One of the unsung heroes of practicing intermittent fasting is that by training yourself to run on your own fat stores, I have found that when I am in a situation where appropriate keto food is not available, I can effortlessly choose not to eat until I can get the right food. I did my first 5 day fast while my son was in the ICU for a week - and I had very limited options for keto food. I just decided to fast until he was out of danger. I drank water and coffee only for those days. Pretty sure it got me through one of the worst times as a parent.
I can go a day without eating quite easily now. Before, I was ready to go out and kill my own food if I went without for more than about 4 hours. Glad your child is well, as a parent myself, I can relate. Been there. Good luck. Let's keep spreading the word.
In the past the longest I did was 3 days and I was ok with that, it was comfortable. I’ve just come off a 4 day only because by day 2 and 3 I was feeling okay but by day 4 it was enough, I had not only decided I wasn’t going past that but my body was telling me “I’ve had enough, I need you to start a refuel again”. In nature I don’t believe we’d go for so long without food unless there was a real scarcity and as you say we were probably way better adapted to the scarcity if there was any. From now on I feel 3 days will be my max but it would be okay to do 36,48 to shake things up. I acknowledge that I have a food relationship to manage psychologically. I use omad and have kicked sugar and carbs to the kerb so my intake is at a bare minimum in things like milk, yog, kefir etc and I love my meat!!! I’m cleaning up my body and I don’t want nasty food in it anymore.😊Interesting and educational videos thankyou so much. Ps it does make me laugh when you swear and tell it like it is😂❤
Thank you for this video! I consider myself a carnivore veteran that has reached my weight goals. Although OMAD has become effortless, I now understand why my body is always telling me to eat when I do fasts over 24 hours. Duh...listen to your body.
Been doing LCHF for six months. Lost 50lbs and feeling great. However, when I think of my favourite cheesecake I begin to salivate and crave carbs, sometimes almost to the point of tears. Pretty sure that makes me an addict.
I completely understand. I've been doing LCHF for just over a year, and I have felt the craving this hard before. I am definitely an addict, you sound like you are, too. But. You are NOT alone.
WOW ... this was an eye opener! I have slipped back into old habits over the last couple of weeks. Getting back into it with one meal per day, nothing after 7 or 8 o'clock. Thank you for this Dr. Cywes.
Everytime I listen to this guy I gain more knowledge of what needs to be done. I did everything wrong for many years, drinking, smoking eating everything in the comfort food category. I was in Vietnam, exposed to Agent Orange (weed killer) for a year. In 2018 the VA tests showed nodules in my lung, type 2 diabetes, high blood pressure. I began the routine of IF, cut the carbs and SUGAR from my diet. Last year testing revealed the nodules were gone, I am almost below 6 AIC, lost 15 pounds and feel better than when I was forty, 74 now. It’s hard to believe what you eat can have such a dramatic effect on health. You almost have to do it to believe it. But, believe it. I am indebted to Doctors like this one. After all, isn’t an honest Doctor all we really want from the health system?
I have been in time restricted eating for many years. What I learn is that the best thing what people can do for overall well being is to try to eat all calories earlier in a day and fast through the rest of a day. I feel the best when I finish eating till around 2 pm.
me too! was eating large meal in the afternoon, and was having not enough time to digest everything before going to bed. I switched to eating lunches (12-2pm) and it works wonders!
Years ago, I begin this journey of nutritionally educating myself with Jason Fung. A few months back, I began furthering my understanding of all this with Dr. Cywes. Dr. Cywes takes this understanding to the next level. The information is now available if one wishes to seek it.
Another great point he makes is that it depends on where you are in your journey as to how often you should fast! We are all different, depending on where we are in this health journey.
I'm sure you're correct, but it's a dog imo. I wouldn't feel bad about giving some dog food. I would personally give real food supplemented with kibbles.
@@hoguejp supplement with kibble? That is like saying I eat keto but supplement with pasta. Commercial kibble dog foods always have rubbish in them. A quality whole food raw diet is absolutely best for your dog. They also poop less because they aren't getting all the crap. A bit like us really! We don't get constipated... we poop less because we eat less unnecessary materials
My target is to get rid of toxic stuffs in my body that has been there for years. The most number of hours I did is 24 hours but I also did it with exercise and healthy diet of meat and veggies. It is hard to get rid of my alcohol consumption but I was able to. I am now 149lbs from 172. My height is 5’7” so I’m in the proper BMI range. Intermittent fasting is a challenge but it could be the best sport that I ever played. Now I am not afraid to consume meat and eggs cause I am eating veggies too. No more bread or carb for me.
I was near a Sam's club the other day and went in to see if there was anything I needed. Ended up walking out discusted at every isle full of processed junk food crap.
Thank you. Needed to hear this. I lost 115 pounds using intermittent fasting. I’ve become far too dogmatic. Reached 9% body fat and had it stuck in my head I had to keep fasting/OMAD/starving myself. Needed permission to return to a normal healthy relationship with food.
This is soooo good! Personally I've been playing way to long with intermediate fasting (years) once I began consistently adding extended fasting throughout my week 😅things just CHANGED!
I'm a very happy, healthy Vegan ... Eating a whole foods, Good fats, NO processed, No sugar, only supplement with B12 ... Eating OMAD... and LOVING it... What a wonderful lifestyle... 65 feeling 45... I do a 72hr Fast once a month, for Autophagy etc... Never hungry and never felt so good... Thank you Dr Jason Fung et al
Would also suggest watching Prof David Sinclair ... He explains the science very well and in more detail than Dr Cywes ... but he is a biologist who is a professor of genetics and co-director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School. He is known for his research on aging with a focus on epigenetics. He is an officer of the Order of Australia. So probably far more qualified ?
It's like you are in my head and you are reading my mind. About a year ago I started IF to stop my self from snaking and to lower my insulin. I called it for myself "smart fasting" 😁👍
Please do more videos for those of us that are now insulin sensitive but still practice IF. I have lost 160 pounds and am maintaining the loss with exercise and IF. Although I eat about 2000 calories in my OMAD (whole foods ketovore) I still can't stop my hairloss which tells me something is off even with the healthy lifestyle.
Maybe its a copper deficiency (trace mineral), there is a really great discourse entitled "DEAD DRS DON'T LIE". This is an interview of a Farmer turned Vetinarian turned Medical Dr.
@@brianchv3661 thanks for the idea! I looked on my food tracking app and it looks like I get more than enough by eating nuts but who knows if there's more to it.
I don’t intentionally fast, just eat when hungry 1-2 times a day. I will be braking from that a few times in next 3 wks cuz I have meetings with friends for lunch at 11:30 - 12:30 and I normally don’t eat til 2:00 - 4:00 and again 7:00 - 9:00. Hope it doesn’t mess me up. I’m thrilled with my recent lipid panel and CMP. No A1C until Nov.
Yeah, I did the rolling 72 hours and 48 hours for over a couple of months then went back to eating one to two meals a day and then skipped a day here or there or sometime just skip a couple of days. And I was working out during my rolling fasting days as well, not with the same intensity I did when I eat on consecutive days but I did work out. So you're doing the blood test which is a good thing, what you might want to do is get in touch with other groups like Cole Robinson's group or and others because there are people who are doing really well on those rolling fasting diets.
I sure needed this talk! Don't know how I missed it until today. 72 yo female. I've been (more carnivore but some keto) for over 3 years. I have a 1 to 5 hour eating window, mixing it up from day to day. IR score < 25, HDL-C 78, LDL size 22.1, Small LDL-P 450 nmol/L but trigs 152, TC 529, HDL-P 30.1, LDL-C 420, LDL-P
Good to know because I am insulin sensitive and very healthy after 2 years of Keto. I am not keen on fasting in any case and also I would like to eat dinner once in awhile.
I knew I was doing well when I decided to go from a planned two-day fast to a three day, just after doing a 2.2 mile hike (which was about 7 weeks post-op total left hip replacement). Listen to your body. (And there have been fasts where I've stopped early, too).
I've been eating a low/no carb diet for years. I eat once a day and I feel clean and light. I don't suffer colds or flu, I don't feel deprived or depressed about what I eat or the frequency of my meals. I train my body, ipso facto my mind, using resistance and body weight. I have no need of prescription drugs. When people ask me about my lifestyle, this usually happens when I'm noticed not eating, I tell them what I don't eat; it's easier that way. I'll go into greater detail if the person shows an interest.
I agree that when we speak about fasting this term is badly defined. We are talking about feeding and non-feeding, so cyclic feeding [1], feeding duration [2], and total feeding over an extended period [3] (yields average time on a cyclic basis). I am diminishing the fasting viewpoint because in my view these three noted "factors" need to be addressed. What is the benefit of cyclic feeding? Is this even important? What is the optimal time for a feeding session? And how many hours of feeding are actually needed in, say a 7 day period. I am postulating that less than 30 hours per 7 days is problematic, but also feeding hours greater than 60 hours per 7 days are sub-optimal. So bang, 40-50 hours per 7 days. Mix and match as you will.
Thank you Doc! My Doc. No bs. 60 yr old male. 22 months, 460-324 today. Bad hip, was so mentally and physically, metabolically broken, only done 48 max so far. Love the learning you preach and am a testament that it works for me a human. No chest meals. Animal. Cheese, no sugar no carbs “ the human bodily doesn’t need them, the liver makes all you need”. Damn. Thank you sir! Another year and then, ? Spandex baby! Hahahahahahah
Very informative. I'm mid way through so I have done a couple of 24 hour fasts. I do listen to my body and sometimes cut them short because either I don't feel good or my stomach starts growling.
My thyroid hormones drop significantly and i have significant hair loss along with checking my blood sugar drops to 55 and I literally shake and feel like passing out after 24-36 hours :( Easily become dehydrated which in turn effects from kidney function as well. Electrolytes are highly sensitive as well! 🆘
Excellent presentation. Super logical and obviously comes from a place of wisdom upon the subject. Dr Cywes, could you speak to how you might handle a dirty carnivore diet if you have the beginnings of kidney disease? It still seems to me that a carnivore/keto diet is still the healthier approach because of its positive effects on Blood pressure. Even if its higher in phosphates. But I would love to hear what you think on the subject.
Maybe try going higher fat low protein. Some people eat too much protein and stress their liver too much when their liver isn't in great shape already. Maybe 60-85g protein and up to like 200g of fat to get the caloric requirements given you don't need weight loss. Easiest way to do that is cook bacon and scramble eggs into that without draining, it takes up all the fat so it's not free liquid. You can also have pork sausage meat which is usually very fat heavy, a You can add butter or tallow to ground beef that's too lean, or put it on steaks or pork chops, etcetera. Just up your fats if your liver shows raised numbers.
If someone can do OMAD and eat non essential naughty carbs, then what is the problem? Each to their own. That said (caveat) what is preached here and what Prof Noakes advocates (+ many others) is sound advice.
I joined the ketogenic life style 18 months ago and have incorporated intermittent fasting. On most days I’m OMAD. I have lost 30 lbs but that happened in the first seven months. I would love to accomplish my goal of just 10 more lbs. it’s been extremely difficult. Can’t seem to get it off even switching thing up a bit including extended fasting. Good news though. Metabolic syndrome CURED!!
Thank you for explaining that lean mass people shouldn’t fast too long!! if you do, you’ll lose your hair among other things!😊 not many tell people this… Lean mass people don’t do long fasts!!
I watched a video where the presenter suggested occasionally eating a low-GI type of starch like rye toast, and have some butter and a good chunk of cheese to that. The argument was that the fat will result in the glucose from the bread being released more slowly because of the butter and cheese.
Excellent presentation. Is there a body fat % rule of thumb, where it's not advisable to IF? I'm reasonably lean and lift weight. When I eat just twice daily (16:8), I feel fine. However, I tend not to gain any strength or muscle mass. This changes when I insert a 3rd daily meal.
Hmm, I too am lean and fit. Same scenario. Guessing the 3rd meal will make me gain strength! Presuming that’s what it does for you? I also notice if I go overboard with protein, (those darn Keto apps ratios) my BUN goes up so I scaled back to about 100 g or so. I’m 6 foot 156 pounds at age 52
@@ansebbianslip I've been lifting most of my life (I'm 60). And I follow numerous YT fitness channels & so-called experts. General agreement by virtually all is that IF is less than ideal. If your objective is to gain lean muscle mass. I strive for 1g of protein per 1 lb. of bodyweight. Almost impossible to accomplish that in just 2 meals. I simply can't eat that much food (I supplement with shakes). I have tremendous respect for Dr. Cywes, but I'm sure he'll disagree with my comments.
@@williamdahl3318 I thought the Dr. said that if you are insulin sensitive and fit that you might need to eat more than 1 to 2 times a day and that fasting is not needed. If you are in good shape you have healed your carb-addicted and hormonally-unbalanced body. So the extra meals and the more serious intermittant fasting would essentially not apply to you.
surprised to hear cywes say an extended fast beyond 24 hours isn't his recommendation for veterans who are in shape. i assumed there were still benefits via autophagy for such tenured omni-carnivores even if there is an elevated risk of some muscle catabolism.
And he said especially "for the slim ones," like me. I'm not sure why he singled us out. Why would my body eat muscle if there is fat available? I never lose strength when I fast, but now I'm a bit concerned about it. One thing I know is that I have never gotten sick since I started fasting, and being sick is a very direct way to lose strength.
When I finished my 10 day water fast, my blood sugar was 100. How can that be doc? I’ve done many 3-5-7 day fasts before that one and I felt 100% with 0 complaints of any kind. Could it be the body converting glycerin from burned fat into glucose?
Hi sir, I am following OMAD for the past two weeks (Male / 30age / 80kg) I tested my blood sugar an hour before my meal which was 78mg/dL and 2hrs after the meal its spiked to 161mg/dL. I ate 1cup of rice, 1 small banana, 3 boiled egg. Should I be worried here about the 161 level?
Hi dr Cywes and everybody! Please help for carb cravings! I am a woman, 52, lean, sporty. My whole life I had sleeping problems and gut issues like gaz and later also tendon pains and burning painful feet and restless legs and fatigue. I do keto and IF and OMAD since 7 months, I feel good, problems are gone. But every 5 or so days I suddenly get a terrible carb craving, I have chocolat or crackers with honey. Next day the tendon pain is back. Then I am motivated again and do keto and IF again and feel great. 5 or 6 days later the cravings come back. Get the chocolat, honey and crackers out of the house, I can not do it. I feel panic if I don't have them. When I get the craving I walk in the house like a bear in a cage, totally frustrated. Why can I go 5 or 6 days without cravings and why do they come back? I get the cravings when I am tired. I get tired from bad night sleep. I get bad sleep after sport (tennis and horse riding). I love sport but it excites me (I am very sensitive) and makes sleeping difficult.
@@thespear4083 Hi! Thanks! I eat lots of animal fat. Fatty meat and fish, fish oil, heavy cream and butter with my veggies, egg yolks, every evening as dessert I eat a big bowl of full fat sheep yogurt with mascarpone (50% fat!). I am discovering that I am sensitive to histamine. The histamine causes me lack of sleep (waking up in the middle of the night being hot and sweaty). And then being tired causes sugar cravings. Now trying to eat lower histamine foods and using DAO before dinner.

From one physician to another, one of the most balanced discussions. I wish every physician every where listens to it.

I could literally listen to you ALL day long, no joke. Amazing content, talking the truth to a whole new level. So refreshing.

Thank you for the video. It’s as if you knew exactly what I needed to hear. I’m so glad Dr Berry recommended you.❤️🙏
I knew I was doing well when I decided to go from a planned two-day fast to a three day, just after doing a 2.2 mile hike (which was about 7 weeks post-op total left hip replacement). Listen to your body. (And there have been fasts where I've stopped early, too).
Im crying happy tears because i found this channel today! 🥲🥰
Interesting conv, Dr Cywes.
When the fish in Finding Nemo finally escape and reach the ocean, they say, "Now what?" Thank you for acknowledging the, "Now what" for the veterans.
I've been eating a low/no carb diet for years. I eat once a day and I feel clean and light. I don't suffer colds or flu, I don't feel deprived or depressed about what I eat or the frequency of my meals. I train my body, ipso facto my mind, using resistance and body weight. I have no need of prescription drugs. When people ask me about my lifestyle, this usually happens when I'm noticed not eating, I tell them what I don't eat; it's easier that way. I'll go into greater detail if the person shows an interest.
aaaahhh ipso facto. Long time I haven't heard that expression. Thank you for that!
Great perspective. Makes total sense! Thank you!!
I agree that when we speak about fasting this term is badly defined. We are talking about feeding and non-feeding, so cyclic feeding [1], feeding duration [2], and total feeding over an extended period [3] (yields average time on a cyclic basis). I am diminishing the fasting viewpoint because in my view these three noted "factors" need to be addressed. What is the benefit of cyclic feeding? Is this even important? What is the optimal time for a feeding session? And how many hours of feeding are actually needed in, say a 7 day period. I am postulating that less than 30 hours per 7 days is problematic, but also feeding hours greater than 60 hours per 7 days are sub-optimal. So bang, 40-50 hours per 7 days. Mix and match as you will.
Thank you Doc! My Doc. No bs. 60 yr old male.
22 months, 460-324 today. Bad hip, was so mentally and physically, metabolically broken, only done 48 max so far. Love the learning you preach and am a testament that it works for me a human. No chest meals. Animal. Cheese, no sugar no carbs “ the human bodily doesn’t need them, the liver makes all you need”. Damn.
Thank you sir!
Another year and then, ? Spandex baby! Hahahahahahah
Very informative. I'm mid way through so I have done a couple of 24 hour fasts. I do listen to my body and sometimes cut them short because either I don't feel good or my stomach starts growling.
My thyroid hormones drop significantly and i have significant hair loss along with checking my blood sugar drops to 55 and I literally shake and feel like passing out after 24-36 hours :( Easily become dehydrated which in turn effects from kidney function as well. Electrolytes are highly sensitive as well! 🆘
Excellent presentation. Super logical and obviously comes from a place of wisdom upon the subject.
Dr Cywes, could you speak to how you might handle a dirty carnivore diet if you have the beginnings of kidney disease? It still seems to me that a carnivore/keto diet is still the healthier approach because of its positive effects on Blood pressure. Even if its higher in phosphates. But I would love to hear what you think on the subject.
Maybe try going higher fat low protein. Some people eat too much protein and stress their liver too much when their liver isn't in great shape already. Maybe 60-85g protein and up to like 200g of fat to get the caloric requirements given you don't need weight loss. Easiest way to do that is cook bacon and scramble eggs into that without draining, it takes up all the fat so it's not free liquid. You can also have pork sausage meat which is usually very fat heavy, a
You can add butter or tallow to ground beef that's too lean, or put it on steaks or pork chops, etcetera.
Just up your fats if your liver shows raised numbers.
If someone can do OMAD and eat non essential naughty carbs, then what is the problem?
Each to their own.
That said (caveat) what is preached here and what Prof Noakes advocates (+ many others) is sound advice.
So reasonable! Thank you.
So how often should we IF when we’ve become insulin sensitive and how often should we eat 2/3/4 meals a day? Thank you
Mix it up! Keep your body guessing 😉
Such great information! Can’t wait for each new video. Life saving stuff..🙌
How many days to wait in-between 5 day fasts?
Brilliant!🙂
I joined the ketogenic life style 18 months ago and have incorporated intermittent fasting. On most days I’m OMAD. I have lost 30 lbs but that happened in the first seven months. I would love to accomplish my goal of just 10 more lbs. it’s been extremely difficult. Can’t seem to get it off even switching thing up a bit including extended fasting. Good news though. Metabolic syndrome CURED!!
Any recommendations?
It's been six months since your comment. Have you lost the other 10lbs?
Thank you for explaining that lean mass people shouldn’t fast too long!! if you do, you’ll lose your hair among other things!😊 not many tell people this… Lean mass people don’t do long fasts!!
I love listening to you, always to the point, and just the best info.
I watched a video where the presenter suggested occasionally eating a low-GI type of starch like rye toast, and have some butter and a good chunk of cheese to that. The argument was that the fat will result in the glucose from the bread being released more slowly because of the butter and cheese.
YOU ARE AMAZING DOCTOR THANK YOU SO MUCH
Was going to ask if black coffee is ok during an extended fast. But now I hear that I should not do it. Fine with me. Great talk.
He said coffee is fine 🤗
Thank you, Dr. For yet another fantastic video!
Excellent presentation. Is there a body fat % rule of thumb, where it's not advisable to IF? I'm reasonably lean and lift weight. When I eat just twice daily (16:8), I feel fine. However, I tend not to gain any strength or muscle mass. This changes when I insert a 3rd daily meal.
Hmm, I too am lean and fit. Same scenario. Guessing the 3rd meal will make me gain strength! Presuming that’s what it does for you? I also notice if I go overboard with protein, (those darn Keto apps ratios) my BUN goes up so I scaled back to about 100 g or so. I’m 6 foot 156 pounds at age 52
@@ansebbianslip I've been lifting most of my life (I'm 60). And I follow numerous YT fitness channels & so-called experts. General agreement by virtually all is that IF is less than ideal. If your objective is to gain lean muscle mass. I strive for 1g of protein per 1 lb. of bodyweight. Almost impossible to accomplish that in just 2 meals. I simply can't eat that much food (I supplement with shakes). I have tremendous respect for Dr. Cywes, but I'm sure he'll disagree with my comments.
@@williamdahl3318 I thought the Dr. said that if you are insulin sensitive and fit that you might need to eat more than 1 to 2 times a day and that fasting is not needed. If you are in good shape you have healed your carb-addicted and hormonally-unbalanced body. So the extra meals and the more serious intermittant fasting would essentially not apply to you.
@@electricmayhem8147 That makes perfect sense. Thanks for the comment.
thanks Dr C
Great video like always !
surprised to hear cywes say an extended fast beyond 24 hours isn't his recommendation for veterans who are in shape. i assumed there were still benefits via autophagy for such tenured omni-carnivores even if there is an elevated risk of some muscle catabolism.
And he said especially "for the slim ones," like me.
I'm not sure why he singled us out.
Why would my body eat muscle if there is fat available? I never lose strength when I fast, but now I'm a bit concerned about it.
One thing I know is that I have never gotten sick since I started fasting, and being sick is a very direct way to lose strength.
As a long term carnivore, I prefer to do IM to allow my intestinal track the time to repair and heal from the previous meal.
When I finished my 10 day water fast, my blood sugar was 100. How can that be doc? I’ve done many 3-5-7 day fasts before that one and I felt 100% with 0 complaints of any kind. Could it be the body converting glycerin from burned fat into glucose?
Liver was using up its fat stores
That was fantastic! Thank you!
How can I drink coffee while I'm fasting? Is stevia ok? I can't drink unsweetened coffee. Can I add heavy cream to coffee while fasting?
Yes
Great content
Hi sir, I am following OMAD for the past two weeks (Male / 30age / 80kg) I tested my blood sugar an hour before my meal which was 78mg/dL and 2hrs after the meal its spiked to 161mg/dL. I ate 1cup of rice, 1 small banana, 3 boiled egg. Should I be worried here about the 161 level?
Thank you.
I love your no-nonsense framing of things.
Hi dr Cywes and everybody! Please help for carb cravings! I am a woman, 52, lean, sporty. My whole life I had sleeping problems and gut issues like gaz and later also tendon pains and burning painful feet and restless legs and fatigue. I do keto and IF and OMAD since 7 months, I feel good, problems are gone. But every 5 or so days I suddenly get a terrible carb craving, I have chocolat or crackers with honey. Next day the tendon pain is back. Then I am motivated again and do keto and IF again and feel great. 5 or 6 days later the cravings come back. Get the chocolat, honey and crackers out of the house, I can not do it. I feel panic if I don't have them. When I get the craving I walk in the house like a bear in a cage, totally frustrated. Why can I go 5 or 6 days without cravings and why do they come back? I get the cravings when I am tired. I get tired from bad night sleep. I get bad sleep after sport (tennis and horse riding). I love sport but it excites me (I am very sensitive) and makes sleeping difficult.
You need more animal fats to help with sleep and cravings.
@@thespear4083 Hi! Thanks! I eat lots of animal fat. Fatty meat and fish, fish oil, heavy cream and butter with my veggies, egg yolks, every evening as dessert I eat a big bowl of full fat sheep yogurt with mascarpone (50% fat!). I am discovering that I am sensitive to histamine. The histamine causes me lack of sleep (waking up in the middle of the night being hot and sweaty). And then being tired causes sugar cravings. Now trying to eat lower histamine foods and using DAO before dinner.
@@KirstiCheetahh I hope you get better sleep soon. 🤗
@@thespear4083 😃 Thanks!
Always very informative videos 🙏🙏🙏👌
