What The Keto Diet Actually Does To Your Body | The Human Body


Narrator: Step aside, Atkins, there’s a new fat diet in town. The ketogenic diet or keto for short. Celebrities like Halle
Berry, Kourtney Kardashian, and Vanessa Hudgens all swear by it. And if losing weight is
your goal, keto works. It’s proven to help you shed pounds fast. But there’s more to this
diet than meets the eye. Keto basically replaces carbs with fat. A typical keto diet looks like this. 70% fat, 25% protein,
and 5% carbohydrates. It’s a drastic change from the diet that the USDA recommends
for most Americans, which is less than 30%
fat, 20 to 35% protein, and at least 50% carbs. And it’s a significant change for your body’s metabolism too. Usually, when you eat carbs
like a starchy potato, enzymes in your mouth,
stomach and small intestines break them down into a form of
sugar energy called glucose, which your brain and body use for fuel. So when you first skip out on carbs, the first couple days you might experience some strong sugar cravings. That’s because your
body is switching gears, from converting carbohydrates to the only energy it has left: fat. Once you’re burning fat regularly, you’ll see those pounds
start to melt away. Depending on your weight, you might lose up to 3.5
pounds within that first week. As you burn more fat, levels of insulin, the fat-storing hormone,
will drop significantly. This triggers your kidneys to release large amounts
of sodium into the blood which can actually lead to a common side effect
known as the keto flu. Many keto dieters report
symptoms like nausea, headaches, dizziness, muscle
cramps, and low energy levels. But most of these symptoms will only occur within the first couple
weeks of starting the diet. After the first month, the
scales will look better but some of that lost
weight isn’t actually fat, it’s just water. Because some of the carbs you metabolized include glycogen which retains water and therefore helps keep you hydrated. As a result, you’re
likely to pee more often which will lower your
sodium levels even more leading to dehydration,
constipation or diarrhea, and bad breath. Once you’re a couple months in, you might hit the notorious keto plateau. It’s a common term in the keto community. It refers to when people
find it progressively harder to continue to lose more weight. One study, for example,
found that overweight people lost an average of 15
pounds in the first month. Another 11 pounds over
the next two months, but after that, they saw
no change in body weight despite sticking to the keto diet. At this point, many people
will just quit keto. That’s why researchers
often find it’s so hard to study the long term
effects of the diet. But, as it turns out, there’s one group that typically sticks to
keto for a really long time. It’s unclear why, but keto is proven to reduce the symptoms of epilepsy and studies show that epileptic children who stay on a very restricted
keto diet for several years can suffer from kidney stones, high cholesterol, and bone fractures. But a typical keto diet
won’t be nearly as strict. And if you wanna try keto, you should talk to your doctor first. In the meantime, go
ahead and get that bread, and remember, the best
diet is a balanced one of fat, protein, and yes, even carbs.

    im on a caloric deficit diet, im still eating hight fiber carbs and avoid as much fat as possible, im losing more weight that i've ever did in a "ketastasis" state. I'm starting to think keto is just a marketing strategy from the dairy compannies. Carbs arent evil, if you eat green high fiber carbs you dont put on weight. The problem are the high processed carbs like, wheat white flour, white rice, and white sugar. You have to remember that there are bad things from a keto diet, like high colestherol, trans-fats and acne. Stop being stupid and eat your greens, avoid bread.

    Lol ur so full of $hit. Not 100% fact at all. Ur just like parents out there do as I say not as I do. Let's just listen to the fda cause they help us.

People r saving there lives by doing the keto diet so mmmmm nicely u n the fda can stfu.

    What a misleading video. Eating mostly carbs in my life has made me overweight. Doing keto even not strict keto helped me lose 70 pounds! My blood pressure is finally normal and my love handles are falling off. I thought id never lose weight. Eating more vegetables and fish is a good thing.

  4. Michael Enright

    Best keto diet is healthy keto. You eat 7 to 10 servings vegatables along with moderate protein and fat. Make sure to get enough salt and a good electrolyte supplements!!. Mix in intermittent fasting and you will keep losing wait till you get to your ideal weight and get those washboard abs.

  5. Amy GÜRKAN

    Its 5 to 10 percent carb, like vegetables. 25 percent non lean protein like beef, and 65 to 80 percent fat. That is healthy fat. Like avocado, tuna, salmon, nuts etc. Its a better way to eat and exercise and your body feel tons of better. You can have sugar but use xylitol. It's all about choosing the healthy way to balance out what the body needs. If you do it right and stick to it.

  6. Maja Kozłowska

    True! I was believing keto diet is the best in the world, but fortunately I have watched some videos about side effects and now I’m happy I’ve never been on this diet

  7. fredhair

    Poorly researched, no sources and the advice to eat bread is probably worse advice than try a ketogenic diet. You're much more likely to have a problem with wheat especially fortified bread high in gluten. Gliadin is not food for humans we can't digest it and it is very dangerous and damaging for some people. I don't adhere to a keto diet but I know it's not a bad diet if you're fat and unhealthy. I'm already thin and quite healthy and consume small amounts of healthy carbs from oats, potatoes, rice, fruit and veg so haven't much need for the main benefits of keto

  8. Zuko Here

    My friend and I started in the low 300's. He followed the food pyramid, I follow keto and intermittent fasting. I'm 238 and he's 360 with diabetes. I can only say it's worked for me.

  9. Mobius Trip

    Hey vegans, you know the way to a man's heart is through his stomach right? Except if he's a vegan, in which case it's through his vagina.

  10. IamMe

    But … you don't eat a keto diet for the weight loss. Who would be so foolish? just eat less.
    You eat keto for the more consistent, mental, emotional and physical state …

  11. Jezer Sauceda

    Do whatever the diet you want being overweight and you'll always reach a plateau. And of course you can be healthy eating a balanced diet, but it's hard while eating carbs for they make you want to eat more carbs!! And being honest, most of modified HARMFUL fats are always accompanied by refined carbohydrates. So, if you take all carbohydrates out of the equation, you'll be forced cooking and eating more naturally

  12. Marnie Knox

    How are the USDA recommendations working for most people? Look around you, not so good. Ya, talk to your Dr. …about how many hours of medical school cover nutrition. Next to nothing!

  13. Bismark Bizmark

    There's some actual science in this video, but it's riddled with onerous cliches. For example, it seriously suggests (as an unquestioned given) i should consult a doctor, who is as capable of mistaken or uninformed advice as anyone, for my dietary decisions, rather than base these decisions on my own research. The snidy subtext at the beginning also is in bad taste. For the strongest argument, stick to the science.

  14. N&A Galletti

    Hahaha. I love KETO. It's a lifestyle!! It's about getting healthy and feeling good. I'm a type 1 diabetic and I'm so happy now that I don't need to inject insulin 5 times a day. I'm 21yrs old. And I wasn't overweight. But I stick to keto because I can now feel good.

  15. Joe M

    WRONG! The Keto diet is approx 70% vegetables and 30% fat and protein. The emphasis on veggies is what differentiates it from the Atkins diet.

  16. Anthony Ortiz

    This video is just as good as the garbage I took outside earlier! USDA was mentioned, and that discredited this video, and it’s “science” entirely. Yes “dirty keto” can be bad for you, you can’t have dairy and unhealthy fats all the time just because it keeps you in ketosis, but there’s a proper way to do it. People used to incorporate much more healthy fats in their diets until vegetable oils appeared we were told that saturated fats were bad and vegetable oils were a healthier alternative, and heart disease sky rocketed! Fun fact, McDonald’s replaced beef tallow with a combination of partially hydrogenated vegetable oil and a chemical flavoring system… we all know how good McDonald’s is for you! The fast food industry makes lots and lots and lots of money, and of course good ol big brother gets its cut. Just like the pharmaceutical companies, I stopped taking meds, take my vitamins, and voila I rarely get sick and when I do I get better in 1-2 days WITHOUT MEDS, I won’t get into that though. My point, keto has been proven scientifically, and by tons of testimonies to be a great healthy eating lifestyle.

  17. David Coomber

    So if you start a presentation in the negative the outcome will be the negative. 45% of the US/world population follow a (balanced) diet and are diabetic or pre diabetes

  18. Justin Tremblay

    You lying prick you know that the kids on these studies went into ketosis by chugging seed oil wich YOU should know is extremely bad for your health.

  19. NeewollaH *

    This video was brought to you by Jillian Michaels! I’m in my 4th month of keto 18/6 intermittent fasting and I’m in love with it. This video is super mis leading. I was at 300lbs now I’m at 260lbs. First two months are a struggle but once you rid your body of all that toxic toxic Sugar and carbs then boom the magic really happens.

  20. Mr J

    Another laughable video, missing important information and generally misleading people. It does make me laugh that people have to write the word, 'science' everywhere, to try to add gravity to what they come out with. The USDA recommendations for what a balanced diet is, is outdated. They think a one-size fits all approach is actually an intelligent way to go. The idea of a balanced diet makes it sound we have to eat a little of everything. This just isnt true. Since cutting grains, potato, rice out from my diet and doing intermittent fasting, i no longer experience low blood sugar after exercise, or when i haven't eaten or a longer period than usual. My inflammatory conditions (gout) has disappeared. I don't feel the need to sleep after lunch. I feel much, much better.
    Check out Dr. Berg. He's very skilled at transmitting correct information. Anything with 'science' or, 'experts' slapped on the title is usually coming from mainstream media, and is incorrect and misleading.

  21. Len

    Anybody doing Keto knows you don’t worry about the scale because you are burning fat at the same time putting on muscle, there are a ton of DOCTORS who can walk you through it!

  22. Katherine

    I think if you want to lose weight and want to follow the keto diet is not a bad idea at all. But you do need other nutrients in your body… Keto is good also for patients that have to follow a very restricted diet, like patients with ckd.

  23. Lidia Cantu

    The USDA has been pushing grains on us for decades. Who the hell came up with the food pyramid? Grains are making us fat and sick. Stop buying your kids packaged foods full of wheat and sugar!

  24. jrg

    Pretty sure this guy is an idiot.
    I have epilepsy and did a major carb cut to control seizures. I didn't go as extreme as the keto classification. I played with low carb variations. Sugar, potatoes, fruit didn't do anything. The main thing I took out was bread. Added bread back and started to have problems. Stress and bread were my big triggers. I didn't have the "keto flu." I did have the energy drop while my body adapted to the diet change over a week or so then I was back to 100%.
    The reason a low carb diet controls seizures is the body doesn't have an active energy source on hand to have a seizure. A comparison I like is a striker for a acetylene torch. Strike it in the middle of the air and it just sparks. Empty that acetylene tank in the room and hit the striker again and you'll get a whole different reaction because now there an energy source on hand.
    I try to stick with an intermittent fasting routine-no breakfast, big lunch, small dinner. Anyone who says a specific diet and eating schedule works the best for everyone is an idiot. Different things work different ways for different people. The body eventually adapts to whatever routine you put it in.
    I will say I believe the gov pushing grains and such is a political agenda. Look at the degree of processing you have to do to even put wheat into a state where the body can use it. Eat a handful of unprocessed wheat grains and they'll pass the GI tract with zero break down. On top of that as soon gov started pushing low fat routines and towards high carb type diets obesity rates skyrocketed since.

  25. CJS929

    No, a "balanced diet" is not the best … you just think it is because it sounds good, it sounds so reasonable. Humans don't need carbs to survive.

  26. MobyDickHead

    I lost 65 lbs in 5 months with keto and exercise. My opinion if you are fat and fed up with it you should try keto and not give up on it (I watched thomas delauer, gravity transformation and ket connect on you tube for science info, and tips to keep me from making common mistakes) and. I've tried several diets before keto and they all sucked and made me feel like crap.

  27. Rodolfo Tenorio

    It's not keto flu, it's carb withdrawal. Drink water with salt and lemon juice. I have been eating less than 30 grams of carbs for nearly 15 years, best health ever. Total bs to ask your doctor, they (most of them) have no clue about nutrition, they mostly know how to prescribe pills as indicated by their pharma rep. Our food pyramid is totally corrupt and paid for by big agro and pharma money. Good try my friend, go educate yourself.

  28. Eliana Selzer

    The ketogenic diet is not a fad. It was designed in the 1920s as a way of treating epilepsy in adolescents. I love it when someone who has no idea what they’re talking about decides to make a video.

  29. Chris Pirillo Is Eboola

    Again with the "balanced diet" shit. Hasnt the US been speaking this same shit for decades? This is why obesity is a problem in America

  30. Susan M

    Here we have yet ANOTHER victim who's been brainwashed by the USDA & BIG food who upholds all of their lies and spreads them amongst society
    🤣🤣🤣🤣

    sorry won't be responding to all the haterz who are slowly and unknowingly poisoning themselves with GMOs, FAKE FATS (AS IN CRISCO CANOLA VEGETABLE OIL: DO YOUR RESEARCH PEOPLE IT WAS NOT MADE FOR HUMAN CONSUMPTION IT WAS ORIGINALLY MADE TO RUN MACHINERY AND NOW YOU INGEST IT ON A DAILY BASIS) who are on the standard American diet… FYI this video is presented on one person's unknowledgeable opinion of Keto.
    Dr. Eric Berg & Healthy KETO knowledge 💚 get ya some!

  31. MrPanther826

    Love the cartoon animation, the mumbling sounds… Even heard one of them say: Wanna get bread? Cracked me up! 🤣🤣. Aside from that, very informative.

  32. Graham Dawes

    I smell a big business sponsor behind this, trying to stop the world finding out how to stop the decimation of the population with obesity and diabetes heart disease and all the other constructs of the fast food and factory foods from the corporations.

  33. Alison Rennie

    I'm celiac. That is why I've been eating keto. The best way to avoid keto flu is to add salt to your water. It balances the procsss of ketogenesis. You also feel less hungry & have a little more energy. Much more to it than that though

  34. jeff hunter

    This video is clearly designed to discourage people that will NOT do real research about Keto. I would call this protection propaganda….Why mention some of the Keto negatives and not discuss the simple things to prevent them….unless you have an adgenda….to discourage people from Keto. Either way it is a very poor delivery of the facts….if you are being honest.

  35. Jams Saint

    people should stop overeating and blaming it on a high carb diet and give you're body 14 hours minimum to process the carbs you have eaten during the day i recommend eating from 9am to 7pm this way shou make you energized and satisfied.

  36. Rubester 1219

    Just make sure you are aware of keto flu and the things to get rid of it. As far as plateaus go thats part of life , does not mean you need to quit keto , just that you may need to do things like change your marcos , carb up or find what works for you. Most of the time would say consult a doctor , but with Keto would not. Keto might work for you and dr might just be anti Keto. That being said Keto is also not for everyone , nothing is. So would say if Keto works great , if something else is better for you , also great. Play around with things and find what works best for you! Also forgot maybe people plateauing need to change work out routine to loose again , may not always be diet.

  37. Wasted Sniperr

    WTF? Where is the Study that reduced cancer cells when she was on keto diet? Why is there hasn't been any bad reports of this diet, besides this RETARD channel. And there are way more evidences of benefits then this guy is describing.
    Are you just searching for what's bad about this diet then what is good. Did you ask your Dog to do this research for you?

  38. Misssfortune

    This is so stupid lol literally EVERY diet the first weight you lose is water weight. And even a "balanced" diet can also hit a plateau after a month. I guess that means no one should ever try to lose weight because any diet can have those side effects.

  39. Nasim Wehbe

    Wow!!! So much bs in this video. I've been keto since 11/2018. I am type 2 "diabetic".. Let's begin.. I've gone from 250 pounds now down to 195. From a size 44 waist to a size 36 waist and even 36 is starting to fit me loose. I was on 1000mg of Metformin twice a day. I was on the verge of being put on insulin by my endocrinologist. My A1C went from 12.2 down to 5.9 last time I checked on 6/2019. At 5.6 or less I will no longer have diabetes or as my doctor likes to put it "your diabetes will be in remission"… I have lots of energy, my sex drive is through the roof and I'm 44yrs old, yup I had E.D. due to the high blood sugar condition, well no more problems in that dept. My blood sugar was constantly in the 300's and now it is between 90 and 120. Yup my endocrinologist took me completely off the Metformin. Still have 3 bottles that I got refilled in January that I haven't touched. Finally I have gained lean muscle and my testosterone levels have gone up.

    Now on this video. The Standard American Diet is what has this country with an overweight and diabetic epidemic. Keto is not 5% carbs. It all depends on the person. In my case I kept my carbs at less than 20 grams a day, plus intermittent fasting. Now I have 50 grams or less a day. Sugar and processed carbs like bread, pancakes etc., are extremely dangerous to the body in the long run. I still get my carbs from vegetables that are also high in fiber.

    I will end it here because I feel myself about to go on a rant about the garbage that's been peddled to us by the government known as the Standard American Diet. Good day everyone.

  40. O Ttofos

    ''Balanced diet''. No dude, there are good things and bad things for humans if something is bad why would you need to eat it at all.
    We evolved on animal foods, we dont need carbs to be healthy.

  41. gilmaro84

    Better educate yourself before you post something. You just misled people with your poor nutritional and health knowledge. I think you need to watch Dr. Berg videos mate. Then review your clip again.

  42. Frankie Fernandez

    The introduction was wrong right out the gate. Keto is not the latest fad diet. Its humans returning to what the human body did for almost 2 million years, eat meat and vegetables and fasting.I lost 70 pounds of "water" doing this so called keto fad…ha ha ha. Of course your cholesterol will rise…your good cholesterol (HDL) . The increase in broken bones in children is from doing more activities outside after losing all that disgusting fat. Meat, proteins, and dairy actually makes your bones much stronger than a sugary carb diet…but they twisted the data some how.
