Ep:306 FASTING ESSENTIALS ON A KETO-CARNIVORE DIET - FACTS V INTERNET NOISE

[@johnthomas753]

At 50, cutting carbs and no sugar has been a game changer for my high blood pressure, better sleep and feeling better than ever !

[@farmer_donny]

I began intermittent fasting about 40 years ago. I was an electronic engineer and like everyone else in the department at about 11 am I got peckish and a slight tremor to my hands. I noticed that on mornings when I was in a rush and didn't have a breakfast (usually cereal) I didn't get the tremor or the peckishness. So I stopped having breakfast and never had this problem again. I recently discovered this is called intermittent fasting and this has also led me to go keto/carnivore.

[@ItalianGoneCarnivore]

In order to get my life back, I pushed away the plate. I fasted for 48 hrs every other week and gave my organs the break they so desperately needed. I usually dont eat for 18 or more hours each day. 186 lbs. DOWN And currently carnivore (meat, eggs, little cheese).. I got my life back! I just finished my first 48 hr fast since hoing carnivore. It was too easy! When youre in ketosis for as long as I am, its just easy! Another great video. Your content is extremely valuable to me and I am so grateful for you. Our next video visit is the end of August..cant wait.

[@FERF3275]

This is one of the best common sense videos I have watched on the topic of fasting. You convinced me to fast 5 days instead of 7 days. Thank you, doctor.

[@alexbolotin8899]

100% agree with everything. Dr Chaffee says the same thing. Eat until satiated, then don’t eat until hungry again. Carnivore makes this very easy. 3rd week in, already float between OMAD and dinner every other day. Couldn’t get me to eat during the day

[@LTPottenger]

Broth and pot roast are great for breaking fasts. So is heavy cream and butter.

[@loriwilson-n9t]

Yum! Pot roast! Must be hard smelling it cooking though…

[@hollybishop484]

I like eating lol, but I also like the way fasting makes me feel. So I've learned that to fast, I need to do a 24 hour fat fast, then a 48 hour fast follows naturally.

[@loriwilson-n9t]

Yeah 👍 fasting definitely cuts inflammation down more if you’re in pain like me. I sometimes wish I didn’t require food…

Thank you looking forward to hearing how to break a 5 day fast. As I have become Carnivore I now break my fast with a smallish Carnivore meal. I used to do salads but now realize protein is what is most urgent.

[@loriwilson-n9t]

Yuck. Salad. That crap is like putting poison in your empty body with fake nutrients because most nutrients are not bioavailable. Thank goodness you quit doing that.

[@IDNHANTU2day]

Very interesting way to look at eating. Storage and utilization. Balance that, and that's a lifestyle.

[@pragmatic111]

Agree! When I heard you talk about what a carb addiction looks like OMG. That was me!

[@Oldbroad1]

I start to get a little “peckish” after 20 hours and I get anxious about doing something stupid. That’s been the case with so many of my efforts. So I allow myself to have a boiled egg or a piece of cheese, a slice of leftover chicken and then I’m calmed down again and I can make it till evening time when I have my dinner. I’ve only been doing this for 7 weeks. I’ve lost over 20 pounds, my blood sugar is coming down, I feel great! I’m just not sure I can go a full 24 or 36 hours without eating. Why risk it when I’m already doing so well? Bottom line is I don’t really like being hungry. I know my ancestors had to do it but I am doing the best I can. ❤

[@Straightdeal]

I can do 24 hours without problems, one meal around 18h30. I do not like to go further, sleeping on an empty stomach normally means I won't sleep well. But during the day I don't have a problem.

It’s fine, do what makes you feel better

[@SueSchalk]

It's something you have to work up to.

[@martinlang9615]

As Dr said, have the timing right: feel content within yourself, minimise stress give yourself the best start. It’s no big deal if you find that this time it didn’t work out, just try again another time when you are on a high. Your body will thank you and you will start to love it over time. Then it’s easy

[@jennie9]

It's working and you're comfortable with it, so keep doing what you're doing. If you eventually become unhappy with the results you're getting or your thinking shifts, you can try going a bit longer then. Don't stress about it now.

[@RiteOn]

After eating the SAD, hunger becomes a trigger; so worry about being hungry becomes overwhelming when considering "fasting". But eating protein and fat creates an easy fasting, automatic fasting state. If you eat just when you are hungry, and to satiety, you will not overeat.

[@robertcywes2966]

Ketosisfirst then fasting easier to enjoy

[@bradellison1345]

Did keto, lost 145 lbs. Concerned how fast weight came off. Hunger nonexistent. Lost some muscle mass. Gained all the weight back once I got back on the carbs. Got cancer, did chemo and now trying to take weight off again and it is much harder since poisoning myself. :) Wondering if I have an enzyme problem because food "stays with me" for many hours and am miserable when I eat a large meal. Thanks for all you share Dr. Cywes, I feel like I am putting more pieces of the puzzle together.

This is brilliant. It is exactly the answer I have been looking for. Carnivore/keto since early October. Love fasting but was told to eat fat every two to three hours, and absolutely no fasting. I eat 60g protein, 0-10g carbs (veg), the rest of calories animal fat. I have gained 25 pounds. Tonight I decided I’m going to start fasting again. I hate eating fat all day, I just don’t want it.

[@JYAN2852]

Hey doc there are few exceptions to prolong water fasting beyond 72hrs worth mentioning. It speeds up insulin sensitivity, lowers inflammation, and cancer. I am also not a fan of dry fasting either as we do require electrolytes for nerve signaling, muscle function, and blood pressure regulation among many ither reasons. But several days of dry fasting is fine for those who are use to doing it. With fat beta oxidation as well as gluco neogenesis the byproducts are water and carbon dioxide

[@robertcywes2966]

Agreed, but dehydration not good. We recommend exercising during fasting hence water and electrolytes

The drinking of beverages is prohibited from sunrise to sunset during Ramadan. It's not just food. I find that there are two aspects of this spiritual practice that are suboptimal as a dietary practice, there is no biological benefit to dry fasting versus a water fast that I am aware of, and eating two meals right before you go to sleep and again right before sunrise means that you are going to bed on a full stomach and you are going to be chronically sleep deprived. When I imagine doing this for a month in a hot desert climate it just looks like self torture to me.

[@ekondigg6751]

It usually happens when starting keto, you smell "fruity" from the acetone the body is producing. But later, when the body gets more fat adapted that tends to go away. I assume it comes back in Dr Cywes case because he was producing a higher amount of ketones than most, as his glucose was going into what would be considered the hypoglycaemic range.

[@dalialovesdoggies4361]

Dr. C....you have extras to burn off for energy. ..what happens if one does not have 😊extras????

[@Animeabe]

Perhaps I can get an answer. I don't understand why it's time based. He said 36 hours to get into a fast. Is that assuming an average amount of calories burned? On the weekend, I may burn 2500 calories just laying around. On work days, my fitbit says I'm burning 5000 calories. How does this affect fasting times and autophagy? Wouldn't a caloric defecit make more sense? Thanks.

[@jhillfineart]

Curious to know what the differences are between you and Dr. Fungs opinions are. His books were my first intro to keto and fasting.

[@nataliajimenez1870]

I think that Dr Cywes is similar to Dr Phinney who are very concerned with muscle loss in extended fasts. They both agree that up to 48 hr fasts are ok (as long as there's proper refeeding in between), but longer than that it can be dangerous except for very specialized situations like fasting during chemo treatments to maximize their efficacy. Dr Phinney is also concerned with a reduced metabolic rate for those that fast too often. I've done 3 days a week alternate day fasting and it has worked well. Sometimes I do the modified version that allows up to 500 calories a day in the "fasting" day

[@Meritumas]

I think all depends on context. Dr Fung talks usually about therapy for metabolically sick people. Once you regain your health it would be better to do 1-2x 36hr fasts per week instead of 5+ days periods without food.

[@jhillfineart]

@@nataliajimenez1870 thanks!

[@jhillfineart]

@@Meritumas makes sense!

[@jennie9]

Dr. Fung talks about longer extended fasts, like 5 days or more, but it's more when he's discussing fasting in theory and science. In practical application, the company he set up with Megan Ramos, called The Fasting Method, mainly recommends regular 36-48 hour fasts for therapeutic purposes. Some examples are three 36 or 42-hour fasts or two 48-hour fasts per week with 2-3 meals on eating days. They don't recommend really long fasts, although they do provide some info on them to keep people safe, like info on how to break those fasts to avoid things like refeeding syndrome.

I've done dirty keto for a few years and carnivore for 5 months and I still can't get into ketosis. I regularly fast 16 - 24 hours for a minimum of 9 months and still no ketones, no weight loss. I've gained and lost the same 6 pounds over and over. I need to know how to get into ketosis. I have a blood monitor to see my ketone levels. It is .2 or .3 which is not in ketosis. Maybe I should take ketones. Help please.

Hi Doc. From your practical experience do women feel better on carnivore diet during menopause?

[@sandrasatterfield4432]

I sure do!!!!!!!

Would you share the brand of the CGM you’re using?

[@corbanallard8419]

Skeletal muscle isn’t the only source of protein in the body, plus, doesn’t the body recycle or break down junk proteins before finding good protein to convert into glucose? HGH goes up on extended fasts (peaks around 72H, I believe), which helps preserve skeletal muscle. I’m not convinced extended fasts for obese people isn’t a good idea.

My first day on carnivore just completed my 72hr fasting I'm 400 pounds 😢

Check out Dr. Ken Berry You got this! You are worth it! Eat to live ....not live to eat

I did a 10 day water fast. No bother!!! But you MUST be fat adapted first!! Drink sugar free electrolytes if you have low blood pressure like me. It is great! I could have kept going but I was getting nervous so I ate. I immediately got diarrhoea but I think that was the shock of eating a full meal.

As Dr. Mindy Pelz explains, your intestinal stem cells are rebuild after a 24 hours fast. It is normal to get diarrhea afterwards. I get it too.

My herb tea is my bridge

Usually i do an 48 dry fast and i had only positive results

[@missblack8810]

He never answered the question is it safe to break a prolonged fast with meat??? I have the same question

[@sandrasatterfield4432]

I would not do meat to break a fast.....a few boiled eggs would do. You've given your digestive system a break....why shock it by giving it meat right off the bat.

The main problem with any discussion of prolonged fasting is that there does not appear to have been any clinical trials to prove any of the many theories out there on the effects on the body, metabolism, the brain, etc. Every pro-fasting doctor on KZbin has case studies and theories based on their understanding of endocrinology and metabolism, but none of them can back up their claims with published studies from peer-reviewed journals. What is needed is a randomized clinical trial (in fact, multiple trials) with a fasted group compared to a control (whatever that might be) group and a measurement of the effects of the prolonged fasting on different biomarkers. Perhaps it would included multiple groups fasting for different lengths of time or consuming different levels of calories from 0 to X. Absent hard data, all of these videos on fasting from all of these doctors are just anecdotal and theoretical, regardless of the qualifications of the presenter. Please don't make major decisions about your health based on a couple of KZbin videos with no study references or data to back them up. Then, please don't make health decisions even with the studies to back them up without consulting with a health and nutrition professional that understands the science and your own personal requirements.
