with some insulin present but then we don’t eat then after a short period of time the insulin will drop into a place
where we’re burning fat and we are reversing insulin resistance we’re reducing the amount
of released insulin and therefore the cells don’t have any insulin to be resistant to
so they start loosening up and you become more insulin sensitive and for as long as
you keep up the fast your insulin is going to drop so you have this huge green zone that
represents fat burning and lowering of insulin and with that you are not reducing your basal
metabolic rate the evidence shows that and logically it also makes sense if we understand
how insulin works if you do an intermittent fasting pattern then you’re going to have
short periods of time where you eat where you going to release some insulin but in between
you’re going to have long periods of insulin sensitivity where you’re not feeding where
your insulin is allowed to drop where the cells become more sensitive to insulin if
you’ve done a lot of dieting if you’ve done a lot of yo-yo dieting then this is probably
what you have done over and over and over and as a result you probably lowered your
basal metabolic rate one time several times many many times and each time it becomes increasingly
difficult to lose weight so the only way that you have to increase metabolism and lose that
weight from good is to change the set point you have to lower the insulin to the point
where the hypothalamus starts believing in a new set point where it stops trying to get
back because if it’s trying to get back to a higher weight it makes you hungry that’s
what insulin does and as a result of this as part of this you have to change the perception
of starvation insulin being a storage hormone means it’s going to always put some away so
in this picture because there is insulin present from every time can you eat a little bit that
insulin is always going to have that tendency to store and if things are being stored that
means they’re not available as food so the hypothalamus gets the impression that there’s
a starvation going on so the key is to reduce insulin resistance whether you do it through
fasting or intermittent fasting or Keto or some combination of these the ultimate thing
that you have to get to is to reduce the insulin resistance because once you become more insulin
sensitive once you reduce the tendency to store you make fuel available to the body
now you can start burning the fuel but you also allow the hypothalamus to change your
set point and to let go of that perception of starvation because when the insulin less
now you have access now you have an abundance of fuel available even if you are not eating
anything unfortunately despite thousands of studies showing the epic failure of this model
and thousands of studies and thousands of individuals showing great and Lasting success
with this model the calorie restriction model is still the prevailing official recommendation
when you go to most medical doctors and most dietitians and when you go to the Mayo Clinic
and you read the American Diabetes Association guidelines and the USDA guidelines then they’re
going to tell you that you need to eat low-fat high-carb control your meals eat frequent
meals and all of the regular stuff that has been shown over and over to be epic failures

    Great video, never had it explained to me. The famous Oslo study done in the 60's, used sudafed, caffeine, and asprin 1/2 tab, to keep the BMR from changing when there was a caloric restriction. It worked by thinning the blood to make the hearts job much easier, and stimulating the BMR.

    I have been on Metformin for some years. Since may I am on keto with one or max. two meals a day in a 6 hour window. I feel good, but don't lose any weight. I stopped Metformin 2 weeks ago and my blood sugars are OK (95 to 110 – checked several times a day). How do the years of Metformin affect my efforts?

    Dr. Ekberg- my 13 yo daughter is currently on Keto she has been on Keto since 6/17 , she is in keratosis, blood levels range from
    1.0 – 2,4 . She has lost 10 lbs. but recently has slowed down. Would putting her on IF/Keto help her Drop faster so she stays motivated? Your input is appreciated. Her SW 190 CW 179 GW 120 she is 5’1” tall.

    To be honest, you have the best health channel on YouTube and deserve much more views,your videos are awesome,highly informative and your style makes it easily understandable.please keep up your great work. Really appreciate you guiding us in real health matters . After watching your videos I’m feeling v knowledgeable in understanding how body works and how we can succeed for healthy goals. Thank you

  7. N T

    You keep saying “basic metabolic rate. It hurts your credibility when you make such a mistake. Please redo this video using the correct term “basal metabolic rate”.

  8. Misslou2425

    I want to combat the insulin resistant that occurs for me postpartum . I have always been naturally thin but have a period of insulin resistance crop up after a baby. ( am pregnant now). How does one incorporate IF during the post partum period if breastfeeding, please? Thank you.

    Extremely and Valuable Information for Me and i Appreciate you and looking for more video from you regarding insulin and body

  11. jj Fox

    Dr.Ekberg, I love your channel very much, it really helped me… hear is why, I was diagnose with Type 2 Diabetes a year and a half ago, in 11/2018 my A1C was 10.5, so, as expected I was put on metformin, my body did not like like this medication it gave me a lump in my stomach, I guess these pill were too big for my stomach to handle,this really hurts… I told my doctor and she said she never heard of this before, anyways,she changed it to Victoza,my body did not like this either,it made my heart race too fast, when I went to get my physical, she saw it,I felt it, that my heart was beating too fast, but she did not say anything to me,i said to her I think the medication is making my heart beat too fast,she said I don't think so…I left her office, went home and watch some of your videos and another person videos and between you both I lost 50lb in six months…went back to her office on 7/8/2019…she was amazed at how much much weight I lost,I did my blood work and guess what? My A1C is 5.5,have not taken any medication since, even though,she did call to tell me to stop…this is the best I have felt in along time…By the way,OMAD, keto and intermittent fasting did it for me. Thank you on the great work you are doing,to help people like me and others who have/had Type 2 Diabetes.

    how long it will take to inc. my BMR to 2000 from current 1200? for example i ll do 2 weeks fast and then keto for 6 month is it will be enough? 32 years. my bmr was that high before i started messing with calories and diets.

  13. TheRealThing

    What about how to DECREASE metabolism?? I struggle to maintain weight like many people do.. I eat more than I can comfortably digest as it is.

  14. Dadvice TV - Kidney Health Coach

    Great video and very thorough explanation. I have been using both Keto and Intermittent fasting to help me lose weight and it has been extremely effective. Your information about the organs using part of your BMR was new to me and very helpful!

    During intermittent fasting I seem to have thinned my hair out in the front and it’s really scaled a lot kind of bumpy at times what can I do to regrow the hair I normally have a thick head of hair thx in advance for your response

  16. dearinlove

    Thank you Dr, Sten, I am on an OMAD lifestyle right now. I dont have calories restriction, I eat whatever I want, But mostly healthy. It works for my life right now, but getting here was a slow transition. Can you please make more videos on OMAD videos, is eat healthy for the long run? I am a 32 year old woman who has plans to have kids, and I just really love this lifestyle how easy it is for me.

    Thank you Sten for these awesome videos! Being a Swede myself it is refreshing to listen to proper English (not the horrible Swenglish) and you have an extremely good ability to get the message thru ("pedagogisk färdighet"). Tusen tack! 🙂

  19. Cindy Salter

    I have been on a journey of healing my body from years of abuse since around April 1st. I absolutely love Dr. Ekberg's videos as they are informative and easy to understand. After converting to low card/keto eating, I began to read and study a lot about fasting. Around the end of June, I started experimenting with fasting and lost 8 pounds in two weeks. The lost weight seems to be stable and not related to water weight as in the past. Dr. Ekberg's videos help answer all my questions and provide hope that I can heal my body.

  20. Sergio Bravo

    Hello. I am 45 years old male. Tryed IF and lost some fat but also muscle mass and strength. My squat and deadlift dropped 20%. I think IF might be good only for morbidly obese but not for people who want to stay in shape.

  21. Angelia Bates

    Explained so well. I am doing IF/Keto. With. a 16/8 window. I was afraid I wasn’t eating enough calories. I simply wasn’t hungry.

  22. Samira Etoile

    Excellent topic clearly explained, thank you so much for teaching us what real health is and should be! What if someone eats sourdough made home. What is the impact on keto diet? Thank you for your answer.

  23. Mette Harter

    Thank you Dr Ekberg, I’m sure this is what will help me, I have completed 3 days of fasting, and going strong (somewhat).

  24. Vivianne Rozsa

    How about a video on sensitivity to too much fat consumption. People around me who are trying to do Keto can’t because their livers ache after a few days.

  25. bjorn2fly

    You are correct about the insulin, making you fat, but the body have no set point for weight. It just misunderstands when you eat all the time, and there is still too little energy, and assumes there is starvation. The only way to solve it is fasting or roux-en-y bypass.

  26. Andras Libal

    Yeah one way of getting on my good side is telling me I don't have the willpower or character.
    Especially when I am already hungry and aggressive because I am hungry 🙂

    What is the best diet and herbs / supplements for primary biliary cirrhosis? Conventional doctors just prescribe medication to help with symptoms such as itchy skin but do not help with treating the condition.

  28. Urszula Fraczek

    You are great teacher ( very talented).I share with your videos with my friends.
    I live your Chanel. You explain in very clear way so is easy to understand the complex metabolic process
    Thank you for everything what you do to help people improve their health. The knowledge that you present through your videos influences my concern for my health ,motivates me .
    Results of my medical tests are getting better .
    Thanks a lot.

    I have been eating Keto for about 3 months between noon and 6 pm, but haven't lost any weight or gotten into ketosis. My question is: Is my body gaining any other benefits from eating so healthy and intermittent

    I would love to hear you comment on the debate between Gary Taubes and Stephan Guyenet which took place on the Joe Rogan podcast. It was so frustrating to watch. I'm sure that you could greatly clarify things.

  31. Prue Christie

    What a wonderful presentation Dr .. so clear and really well explained … Fantastic !!loved it ..all your video !thank you for giving us all your precious time it's so appreciated!! here ! 😊.👋👌👍

  32. rlearner23

    Nice video and explaination. I have no problem doing intermittent fasting but being not able to eat non vegetarian food I can not do diet low in carbohydrates. I am pre diabetic and need to loose nearly 20 kg. Would IF work without cutting carbs.

  33. Ciudadano Español

    Dr. Ekberg. What can I say ? Thank you, thank you and thank you.
    It's unbelievable how doctors are submitted into the wrong knowledge and reluctant to change.

  34. B A

    Again: Thank you for all the excellent information, sir 🙏🌺 I have one question for you, dr Ekberg; Can you do the intermittent fasting every day in the week for the rest of your life?

  35. Patrick Grogg

    I am a goal oriented person and one who likes lists of things to check off. I know everyone is different and respond differently but can you give a ballpark to when you can expect to no longer have IR and that you have reset your weight set point? You said in your video that a person who has been at say 200lbs for a period of time. Other than that you did not address it. I have recently been diagnosed with prediabeties and I am on metformin. However, I find the IF and extended fasting intriguing. So, I started a 17/7 IF schedule and did great then just decided to move it into an extended fast. I am 72 hours in and still feel really great. I am just wondering how long until one can expect to see their IR go down to acceptable levels? I test my blood every day and it was 78 this morning. Down from 103 when I started this extended fast. Makes sense since I am not eating it would drop.

    Again, I know that everyone is different. Just would like to know some ballpark time frames. Thanks. I have found your videos very helpful in understanding my condition and a way to reverse it.

  36. hope king

    He is so right! I was up to the point of walking 2 he a day! I'd lose 30 then I have to exercise and I would go threw horrible times where I'd not lose weight. And people would say you must have a problem you are exercising two hr a gonna do intermitting fasting. Cause I should not have to bust my ass and make my thys hurt!

  37. hope king

    I refused to be put on meds for this. I never did but my wieght wants to be 340 at 5'2"! Not good! I'm almost 60 and I'm dam sick of it! So yes I'm going to try fasting

  38. Diego Rens

    This is one of the best videos on these topics that I've seen due to how concise it is. For those trying to lose the blubbers it pretty much says it all !
    Thank you

  39. K Jenks

    I’m unclear if the mechanism to change your setpoint is lasting. In other words, if I periodically go back to three meals a day, and I do intermittent fasting only a month or two a year, will my setpoint really be changed or will my body still creep up to the original weight during the 10 months I eat 3 meals? Assume I’m still on keto and not a carb eater. Does it just change during the time you’re IFing ? Is there a test I can run as an indicator ?

  40. Sunny Deise

    A holistic doctor who was also an Olympic decathlete who can explain things that have been debated about forever in a simple way that everyone can understand. Someone give this man a hug today, much gratitude, good sir, exactly what our species needs 😍

    Thank you so much for sharing this Dr. Ekberg. I've never understood why our BMR lowers during calorie restriction but not IF and many lectures I've watched gloss over this important mechanism that is insulin makes the hypothalamus not able to see the available calories and hence it lowers the BMR because the body literally has no access to the fat cells since they are "locked". Now it makes total sense that by lowering insulin, you don't go hungry because the body doesn't need to signal you to add more fuel since you actually have a large depot of energy in the form of lipids and the body knows that it is meant to be used when there is no external intake of fuel. This video is going on my AAA lecture playlist. Thank you so much, bless you, Dr. Ekberg.

    Dr. Ekberg, i love how you explain and now understand more than other videos i've watched. But, i'm still confused, if someone were to do a 16/8 IF with lets say 2 large meals and burns 2000 calories/day, should the person have 2 large meals of 1000 calories each to equal 2000 burned (so as not to reduce bmr) for fat loss, or do they still need a "calorie restriction" of less than 2000 calories/day (ie 2 meals of 800 calories = 1600 total/day for example) for fat loss? So in a way, IF is sort of like "calorie restriction."

    Edit: i understand the example of eating 2000 one day and fasting every other to get a deficit of 1000 a day for 5 lb/week loss but i don't understand how to incorporate that into an IF of 16/8 every day. I'm not sure I can do a 36-48 hours fast at the moment, have to work up to it without feeling faint/sick.

    is there a video where u explain the relation between the hypothalamus and insulin better, what i dont undestand is how the insulin resistence decreases the bmr in other words lowers the metabolism? i saw in one video that when we have insulin it basicly says to the hypothalamus that we dont need food.

    First off this guy makes Dr Oz look like a puppet but when he said "a lot of people here are afraid of starvation " I cringed , we are thee most gluttonous over eating ungrateful band of entitled people on the planet and single avg person throws out more than a pound food in a day and part of the world they won't even eat half that ! THANK YOU FOR YOUR INFORMATION I BELIEVE KNOWLEDGE IS A POWERFUL TOOL AND SELF KNOWLEDGE AND ACTION ON THAT KNOWLEDGE EQUALS SUCCESS !
    Be blessed to all

    Thank you so much for the video. I’ve tried IF+Keto for few months, but it seems the setpoint didn’t change (maybe). Can you explain more about how to change the setpoint more specifically? Thank you again.

    I actually lost 47 lbs in a period of 3 months, through calorie reduction, and exercise. I kept it off until I injured my shoulder and wasn't able to work out, and began overeating. . . It does work for some, but requires constant attention. At least, it worked for me. I worked out an hour a day, 3-4 times a week. (I was 51 at the time) I currently am about 20 lbs under where I was.
