What is the Ketogenic Diet? (Basic Concepts Simply Discussed)

September 24, 2019

hey this is dr. berry in this video let’s discuss the ketogenic diet now you may have heard about this diet chances are you have word about the ketogenic way of eating is spreading like wildfire and for good reason actually for multiple good reasons and I wanted to make a video to talk to just the very basic beginner somebody who’s just heard about the ketogenic diet you may have heard some good things about it you may have heard some great things about it or you may have even heard some bad or dangerous or scary things about it and I wanted to make a video just for you so that I could talk about the basic concepts behind this diet and help you understand this better because it’s so important so let’s talk about the ketogenic diet now if you know someone who’s just thinking about starting keto or who is just started keto or you’re thinking about it please share this on your Facebook page if you know that you have beginners in your ketogenic or low-carb high-fat group please share this video to help them learn what this is because they need to know so let’s get into it the ketogenic way of eating what is it what’s it about what’s it do why is everyone so on fire for this way of eating so first and foremost the ketogenic way of eating is low carb that’s very important for the ketogenic diet to work there are essential fatty acids that you have to have if you don’t get them for a long enough period of time you will get sick you will suffer and you will die there are essential amino acids found in proteins that if you don’t get them for a long enough period of time you will get sick you’ll suffer and you’ll die eventually because you have to have certain fats you have to have certain proteins for your human body to function properly now what you may not know is is that there is no such thing as an essential carbohydrate there are no such thing as essential sugars no such thing as essential starches they don’t exist there is no such thing you could take a human being and lock them up and feed them only fat and protein for the rest of their life and they would do great they would thrive they would be vibrant and vigorous and happy because there’s no such thing is an essential carbohydrate so the ketogenic way of eating takes advantage of this because we know that carbohydrates can have negative effects in your body if you eat too many of them and so the ketogenic diet is a very low carbohydrate diet so it’s also a very high healthy fat diet and so in the ketogenic way of eating you’ll get to enjoy lots of healthy high fat foods and that’s because the fat does multiple things for you okay now there are bad fats that you should avoid at all costs fats such as canola oil corn oil soybean oil those are bad okay safflower oil any hydrogen hydrogenated oil you need to avoid because they’re very bad for you you need to avoid margarine I can’t believe it’s not butter Country Crock any fake oil substitute Crisco or any of the hydrogenated shortenings they’re not good for you they’re bad for you you need to stop eating them immediately and you’re gonna replace them with good healthy fats like butter like avocado oil like lard like olive oil all of these fats are actually good for you and you can enjoy them as much as you want on a ketogenic way of eating these fats do multiple good things in your body the next thing that you need to know about the ketogenic diet is that it’s about whole real foods the ketogenic diet is not about prepackaged weight watcher or Lean Cuisine frozen dinners that that you might call them pseudo dinners because there’s really no actual nutrition in them the ketogenic way of eating is not about any product there’s no product for you to buy that you need to do keto right you don’t have to buy keto shakes or PAP powders or bars you don’t have to buy Atkins anything you don’t have to buy a low carb high fat anything there are no products that someone who’s truly teaching you about the real ketogenic way of eating is ever going to recommend to you okay so if anybody’s trying to sell you exogenous ketones that’s not real keto if they’re trying to sell you bars shakes pills powders that’s not real keto the ketogenic way of eating is about eating real Whole Foods if you can Oh or if you can afford organic and grass-fed that’s great buy those if you can’t afford those yet that’s okay you can still keto okay you can still do keto on a budget there are many videos on my youtube channel here and on other people’s YouTube channels that explain to you how to do keto on a budget you can do keto for cheap if you need to right now we always want you to buy the best quality Whole Foods organic foods that you can afford but if you can’t afford those yet you can still keto the ketogenic diet is also the most ancestrally appropriate DNA appropriate diet that a human being can eat and I tell people this example if you could travel time travel back in time 50,000 years okay and you’re in the northern US you’re in the Canada you’re in Northern Europe you’re in anywhere in the northern or various southern latitudes what do you think that you and your ancestors would eat every day you would eat meat veg you would eat mostly meat in many months out of the year you would eat meat and vegetables of the year and maybe for one or two months out of the year you’d have some fruit or some berries to eat but on the whole the human DNA and and the human ancestry just knows what to do with the ketogenic diet because it’s very ancestrally appropriate human beings have been eating a ketogenic diet for millions of years this is not a fad diet this is not some new weird unheard-of thing humans have been eating this way since the beginning of time and even before so in that respect a lot of people like to call keto the latest fad diet and that’s kind of silly and short-sighted sophomoric even the ketogenic diet has been around forever and will be around forever what’s actually the fad diet is the diet that we’ve been told to eat for the last 50 years which is lots of whole grains lots of carbs eat low saturated fat and eat lots of pre processed products that’s the fad diet not keto the ketogenic diet is also very metabolically powerful now what do I mean by that the reason that we eat the low-carb of keto is so that we can control our blood sugar in our insulin it looks like the more research is done that high insulin levels pathologically chronically high insulin levels lead to almost all the chronic diseases that modern man suffers from it’s from high blood sugar it’s from high insulin that’s what causes so many of these chronic diseases that you and your friends suffer from today so that’s part of what keto does is it Hex your blood sugar and it hacks your insulin level and puts them back where they need to be and and I think that’s the reason for that is is because it’s the diet humans are supposed to eat the ketogenic way of eating also optimizes your leptin and your ghrelin hormones and these keep you from being hungry okay the other thing the ketogenic diet does that’s very therapeutic is that it helps you have ketones to burn your brain can burn ketones just as easily as it can burn glucose but if you’re eating a high carb low fat diet you don’t ever give your body the good fats that it needs to be in ketosis if you’re eating lots of vegetable oils which actually don’t have any vegetables in them then you’re you’re building your neurons and your brain and yours your cell membranes out of faulty fats then those sales are bound to fail eventually so the ketogenic diet is very metabolically powerful the next thing is I want you to know is that the ketogenic diet helps your body remember that it can burn fat as fuel so all the fat that you may have stored on your belly on your booty on your thighs other places what is that fat why is it there your body has stored that fat because you’ve eaten too many carbs for the last few years your body stores that okay and that stored energy that’s all fat is there’s nothing magical about it but if you’re eating carbs continuously your body doesn’t have any reason to burn that fat only when you bring the carbs down very hello and keep the fat hi do you remind your body oh yeah I can burn fat for fuel as just as easily as I can burn carbs your body will kick back into ketosis and it’ll start to burn the stored energy that’s on your booty and on your belly now the worst and most dangerous fad of all almost no other diet can get to you’ve probably seen people who go on calorie restricted diets like Weight Watchers flexitarian Hornish Jenny Craig and they’ll lose weight but they still have that belly that’s the most dangerous fad of all and the ketogenic diet is the diet that is the best at getting rid of the fat inside your belly inside your liver inside your pancreas that’s why I love the ketogenic diet so much is because it gets rid of the dangerous fat first not last another thing you need to know about the ketogenic diet is like I’ve said before it’s very therapeutic so many people with chronic inflammation with chronic immune diseases notice when they start the ketogenic way of eating their inflammation gets noticeably better their arthritis their their reflux or GERD their heartburn they’re Crohn’s they’re irritable bowel all of these inflammatory conditions just get better and go away many people notice that migraines get better and go away they notice that their ATD their PTSD their anxiety their depression all of these things it looks like are coming at least in part from inflammation the chemical imbalance theory that you may have been taught by your doctor as a reason that you should take this pill once a day for your anxiety or depression turns out there’s not a shred of research that proves that there’s any chemical imbalance at all more than likely what’s going on is that your brain is chronically inflamed from the crap food that you’ve been eating and once you start feeding your human body the human diet that it loves the best which is the keto diet all that inflammation will go away many immune diseases although there is a genetic component to these are kicked off and put into high gear because of the inflammatory nature of our modern Western diet and once you get that diet out of your and replace it with an ancestral appropriate diet like the ketogenic diet those immune systems are those immune diseases that you thought you were stuck with for life your your Crohn’s your MS your all of these others they just calm down and they quiet down and all of a sudden you’re not having flares anymore all of a sudden when you do have a flare it’s a very minor flare of psoriasis or gout or some of these other conditions that are inflammatory and immune in nature another thing that the ketogenic diet that I personally love about it is that it’s delicious you get to eat thousands upon thousands of delicious foods that that have grown on the earth or that have run around on the earth it’s a completely natural diet now if you enjoyed this video and it helped you understand more about the ketogenic way of

    It's nice to have a "Doctor" on YouTube who is an actual doctor and not a chiropractor. Most of the "Dr So and So" on YouTube are chiropractors. One of them said you could resolve Diabetes overnight by getting rid of carbs. (Eric Berg) My Type 2 Diabetes husband has been on Keto for two months and he gets maybe 10 carbs a day. And his diabetes is not resolved. We believe it will improve greatly as the months go on but it's not an overnight thing. Not at all.

    Hi Dr Berry. I know people who have had success with KETO, so I decided to go KETO, too. I've been eating strictly clean KETO for 4 days, but I have GAINED 5 pounds! HELP! I'm going to go through your 101 series, and am already familiar with many of the concepts of which you've spoken. I'm 80 lbs over weight, age 72, have survived hormone positive breast cancer, and carry most of my weight in my belly. What might I be doing wrong? I do have an auto immune disease of the liver, so it's especially important to reduce inflammation. I have sugar addiction, however I've completely gone off sugars and flour, breads, etc. I've never been one for soda, drink mostly filtered water, and eat whole foods. Why am I gaining weight instead of losing???

I do however want to make sure she starts the right way. She was diagnosed with CHF (congestive heart failure) she also suffers from depression and anxiety. What’s the best way to help her get started?

  • Reply estimatedeyes August 12, 2019 at 4:55 pm

    Hi Dr. Berry! I find your videos very informative and SOOTHING! Thanks for making them! Listen, I'm just starting out on keto, and I did something before not really researching…I bought keto pills! In truth, I live on a farm and I eat a pretty ketogenic diet anyway, but my biggest issue with this diet, as with many others, is cutting out the sugars and the carbs. I've got diabetes in my family, and I'm at the age now that I remember my father was at when his signs of diabetes turned into taking insulin pills and I'm afraid of going down that same road. He never changed his diet, only took medications to control his blood sugar levels, and now at age 76 he is on dialysis. For the past week I've cut all sugar and carbs from my diet, and find this change not that big of a deal because since eating much more fat, I'm not hungry all the time! But back to these pills, tell me what to do…should I still take them? Will they benefit me and help me lose weight quicker, or are they just beneficial when you like eat something sugary or carb filled? I'll wait to hear from you. Thanks a bunch!

    Dr. Ken. I'm new to your page and Keto. Been learning for about 6 months now, it took me a bit to really learn and understand. I just started experiencing hair shedding which makes me nervous. I try to get my protein daily but struggle. I really never ate too much when I was non Keto, always struggling with daily food intake. I started this journey mainly for infertility as my fertility Dr. Recommends Keto and recommends Maria Emmerich. Any tips or suggestions for these two issues? Thank you!

    Just completed first week on keto. Lost a few pounds in "moderate" ketosis, but hit the same wall as in prior attempts: intestinal spasms (feels like jumping beans in the colon) and heart skipping (even though I take 200 mgs of flecainide daily for arrhythmia). I thought after a week of no grains or sugars, my abdominal pain (both sides) might improve at least a little bit. Taking these supplements: Vit D-3, magnesium glycinate and coQ10. Wasn't hungry first few days; famished yesterday. Any idea what I might be doing wrong? Appreciating your videos. Thanks.

    Dr. Good afternoon, I would like you to help me with something. I have more than a month on Keto diet, but sometimes, I will not lie, I have "falls" with bread or candy, it is not always, of course, but I have noticed that I have a deep pain in the stomach. Is this dangerous for the diet?

    I appreciate your response, since here in my country, there is no doctor to tell me something, since if I mention the keto diet they tell me to stop it right away and that it is bad. and the truth is that I think it's because they don't know her or have researched her well, they just think that because she is fat she is already bad. Thank you so much.

    Ok! I have been trying keto now for about 4 months. In order to tolerate this way of eating, I had to add berries and some watermelon. If I don't, I feel too weak and cannot function at work. I haven't had any flour, grains of any kind, starches or sugar but I am eating too many vegie/fruit carbs and calories from meat, cheese, peanut butter, avocado, almonds, cream, etc. (I don't like bacon so I don't eat it). My cholesterol spiked a bit too which is sort of scary. I have AC vinegar every morning. My clothes do fit a little more loosely, however my weight has not changed. Unfortunately I haven't found any diet alternatives. Other diets I have tried lead to this same weakness and I end up not sticking to them. So far I am trying to stick to this one as much as I can.
