    Farmers basically eat twice a day, breakfast after morning chores and supper after evening chores. We never had lunch growing up, just didn't happen and we were thin.

      Yes. Never were breakfast people growing up. As a kid I'd have dinner at 6-7pm, go out to hunt early the next morning. Have nothing , not even water, maybe a few sips of dad's coffee to warm up. Get home , dress game, fish then dinner about 6 again. That's a 23ish hour dry fast a time or two a month. We were strong and active kids.

      Well, not all farmers. My mother’s family were farmers as were some of my father in-laws family. They ate breakfast, dinner and supper. Breakfast was a large meal after mornings first chores. It was very early. Dinner was a large meal about or shortly after noon. Supper was the evening meal with left overs from dinner and maybe something else added if need be. Generally it wasn’t quite as large as dinner. All these farmers were my grandparents generation. People born very late 1800s and before 1920. They didn’t really eat lunch foods.

    I heard a fitness guy named Charles Poliquin say something that made a lot of sense. He said "you have to earn your carbs." Basically the more physically demanding your life is the more carbs you can get away with eating. For most people's lifestyles today they'd be better off focusing on protein and healthy fats and keep carbs to a minimum except on days where they're way more active.

    Before I even was a quarter of the way through this interview, I immediately looked up whether or not Dr. Mattson was vegan. He is probably healthy, but he doesn’t look it to me. When I was on keto and lost all my weight, I had the same look. I was not eating enough meat. I gained some of the weight back, and now I am doing Carnivore. I have increased my meat and collagen intake, and I am hoping my face will not look quite so emaciated. It may just be a product of being 70 years old but I’m hoping I’ll have a little bit of fat on my face. Oh, well, it will be what it’ll be!

    Eating 3 meals a day has nothing to do with farming. When you are working hard, you may want a break but you don't want to eat because that makes it difficult to work afterwards. We just waited until supper when we could enjoy a good meal, relax, then sleep.

    I have believed for a long time now it is how frequently we eat that makes a huge difference with longevity. I think the activation of the processes to digest food takes a toll, especially when it occurs often and closer together, with less time for all the things that need to recover or happen between meals. Eating 'normally', we just never let the body recover between meals.

      When we eat the primary role of the body is to digest and all other bodily processes fall by the wayside. So the less digestion the more time the body has to function properly.

    Fasting just happened naturally for me when I started keto because I just wasn't hungry. I use to get the shakes if I didn't eat but that doesn't happen anymore at all. I fast 18-22hrs or so. I just eat when I get hungry. I feel so much better when I don't eat 2-3x a day and going carnivore makes me feel even better than keto did. I've learned that 99% of veggies don't agree with me. I have fibromyalgia, RA, chronic fatigue syndrome and Celiac disease. If I eat sugar, dairy, starch or carbs of any kind including veggies, I feel horrid and my body hurts. If I eat only meat, butter, bacon and eggs, I feel normal again!

      @TAS1965 Рік тому +4

      @Debbie Goad Yes, if I eat carbs, starchy foods, sugar, dairy and most veggies and spices, my symptoms come back. They make me feel horrid, my body hurts, and the veggies tear up my stomach and make me feel bad. I'm still sick but a lot better than I was. It takes time to heal the gut and get better. I moved to Carnivore at the end of March. I've tried reintroducing foods, but they still bother me. I'm hoping that eventually I can eat some veggies, I miss salads. The gut has everything to do with health, so healing it is important and takes time. We didn't get sick over night, it took yrs so getting better isn't going to happen over night.

    • @TAS1965

      @Debbie Goad People have to want to get better. They won't listen to you and do anything until they are sick and tired of being sick and tired or they have a serious health scare. I totally get it. I love food and I love to eat. I use to say I didn't eat to live, I lived to eat. I was addicted to carbs and sugar.
      I started keto because I was sick of being fat. I had gained 60lbs and I could no longer work. Keto made me feel better and I lost 27lbs. I just kept learning about it and how foods can cause health issues, including mine. I also take a few supplements. I was able to go back to work in Jan after 15yrs! Keep sharing testimonies and videos. When I share videos like Dr. Berry, I tell ppl to read the comments. There is always amazing testimonials there.

    Hi Dr Berry
    Every morning I have 2 cups of water with lemon
    Then give or take 1 or 2 hrs later I’ll have big fat coffee with MCT.
    That allows me to not eat while I’m physical at work reachin over 12,500 steps & then walk for an hour = 5.5kms & then head home to eat the first meal of the day so give or take between 3 n 4pm.
    I only eat meat, goat cheese, eggs, kafir.
    At the end of the day I slip on a cup of bone broth.
    Life is good on carnivore

    Dr. Barry asked him if there was any harm in the ketogenic diet. I have followed Mark Manson for years and he has always said that it is vitally important that we switch back and forth from the metabolic switch from burning fat and making ketones and switching back into it a glucose fed state. He says that the benefit is in the switching that the metabolic switch goes back and forth every day, so I am confused why he didn't bring this up today

    I fast once/wk for a 40 hr time period, from Wed night to Fri afternoon. I supplement when breaking the fast. Also exercise 3 days/wk with weights and 2-3 days walking for 1-1.5 hrs.
    Have been doing this for 7 weeks, along with cleaning up my diet (less carbs, no sugar, no processed foods).
    Have lost 23 lbs in seven weeks. Not necessarily doing any particular diet, yet at times i’ll eat keto meals.
    Ran across all of this after getting POTS symptoms post-recovery from long-Covid, as well as having fainting episodes. I went to a few doctors and even the ER when i thought i was having a heart attack.
    What i’ve learned is that i was metabolically broken, and that the current medical apparatus completely failed to asses my situation appropriately.
    I’m on the lookout now for a doctor outside the system who can help me with my diet, hormones and fasting advice. Most doctors nowadays are not equipped with the info req’d to help 93% of people in the U.S. with their metabolic health. I’m 49 and seriously thinking about how i can get help with diet/fasting/exercise as a holistic approach of healthcare rather than getting into the current system again.

My parents both smoked like a chimney and drank like a fish, mom died at 63 with cancer and tumours that she didn't know she had, and dad died at 74, in his living room chair. He was found a few days later by his buddy, and there was an open bottle of whiskey on the side table right beside him. He also had a number of health issues, many that he hid from us that we didn't know about until we cleaned out his house. I, on the other hand, Never got into smoking because of the disgust I had of it growing up with it always in my face, and I don't drink. I am healthy as a horse, on keto, and will live until I'm old and gray, dying peacefully in my sleep at 105 years old like my great grandmother 🥰

    Mark reminds me a little of Doc Brown in back to the future. Great info. One issues with the blue zones is healthy user bias. Higher carbs in those zones also preclude the eating of junk food and drive throughs. Even plant based will be healthier than standard American diet. The people eating meat in a drive through with industrial seed oils coating the fries and the milkshakes are equated to “meat eaters” There are no large modern communities of predominately carnivore or clean ketogentic to have a real comparison so of course blue zones will have longer life spans. Of course high fiber plant based will be better than industry lab creations with a side of death.

    I agree not eating for 16-18 hours a day is life extending . This might be the reason why some people can smoke and drink and lived till they’re 99. Looking at the older patients of mine over the years. I realize the ones that were smokers and lived over 85 basically had a black cup of coffee and a cigarette for breakfast and didn’t eat for hours. That might be the reason why day we’re lucky enough to die from heart, disease, or cancer. Definitely don’t think anybody should smoke one cigarette ever but I’m seeing a trend over my 40 year career. Also, centenarians will tell me that they naturally fasted 14 to 18 hours a day sometimes just having a cup of tea in the morning. Or eating breakfast at six lunch at 12 and then not eating at all until the next morning. Maybe the autophagy Eats up all the bad stuff and allows them to live longer. I do notice this guy does not agree with Dr. Berry on diet other than the inner minute fasting. I’m not a carnivore, but what one wants to do to improve is what is important if they can make it work . If you want to live to 75 carnivore but if you want to live to 100 no. I’m looking at this objectively. I don’t agree with the carnivore diet. I do agree with a lower carb diet using Whole Foods staying away from processed greens if any grains at all. Grains are polluted these days. Very sad.

    And immediately got online and went cold turkey keto. It works for sure but still had glucose spikes prob bc of almond flour, veg, etc carbs.
    Went to carnivore 2 months ago. It’s so simple, yummy and satisfying. Spending less money, less produce waste, less garbage, NO spikes at ALL, less time spent on keto and keto cheats. I rarely I’d ever need a cheat because I’m
    So satisfied.
