It took me a year to heal ir and be able to do 23/1 dont give up! Dr. Berg is right!

Dr. Berg is spot on with this concept. Once your body acclamates to ketosis, you are golden. Electrolytes and proper vitamins and minerals are key. I do at least 20 hours a day fasting and I am able to do long endurance rides on my bike whilst fasting with no issues at all! OMAD is great! 🙂

Going by the comments, there seem to be a LOT more women who struggle with this. I think this needs to be acknowledged and addressed, there is quite clearly a physiological difference in the way women handle fasting compared to men.

Don't go too fast into the fast guys

Your videos are so helpful! Trying to reverse my diabetes, and get to a nice healthy weight. I’ve been on Keto for 11 weeks now, and the first time I tried a 16 hour fast, I felt awful! I was weak, dizzy, and had an awful headache, and after I ate, I felt nauseous. I waited a few days and tried again, and I felt great the whole time except for cravings which I believe is mental more than actual hunger. I’m trying to up my game with a 24 hour fast after way too much fat the day before, and I was feeling the yuck again, so after I seeing this I drank some salt water, and took my b vitamin supplement, and I feel some relief. 3 more hours to go, I can manage this! Thank you 🙌🏼

Cut the wheat altogether. I only have one meal a day but if I somehow eat any type of dough, it will screw up the whole process

Thanks Dr. Berg! Down 60 pounds in three months. Your advice obviously works. Never felt better.

I was feeling faint yesterday and just tossed some sea salt in my hand and ate it...I dont know if its possible but I felt better with in 3 min.

Adding a table spoon of nutritional yeast to my last meal before fasting has helped immensely in prolonging the time of my fast.

I’ve notice when I was doing IF I was feeling lightheaded, weak and tired . But when I started taking one teaspoon of Himalayan salt every day I felt my energy level rise and all those symptoms went away , now I can fast much longer

Best thing about you that show your honesty is you explain stuff before selling anything

Take some salts (Potassium, magnesium, and sodium) and some vitamins and trace minerals to give you a boost.

Thank you Dr. Eric berg😍 You're my favorite you tube doctor💙

I naturally used to keep this diet, not being hungry, eating once a day... didnt seem difficult at all. didnt really know it was healthy either, cause people said i should eat five times a day.

Before starting 18:6 I used to be 'starving' by lunch time and felt dizzy. Just day 20 of 18:6 and already feeling better. I think hormonal changes for women has some influence on how we are feeling during fasting.

I'm currently water fasting, now it's been 1 and half day, feeling great, light, free and clear ❤️

I have been fasting about 40 hrs and I’ve been very dizzy and feel like i could pass out. Took some pink sea salt much better.thank you

Perfect Dr. Berg. You've mentioned parts of this strategy randomly in other videos so I've followed this advice for 6 months and suddenly, yesterday, I achieved a 24 hr fast without torture - yay! So for newbies, it's true. I adjusted to 2 meals a day (skipping breakfast) after a couple months, and shrunk it to 20/4 after about 5 mths and now at 7 months I'm doing great. To do the 24hr fast I drank lots of water with NoSalt for potassium and Redmond's salt, also magnesium. Never saw a doctor thru this for testing but all the signs and symptoms were that I was IR and heading toward fatty liver. Thank you Dr. Berg!!!!!

I do really like the content of your videos. Thank you.

You always reinforce my trust in you. I thought you were going to advise a big glass of water or a couple of spirulina tablets. Instead you advised to listen to your body - a smarter, safer, more logical route - rather than to be m o r e drastic. You're consistantly the best Dr. Berg!!

You don’t need to go beyond 20 hrs. 16 hrs minimum. Exponential Benefits between 16 and 20 hrs though. You will start to feel amazing between 16 and 20

Oh that’s so good to know! I’ll build up to it instead of giving up because I felt bad.

Dr Berg ..may God bless you for giving free advice to keep healthy. You have a big heart and I pray for you and your family to have a healthy happy long life.♥️

Dr Berg, is pink Himalayan salt also good? I read that sea salt (Celtic salt) is contaminated with plastic from the ocean.

Saving the world one video at a time. I look forward to your content every day; so helpful.

Right on time. Doing a longer fast this weekend. Will make sure to get all of those electrolytes in. I will never forget one day you said potassium is the most important electrolyte. Helpful as always 💕

Thanks, Doc, you’re the best, fastest at answering questions for us to succeed at KETO!!!

Thanks! this video came in a perfect time for me. I started one meal diet since two days but today I am feeling so week and energy drained.

i fasted for 36hr...then in office i started to feel cold. and after an hour i passed out for half a second in my chair.....i immediately rushed and had a sweet tea and broke the fast......i made the mistake of only drinking water during the fast...no salts. Muscles were also vibrating as i was having the tea. probably due to low sodium again. Will try again with proper guidance now. thank you Doctor.

I'm on 44 hour fasting now, thanks to your tips, I don't feel horrible! Viva keto and Viva Dr Berg :)

42 hours of fasting so far and still not feeling weak. I always have some salt with me.

Another Great video thank you Doctor for sharing your knowledge with us👍🏻☮️ You brought back my faith in humanity since I found you

I am in day 6 of a water fast. I cannot say I have so much more energy as some claim and I am not sure about the sharpness of mind. With this said, I am getting through having never gone this long on water fasting. I have been working out a bit, I have cooked for my husband, I have been to food shops, and I have not fallen off the wagon. I do feel very cold in the evening only. Rest of the day I feel "normal". Really would have liked to have that extra woomf everyone is talking about. I do take all the supplements and a tea spoon of Himalayan salt. A few days allow one black coffee with a tbs of double cream. Lemon/ACV/Cinnamon powder water - a pint - twice a day (morning and evening, warm water). Thank you Dr. Berg if you have any insight on why I am not "flying".

I am regularly doing 16/8 IF and Keto diet for about 3 weeks already but yesterday I tried 20/4 hours, but i really felt weak, but I am glad to have reminded about this and never give up.. I am 75kilos but I am glad that I am now 67.5 kls and I am more motivated to really be healthy first before losing weight.. Tnx Dr. Berg😀

Did 24-36 hrs. Pink salt and electrolytes really helped! Also took a slow release 1,620mg potassium citrate tablet to help.

this was a GREAT add to your overall output, THANKS SO MUCH Dr. Berg, I see a light at the end of the tunnel) Hopefully it isn't an oncoming train..

Please make a video on how to refeed after fasting

It can take months to fix but keep going - An example for me was shown in my recent full blood tests (all well within normal range). HDL 3 years ago was 31 and today it's 62 All by following Dr Bergs (and others) practices for the last 17 months- I eat upto 15 eggs a week now - 3 years ago I was lucky to eat 2 a month- lDL out of interest is at 112. So by increasing FAT (properly) fasting and improved diet I've cut the risk of heart disease -

Why do most people who advocate IF recommend skipping breakfast? What's wrong with skipping dinner, or skipping lunch & Dinner if doing OMAD?

MCT oil and vitamin B will break the fast tho 🤔 I know cause I ran the Ketone and Blood sugar tests

Us Muslims been doing it for years, going from eating regularly to 15 hours* First few days are usually hard and then your body get used to it

Been doing the 16 / 8 intermittent fasting for more than a year now .. Results have been nothing but AMAZING ..Not just psychically but also mentally .. I have never felt as sharp as I do now , thanks to putting LESS food into my body .. On top of that , I went cold turkey and quit alcohol and coffee all together and decided to get up at 5 am each day and hit the gym .. Life truly feels amazing ... ☺️☺️

I’m going on my 4th day of fasting with only water and I’ve been running a fever and body aches and still feel hungry. The fever is down from 102 to 100.5, but I feel terrible. And I’m cold. I’ve read that fever is not uncommon. I’m hoping day 4 breaks into the clarity and lightness and overall greatness so many talk about!

I found that the easiest way to build up to 20 / 4 IF is to sleep for as long as possible. ...eg Friday, eat by 6pm....Saturday have a good laying until say 10 if possible. ..then have a black tea or coffee. I then cycle around 20 to 25 miles and then have breakfast at say 2 or 3pm and finish your evening 2nd meal around 6pm that day and the same for Sunday.

That’s always a really great information and explained really well! Thanks dr berg 💕😍

Dr.Berg ... You are amazing !.. I have learned so much from you .. just want to thank you.. your content is always interesting , informative and above all its correct ..

Nice! Fasting is something that has to be eased into when your body is ready. It's really hard to fast before you are fully fat adapted and your body has healed some.

With the greatest of respect BUT women, especially - and even more so for older women - when eating at 6 or any time after - have a high chance of experiencing many negative effects, including exacerbating GERD and sleep apnea, insulin resistance and weight gain .... ugh !! this due in part due to food being still in the stomach even four hours later when going to sleep. If health seekers experience these conditions associated with eating late in the day, patently they would greatly benefit from making their 'food window' much earlier in the day. I do, but although I can't remember where I heard this advice it was in a great video along with all the metabolic reasons why - including the fact that women's metabolism is different from men's, and from younger pre-menopausal women also (of course). I'm 75 !! and one of the best things for getting into fat burning is satisfying physical exercise in the outdoors

You need electrolytes, food grade epsom Salts, potassium and sodium chloride.

I'm not IR, do keto, recently did a 7 day fast, & was so weak it took enough energy just to go downstairs. I took about 5 grams of Redmond's Real salt, some KCL, & Mg oil daily. I ended up having 3 cups of black tea for 3 days just to get a little more energy. I know people say that doesn't break a fast but it has calories so to me it seems like it would stop autophagy which is why I fast to begin with. I'm hoping for different results next time but don't know what else to do differently. I did just start a B complex so maybe that'll help.

We do this in Ramadan.

Dr will grab 3 millions soon. Keep up your good work.

Great advice as always! Listening to our body is gold!👌 ✌🏼😎👍🏼

You're a good man dr berg

Hello doctor, you are my inspiration, please can you make a video about 48 hour fasting (OMEOD) one meal every other day, when I have my meal, its filled with protein, and fibers, sometimes i find it hard to consume fiber, so I take vitamin B12 pill and I use nu-salt for potassium ( as u always say that potassium is important) and i take multivitamin pill daily, I oftenly drink unsweetened almond milk and eat psyllium husk powder My keto deit timeline : Normal keto deit three meals a day After about two weeks I started OMAD After two months of OMAD i switched to OMEOD ( about a month now) Feeling great, no hunger, sometimes I feel hungry and I crave proteins Thank you

I normally go on how I feel. I guess that's too simple

Thank YOU DR BERG! I love your videos, I am in London, Ontario.

Ahhh this is the video I need! Felt like fainting today after 19 hours fasting.

Great info Thank you Dc. Berg

Doing Breakfast around 10-11am, and Lunch between 4-5pm, with water-based drinks in the middle is most sustainable.

Been doing 16:8 for almost 4 years. But last month I felt like I needed more because I started to get UTI symptoms, so I fasted 18 for 4 days, pain burning and discomfort was completely gone! I knew I needed to stick to 18 hours so I could repair even more damage and then one day I “accidentally” fasted 20 hours because I was busy and I literally felt a change in my body and my skin felt amazing, I’m on week 2 of 20/4 fast and never going back, I feel on top of the world, no cravings,little hunger and lots of energy!

Gracious, selfless message. (why you are blessed) Many thanks, Bonnie

Dr. Berg, in one of your videos on KETO, you suggested. ... If you feel HUNGRY, eat more FAT. IF you feel BLOATED , reduce FAT. I am facing both these symptoms , what to do? Your electrolyte powder is not available in my country

EXCELLENT PRESENTATION VERY INFORMATIVE

Went from 16:8 to OMAD. No fainting feeling, but a stabbing, blinding headache. So much so, I went back to 18:6

I needed this so much!!! Thank you Dr Berg!!

Its quite a challenge for people who are busy working to do 20 hours fasting everyday...heck the 16 hour itself is a bit difficult depending on your days...u have to plan in advance if ur days are all spend outside for work...

This works! I rarely have breakfast but tend to 'over eat' in the evening. I work out on an empty stomach and feel the most energetic, it's only after I have had a meal in the evening that I feel tired.

Feeling totally tired and cranky. It looks like I can do 20:4 every day but not without these crazy side effects. I did go from eating multiple times a day to 20:4. Feels like PMS symptoms.

I’ve fasted for two days and felt fine just tired, I’m gonna try day three tomorrow

24 hours in and I get extremely “can’t get up the stairs” weak

Yes, I was having this problem, feeling weak and faint, especially upon standing. That's not unusual for me, orthostatic hypotension, and it's happened since I was a kid. However, while fasting for extended periods (20+ hours) it was happening every time I stood up, even after briefly bending down, as opposed to after sitting or lying down for awhile. It was becoming annoying because I was doing a lot of housework and it was slowing me down. I also have normal BP, even thru 3 pregnancies it never got high, so I wonder if my BP falls a bit low when I fast. I also wondered if magnesium/potassium powder that I was using was lowering my BP even further.

Hello can you please make a video on how to refeed after 20 or more days ‏of water fasting🙇‍♀️

Ps Your live Q & A was amazing 💙 Love seeing you and your lovely wife work together ❤

I been doing keto for 2 weeks now, I only have 2 meals a day but I have a lot of headaches ☹️ I am not a person that usually gets headaches can someone give me an advice on what to do or eat? Thank you 🙏

good tips. i inadvertently fasted for 34 hours and was so weak.

I did 21hrs today (prev. between 16-19 hours) and suddenly 10 minutes before the break, I almost fainted .. getting cold sweat a lot and my eyes gets blurry .. just finished my meal and tried to find out what happened to avoid similar thing happened tomorrow. Thanks Dr Berg.

I don't feel weak or faint but I do have severe pain in my belly, on the right side, radiating to the back. I tend to break my 24 h or 36 h fast with bone broth or avocado. Once I broke the fast with blueberries and it was the worst pain ever.

I luv this man.

Thanks Dr Berg, I'm gonna try that👍thanks for this video😊

I passed out yesterday. I've been doing strict keto and 18:6 for one month and I feel great, but I feel dizzy if I get up too quickly. I tested my bllod pressure and it's a little bit low. Doctor told me to have more salt and sugar if I feel like this; for now I'll stick with more water and salt.

I’m belting out that infamous line from The Greatest Showman, “This Is Me!” Seriously. This Is Me! I can’t go more than 22 hrs w/o snapping at everyone that I come in contact with:(. I may or may not be hungry but my mental state deteriorates terribly. No mental clarity going on here even after 18 mo of Keto. Thanks for giving me permission to go back to 2 meals a day!

Lay down and deep breath. Idk what to do really but this helped me a lot 💙

Can we take any salt in the fasting window without breaking the fast?

Thank you

Ok, see my mistake now. Wanted to do a 72 hours fast instantly after 20/4 for a few years. Definitely not recommendable..

I’m almost at 40 hours and it’s been like climbing Everest 😓 unbelievably weak and faint zero energy. Drinking water, pink salt ACV green tea and just one coffee. I keep hearing ppl talk about this amazing energy and euphoria and I’m just not there. I’m a regular intermittent faster and I eat fairly healthy so not sure what’s going on with my body at this point but it’s far from comfortable 😓 I wanted to do the 72 but going to push for 48 because I can’t take much more of this 😩

After fasting more than 24 hours I always have Diarrhea, has anyone same problem?

Fasting for days made finally lose weight and i feel great

Dr Berg...does your electrolyte blend break a fast

Thank you Dr Berg, I’m actually feeling so much better 23.1, we appreciate you

Thanks for the information. I really need to keep up with the night fasting. That is the hardest for me. I manage very well to fast during the working hours but when I arrive at home, it is so hard to not snack after dinner. I will add MCT oil ... maybe will help me to fill more satisfied.

Thanks Dr. Berg; your videos helped me change my life . I (50 yr female) reached my goal weight by losing 45 lbs and maintaining for the last 4 months doing 17/7 IF and healthy keto. Recently I feel lightheaded before breaking my 17 hr fast .. why?

Thank you Dr Berg. By the way, I start feeling weak and faint even at 14 hours of fast. And, I've always been wondering if there are more people like me : I become really hungry at 7 or 8 am already. I see many of my colleagues don't eat breakfast because they " simply don't become hungry before 11 or 12." Some of them even have their first meal only when they get home from work. They DO have coffee in the morning and that's smth I don't do. I mean, I never have coffee. For me, it's impossible. I just have to eat lets say, before nine. Why someone's metabolism or whatever is that way, and mine is like this?... Just wondering...

This hasn't happened to me, yet, thank goodness. But I do have half a teaspoon off pink salt in my ACV drink in the morning with lemon, thus only needing another half a teaspoon or so in my OMAD meal for the rest off the day, seems too work for me so far. Must be scary though. Thanks for sharing this important information with us all, & take care to. ❤🙂🐶

We just had a large family event last weekend and at some point during that time, my 80 yr old diabetic dad told me his blood sugars were fine but it is his kidneys that are now a concern. He said at his last appointment the doctor said he is now Stage 3, and that his kidneys are not filtering, and next stage is Stage 4 which means dialysis. He said he can have absolutely NO salt or sodium. I am confused about this because I did a long term cleansing fast a couple of months ago and salt (I used Redmond's Real Salt dissolved in water) helped me through it for my minerals or I couldn't have made it. It was very hard and I have done cleansing fasts before, though I admit the last time was over 15 years ago and I am now 56 yrs old. I don't want to say the wrong thing to my dad because his health seems so borderline critical and I don't want to take anything for granted. I understand how all this works with what you say, Dr Berg, if a person is operating from a position where they just need to clean up their habits for good health. But I don't know how that works for a 80 yr old in my dad's situation. Could you please have a video about this? I don't understand all of this for a diabetic man of his age with filtering-challenged kidneys and not being able to have any sodium whatsoever.

Him and Dr Yahki are the BEST!

I use Himalayan salt, is that a good substitute for sea salt?

Dr. Berg can I please contact you?

i tried a 36 hr fast a month or two ago and got a splitting headache at about 20 hrs so i just had some cacao with mct oil, probly some sea salt too and i was fine until next morning. wasnt even hungry for bf but had bulletproof coffee anyways. probly could kept going to 40 to 48 hrs easy.
