I agree that everyone should find the eating lifestyle that works best for them. On my part, keto reversed my high blood sugar & associated side effects that are now none existent. I also find it funny that many say there’s little research around Keto or Paleo type of diet yet before the discovery of grain & sugar out diets were pretty much meat, nuts, greens & depending on availability fruit. I come from East Africa & both my grandfather & great grand father only ate organic meat & vegetables….never touched carbohydrates, they both lived beyond 100 years …..This is the norm in most African families….. cancer, HBP & Diabetes seem to have surfaced with the introduction of sugar & refined carbs in our diets ……


Additionally, they remarked that “concerns about adverse metabolic effects of the Atkins diet were not substantiated within the 12-month study period.” [16] They acknowledged that more research needs to be done on the long-term effects on cardiovascular and metabolic health especially on men. However, their study supports the idea that a low-carbohydrate diet can help you lower body mass and body fat better than higher-carbohydrate alternatives.

The ketogenic diet — a high-fat and very low-carb eating plan — can be tough to start. After all, it’s likely a radical departure from the way you’re eating now (a typical standard American diet is high in carbohydrates and processed foods). But many people are trying the keto diet, which puts your body in a state of ketosis. That's what happens when your body’s carb-burning switch flips to a fat-burning one, a change that can cause weight loss and has even been credited with controlling diabetes. (1)
If you need to eat more or fewer calories per day, you can adjust accordingly by simply taking out or adding a bit more of the ingredients already included in a recipe. For example, adding/removing a tablespoon of olive oil or butter will add/remove about 100 calories. If you like or dislike certain recipes, feel free to shift things around. Make sure to keep an eye on the calories so you’re still falling within an acceptable range of your daily goal.

Hi Ben…first, I have learned so much from you, thank you! I’m interested in using exogenous ketone supplements and I have a question for you. I just read the transcript of an interview Dave Asprey did with Dr. Richard Veech (episode 299). He advises against them, and says they can even be harmful. I was disappointed to read this, and wanted to ask you about it, since I respect your opinion greatly….thank you.
So I slowly began cutting back on the amount of fat I was eating and adding in more carbohydrates. Foods I had missed so much like yams, potatoes, rice, fruit, whole wheat bread became part of my every day eating. I started eating out again. I started enjoying pizza and cake with my family again. I stopped tracking my macros. I gained more energy. My bloating went away. But most importantly, I started loving myself again.
Lower HbA1c: HbA1c is an abbreviation for ‘glycosylated hemoglobin.’ Hemoglobin is a protein inside red blood cells, this means it is always exposed to the substances that circulate in the blood (i.e glucose). When glucose levels are high, glucose can bind to hemoglobin (i.e it becomes glycoyslated). As red blood cells survive inside the body for 100-120 days, the amount of glyosylated hemoglobin is a good indicator of long term glucose control. The healthy limit for HbA1C is below 5.7% (Source: WebMD). 
Shifting your metabolism and achieving ketosis may speed up weight loss and result in other health benefits, like more energy and a lower blood pressure. But while ketosis is a preferred nutritional state for some people, it isn’t recommended for everyone — and it’s not a good long-term eating approach due to its restrictive nature, which may lead to potentially dangerous nutritional deficiencies.
Thank you for this article as it cleared up a bunch of stuff for me. I started trying to get into ketosis back in August and lost 20lbs in about 6 weeks. Then it all stopped but had another 20lbs I wanted to loose. I had a hard time staying in ketosis and gave up about a week ago with the holidays approaching. Anyways I glazed over all the technical and science facts as it makes my head spin and might of missed it but my only question is what is the food portion of the diet like? The drinks are the easy part, do you have a diet plan that is good for someone that hits the gym hard 4-5 days a week for and hour and half. 45 min weights and 30-45 min cardio? It’s what I struggle with most the food and what attracted me to a ketogenic diet in the first place is eating 1 or 2 meals a day and being satisfied.
Interesting article and I applaud you challenging any way of eating as so many of us are like sheep these days. However, for me, it’s really all about sugar. For example, the significant results of lowering sugar intake on type two diabetics should not be ignored. Look up Dr David Unwin’s success in the UK where many of his patients are in remission and, off their medication. I started a low sugar way of eating (diet is not a good word for anyone) Two years ago. I lost 20 kgs and have kept it off. I’ve looked at the science, I’ve looked at the manipulative history and current strategies of food manufacturers, but moreover, I look at my own results. Like you, I want my own ‘truth.’ We need to take individual responsibility in all areas of our lives to do that, instead of jumping on the next wagon of craze.

Ketosis is deliberately induced by use of a ketogenic diet as a medical intervention in cases of intractable epilepsy.[12] Other uses of low-carbohydrate diets remain controversial.[14][15] Carbohydrate deprivation to the point of ketosis has been argued to have both negative[16] and positive effects on health.[17][18] Ketosis can also be induced following periods of fasting (starvation),[19] and after consumption of ketogenic fats (such as medium chain triglycerides[citation needed]) or exogenous ketones.[20]


But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it's easy to go overboard on carbohydrates—but if you're loading up on fat, it may help curb cravings since it keeps you satisfied.
Fairly recently, the diet was introduced as a weight-loss diet by an Italian professor of surgery, Dr. Gianfranco Cappello of Sapienza University in Rome. In his 2012 study, about 19,000 dieters received a high-fat liquid diet via a feeding tube inserted down the nose. The study showed an average weight loss of more than 20 pounds in participants, most of whom kept it off for at least a year. The researchers reported a few minor side effects, like fatigue.
At the same time, you need to remember to increase the amount of fat that you eat. Also, it doesn’t mean a complete ban on carbs. You just need to reduce the amount that you eat to 15g or less per day. On average, we tend to eat around a third to a half more than that on a daily basis. Reducing carbs won’t be easy for some, which is why having delicious recipes to try first is the way to go.
Introducing @lowcarbjourney_jf: Hi there, my name is Jordynn, I have lost just over 60lbs using keto diet, started in early November 😊 getting married in 2019, and looking to be my best self! My goal is to lose 100-110lbs total. . . . #myketotransformation #fitspiration #weightloss #weightlossjourney #ketofam #weightlossmotivation #transformation #fitfam #weightlosstransformation #extremeweightloss #fitness #instafit #inspiration #motivation #fitnessmotivation #beforeandafter #diet #exercise #trainandtransform #beforeandafterweightloss #biggestloser #keto #lowcarb #lchf #ketotransformations

But while carbohydrates can help you have a better workout, go faster, or go longer, this only applies to acute, in-the-moment performance. Once you take a look (which you’re about to do) at the long-term effects of chronic high blood sugar levels, things change drastically. If the damage that you’re above to discover is worth it to you, then you are either mildly masochistic or you value performance much more than health.
I love your site but your note about Diabetic Ketoacidosis is completely wrong. DKA is not something that happens because your body produces too many ketones. It is something that happens when your body produces too many ketones, and you don’t have any insulin in your system. As long as a Type 1 Diabetic takes insulin they will NOT go into DKA. Especially since DKA requires high ketones, high sugars, and low insulin.
Apparently, Dominic’s research seems to be suggesting the fact that diet-induced ketosis from a high-fat, low-carb intake, especially when combined with the use of nutrition supplements such as powdered ketones or MCT oil, can vastly reduce the need for the brain to use oxygen to burn glucose. This is because the brain can use up to around 75% of its fuel from ketones. So a ketone-fed or a fat-adapted brain can be better equipped to withstand low oxygen availability and potentially support longer breath-hold times. Dominic’s research also shows that in the presence of ketosis, the brain and body are able to resist the potential cell damage of long periods of time with low oxygen, also known as “hypoperfusion”.
In addition, most studies that compare carbohydrate utilization with fat utilization fail to take into account the fact that full “fat adaptation” that allows you to gain all the benefits of using fat as a fuel actually takes time – often more than four weeks – and up to a couple years. But since most studies that compare fat and carbohydrate burning are short-term, you rarely see the benefits of this kind of fat adaptation actually fleshed out in research. Instead, the average research participant begins the study in a non-fat adapted state, gets either a high fat or high carb diet, then launches into exercise. But in an ideal study, that person would have followed either a high-fat or high-carb diet for many months before getting their fat burning capability investigated.
It’s Best for People Who ... have a tough time sticking to keto. “It can be helpful if someone wants to take a break and have carbs,” says Koche. That may not be easy for everyone. Kizer worries this approach may promote carb binging. You may have heard keto cycling recommended for athletes, who use the extra carbohydrates to fuel their workouts or competitions. But no existing published science backs this up, though studies, including an April 2018 study published in The Journal of Sports Medicine and Physical Fitness, have shown that the keto diet does hinder exercise performance.
I work with a naturopath to help heal my issues. She uses a ZYTO Elite to figure out the bodies frequences, food issues, and viruses. I was then told I had Candida in my tissue, leaky gut, liver congestions, etc. I was fairly sick. Been walking this road since October. She read me my food sensitivities and what my gut couldn’t tolerate. I was on a candida diet for 4 months, which is zero carb. Yet, she told me NEVER to be in ketosis. Impossible task. So, I lost 30lbs effortlessly on that. I’ve been noticing I went from muscle tone to NONE. Like, even if I flex my arm, you see no muscle. I was also very week and not able to exercise on keto. This is normal, I read. In March, I abruptly stopped losing weight, gained inches galore, and nothing had really changed, diet wise. I put on 10lbs. I re-scanned a few weeks ago and she was concerned that being in keto affected me. I came across your article and what HIT ME was that just 3 weeks ago she put me on potassium, magnesium, celtic sea salt, and some other herbs. But, all the ones you mentioned here. She stressed, again, please never go into ketosis. I can only tolerate sweet potatoes and yams now that i’m healing my gut, but so far i’m still not losing. I’m maintaining. BUT, i’m able to exercise now, so that is good. I think you are SPOT ON, from my own life experience with it, and thank you for sharing even though you’ll likely be torn to pieces.

Day 5: As fate would have it, 3 p.m. rolls around and we get a message that there are cookies in the conference room. I have been snacking on keto-approved foods like Granny Smith apples (the tart green apple has way less sugar than, say, a red Gala), and full-fat cottage cheese with blueberries (where have you been all my life, snack?) with no real trouble with cravings. But just knowing there are cookies that I can't eat makes me feel a little cheated.  (Though These Low-Carb Keto Desserts Help With That.)
Here’s encouragement…it’s not all about weight in the beginning. As you ween off of sugar (which is really poison to your body), your body has to start getting rebooted. I had a solid week or more of serious detox. I knew that getting the poison out of my body was going to be significant, and it was. Don’t be discouraged. It’s well worth it to truly rid your gut and body of cancer-causing poison, not to mention your ability to fight disease. The acid level will change. Your arthritis (joints) will improve. Stick with it and don’t give up. Your family is worth it!
While you’re focusing on fat, protein, and carbs, you should also make sure you’re getting adequate fiber. “People often assume that they should only eat things like meat and butter on the ketogenic diet,” says Farshad Fani Marvasti, MD, an associate professor and director of Public Health, Prevention, and Health Promotion at the University of Arizona College of Medicine in Phoenix. “You should make sure you are eating enough vegetables because you need the fiber.”
modified corn syrup, palm sugar,dextrin, fruit juice concentrate to name a few. People need to wake up. I learned the hard way. I got gout from drinking Vitamin Water-32 grams of sugar per bottle which equals 8 tsp. of sugar per bottle. Next time you buy pop or fruit juice or some processed food check for carbs. Our western diet is turning us into an obese society full of diseases. I find this very sad especially for the next generation. I truly believe a low carb diet could turn this around. I love Keto and all the great recipes and I will stay on it for the rest of my life. I am now off all medication and feeling great.
This is in part because patients need to be in deep ketosis to see an impact on epilepsy, likely deeper than the average dieter, but without a nutritionist guiding you it’s still hard to get down into ketosis. It’s not exactly clear why ketosis seems to improve epilepsy, but it seems to have something to do with the brain’s use of ketone bodies in place of glucose, which only happens when you’re nearly in starvation mode. (It's important to note here that "starvation mode" is not in reference to how hungry you feel.)

Ketone esters (BHB-BD) lowers blood lactic acid 30. Lactic acid build up occurs during exercise as a result of burning carbohydrate at a high rate without enough oxygen. Blood lactic acid levels during exercise were 30% lower after ketone ester drinks compared to carbohydrate drinks. This is because high blood levels of BHB from the ketone ester drink slow down carbohydrate use and increase oxygen efficiency, which could decrease blood lactic acid levels. 
Now, there a few things you should know before you begin using KETO//OS. First, ketones naturally act as a diuretic, so you lose salt, potassium, calcium and magnesium, and it is generally encouraged to increase sodium intake with ketones. That’s why there is extra sodium added to KETO//OS. The combination of BHB with sodium also acts as a bit of a buffer to buffer natural ketone acidity.
On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids.[56] Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.[55]
I am hoping that keto had nothing to do with it. He expressed to be on several occasions that he felt the best he'd ever felt in his life while doing keto. After he died I went to a cardiologist to be checked out and my heart is fine. Dr said he actually supports keto in the lean meat and veggies vs of it plus healthy fats. Not a ton of red meat etc. Also highly supports intermittent fasting.
Thank you soooooo much for your blog! I’m 35 and have struggled with loving myself and food now for over 20 years. I eat because I have to, not because I want to. I could go all day without even realizing I haven’t had anything to eat. I looked into maybe starting this diet, just to see if there was any benefits to it. After reading your blog I have realized how dangerous it could be for me.
Over the last few months, we have interviewed five people who have used the keto diet to each lose over 100 pounds. They shared with us the different kinds of life changing habits they developed along their keto journeys - the habits that kept the weight off. How do they deal with cravings? What was the hardest part? When did they decide to make a change? What do they eat every day? Listen to the interviews over at the Keto For Normies Podcast or stay and read them here! 
I think there is a different approach to weight loss that works for every person! So you have to find what works for you. I did this as a diet for 8 months and lost 56lbs about 5 years ago before it became as popular as it is now. I started it as 10 day detox then moved to paleo but my weight loss stalled. I knew that low carb had worked for me before but I wanted more whole foods. So in searching for low carb Paleo, I stumbled on Keto. I completely healed my pre-diabetes and sugar issues. Even after resuming “normal” eating. As I have seen this diet rise in popularity, I have seen so many different “styles” of it that don’t really make sense with what I knew it to be. I also think there are so many people who just jump on the bandwagon and want the quick facts, the meal plan, etc. I get that people are busy but this is YOUR body. DO YOUR RESEARCH. Any way of eating has an impact on your hormones and it is important that you seek out experts rather than rely on information passed to you from your neighbor’s sister. There is a reason that people become experts. Our bodies are amazing creations! An expert can look at your history and determine that you might have metabolic damage and until you reset it, you won’t experience weight loss. An expert can listen to your symptoms and tell you what is normal or what could be an underlying Thyroid issue. An expert can look at your goals and determine the right protocol. If you are a body builder then you will need some carbs. If you are just looking to lose weight then you could do strict keto. It’s not just about what food goes into your body. Also, there’s so many people who are just using it as an excuse to load up on steak, butter, and cheese (just like with Atkins). But you aren’t doing yourself any good if you aren’t getting GOOD QUALITY fats from things like salmon and avocado. Some excellent reading would be Carb Nite solution. He is a physicist and is able to tell you exactly what is happening in your body. Maria Emmerich is another GREAT ONE. Stephanie Ketogenic is a youtuber who has a vast amount of knowledge.

This article really bothers me in that if you do a few incorrect things with this diet, it will actually do more harm than a full carb diet. I have been in ketosis for a month or so but to what detriment? Based on the “ketosis darkside” list you highlighted, i could be doing any or all of these without realising. Could i share with you my meal plans and see if in your opinion they are beneficial and healthy or if im digging myself an early grave?


Ketones are produced if you eat minimal carbs and very moderate amounts of protein. On the keto diet, your body is fuelled almost entirely on fat. Your insulin levels drop and fat burning escalates. Optimal ketone levels are beneficial for weight loss, health, and also offer mental and physical performance benefits. You’ll be less hungry and also have a steady supply of energy.
If you want to try a ketogenic diet, be aware that you'll have to adjust it for your individual metabolism and experiment with the right balance of carbs and calories. While some low-carbohydrate dieters find they are able to break stalls in their weight loss, others find that it is more difficult for them to stay in this state. You may want to consult a registered dietitian to build keto-friendly menus for you that will meet your nutritional needs. Be sure to keep your health care provider informed when you start a new diet, especially if you have ongoing health conditions.
The latest — or maybe just loudest — diet obsession transfixing the internet says it will help you lose weight, live longer, and improve your memory. Sounds great, you say? Except that these benefits will only bloom once you cut carbohydrates. Familiar story, right? The Atkins diet is back? We’re all gonna start eating eggs and bacon for every meal again until our cholesterol inevitably reaches code-red levels?
Although fat is the centerpiece of any keto diet, that doesn't mean you should be subsisting on butter-topped steaks, says Kristen Mancinelli, RD, author of The Ketogenic Diet. “A big misconception is that you should just put meat at the center of your plate and add more fat on top,” she says. You also shouldn't be relying on fatty meats to hit your fat quota, she adds.

In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.[1]

For patients who benefit, half achieve a seizure reduction within five days (if the diet starts with an initial fast of one to two days), three-quarters achieve a reduction within two weeks, and 90% achieve a reduction within 23 days. If the diet does not begin with a fast, the time for half of the patients to achieve an improvement is longer (two weeks) but the long-term seizure reduction rates are unaffected.[43] Parents are encouraged to persist with the diet for at least three months before any final consideration is made regarding efficacy.[9]
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
The difference between ketosis and ketoacidosis is the level of ketones in the blood. Ketosis is a physiological adaptation to a low carbohydrate environment like fasting or a ketogenic diet. There are situations (such as treatment-resistant epilepsy) where ketosis can be beneficial to health. Ketoacidosis is an acute life-threatening state requiring prompt medical intervention; its most common form is diabetic ketoacidosis where both glucose and ketone levels are significantly elevated.
I see a lot of people say that ketosis is great for insulin sensitivity. BUT, in my experience ketosis causes physiological insulin resistance whereby the muscles and liver are sparing glucose for the brain. Hence, glucose tolerance actually goes down during ketosis. As such, is it possible that post workout carbs could do a lot more damage than they would on a non-ketogenic diet? Or maybe, as Kiefer suggests, glucose uptake post workout is not moderated by insulin at all i.e. muscles soak up glucose regardless of their insulin sensitivity? Or maybe cyclical ketosis doesn’t allow liver glycogen to get low enough to trigger physiological insulin resistance?
A systematic review in 2018 looked at sixteen studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients gave up with the diet, for various reasons, and the quality of evidence inferior to studies on children. Health issues include high levels of low-density lipoprotein (LDL), high total cholesterol, and weight loss.[23]
Diarrhea can also be due to a lack of fiber in the diet, says Kizer, which can happen when someone cuts way back on carbs (like whole-grain bread and pasta) and doesn’t supplement with other fiber-rich foods, like vegetables. It can also be caused by an intolerance to dairy or artificial sweeteners—things you might be eating more of since switching to a high-fat, low-carb lifestyle.
On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids.[56] Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose.

However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.[55]
A common belief among keto devotees is that your body not only switches to burning fat on keto but that a low-carb, high-fat diet turns you into a “fat-burning machine.” Now that you’re not eating pizza crust, your body is going to burn through all of its own fat, calories and laws of thermodynamics be damned. But you don’t magically burn off your love handles just because you changed your fuel source. As much as the three macronutrients have different uses in the bodies, when it comes to gaining and losing weight, calories are calories are calories.
Minerals/Electrolytes: Adopting a ketogenic diet will change the way your body uses (and loses) certain minerals. Not replacing these minerals can lead to symptoms of the “keto flu” such as lightheadedness, headaches, constipation, muscle cramps and fatigue. Refer to this article for tips on how to replace common minerals such as sodium, potassium, magnesium and calcium.
