Keto vs Fasting – Which Is Better

Keto vs Fasting – Which Is Better


hello health champions today I’m going
to talk about keto versus fasting the ketogenic diet versus fasting or
intermittent fasting so in this video you’ll learn how they are similar and
how they are different so that you’ll know how to pick one over the other or a
combination of both so you can reach your health goals the fastest and in
perfect health coming right up the first thing they
have in common is that they are very strict on carbohydrates they restrict a
lower carbohydrate so in the ketogenic diet you will eat typically less than 30
grams of net carbs per day and when you cut the carbohydrates that low you will
also dramatically lower insulin so insulin is a fat storing hormone it
converts excess fuel into fat and it prevents the burning of stored fat for
energy number three when insulin goes down dramatically therefore then the
body is allowed to start burning fat when we reduce carbs dramatically the
body has to find an alternate source of fuel namely fat but it can’t do that
with a lot of insulin around so all of these three things work together
number four is ketones ketones is an alternate brain fuel and the ketones
they result they’re a byproduct of fat burning so when the body learns to use
fat for fuel there’s a lot of ketones around and now they become the primary
fuel for the brain so in the absence of glucose when we don’t have a lot of
carbs floating around in the system then up to 75% of the fuel for the brain
becomes ketones number five ketones the ketogenic diet it reduces
inflammation most inflammation is due to insulin and all of the factors
associated with insulin and all the factors that promote metabolic syndrome
and leads to cardiovascular disease and diabetes and strokes and so forth so by
reducing insulin dramatically we also reduce inflammation number six they both
increase mitochondria and mitochondria is the little powerhouse inside the cell
it’s what makes most of the energy that you have access to on a daily basis and
because mitochondria can only use oxygen and because fat can only be burned
through oxygen then when the body gets fat adapted it’s going to up regulate
the number of mitochondria so you’re going to improve your ability to produce
energy through the mitochondria number seven glutathione is the body’s own
antioxidant there is a lot of talk about eating antioxidants we got to get the
fruits and the vegetables and the plants and they have antioxidants and that can
be beneficial not necessarily for the antioxidants but the only antioxidant
that really truly matters is glutathione and the body can make it itself it’s our
internal intracellular antioxidant and through a ketogenic diet or fasting
we’re going to increase that production number eight we have a decrease in
cancer because cancer loves sugar and carbohydrates and cancer does
comparatively better than the rest of the body cells when oxygen is low and
glucose is high so by changing all these previous seven factors then cancer is
not going to thrive as much and the body has a much better chance of not feeding
it and allowing the immune system to destroy it and clean it up
so all these eight factors are the same in Kido vs. fasting except that in
fasting they happen more whatever Kido benefits we
get we get more of them when we do the fasting and why is that because Kido is
a restriction in carbohydrates fasting is an elimination of carbohydrate so if
we think about this on a gradient as from a high carb low fat diet might have
300 or more grams of sugar and carbohydrates and Mediterranean diet
might have a hundred to 200 a Paleo diet might have seventy to a hundred low carb
high fat starts at about 50 to 70 and the ketogenic diet is anywhere from less
30 or less all the way down to 210 or even zero but fasting is zero
carbohydrates we’re not eating any carbohydrates and not only are we
restricting the carbs but we’re restricting all the nutrients so if we
compare the two then the ketogenic diet and the fasting they are the closest
together at the one end of of the spectrum so in that sense they’re very
similar to each other fasting just takes it one step further
so those are the similarities what are the differences how do they differ if
fasting can do more is there anything else that fasting exclusively does or
that keto exclusively does well there’s something called a toffee gee that means
self eating and that only happens to any significant degree when we have extended
fasts when we go for a long period of time usually 24 hours or more even maybe
48 hours or more then we’re not adding any nutrients to the body we’re not
adding any building materials or any energy substrate so the body has to get
really really good at recycling and using the stuff that we have so
therefore it up regulates the cleaning crew and it sends out all of these
immune cells and all these different macrophages and they start recycling and
then once you start recycling they also get better at repairing because all the
tissues become more precious and now we got to take care of everything because
there’s nothing new coming in it also up regulates the production of stem cells
it up regulates the function of the immune system because that’s part of the
cleanup crew and because we’re not adding any protein either protein
becomes the most precious resource we have typically enough fat that we can
generate energy but protein becomes very very precious and in order for us not to
break down muscle we have to get really good at recycling the protein and
therefore the body up regulates growth hormone so an extended fast can up
regulate growth hormone by as much as 2,000 percent that makes sure that we
use the protein that’s available to the optimum degree and we maintain those
muscles so there’s a minimum of muscle wasting during a fast so fasting has all
of those benefits then why wouldn’t we do it forever well that’s pretty obvious
because if you don’t eat eventually you’ll die you’ll run out of fuels so
that’s the limitation of fasting that you can only fast as long as you have
enough resources in the body then the body sets that limit and you don’t get
healthier you get sicker that’s the benefit of the ketogenic diet because
with the keto diet you still get to eat you still get to put enough fuel in the
body to function you’re just not putting in the carbs to trigger the insulin and
when you can eat you don’t have a problem with hunger as a matter of fact
hunger usually decreases when you don’t have the blood sugar fluctuations people
typically notice that they get less hungry on the ketogenic diet and that
has two benefits when you eat less you tend to lose weight if that’s
goal but what I find is when you’re less hungry you don’t have to eat so often it
saves a tremendous amount of time to only eat once or twice a day and you
don’t have to worry about getting up in the morning and having breakfast every
day you just grab a cup of coffee or even a bottle of water and and you’re
good because your body is fat adapted your hunger has gone down because you
get to eat the ketogenic diet is sustainable if you wanted to you could
maintain it for months or years or even longer because you can eat and you can
work out you can continue you can maintain your muscle or you can even
build muscle while staying on a ketogenic diet and if you have a highly
active job or if you have hobbies that require a lot of physical activity and
energy requirements then you can still eat and supply those energy requirements
so these become obviously the the drawbacks of the fasting that it is not
sustainable that you will experience some hunger because you’re not eating
it’s typically not as bad as people think because your body sort of you get
hungry for a few minutes you drink a cup of tea and then you’re good for half a
day so it’s not as bad as people think but you will have some hunger when
you’re fasting it is not sustainable indefinitely obviously because at some
point you run out of fuel you cannot build muscle on auto Fiji because you’re
not adding any protein with with fasting and etaf adji the protein in the body is
fixed you will lose some because the recycling isn’t a hundred percent
perfect so you can’t build muscle and eventually even though the auto Fujii
and the high growth hormone will maintain muscle as much as possible it
will burn the fat first and spare the muscle eventually if you go on a fast
long enough then there will be a certain percentage
protein that’s lost and you’re not adding any new so you will lose some
muscle also if you require high activity then fasting might be a little bit hard
to do that because the etaf adji the fasting is a little bit stressful it’s
so focused on healing and recycling it may not be able to generate a lot of
energy in the long run for a physically demanding lifestyle so that’s how they
are similar and that’s how they’re different that’s some advantages and
drawbacks so let’s just kind of pull it together and consider who might want to
use this and when so the question is if you’re trying to lose weight how much do
you have left to lose so if you have hundreds of pounds left then no problem
you can go on quite a long fast you can extend it for a good bit thirty days and
maybe more or you can do the 30 days and then go keto intermittent fasting for a
while and then do another 30 days and if you have to lock a lot stored to burn
then you can do that if you’re thin like myself then you can’t go very long I
still do a fast once in a while I’ve done two fasts recently this year in the
last year of four days and that gives me a tremendous amount of auto Fujii my
ketones went sky-high and I get some of these benefits but I can’t go much
longer because then I quickly start losing too much weight so that’s the
main factor of how long you can go is how much do you have to lose next
consideration is how insulin-resistant are you and you don’t want to measure
this by blood glucose so some people who are type-2 diabetic they push their body
into that state for four decades they might have a glucose of 300 and still
not be as insulin resistant as some people with a much lower glucose some
people who are full-blown type 2 medics they just cut out the soda and
their body starts reversing because they even though they had pushed their body
quite far they hadn’t really sort of destroyed the body they didn’t have a
predisposition for it necessarily whereas someone else who might have done
ketones might have been in ketosis for months or years and who for some reason
cannot seem to lose a lot of weight they might still have a lot of insulin
resistance and how do you figure this out you do it by measuring fasting
insulin not the fasting glucose because glucose changes all the time
fasting insulin is going to give you the best picture of how insulin resistance
you are because if you cut back your carbs and your insulin stays high then
you’re very insulin resistant and if that’s the case then even if your blood
sugar is normal you might have to go for a good bit longer you might have to go
for a week or more before your body really makes a dent in that insulin
level next consideration is how active are you if your lifestyle requires a lot
of physical activity either through your job or through hobbies then you may not
be able to do a whole lot of fasting but if on the other hand you have more of a
desk job a sedentary job you don’t have a whole lot of physical activities you
might do an occasional like very very brief hit exercise or just enjoy
leisurely walks then there’s no reason why you shouldn’t be able to fast quite
extended ly because you even though you don’t put a lot of calories in your body
your mental focus is typically better on both keto and fasting than it is on most
standard diets so a lot of people they start fasting or doing keto they’ll
actually notice better mental clarity better focus another consideration is
how quickly do you want this to happen so just like we talked about fasting
does basically everything Quito does but it does it quicker so if you’re in a
hurry if you really really want this to happen quickly or if you just want to
give yourself sort of a jump start if you’re a type 2 diabetic and you want to
get out of the starting blocks running then it might be a really good idea to
start off with an extended fast maybe 7 1014 days so how do you do the fasting
how do you get into it well most of us already are fasting 12 hours every day
if you have your last meal at 8 p.m. and you eat breakfast at 8 then there’s 12
hours during the night where you are fasting you’re not putting anything
caloric and your nutrition into your body and then all you have to do is push
your breakfast a couple of hours later and put your dinner a couple of hours
earlier and you have gone to a 16 hour fasting window and that is how I would
recommend for for most people to do this okay you start where you are and then
you just nudge the Border’s you nudge the limits a little bit and you teach
your body gradually to get used to it then you slowly become fat adapted you
teach your body that there’s a longer period without food and it figures out
what to do then and then you can push this maybe all the way to 20 or 24 hours
which is called one meal a day and a lot of people find it very convenient and
very simple to do one meal a day and once your body has gotten to that point
now you can try and skip a day so you do 36 hours and then 48 hours and so on and
once you’ve tried that and you know what your body feels like how it reacts how
you feel now you can go 3 4 5 days and you’re gonna be perfectly fine your body
is going to be stable just pay attention just notice how you feel and if you
don’t feel good then something and if you notice that you can
do several days and do fine or maybe even a week then if you’re still feeling
fantastic like a lot of people will at that point you could go up to thirty
days I wouldn’t recommend going very very long unless you have medical
supervision someone who can monitor closely who has some experience with
that but if you just increase it gradually and you pay attention to how
you feel then you should be perfectly fine I would however strongly recommend
with both the ketogenic diet and intermittent fasting that you monitor
that you measure your glucose and you measure your ketones so that you know
where they are because glucose should go down and ketones should go up and if
they don’t if glucose goes down but you’re not making any ketones there’s
something wrong alright so if you don’t get these expected changes then you want
to kind of back off and regroup and try it again maybe consult with some people
and see why aren’t these changes happening so if you fit into one of
these four if you have a lot to lose if you’re very insulin resistance if you’re
very if you’re not so active and if you want to lose it quickly then I would
suggest that you experiment with some longer fasts if you don’t have any of
those four then you probably just want to do a combination of keto and
intermittent fasting maybe throw in a two or three day fast a few times a year
to get the autophagy benefits but you probably are going to find that the keto
plus intermittent fasting is going to get you to your goals and you’re going
to find it a very comfortable very doable lifestyle if you enjoyed this
video make sure you take a look at that one thank you so much for watching I’ll
see you in the next video

  1. Watch more about what is better or worse for you: https://www.youtube.com/watch?v=_uEWltsZGTI&list=PLpTTF6wMDLR5tjNfMLc-5RpRzxK5D0yqH

  2. Thank you so much Dr. Ekberg
    I just want to enquir, what do you mean by fasting in your topic
    Is it the extended fasting for 3 or more continuous days.. Water fasting… Or intermittent fasting from 16-23 hours

  3. İ have been fasting for 30 days for so many years its called Ramadan and fasting twice a week its called sunnah

  4. Doc, I am confused. In all your videos you mention carbs. But plants HAVE carbs. So when a keto diet suggests 30grams of carbs or less, that means that I could ony eat veggies up to 30 grams or less. Am I getting this correctly? Please clarify. Thank you

  5. Hello Dr Ekberg, great video as always. Well explained!!! My question is though is, if carbohydrate consumption is not necessary by humans, why does the salivary glands in the mouth have the ability to produce the enzyme amalyse for digestion of starches?

  6. Dr Ekberg
    Great lecture thank you. I am on both keto and IF. I am in a very good health and mental health however my uric acid is very high( UK normal is up to 300 mine is 600) do you know why and any suggestion please

  7. Thank you. thank you, thank you! This is the information I have been looking for. I appreciate how clearly and thoroughly you teach. I understand so much better when you explain things.

  8. Hi Dr, I want to know where the info comes from in your video '#1 Absolute Best Way To Lose Belly Fat For Good – Doctor Explains' (any references or books, anything etc) as want to study this further please . Very good videos keep up the good work and getting the truth to the masses.

  9. “Mitochondria is the powerhouse of the cell” is the only thing I retained from grade school. Glad it’s still relevant to my life 😂

  10. Hej Dr Ekberg,
    According to my scales I still have 40% body fat (BMI of 27, coming from 34.6) and I would like to do a longer fast. I don't feel all that hungry when I do a 4-day (or so) fast, but I start to get dizzy around that marker and my blood sugar gets as low as 2.3 mmol/l (with ketones between 4 and 5 mmol/l). But to get my blood sugar up a bit I would have to break my fast, lest I keel over …? Is it preferable to eat a little bit of keto food at that moment and then go on, or to stop the fast and do several shorter ones, rather than one long one?
    Tack så mycket!

  11. I have been having less than 20 grams of carbs (not net carbs) and fasting from 2pm till 7am the next day and I haven't lost much. Why?

  12. After being obese for 25+ years I finally lost all my excess weight in 2019. I lost 34kg doing fasting and keto.
    This is not the first time I lost weight, but it's the first time that I am being able to maintain it.
    All of this thanks to your videos and your teachings.
    Thank you so much doctor! 🙏

  13. 1: On previous vids you say autophagy starts at 18hrs now you say 24hrs?
    2: And are u seriously telling obese ppl to go straight into a 30 day fast?
    3: in a time when people were often lucky to eat Christ went on a 30 days fast, He had visions thought Satan was tempting him and nearly died. Yeah that would work for the average person nowadays. Complete quackery!

  14. I have pretty bad hypoglycemia and a high fasting insulin level although I’m somewhat thin, would you suggest doing OMAD very low carb for a couple weeks, to lower the insulin resistance and heal quicker? I’ve tried 16/8 and I always fall off the rails with little results, perhaps just going all in could give me more motivation to heal this, I can gain weight back once I’m healed.

  15. How can someone be in ketosis for long months and still has very high insulin????
    I know liver can and will always generate glucose but in the presence of insulin there will be very low or no ketones at all.
    Correct me if I'm wrong..

  16. Hello Sten. Is it true that insulin is not only fat storing hormone but also muscle building? Can we build muscles without insulin spikes?

  17. My wife says she does keto, but then her blood sugar goes too low and she feels like she's going to die. She then eats some ' emergency ' carbs, but then she has to inject some insulin. I know she has no will power but strangely enough I sometimes feel dizzy and like I'm going to die and eating helps me. I don't eat carbs and I'm pretty sure I'm not going to die from that, but what causes this ? It lasts from 1 to a few hours and I literally feel so weak I can't hold my head up.

  18. I tried longer fast to loose weight quickly . On the 5 day I had back pain near kidney area and had to quit …I’m perfectly healthy.. when I do long fasts I face this on 5 day always .. any ideas to overcome this ..? Appreciate your help

  19. From what I understand, having high glucose is not good. I know normal fasting range should be 70 – 90 and I would think that would be more important rather than high insulin. I know high glucose can cause bigger problems like nerve damage. Decreasing glucose is easier and more beneficial. Worry about the insulin later. Anyways today's high carb diet, you are automatically insulin resistant and shouldn't be considered normal eating.

  20. I’m glad you brought up your own fasting practice because I too am now at my ideal weight after losing 25lbs since going Keto in September. IF became easy but I can no longer afford to lose more weight so I’ll will reduce my fasting to once a month so I can get some of the benefit of autophagy. I’m 63 and am the weight I was in my late 20’s. I changed to Keto due to family history of Alzheimer’s. Antidote; my plantar fasciitis that I’ve had for a few years is gone in both feet.

  21. My body tells me how often to eat. I find i do one meal one day and 2meals the next day, automatically . I spread the calories over a week, rather than daily.

  22. I can “dig” everything you’re saying about low carbs (ketosis) and IF,
    I went on OMAD and now it seems normal, so everything’s great.
    But now you say “30 days “!
    Just casually. I’m trying to think “why?”

  23. With greater mental clarity through Keto and IF comes more enthusiasm for life and its pleasures. I'm 58 and fast 22- – 23 hours per day and once a week I fast 46 – 48 hours. I train HIIT and weight lift on an empty stomach. Bone broth, with the rendered fat, is absolutely paramount in my daily food intake, I treat it as a sacrament, it is singularly the most important part of my eating regimen.

  24. What would you consider an ideal fasting insulin result? I’ve read so many different things and the “normal” range on my blood test seemed way to big of a range based on what I’ve read. Thank you for all your excellent videos!

  25. I would be so interested in a video about keto for women in their periods and how progesterone is affected by that, what to eat , etc. thank you!!! 😍😘😘

  26. So perhaps an easy transition would be to start off from a high carb diet, to a Mediterranean diet, to a paleo diet, then to low carb and keto with fasting 🙂

  27. Hi Dr Ekberg, I love and watch your videos a lot recently. However, I want to challenge something you said at 3:51 about how cancer loves sugar. I have seen cancer patients die while on ketogenic diets. I have seen cancer patients cured using Gerson Therapy which is in short a diet of 13 juices (orange, carrot and vegetables) plus coffee enemas etc. Please I hope you study into Gerson Therapy and this will help you understand better about things. Dr Gerson used this therapy since early 1950s when cancer was already present. There are also Gerson Therapy groups on Facebook. It's legitimate and has helped save many very sick and incurable cases, even though it may not cure every type of cancer. Thank you.

  28. Hi Dr. Eckberg! I was diagnosed with type 2 more than 25 years ago and struggled with the recommended treatments with no success and as a result I was labeled a Non compliant patient. That title did more to make me rebel from the treatments than anything else. All of that got me painful neuropathy, heart failure and problems with my eyes. Fast forward to last September, I finally discovered doctors Boz, Berry and Fung and finally made the decision to turn my health around. I started a relatively strict Keto diet along with IF. I stopped taking any insulin and victoza. I soon got to where i was mostly OMAD and soon started losing weight. I have gone from a BMI of 29 to now less than 24. My last A1c was 6.6 from higher than 7. I've been listening your videos lately and am getting such good information to keep me going in my journey! Thanks for all that you are doing!

  29. Thank you very much for the VDO. Again an excellent VDO! I would aso appreciate a comparison between Keto and IF with a "normal carb" whole foods diet. With "normal carb" I mean what is recommended by the regular/main health authorities, i.e. the five groups of food:
    – Vegetables and legumes/beans
    – Fruit 
    – Grain (cereal) foods, mostly wholegrain and/or high cereal fibre varieties 
    – Lean meats and poultry, fish, eggs, tofu, nuts and seeds and legumes/beans 
    – Milk, yoghurt cheese and/or alternatives, mostly reduced fat
    Thank you!

  30. Am I breaking my overnight fast by putting whole milk in my 2 mugs of morning tea please? Then I don't eat until noon.

  31. I like the way you say champions!! In reality I feel you are the real champion…by educating us and improving our life…

  32. Thanks for all the Videos Dr Ekberg! I would really love a videos on Keto / IF sports nutrition. I am a marathon runner and starting keto. What would i eat before or during the long runs, as all the power gels ec are pure sugar. You are obviosly a athlet, maybe you can do a video on that? Thank you!

  33. Great video! Dr.Ekberg => Do You agree in that =>? Some people think that ketones could work as an alternative to glucose for the whole body – misunderstanding that this only applies to brain metabolism.
    My try of biochemistry: Ketones are an indicator of fat katabolism, but the whole body never could “run” just on ketones. Fat is metabolized to Acetyl-CoA which goes into the citrate cycle, which provides us with energy. If there are more fat-acids in the LIVER than it can use or store itself only the liver produces ketones which are secreted into the blood. Ketones are not “healthy” or better or worse than any other way in biochemistry and as well metabolized to Acetyl-CoA => citrate cycle as glucose or aminoacids or fatacids. So, if we are fasting or doing Keto diet, we emphasize primarily the way of burning fat. And because we see an increase in ketone bodies, we call it “keto-/genic diet”.

  34. Dear Dr , i am in all my life bin fit and not fat but i have a few tumor , then 5 years trying to cut graind and suger , in 2019 i was really totally low carb , no any grains my food was only veg and egg and meat but no oil . i did only half kg weight lost . but i am sure i have problem with suger from kids time . i had always pimple and yet in 55 some time i have . today is two days i am in fasting only herbs no any food .i fell good . i am not hungry at all . i have some fat in abdomen yet . can you pls talk abut INOSITOL also . thanks .Parvin

  35. after 48 hours fasting i will start with boil veg and add oliven oil ( bist guality) and add ashwaganda , may be lowing crotisol , can little more help me .

  36. Dr. Ekberg, my IR is 2.4, I am trying to become Insulin sensitive (<1.5). I have started 20:4 clean keto with 5 miles walking everyday. How long before I become Insulin sensitive ? please give me a hint at least.

  37. Hello ,I started keto about a month ago doing well but I am so tired,barely ave energy,I workout at least 5 times /week in the gym about 90 minutes by the end of the week I am so tired ,my age is 74 any help what do I do wrong,I measure my keto in urine and one day it’s higher one day it’s lower but still in ketosis

  38. @Dr.Ekberg
    Thanks from Sweden for
    clarifying thrustworthy
    u-tube channel !
    Bravo++++
    I have a Q for Dr Ekberg:
    Clarify please how the popular MCT-oil use can be a good idea when this oil is loadwd with Triglycerides and the ratio between serum levels of Triglyc./existing HDL in the bloodstream will be affected in a NON-desirable direction by adding MCT-oil to your intake ! This doesnt make sense !

  39. I have done the lemon diet several times up to 14 days. Feels great, but now that I am learning about atophogy. I was wondering if the cayenne pepper with maple syrup in small doses never let me go into atophogy?? While fasting should we be concerned with drinking electrolytes?minerals and vitamins?

  40. I still eat carbs but it's from berries, sweet potatoes and other veggies. Right now I'm doing 72s back to back and stuffing my face when I eat. Once I'm lean I'll go back to omad.

  41. Dr Ekberg, Thank you for taking the time to provide a visual by writing the information on the whiteboard…. It helps to organize the information that you provide in our minds…👍💪

  42. Lost weight everywhere doing Keto and IF. I look great. Only problem is the belly fat above my navel. I have extremely stubborn belly fat in that area. Help

  43. I agree the 8 hours eating period with 2 meals within that time is best ,like from 12.00 until 20.00 h is best for most people .

  44. I have a ?. I did an extended fast a whole ago and after 10 days my heart rate increased and I had heart peats that I could feel through my chest. I did not know what that was about and ended the fast and have been afraid to try again. What could have caused that?.

  45. I have been doing Keto for about three months and lost 38 lbs.  Hunger was well controlled and have done several 72 hours fasts for the Autophagy benefits.I have recently switched to Low Carb and Hi Protein as I found I was really losing muscle mass and had to get it back up. The down side is that I am getting aggressively hungry even though I am Low Carb.  The weight loss has stopped but I am feeling better.  I am sometimes burning in excess of 4400 cal/day on the days that I am at the gym and can only see this as my body wanting more energy intake.

  46. Would carb intake (low GI) would still be unhealthy if I happen to do intense workouts 6 times a week? I feel very tired during my workouts even keto adapted and electrolytes taken care of. Another thing, muscle building is alot harder on keto. Any input Dr.?

  47. How can I test glucose and Ketones at home? I don’t have weight to lose , maybe just 5 pounds but I want to do intermittent fasting for health benefits. Will try it how you recommended

  48. I lost 14 kg in 2 months, eating low carbs and IF 20/4 … Also Wight training+ short cardio 4 times per weak… Thx for all your information sir 🙏🙏🙏

  49. I did water fasting 21 day last year but my blood presure fall to 90/50 (my normal is 140/90) than i get scared and i stoped! Everything was ok during fast! I will do it again but i am litlle bit concern about blood pressure…

  50. Dr Ekberg, will u advice a breastfeeding mum to do keto? I'm already doing IF and I've lost almost all my pregnancy weight ( 5 more to go). I also strength train 3times a week.

  51. Thank you very much for this presentation.
    Question:
    Is it normal for someone starting Keto diet to spend 3 to 4 days without bowel movements?
    Or does one become regular after the beginning?

  52. "You don't have to eat so often [on keto]. It saves a tremendous amount of time to only eat once or twice a day." But cooking is my hobby. How am I supposed to enjoy cooking when I can only make one meal a day? 🙁

  53. I LOVE your videos.  Could you please explain the issues with taking Vit. D3?  A lot of people seem to think you’re throwing your life away if you are not supplementing (sometimes recommending 5,000 I.U. or every more), but recently I have consulted a naturopath who says that people are getting into a lot of trouble with over-supplementation.  D3 has an active and inactive form but the regular Vit D3 blood test only measures the inactive form.  The blood test could show its low, but the active is too high and causing problems.  So confusing.
    Thank you!

  54. How often should you check your fasting insulin? Also, is there a way to check it at home or is it always a lab test?

    Fantastic video as always!

  55. Thank you Dr. Ekberg . . . . everything is so explained and easy to understand. I have to do more fasting first to then incorporate more of keto w/IF – your videos are great!

  56. Once again awesome material. A question to test your fasting insulinrhow long should you fast. I’m new to this and can do the 16 hour fasting

  57. I started the 20/4 last Tuesday and am just a novice but haven't counted the content of what I've been eating but have severely dropped the carbs, I'm now in the 47th hour of what I plan to be a 50 hour fast and have never felt better in all seriousness…the dog walk at 25 hrs yesterday started with a bit of "wooziness" but that cleared and I haven't had one hunger pang since that point. A pint of water with ACV and a half lemon juice each day and lots of decaff green tea. I feel I could go another day but better not overdo this… when I break the fast it's on to full Keto diet….What a revelation this has been- thanks Dr Ekberg!!!

  58. Your videos are amazing, thank you for sharing your expertise and wisdom with us. My main concern is how to implement fasting with medications that need to be taken after food? I would love to do it, but have to take Metoprolol at 8 in the morning after a meal/milk.
    Do you already have a video on that topic? Is it possible to dilute HW Cream with water instead? Any advice would be greatly appreciated.
