At any given intensity, a keto-adapted athlete burns more fat and less glycogen than a sugar-burning athlete. Long-term elite keto athletes can burn up to 2.3 times more fat at peak oxidation and 59% more fat overall than non-keto athletes, and they do it at higher intensities. They remain in the predominantly fat-burning zone at 70% of VO2max, whereas non-keto athletes switch over from predominantly fat burning to a spike in sugar-burning at 54.9% VO2max.
I have patients that have lost tons of weight on keto. They do go off some meds. I also have people who eat a moderate amount of good carbohydrates, and they have lost tons of weight, and been taken off meds, had improved markers, even reversal. I think both approaches work, as I have seen in practice. Many people cannot stay on a keto diet forever. I for one, prefer to have some carbohydrates. I try to pick the right ones. If this works for you, then just be sure to have some medical supervision, which it sounds as though you are doing.

To say that the keto diet has become one of the most popular diets of recent years is a complete understatement. Case in point: There are more than one million searches on Google every month for the keto diet. It’s unique because the fad diet has captured the interest of people who want to lose weight — and there’s no shortage of reported success stories to be found.
The key of these miraculous healing effects relies on the fact that fat metabolism and its generation of ketone bodies (beta-hydroxybutyrate and acetoacetate) by the liver can only occur within the mitochondrion, leaving chemicals within the cell but outside the mitochondria readily available to stimulate powerful anti-inflammatory antioxidants. The status of our mitochondria is the ultimate key for optimal health and while it is true that some of us might need extra support in the form of nutritional supplementation to heal these much needed energy factories, the diet still remains the ultimate key for a proper balance.”
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
Despite its explosive popularity, there’s a lot of confusion about what the ketogenic (keto) diet really is. “Many people think they’re following a keto diet when they’re really just consuming a low-carbohydrate diet,” says Patti Urbanski, MEd, RD, CDE, a certified diabetes educator with St. Luke’s Hospital in Duluth, Minnesota. “So one person’s ‘keto diet’ may look very different than another’s.”
Earlier in this article, I briefly mentioned how consuming too much sugar can impair brain function and cause plaque build up in the brain. Many studies on Alzheimer’s disease patients agree with the biochemistry as well. In fact, A group of scientists reviewed the literature and concluded that “high carbohydrate intake worsens cognitive performance and behavior in patients with Alzheimer’s disease.” This means that eating more carbohydrates cause more problems in the brain. Will the opposite (eating fewer carbs) improve brain function?

.. 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.


Considering these risks, people who have kidney damage (including those with type 2 diabetes), plus individuals with or at risk for heart disease, and pregnant or breastfeeding women, shouldn’t try the keto diet. Also, people with type 1 diabetes shouldn’t follow the plan because of the risk for hypoglycemia (low blood sugar), and anyone who has had their gallbladder removed should avoid it because the diet is so high in fat.
The ketogenic diet is a high-fat, very-low-carb diet plan. The goal of the diet is to reach a “ketosis” state. The more restrictive you are on your carbohydrates (less than 15g per day), the faster you will enter ketosis. Once in this state, rapid weight loss begins. Research does indicate that the ketogenic diet is most effective in weight loss by reducing visceral (body) fat.
This is a helpful article. But there are some inaccurate things too. I have type two diabetes and use a keto genie diet to lose weight (45# so far). I was able to get my cholesterol down, Triggs down, and my A1C to 6! I went off and followed a Mediterranean diet for a year. I gained back 15# and my diabetes got worse. So I am back on keto. I am using a closer to Mediterranean keto both then and now.
The relation between a high fat diet and cancer is not conclusive. Recent epidemiological studies (17,58–60) could not explain a specific causal relationship between dietary fat and cancer. It has been found that altered energy metabolism and substrate requirements of tumour cells provide a target for selective antineoplastic therapy. The supply of substrates for tumour energy metabolism can be reduced by dietary manipulation (eg, ketogenic diet) or by pharmacological means at the cellular level (eg, inhibitors of glycolysis or oxidative phosphorylation). Both of these techniques are nontoxic methods for controlling tumour growth in vivo (61). Sugar consumption is positively associated with cancer in humans and test animals (58–61). This observation is quite logical because tumours are known to be enormous sugar absorbers. It has also been found that the risk of breast cancer decreases with increases in total fat intake (16). Further studies on the role of a ketogenic diet in antineoplastic therapy are in progress in our laboratory.
Keto-adaption is a state, achieved through significant reduction of carbohydrate intake (typically to less than 50 grams per day), where the body changes from relying on glycogen as its main source of energy to relying on fat.  Specifically, the brain shifts from being primarily dependent on glucose, to being primarily dependent on beta-hydroxybutyrate.  This has nothing to do with what a diabetic patient is experiencing in DKA, but does illustrate how poorly informed and quick to react the medical community is.   DKA and nutritional ketosis (or keto-adaptation) have as much in common as a house fire and a fireplace.
Of the 28 participants enrolled in the study, 21 completed the 16 weeks of follow-up. Reasons for discontinuing the study included unable to adhere to study meetings and unable to adhere to the diet; no participant reported discontinuing as a result of adverse effects associated with the intervention. All but one of the 21 participants were men; 62% (n = 13) were Caucasian, 38% (n = 8) were African-American (Table ​(Table1).1). The mean age was 56.0 ± 7.9 years.
It’s not a good idea to include a lot of dairy in a ketogenic diet because the protein in dairy can deactivate Sirtuin, the anti-aging pathway, and create an insulin spike. While butter and ghee (from quality pastured sources) generally don’t cause this effect, high-fat cheeses and heavy creams do. In addition, dairy products can be inflammatory for many people.

2 days from grains my stomach bloat was gone and I knew at that point everything this article and American diet was a lie. I’ve been on keto for over 16 months. Down 50lbs. In 6 months. I am ripped. Haven’t lost any muscle mass. I eat greens protein and healthy fat. I whole juice to get macros and yes I add watermelon or berries fo palatability purposes. I still eat carbs just healthy choices. I’ve become carb tolerant.. your liver will produce all glucose without ever eating 1 carb. This is biased and poor representation of keto lifestyle. When your starving and no carbs to choke keto will still thrive on either or fuel.
Sleep improvements are a bit more of a mystery. Studies have shown that ketogenic dieting improves sleep by decreasing REM and increasing slow-wave sleep patterns. While the exact mechanism is unclear, it likely is related to the complex biochemical shifts involving the brain’s use of ketones for energy combined with other body tissues directly burning fat.
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.

Additionally, you may find it difficult to eat adequate calories on a daily basis because fat is so filling. Some people even opt to fast for several hours each day. While this may help with weight loss, your body needs those calories for proper maintenance. Without them, it may turn to burning muscle for energy, and that can accelerate muscle loss.
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.

Also, as I believe is mentioned, this diet has been around for along time and was the only way to treat diabetes. And some people did die. However, people still end up dead from t2d even after all the diet advice from educators and with all that pharmacy has to offer. An industry which gains nothing if people just choose to eat less. But has lots to gain if we just keep taking the tablets.
People this is crap. There is no Keto drink that will get you into ketosis within an hour. The main factor of eating Keto is to eat WHOLE UNPROCESSED foods. Which definitely does not include a magic fix drink. People that eat Vegan, Paleo and Keto have one core thing in common… to try their best to eat whole, natural, unrefined and unprocessed foods. We may not agree with what we eat per say, but I believe that we can all agree that drinking a “magic drink” or taking a “magic pill” to get us into any state is absolutely ridiculous. It’s exponentially offensive to those of us that are trying to educate and help others and especially offensive to those that have lived and succeeded living a whole lifestyle. Travis, get off this feed. Your doing nothing but trying to capitalize on people’s vulnerability.
To ensure you are getting enough potassium, include avocados and leafy greens like spinach in your daily diet. Sprinkle some unrefined salt on every meal and in your water to replenish your sodium levels as well. Some ketogenic dieters suggest getting at least 5 to 7 grams of salt per day (one teaspoon to a teaspoon and a half per day) during your first week on the ketogenic diet.

Adding salt to food might be new to you, since most people are used to being told to limit salt intake. However, when you’re eating a ketogenic diet of less than 60 carbohydrates each day, you’ll need to make up for this loss of salt. That being said, those with high blood pressure who take medication should check with their doctors before making a change.


Thankfully, a few keto variations have been developed that are a little more flexible, and easier to stick with long-term. The traditional or standard ketogenic diet puts your body into ketosis: In this metabolic state, you burn fat (rather than carbs) as your primary fuel source, and that promotes fat loss. On a modified keto diet, your body will go in an out of ketosis, but still shed weight and body fat. Check out the guide below to see how each of the four keto diet types work. 
Here’s the thing, the Keto diet can be executed in many different ways.  The only requirement for achieving ketosis is to restrict carbs and limit protein so that the bodies glycogen reserves are depleted to the point that ketosis kicks in.  If you do that by eating hot dogs and margarine then I agree with this claim, you are on a dangerous nutrient-deficient diet.  However, if one chooses to achieve ketosis by eating fatty cuts of quality meat, dairy, nuts and plenty green leaves and fibrous vegetables-they are on a nutrient dense, complete diet.

Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose.

If you’re a generally healthy adult who’s looking for a new way to eat, it’s probably fine for you to try the diet. Just think carefully about your motives, intentions, and long-term plans. Any diet you follow for a short period of time might garner some initial results, but if you’re not intentional about switching to a sustainable, long-term healthy eating pattern, the benefits you see while going keto are likely to be short-lived. Be honest with yourself about whether or not you have the self-control and desire to follow such a restrictive eating pattern. If you don’t, that’s OK. The best diets are those you can legitimately sustain for a lifetime. Restriction isn’t always the best answer.

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.
Thank you Dr Jockers! I recently came across your website and i absolutely love what you do. I am an advanced practice nurse and just started a part time keto coaching practice.I am already amazed by the changes i see in my clients. Do you have by chance a training program for keto coaches. If not, is there one out there that you recommend? Thank you in advance.
One of the keto side effects people may complain about is keto breath.  Although this is not quite related to the three major causes we’ve discussed so far, keto breath is something that many people experience in the early stages of keto adaptation. When you begin producing ketones, you produce them in several different forms. The ketone that is released through the breath is acetone and is responsible for the keto breath that some people experience.

By now, most of us have heard about the ketogenic diet. Whether it's because of the benefits of eating high-fat and low-carb, or because you can eat cheese all day long, it's officially become one of the hottest diets of the year. It may not be easy to cut out all the carbs, but emerging research suggests that eating fat can actually help burn fat. So, for anyone trying to lose weight, you may find it worth the carb cut. Beyond weight loss, recent research has found some other serious health benefits of keto that may impact your life later on. Let's take a look at what the research has to say.
Once the body gets used to manufacturing ketones as the main energy substrate, the body actually has more energy than it previously had, and you won't have to be fighting through all those low-blood-sugar crashes your high-carb meals previously gave you. Additionally, hydration should be an area of high priority, especially before, during, and after exercise.
Celiac disease is another condition with a very well established link to psychiatric and neurologic conditions. It is estimated that one to two of every 100 people has celiac disease, an immune disorder in which the ingestion of gluten in wheat, rye and barley destroys the lining of the small intestine, leading to a wide array of health problems. Another six out of every 100 people may have non-celiac gluten sensitivity, which while not having evidence of damage to the lining of their small intestine nevertheless can experience a wide range of health issues, including mental health issues.
The understanding of “What is a Keto Diet” has become blurred thanks to the proliferation of Keto Diet “experts”. Many of these “experts” recommend several variants of Keto Diet and lifestyles which they claim can be modified to any walk of life. However, in most instances what they are actually recommending are Low-Carb lifestyle programs. These are neither weight loss programs, nor Ketogenic. With that said, there’s nothing wrong with adopting a Low-Carb lifestyle, but if your goal is weight loss, then changing your eating lifestyle should come after you’ve achieved your weight loss goals.
Oh how I miss you, delicious high-fat smoothie 😫 🌿🌱🍃Day 15 on carnivore and I am feeling quite amazing though! 🥩 ~ UPDATE: I don’t have “recipes” I make food to taste but if I recall this was something like: -a handful of blueberries -half a carton of coconut milk -macadamia nuts -a couple glugs of @perfectketones MCT oil -some chunks of cacao butter -some chunks of coconut butter -half avocado -spinach, kale, cabbage -some ice and maybe a little water to get consistency right MUST use a badass blender (I use blendtec) -toppings: you can see them. Put what you like to eat on top.
For those who want to follow a ketogenic-type diet, Dr. Reynolds says it is important to first talk to your doctor and to discuss your goals so you can be sure that this approach is suitable for you given your medical and health history. Ongoing monitoring is needed if you do decide to adopt this very carb approach to eating. Seeing your doctor regularly is important to make sure that your blood pressure, lipids, blood sugar, mood, and medications are within normal ranges as you lose weight. Adjustments are likely going to be necessary from time to time.

Glucose is stored in your liver and released as needed for energy. However, after carb intake has been extremely low for one to two days, these glucose stores become depleted. Your liver can make some glucose from amino acids in the protein you eat via a process known as gluconeogenesis, but not nearly enough to meet the needs of your brain, which requires a constant fuel supply.
