I think you should take some of your own advice…you are being judgmental and thinking your diet will work for everyone. Look at the scientific facts; your body’s life blood is carbohydrates, the bread of life. Simple carbohydrates are what is killer to American society. Any diet that cuts out junk food like greasy potato chips and ice cream and cake will make you lose weight, not rocket science. Where do you think your body is getting fuel from? Muscle mass! It has to use that because you are depriving it of fuel! Why go on extreme diets when all you need to do is practice portion control and get up off the couch and walk around?
The catch, of course, is that if it sounds too good to be true, it probably is. And that’s exactly what hopeful dieters need to keep in mind when approaching the ketogenic diet (if we're calling it by its formal name). It’s not that this high-fat, moderate-protein, low-carbohydrate approach to eating can’t deliver weight loss in a delicious package, but it’s a restrictive, sometimes complicated affair that isn’t sustainable for most people.
Diabetes, whether type 1 or 2, are diseases extremely susceptible to the therapeutic level effects of diets that lower insulin. If those diets are also nutrient dense, evolutionarily matched to humans and produce a more generally preferable shift in metabolism, then all the better. This sort of dietary treatment for diabetes holds great promise in their potential for helping out in other diseases like cancer, Parkinson’s and Alzheimer’s disease.
If you’re wondering about the difference between ketosis and diabetic ketoacidosis, you’re not alone. “The word ketone is scary for most people with type 1 diabetes because they relate ketones to diabetic ketoacidosis,” says Patti Urbanski, MEd, RD, CDE, a certified diabetes educator with St. Luke’s Hospital in Duluth, Minnesota. “But with the ketogenic diet, we’re talking about a much lower level of ketones.”
Over the past century, ketogenic diets have also been used as natural remedies to treat and even help reverse neurological disorders and cognitive impairments, including epilepsy, Alzheimer’s symptoms, manic depression and anxiety. Research shows that cutting off glucose levels with a very low-carb diet makes your body produce ketones for fuel. This change can help to reverse neurological disorders and cognitive impairment, including inducing seizure control. The brain is able to use this alternative source of energy instead of the cellular energy pathways that aren’t functioning normally in patients with brain disorders.
When ever-increasing amounts of insulin aggravate insulin resistance, it only makes sense to keep insulin levels as low as possible. Does this make sense? You may notice that this is the exact opposite of the standard treatment for diabetics. They receive external insulin to overcome the inability of the pancreas to produce sufficient amounts of the hormone.
Fat (and the ketones produced from fat) are a readily available source of fuel. Once someone is fat adapted and in ketosis, they will find they can easily go hours (even days) without food and not have drastic energy level swings. And if someone is looking for a non caffeine, non-sugar 'pick me up' while in a ketogenic state, then supplemental ketone salts are the perfect answer.
The side effects of extreme low-carb diets are still a mystery. "The first major drawback is the fact that we really don't have any long-term research about how keto followers fare 10, 20, 30 years down the line," Turoff says. "What will the results look like? Will they regain the weight? Will they suffer health consequences? We also thought smoking and diet pills were a good idea, until long-term studies showed us that we were wrong."
The New York Times pieces also points out that studies are disproving this concern and making a case for both children and adults with type 1 diabetes to consider a ketogenic diet. Specifically, a 2018 study published in the journal, Pediatrics, which took a look at glycemic control among children and adults with type 1 diabetes who followed a very low-carbohydrate, high-protein diet. The researchers found that both the adults and children who consumed this diet along with smaller doses of insulin than typically required exhibited “exceptional” blood sugar control without high rates of complications. In addition, the study data did not show an adverse effect of a very low-carbohydrate diet on children’s growth, although more research may still be a good idea, according to researchers.

Here are a few of the most common side effects that I come across when people first start keto. Frequently the issues relate to dehydration or lack of micronutrients (vitamins) in the body. Make sure that you’re drinking enough water (close to a gallon a day) and eating foods with good sources of micronutrients. To read more on micronutrients, click here >
For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)
I have enough carbs in a day for all my needs. Just eating proteins alone raise the insuline level, enough for muscles preservation. And I top it with vegetables. I have more than enough. I just to be clear, I don’t think the human body is dumb enough to burn a lot of muscles when you have 100 pounds of stored fat. Why the body don’t store proteins, if it prefers that? Modern nutrition take our body – and us – for fools!
Diets require discipline, and it is not always easy for people to follow them without indulging in a "cheat day." One day may not make a big difference in the long-term, but a recent study from the University of British Columbia in Okanagan, Canada (UBCO), found that when it comes to the keto diet, a single dose of carbohydrates may have dangerous side effects.
Truly Dr. Colbert is also a reputable source for more thorough science and modification of previous Keto extremes. The statements about Keto diets with dairy everyday are not true…I am a 66 year old professional (University trained) and have found medical people often very unknowledgable or partially knowledgeable which may be worse. I ask you Abbey to dig deeper…meet Dr. Colbert-not a quack and more in depth than your overview. Personally I am finding switch to more green’s and low glycemic vegetables and fruits with healthy fats, occasional dairy and healthy protein; a way of life that is helping our whole family. Please watch The Magic Pill…the help for family’s caught in old thinking from poor science (ie. Alex Keys) and with autism etc. and so much modern disease is in itself, motivation to search out more truth.

But beyond that, experts aren't convinced that the keto diet has any other scientifically-proven health benefits. In fact, it may have some distinct downsides. If you follow the keto diet incorrectly, for example (like by eating lots of saturated fats, versus healthy unsaturated fats), you're at risk of raising your cholesterol levels. “The best strategy to keep your heart healthy is to get as much fat as possible from unsaturated sources such as olive, avocado and canola oils, nuts, seeds, avocados, and olives," says Ansel.

We have all heard of essential fatty acids (EFAs) and essential amino acids (EAAs), but have you ever heard of essential carbohydrates? No. The human body is capable of burning fat for fuel. If the body can burn fat for fuel, why would you ingest a substance (carbohydrate) that raises your blood sugar, raises your insulin levels, and makes you sick? Why would the ADA advocate the very diet that made us sick in the first place? When are they going to admit they’ve been wrong and start doing what is in the best interest of diabetics?
There are occasional instances of cardiomyopathies (heart muscle diseases, heart failure) and sudden cardiac death–The immediate causes are unclear, though at least some cases are due to severe selenium deficiency. The picture is muddied by the fact that some kids were fed large quantities of corn oil in past as a means of maintaining ketosis. Nonetheless, it suggests further uncertainties with prolonged ketosis.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
In addition, on the day the diet was initiated, diabetes medications were reduced – generally, insulin doses were halved, and sulfonylurea doses were halved or discontinued. Due to the possible diuretic effects of the diet soon after initiation, diuretic medications were discontinued if of low dosage (up to 25 mg of hydrochlorothiazide or 20 mg of furosemide) or halved if of higher dosage. Participants were also instructed to take a standard multivitamin and drink 6–8 glasses of water daily, and were encouraged to exercise aerobically for 30 minutes at least three times per week.
The keto diet is an ultra-low-carb and high-fat diet that restricts total carbohydrate numbers to just 20 or 30 net grams of carbohydrate per day. That’s the equivalent of a single piece of fruit or half a bagel. When you cut carbs, your body’s preferred source of energy, you require your body to suddenly shift to fat for fuel. This raises blood levels of ketones and puts you in a state of ketosis—hence the name “keto diet.” Once this shift, happens, you will lose weight, but you may also have experience so negative side effects. This is commonly referred to as the keto “flu.”
More recently, a meta-analysis was published in the Journal of Neurology that assessed the impact of the ketogenic diet in treating epilepsy. It included a total of 19 studies with a total of 1084 patients. After analyzing the data, the researchers noted that the patients who stayed on the diet had a 2.25 times greater probability of treatment success (at least a 50% reduction in seizures).

I won’t comment on the diet itself but dietitians do not simply rely on guidelines handed to them, nor on anecdotal cases. This article refers to specific studies all throughout, some that support the diet and others that don’t. The goal of a dietitian is to help clients reach their optimal health while still enjoying a high quality of life. I’m sure Abbey is genuinely happy for those it has helped. That does not mean this diet is best for everyone regardless of their unique circumstances, goals and medical history. Sadly there is not enough high quality research that Keto promotes sustained weight loss in the general population. Maybe there will be in the near future, but right now it would be unethical to recommend such a restrictive diet to the broad audience of a blog. I am truly happy it has worked for some people and I wish them luck on their journey. Thank you Abbey for a great article!
The only issue with keto, is really that I’m afraid that it might be hard to up my calories to a maintenance weight now that I’ve gotten a taste preference for the rich assortment of foods with no carbs in them. I’m satisfied with less calories than I will need after my excess fat is burned off… but , maybe I bet my body will send more hunger signs once there isn’t anymore body fat in the cupboard to use instead of what goes down my throat.
Also, diabetics should not undertake the diet without medical supervision. “Trying a ketogenic diet has the power to drastically and quickly lower blood glucose levels,” says Santos-Prowse. “If a person with diabetes is taking blood glucose-lowering medications, their doctor needs to be on board to help with adjusting or stopping the medications as needed.”

For my own children, I weighed them during this process and my two that were about 80 lbs both lost just under 3 pounds, and my 35-pounder lost 1.5 pounds the first 5 days. How do  I know it’s water weight? Because if it was fat, they would have lost the equivalent of over 5,000 calories (my little guy) or 17,500 for my olders.  There is no way they ran a calorie deficit in this amount in just 5 days ;)

If you haven’t already jumped on the keto diet bandwagon, I’ll give you a brief introduction. Basically, the ketogenic diet is a super high in fat (65-75% of your diet is fat), a super low carbohydrate (<5% of your diet) and moderate in protein (15-20% of your diet). Surely, not the most balanced of diets considering Health Canada   your diet should contain 10-35% of protein, 45-65% of carbohydrate and 20-35% of fat. So how to you meet that skewed macronutrient distribution? Well, you load up on keto diet staples like meat, fish, butter eggs, cheese, heavy cream, oils, nuts, avocados, seeds and low carb green vegetables. And you cut out all your go-to carb sources like grains, rice, beans, potatoes, sweets, milk, cereals, and fruits. These kinds of restrictive diets tend to make nutrition professionals like dietitians run for the hills but I’m going to give it my honest unbiased account.

ME: There is a sort of three-phase process the body goes through as it adapts to burning fat as its primary fuel. After two to three days, you will show elevated ketones [the buildup of chemicals created by the body when it burns fat for energy] in the blood. Energy will be low for the first week or two, but keeping electrolytes up such as sodium, magnesium, potassium [by using sea salt liberally and considering a supplement if necessary] and drinking water usually help. After about four to six weeks, the body actually makes more mitochondria [the powerhouses of our cells], and that is when your energy starts to soar. You also start seeing amazing mental clarity and focus, cravings go away more and more.

Dr. Campos, it is unfortunate that you retain the medical community’s negative stance on the ketogenic diet, probably picked up in medical school when you studied ketoacidosis, in the midst of an obesity and type II diabetes epidemic that is growing every year, especially among populations who will never see the Harvard Health Letter. The medical community has failed in reversing this trend, especially among children, and the public is picking up the tab, in the form of higher health insurance premiums to treat chronic metabolic diseases which doctors cannot cure. The ketogenic diet does not bid its adherents to eat unhealthy processed meats, and the green leafy vegetables that it emphasizes are important in a number of nutritional deficiencies. People lose weight on the ketogenic diet, they lose their craving for sugar, they feel more satiety, they may become less depressed, their insulin receptors sensitivity is improved, and these are all the good outcomes you fail to mention. There is a growing body of research which demonstrates the neuroprotective effects of the ketogenic diet to slow cancer progression, as well as diseases like Parkinson’s and Alzheimer’s, for which there are no effective medical treatments. Please respect your patients by providing them with evidence-based medical outcomes, not opinions.
This was a great read. I aim to restrict carbs always because I believe most are why the American population is obese. I would very much like to hear more about carb restriction excluding the discussion on processed meats and processed high salt content foods because I consume neither. I also don’t consume dairy or eggs. So can you provide some substance.
Well… what are many people on a Keto diet trying to do? Lose weight right?  I would guess that prior to discovering the Keto diet many of these people were caught in the trap of low fat dieting.  This lead to months or years of low fat intake and consequentially low gallbladder activity.  The gallbladder wasn’t needed to digest fat and so it sat idle and stones were more likely to form.  Once they made the shift to a ketogenic lifestyle and their fat consumption increased upwards of 1000%, the gallbladder kicked into high gear.  If the previous period of low fat dieting had caused stone formation they are going to have to deal with flushing those stones out now while on a high fat Keto diet.
Heart disease. The connection between the ketogenic diet and cardiovascular disease risk factors is complicated. Many studies have found that the keto diet can lead to significant reductions in total cholesterol, increases in HDL cholesterol levels, decreases in triglycerides levels, and reductions in LDL cholesterol levels, as well as potential improvements in blood pressure levels.
"On a ketogenic diet, your intake of fruits and vegetables is extremely limited, and we all know how important the fiber, vitamins, minerals, and other compounds in fruits and veggies are," says Libby Parker, R.D., a dietitian who specializes in treatment and prevention of eating disorders. It's true: There are a lot of healthy but high-carb foods you can't eat on the ketogenic diet. That's one of the reasons keto is usually pretty low in fiber, which isn't so great long-term. "Fiber is not only protective against many gastrointestinal cancers, it is also a big factor in fullness and weight loss," Parker explains. "Furthermore, constipation is very common on low-fiber diets like the keto diet." (That said, These Healthy, High-Fat Foods Can Help You Feel Full Longer.)

But what I think is funny is that the keto diet has been staring us in the face forever. Look at Inuit tribes that survived off of blubber in a region that grows next to nothing most of the year. Yet their people didn’t die out or show signs of metabolic disorders or heart disease until introduced to the modern western diet that prioritizes carbohydrates over fat. Here is an interesting link, however I find the conclusion disheartening and frankly more than a little suspicious. (Basically the people in charge decided to drop the study and introduced a bunch of “what about…” questions to obfuscate a clear pattern in observation across many indigenous people from across the face of the planet and decided the outcome “wasn’t enough” to introduce into public policy…)


On a low-carb ketogenic diet, your largest dietary food source should be healthy fats. Make sure to choose fats from a variety of sources, including oil, butter, fish, nuts, and seeds. Your body needs the different nutrients each type supplies. No more low-fat or non-fat foods! Remember: Not all fat is bad. Healthy fats are non-hydrogenated, cold-pressed, and plant- or seed-based.
Carbs turn into glucose (aka sugar) in the body. Eating too many carbs causes your blood sugar to spike. When you switch from carbs to fat for energy, you stabilize your blood sugar. Keto can be particularly beneficial for diabetics, who have high blood glucose levels. The keto diet may even cure diabetes — many diabetics are able to come off their medication when switching to keto. Find out more about keto and blood sugar here.

Most anyone who has struggled with keto side effects or just hasn’t felt good on a ketogenic diet stands to benefit greatly from exogenous ketones during the adaption phase and beyond.  Additionally, for people who have poor liver or gallbladder function, have poor mitochondrial health, or have never tried a ketogenic diet; the process of producing ketones can be stressful.


It’s also common for people starting the diet to experience flu-like symptoms, such as headaches and fatigue. This side effect is so common that there’s a name for it: the keto flu. “You shed a ton of water weight at first, which can lead to dehydration,” Nisevich Bede explains. This can worsen the symptoms of the keto flu. To counter it, she recommends staying hydrated and loading up on electrolytes through electrolyte tablets.
Although the ketogenic diet has been a source of controversy and debate, one cannot dispute its astounding health benefits. Initially, it was created by specialists at John Hopkins Medical Center, particularly for individuals who have epilepsy. The researchers established that fasting enhanced the number of seizures the patients experienced. Nonetheless, since fasting isn’t an accomplishable purpose nowadays, a diet has been developed that would trick the body into believing it was in that process.
The keto diet gained most of its attention for its role in the nutritional management of epilepsy and Alzheimers. More recently, science has shown positive clinical outcomes for a number of types of cancers through its ability to minimize tumor growth. In the case of all three of these diseases, ketones are therapeutic through providing an alternative substrate to glucose.
The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did not produce any significant side effects in the patients. Therefore, the present study confirms that it is safe to use a ketogenic diet for a longer period of time than previously demonstrated.
“Certainly, the quality of fat counts,” says Yawitz. “There’s a big difference nutritionally between bacon and almonds. As much as possible, people set on the keto diet should emphasize plant-based, unsaturated fats like nuts, seeds, olive oil, and avocado, which have even been shown to protect the heart.” If you have high cholesterol or other risk factors for heart disease, you should speak with your doctor before beginning the keto diet. This is because the diet may — but doesn't have to — include large amounts of saturated fat. Some studies have shown increases in cholesterol and triglycerides in people following the diet, while other research reveals that the keto diet may actually decrease heart disease risk as well as saturated fat intake.
Although many proponents recommend this high fat version of Keto for weight loss, it first gained notoriety as a treatment method for Epilepsy. Going as far back as the 1920’s, medical professionals have recommended high fat Keto Diets as a treatment method for difficult to control seizure disorders. However, a diet that includes a high percentage of fats as part of its eating program increases the daily caloric intake. More calories means slower fat loss. Therefore, the higher calorie count is why this Ketogenic Diet type is considered a slower weight loss model for dieters and is why the Ideal Protein Protocol is a more effective Keto Diet for weight loss.
One of the boldest claims about the keto diet is that it can help combat cancer by effectively "starving" cancer cells. It's a claim based on a phenomenon dubbed the "Warburg effect", which, in simple terms, describes how cancer cells are more reliant on sugar than healthy cells. So, the idea is that sticking to a low-carbohydrate diet will make it harder for cancer cells to thrive.
There is one precaution with keto and children who are under their ideal weight, though, and you will need to decide if the risks outweigh the benefits – being in ketosis is a natural appetite suppressant.  This will vary from person to person for how much this affects them, but if your child seems even affected by this appetite suppressant property, you may find that the GAPS or SCD diets are a better fit for healing the gut and encouraging weight gain. 
Finally, while it's something of an understudied phenomenon, some people who embark on a keto diet experience a bout of flu-like symptoms (often referred to colloquially as "keto flu"), as your body deals with the shift from crabs to fats as a primary fuel source.  “This has to do with fluid regulation when starting out. As your body adapts to running on fat, you excrete more sodium which makes you feel run down. Increasing fluid and salt intake generally help with this,” Fontaine says.
My biggest beef with this diet is that it focuses on how much and what you can eat and less about the quality of the food you eat. A recent 2018 study found that people who focused on eating plenty of vegetables and whole foods and less on counting calories and limiting food groups, lost a significant amount of weight over the course of a year. This continues to echo the notion that the key to successful weight loss is diet QUALITY and not QUANTITY. And now, there’s research that actually supports that!
I was diagnosed with Type 2 diabetes back in June, 2017. They wanted to put me on a special diabetic diet, and have me take two medications. I had done previous personal research into ketogenic diets. I also have a close friend who was diabetic, on meds, as well as medications for high blood pressure. He went on a ketogenic diet, and a few months later was off all of his medications.
Plagued by pimples? You may start to notice a difference in your skin on the keto diet, especially if you were a former sugar addict. Consuming lots of empty carbs is linked to worse acne—in part because these foods trigger inflammation and signal the release of hormones that up the production of pore-clogging oils, according to a review published in the Journal of the Academy of Nutrition and Dietetics. Some findings suggest that curbing your carb intake could help solve these problems, improving your skin as a result.
I suggest you or other readers who are not familiar with Dr Wahl's work and research into autoimmune disease and brain biology get a copy of 'The Wahl's Protocol'. Medicine and nutrition are ever-changing sciences and sadly we can't rely on our standard medical practioners (or registered dieticians) to share important research we should all be able to access.
Hi, I’m Bhuboy. Nutrition became my biggest passion after getting my blood chemical result showing my LDL cholesterol level over 481. I wanted to create a site where I could help you, my readers live a healthy and nutritious life. I believe we control our destiny, and we can choose to live a long and healthy life by eating right and treating our bodies with respect.
Cancer cells express an abnormal metabolism characterized by increased glucose consumption owing to genetic mutations and mitochondrial dysfunction. Previous studies indicate that unlike healthy tissues, cancer cells are unable to effectively use ketone bodies for energy. Furthermore, ketones inhibit the proliferation and viability of cultured tumor cells.
After reading that article I have to say that the “USC experts” are full of it. It’s the usual scare stuff that the mainstream docs and dietitians trot out to attempt to discredit LCHF and keto diets. There’s no reason why a keto diet should be any worse for bone health than any other diet provided it has adequate calcium, phosphate and Vit K2 and you have good Vit D levels. As for the recommendations of dietitians – eat lots of healthywholegrains and “vegetable” oils but no saturated fats – we know what the long-term results are of that: diabetes, heart disease and osteoporosis.
A keto diet was/ is not just used for diabetics. It is a very useful tool for epilepsy. It is extremely successful in reducing the number of seizures per day, mainly in children but also in adults. I am sure that followers of the epilepsy diet, which has been used since the 1920s have not all starved to death. Iwould also think that the followers of this diet are also motivated to stay on it, not eat a slice of birthday cake and keep all thier brain cells.
Diet Doctor has a number of videos and posts about positive impacts of the ketogenic diet for migraines, brain cancer, and traumatic brain injury. Recently, two psychiatrists reviewed the research base for psychiatric issues and noted that while promising, it is slim. Dr. Ede takes a more hopeful view. “My mantra is that the most powerful way to change your brain chemistry is by food, because that’s where brain chemicals come from in the first place,” she says.
