Missing Nutrients. One of the biggest concerns for dietitians is the keto diet’s lack of key foods. Many question the eating plan’s impact on the development of certain chronic diseases. Without milk, for example, getting enough calcium and vitamin D for sturdy bones becomes a challenge. Take away whole grains, fruit, beans, and potatoes, and it’s nearly impossible to consume enough potassium for healthy blood pressure or enough fiber to stay regular. And unless you’re eating lots of low-carb, leafy green vegetables, you miss out on vitamins A, C, K, and folate, too. 
No one is trying to diminish your success, but it does not work for everyone, and studies show it can have long term negative effects on your overall health. If you look at the Meta-analysis it shows a calorie restricted diet and Keto for 12 weeks had the same weight loss. There are also many studies that suggest looking back at people after one year those on a calorie restricted diet kept more of their weight off. The only one it does better than is just a low fat diet, which Dieticians stopped suggesting long ago. And as Health Care professionals we read the “REAL SCIENCE” not the internet articles, You Tube, Blog, book writers. One of the books written about it by Dr. Jason Fung. Have you looked him up on PUBMED? He has not written one article published in a real medical journal to be such an expert. It is not magic, it is not a cure. If you like the diet and it does not mess up your cholesterol then so be it but promoting it to others not knowing their medical history can be dangerous. What people don’t realize is that for year’s we have known that if you lose 7-10% of your own body weight your blood sugars will improve, cholesterol, and blood pressure. But you don’t have to do the fasting and put more burden on your Liver or potentially increase your risk for cardiac problems eating such high fat. If you do high fat at least do plant fats and not animal fats. But of course everyone is happy with your success but just keep a tab on your lab work.
Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.
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.

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.
They focus on what to eat instead of what not to eat, according to Dr. J. Michael Gonzalez-Campoy, medical director and CEO of the Minnesota Center for Obesity, Metabolism, and Endocrinology, who worked on healthy eating guidelines with the American Association of Clinical Endocrinologists, the American College of Endocrinology, and The Obesity Society.
And while some fats can be healthy, there’s a risk that in following a high-fat diet, you’ll increase your intake of unhealthy trans and saturated fats. These “bad” fats are found in things like red meat, poultry skin, cheese, and butter, and can lead to an increase in LDL, or “bad” cholesterol and increased risk of heart disease. (14) This is a controversial issue, as some experts do recommend adopting a low-carbohydrate diet to lower heart disease risk. If you’re at risk or have heart disease, it’s important to speak with your doctor first about your health needs.
An extensive review published in 2013 looked at the research and evidence of ketogenic diets enhancing fertility (long story short, it looks promising). Studies also show that Polycystic Ovary Syndrome (PCOS) can be treated effectively with low-carb dieting, which reduces or eliminates symptoms such as infrequent or prolonged menstrual periods, acne, and obesity.
Diets that focus on lowering carbohydrates and increasing fat have been associated with lower levels of “bad” cholesterol and higher levels of “good” cholesterol. Furthermore, lower triglyceride levels are typically seen in those on a ketogenic diet. A better cholesterol balance and fewer triglycerides can help to protect against plaque deposition in the arteries, which can lower your risk of atherosclerosis, heart disease, heart attacks, and stroke.
As the popularity of the Keto Diet has exploded in recent years the true nature of Ketogenic weight loss has gotten blurred. So what is Keto? Very simply Keto refers to Ketosis, the state into which your body enters when it shifts to burning fat for energy instead of carbohydrates. As carbohydrates and sugar intake is restricted, your body begins to break down its fat stores to use as a source of energy. Therefore, the very basics of a Ketogenic Diet are:
The keto diet is one of the hottest weight-loss strategies today. That’s not surprising—who wouldn’t want to lose weight fast without counting calories or feeling hungry? But it’s not without controversy: Yes, you can eat all the fatty foods you want, but the tradeoff is the extreme restriction of carbohydrates: bread, potatoes, even fruit. Keto dieters are advised to keep carbs to just 10 percent of their daily intake.
.. it can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. What is unhealthy about red meat. We should know that acrilamides, pyrroles in burnt meat (and veges) from BBQ and over-heated cooking inflames the colon. According to Clark H R, PhD ND an inflamed part allows easy entry for the cancer nucleus and cancer complex, to start and fuel a malignancy at that location.

Although we love them to death, our Mom’s typically have zero authority on the subject.  When Mom heard you were going on a ketosis diet the first thing she did was head to google hell bent on finding any information about the dangers of the diet.  Sure enough, 10 pages into google she found what she was looking for… Never mind the first 9 pages filled with information about the safety and merits of the diet.
I’m in ketogenesis now – 3 weeks in. Lost over 10kg. Protein shakes. Great. But what I wanted to add was that i’m Diabetic (2) and quite badly so. I was Injecting insulin twice a day – Novomix (part immediate, part slow acting). But since I went into keto, my blood sugar has been steady between 5-9, normal range. No injections needed. And no hypo attacks either – that occurs below a reading of 4, for me. This is NOT a cure of course – it’s directly related to low carb intake. But I do wonder if discontinuing insulin is partly responsible for my improvement in alertness, activity level and so on. Magnesium tabs, 1000 units twice a day, have also been helpful – I suffer leg and foot cramps due to spinal arthritis – but they had worsened until I upped the dose.
Another earlier study published in the journal, Nutrition and Metabolism, finds that both a low-glycemic index, reduced-calorie diet and a low-carbohydrate, ketogenic diet can improve glycemic control, encourage weight loss, and reduce or eliminate the need for diabetic medication over a 24-week period with the lower carbohydrate keto diet being “most effective for improving glycemic control.”
Originally Ole Jørgen took little to no medication for his bipolar illness, now he only carries medication as a safety precaution, in consultation with his doctors. Now he finds that with his ketogenic diet, exercise and good sleep his moods are predictable and stable. In short, life is good. He is reaching out to friends more. “I even met a girlfriend and we have started a good relationship.” He plans to run the New York City Marathon in the fall of 2018, another first for him.
Beyond the short-term effects of the keto flu, the diet can also negatively impact your digestion and gut in the long run. One 10-year study conducted on using keto to manage pediatric epilepsy found the following GI side effects over time: constipation, high triglyceride levels, high cholesterol, diarrhea, lethargy, iron deficiency, vomiting, and kidney stones.
Until recently, ketosis was viewed with apprehension in the medical world; however, current advances in nutritional research have discounted this apprehension and increased public awareness about its favourable effects. In humans, ketone bodies are the only additional source of brain energy after glucose (23,24). Thus, the use of ketone bodies by the brain could be a significant evolutionary development that occurred in parallel with brain development in humans. Hepatic generation of ketone bodies during fasting is essential to provide an alternate fuel to glucose. This is necessary to spare the destruction of muscle from glucose synthesis.

Examples include non-starchy fruits and vegetables such as leafy greens, mushrooms, bell peppers, and berries. The trace minerals and vitamins found in grains can also be obtained at higher percentages in good-quality meats and dairy products. Moreover, compounds such as phytates and tannins in grains hinder the bioavailability of several minerals.13
If you want to use a ketogenic diet as a health tool, it would be wise to do so for no more than a few weeks at a time, as nobody knows how long is too long. And, of course, the period of time during which ketosis is safe can vary from individual to individual. Breaking ketosis is as easy as upping protein intake or having a glass of wine or whole piece of fruit.
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.
One way to find out if the keto diet is not be ideal for your cardiovascular health is by checking if your total-to-HDL cholesterol ratio is above 4 and/or your LDL-P remains high or increases after starting the keto diet. If this is the case for you, then you may fare better with a low to moderate fat diet with plenty of whole foods, fiber, monounsaturated fats, polyunsaturated fats (especially omega 3s), and limited saturated fats.
These are the daily calorie recommendations for average weight/heigh children of these ages. When a range is given, it depends on the activity level. Female children have lower calorie needs than male children once they reach 5 years, averaging 100-300 calories/day less for the same amount of activity, other than ages 19-20, which I have noted the significant differences in.
Our body needs some time to get used to ketones being elevated in the blood stream to begin using them effectively and efficiently for cellular energy.  By consuming an exogenous ketone supplement, you get the body adapted to ketones faster and using them as an energy source before the body has built the metabolic machinery to produce its own ketones effectively. 

I am a T2D, finally fully keto starting at the end of March. I am down 28 lbs. My goal is 50, so I am feeling encouraged and fitting into smaller sizes already. In May my A1C was 5.6. This morning, according to a home test kit I purchased from CVS, my A1C is 5. I believe that is fairly accurate based on my blood sugar readings, which are staying well below 100.

Yes!! Edward!! I am pre-diabetic myself and have IBS which many doctors have no explanation for many of my questions because IBS triggers everyone differently and with different foods. I have been keto for 6 weeks and have lost 14lbs and have not noticed any symptoms of IBS even when I eat trigger foods (onion/garlic) I am no means 100% keto yet because I have had slip ups here and there but I jump right back in. I can’t imagine not following this way of life moving forward. I immediately feel the difference if I indulge in anything more then I should. Im learning to listen to my body and now see carbs/sugar is what has been causing madness on my body. Keto-on Edward!
You’re a diabetic counselor and are talking about being worried about not being able to eat birthday cake? Hell I’ve been on keto since July 2016 and haven’t felt any urge to go back, simply because I feel so much better. Also the diet is really not all that restrictive, you can make desserts using stevia/erythritrol, coconut/almond flour, etc. I had ketogenic pizza the other night and it turned out great. Lots of great resources out there for food options. I’m not diabetic myself, but I used to be prone to hypoglycemia and keto has eliminated the issue since I’m not dependent on glucose. There are a lot of wrong ways to do keto though, and doing the diet correctly has a moderate learning curve.
In a March 2018 blog post, Dr. Ede provides a range of very helpful tips for anyone already on mood-altering or psychiatric medications who want to try a ketogenic diet, such as how to talk with your psychiatrist or mental-health provider and what laboratory metabolic tests the doctor should order to help monitor your response to the diet. Most importantly, she provides details about some specific medications — notably specific antipsychotic medications, anticonvulsant medications, and lithium — that should be carefully monitored.

Regarding keto diets specifically, studies have proven this method to be more effective than moderate protein diets in lowering blood glucose, promoting weight loss and lowering HbA1c in patients with Type 2 diabetes. A growing number of clinicians now agree that low-carb diets can effectively treat this disease. The fact remains: these diets remain controversial and contradict dietary guidelines, so they are not very often discussed or recommended in the clinical setting.
I’ve been on the keto diet for about 3 months now. When I first started, I read all that I could online and a lot of the information is conflicting. One of the biggest mistakes that people make on the keto diet is thinking that they can eat all the fat they want and still lose fat, and that just doesn’t happen. Another one is that you should keep your protein consumption low and that is not correct either. The proper way to a keto diet is to consume 1 gram of protein per lean body weight, and keep fat under 100 g per day if you’re looking to lose fat. Also a weight lifting program helps tremendously, and you will gain muscle and lose fat at the same time instead of losing all that fat and then becoming a flabby skinny person.

After about two to seven days of following the keto diet, you go into something called ketosis, or the state your body enters when it doesn't have enough carbs for your cells to use for energy. That's when you start making ketones, or organic compounds that your bod then uses in place of those missing carbs. At this point, your body also starts burning fat for more energy, says Beth Warren, R.D., founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.
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.
Nutritionists frequently advise clients to reach for more healthy fats and protein to stay full throughout the day. With this in mind, it makes perfect sense that a ketogenic diet would be about as good as it gets for staying satiated. One study from the American Journal of Clinical Nutrition found this type of low-carb approach was more effective for weight loss and managing hunger than a similar high-protein diet with a greater percentage of carbohydrates. One 2013 study even suggested the eating plan may suppress hunger hormones more effectively than other weight-loss programs.
I’m not Edward, but I’ve been on a keto diet for 3 weeks. I don’t find it difficult at all. I’ve attended 2 birthday parties, and it’s easy to say “No thank you” when I’m offered cake because my health is my top priority. Drinking a lot of water to support the kidneys is an absolute must. Also, supplementing sodium, potassium and magnesium keeps electrolytes in balance. A Naturopathic doctor is a great source of information on true lifestyle modifications.
The keto diet is NOT what you seem to picture. I laughed at your description as I was eating lamb chops, cauliflower rice, broccoli, followed by cheesecake. How deprived I was! You should relook at what the diet really is. By the way, my cardiologist highly recommends keto. Most people see a drastic decrease in their triglyceride/HDL ratio. Looking at total cholesterol or LDL alone is 20 years out of date! Even the AHA has caught up, and now says that it’s NOT how heart health should be judged.
I came here to say similar things, OP. Whoever wrote this article obviously has an agenda and is conveniently over-looking evidence and stories from people like you. I especially like the part where she claims keto isn’t sustainable because “Oh My God, I can’t not like eat bread, like for the rest of my life, lol” and “YOU’LL GAIN ALL THE WEIGHT BACK IMMEDIATELY IF YOU HAVE A CHEAT DAY!!” This article was a great laugh. I came here to get educated but am quickly learning you can’t always believe what a random dietician says on the internet. Happy KETO and congrats on your success! 

You’ve lost weight. By far the most common cause of unexplained hair loss is simply rapid weight loss or dietary change. This disrupts the normal growth and decline cycle of your hair follicles, shunting a greater proportion of them into the “rest” phase to be pushed out by incoming hairs. Even though you may see extra hair in the shower or on the brush, your actual hair thickness shouldn’t change much.

Eating cholesterol has very little impact on the cholesterol levels in your body. This is a fact, not my opinion.  Anyone who tells you different is, at best, ignorant of this topic.  At worst, they are a deliberate charlatan. Years ago the Canadian Guidelines removed the limitation of dietary cholesterol. The rest of the world, especially the United States, needs to catch up.

When you restrict carbohydrates, the body begins to process electrolytes in a different way. This is because, under conditions of low insulin, the kidneys excrete more sodium. Since there is a delicate balance between sodium and other electrolytes in the body, this increase in sodium excretion can have a knock-on effect and disrupt other electrolytes as well.


If Doctor’s recommend Keto to their patients that less drugs and no kick back from pharmaceutical companies, they need to keep people medicated because pharmaceuticals run this entire country. I followed a strict diabetic diet when my husband was diagnosed with Type 2 NEVER could keep his blood sugars under control still would be 220 after a meal.. Keto has brought that down to 95-98 AFTER a meal.

According to Dr. Cabeca, “Fasting is a key aspect of a healthy diet and has many anti-aging effects.” In particular Dr. Cabeca recommends fasting to women during or after menopause due to it’s anti-aging effects. For example, a 2016 study published in the Journal of the American Medical Association found that when women went 12.5 hours between dinner and breakfast (a common form of fasting), the overnight fast seemed to help improve immune system functioning to the point that it reduced their risk for breast cancer. (03) 


Constipation is the rule–as virtual elimination of dietary carbohydrates also means virtual elimination of prebiotic fibers that nourish bowel flora. Over time, this leads to metabolic distortions including a drop in HDL cholesterol, rise in triglycerides, rise in small LDL particles that lead to heart disease, rise in insulin resistance and blood sugar, rise in blood pressure, even if these parameters initially improved on the diet. This is also due to dysbiosis and lack of prebiotic fibers. While this has not yet been tracked in children, in adults we can expect that these distortions in bowel flora will, over time, also lead to heightened inflammation (bowel and elsewhere), diverticular disease (.e.g., diverticulitis), and colorectal cancer. Yes: prolonged ketosis can add substantially to risk for colon cancer. Other peculiar gastrointestinal complications of prolonged ketosis have also been observed, such as protein-losing enteropathies.

Early research suggests that the keto diet may slow the growth of cancerous tumors. “Cancer cells have plenty of insulin receptors on them, making them flourish in environments high in blood sugar and insulin,” says Brandon Olin, host of The Deskbound Podcast, which focuses on overcoming the damage of a sedentary lifestyle. “It’s essentially giving cancer cells a source of fuel to feed on and grow.” The research suggests ketone bodies may provide energy for your body without feeding the tumors.

In these cases, exogenous ketones can be powerful. Exogenous ketones are a supplement that can be used to supply the body with a source of ketones that require almost no processing by the digestive tract and liver. This makes them great not only for helping someone get into ketosis, but also as a quick energy source and performance enhancer for brain and body.
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.

First of all, I can’t deny the fact that people will lose weight on a keto diet. Here’s why. First of all, you’re eliminating a major food group. When you do that, you limit your food options and most likely your food intake, so it’s not rocket science that you’ll likely lose weight. Second, most people on a low carb diet tend to increase their protein intake in the absence of carbs and there is some evidence that consuming higher amounts of protein may have some weight loss benefits. The large recent study mentioned above also looked at fat loss and found that individuals following a keto diet lost about the same weight as individuals following a different diet when they ate the SAME amount of calories. However, the studies found that individuals on the keto diet tended to lose body weight quicker.

Yancy has seen similar results in his practice. “Carbohydrate intake is the main driver of blood sugar. So if you’re able to lower blood sugar by reducing carbohydrate intake, then you may be able to reduce diabetes medication,” he says. “We’ve seen people come off of hundreds of units of insulin just by changing the way they eat, and that can happen really quickly, in just a few weeks.”


It’s no secret that carbs—especially refined ones like sugary cereals, white bread and pasta, or sweet drinks—cause your blood sugar to spike and dip. So it makes sense that eating less of them can help keep things nice and even. For healthy people, this can translate to more steady energy, less brain fog, and fewer sugary cravings, Mancinelli explains.

It is important to understand that the statement that carbohydrates are “nonessential” is not only factually inaccurate, it results in adopting a low-carbohydrate diet or ketogenic diet that increases your risk for a wide variety of chronic health conditions that may ultimately shorten lifespan, decrease your quality of life, and accelerate your risk for chronic disease.


The ketogenic diet is a low-carb, high-fat diet, similar to a number of popular diets such as the Atkin’s diet. It is primarily known as a weight-loss diet, as it can help boost the metabolism and speed up the burning of calories. While many people think of a high-fat diet as being unhealthy, it is all about the type of fats that you consume. In a ketogenic diet, for example, your protein intake will be quite high, rather than having a carb-heavy diet. Both carbs and fats can be used by the body for energy, but when fat is the primary source of energy metabolism, the body enters a state known as ketosis.
I told the nurse that I would not take the medications, and I would manage it with diet. She looked at me skeptically, and said “I would not recommend that.”. They had me scheduled for a follow up in a month and a half, so I told her that I would do my own thing for that time, and if my numbers did not improve, we could discuss the medication further.

The keto diet also has an impact on our hormonal levels. Many studies have looked at whether the state of ketosis suppresses our appetite through the actions of leptin and ghrelin. A 2013 study found that after patients lost weight on a keto diet, our hunger hormone (ghrelin) was altered and suppressed. A systematic review also concluded that the state of ketosis appears to be a plausible explanation for the suppression of appetite. So this the keto diet may be good for dieters who can’t stand the discomfort of hunger. Finally, the keto diet also may have an impact on our stress hormone, cortisol. This was demonstrated in a Harvard study where the keto diet resulted in an increase in cortisol in individuals following a very low carb keto diet. High levels of cortisol is associated with insulin resistance, cardiovascular disease and may promote fat accumulation.

I am a 7 year stroke survivor that is partially paralyzed from the stroke. I work part time and while working I walk at least 2 miles at work three to five times per week, but I can only walk 1 mph if even that speed. Which I know average speed is 3 mph when walking. I am 40 pounds overweight due to not being to do cardio workouts. I take aspirin daily as a blood thinner. I have considered getting on the keto diet. I drink sweet tea and one dr pepper per day along with coffee and water. I talked to my dr about this diet all he could tell me was he hasn’t researched it enough but knew of someone that lost weight on it. For my health I need to maintain a healthy weight and not be overweight. I have a b12 deficiency along with folic acid. I have not been taking any supplements for either.
