“The human digestive tract is simply not well designed for digesting grains. The proteins in grain, especially the gluten, are very difficult to digest, even if you don’t have apparent gluten problems. Too much grain, especially of the highly refined kind, is behind many of the cases of food allergies, irritable bowel, chronic indigestion, and yeast overgrowth that I see every day.”

I know it is hard when you have been taught something, and believed it, and taught it to others…only to be shown that what you have been taught is not the end all be all that you were led to believe. It sucks. But, you can choose to ignore the truth, and continue to follow the incorrect path. Or, you can look at the facts, and realize that what you have been taught is not the truth…and you can take a new path, which will lead many to wonderful new lives.
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 >
I have T2D and IBS and my blood sugar readings were degrading. I was going to have to take a second daily dose of Metformin and the first one already played havoc with the IBS. I started a low-carb diet because my T1D husband had been inspired by a podcast by Sam Harris with scientist Gary Taubes, author Why We Get Fat, Good Calories, Bad Calories and the Case Against Sugar, and started dumping the majority of his carbs a month previous. He had cut his insulin use literally in half and lost 15 pounds. He was feeling better and visibly had more energy. I was resistant to the diet and even the idea of it. I have been on Atkins and Sugar Busters and while I did fine on Sugar Busters back in the day, Atkins was too fat-based and that was the opposite of how I had been raised to think about dieting. I knew that the Diabetic diet given to me by the Diabetic Educator had never been enough and I get carby binge cravings even though it offers plenty of carbs and calories. I also knew that it’s a cycle for me-eat more carbs, want more carbs, and never really feel satisfied. On top of that, when my stomach hurts I seek carbs, and it hurts quite often. I did Weight Watchers and the Diabetic diets because they let me “cheat” and have my carbs while dieting. To be fair, just the act of tracking my food improved my outcome on either. But I got mad at WW when they upped the points for carbs on their system and made it so I couldn’t eat cake for lunch if I wanted to. Not that I made a practice of it, but it was principle of the thing. Long story short, I was pretty doubtful that I would be very successful on Atkins or Keto. To humor my husband I began a low-carb diet that started out as Atkins 20 or Keto and has morphed to more of an Atkins 30-40 for my personal comfort while using Keto, Atkins, and Paleo recipes and ultimately cutting all gluten. That means 30-40 net carbs per day, rather than per meal and a lot of natural non-processed foods. The first week was quite terrible. But even through the Keto Flu I recognized that my IBS symptoms felt better. I started to suspect that if I felt that bad just from quitting carbs that maybe there was more to the idea of sugar addiction than I wanted to believe. I’m six weeks in now and I’m losing a steady pound a week plus my sugars have dropped radically. A pound a week might not sound like much but it’s more than I’ve lost in 10 years. I have PCOS and insulin resistance so I’ve had a fasting blood sugar that ranged from 109-113 since my early twenties. It was flying high around 160-170 before the diet, now I’m reading between 119-139. Even more than that, my IBS symptoms stabilized. I’ve been tracking all my food using the free Atkins meal tracker so I started trying to narrow the foods that caused flare ups. I’m lactose intolerant but I knew that and used lactose free products or Lactaid for the cream based dishes. I had my gall bladder removed and so have always put down my symptoms to an inability to process dairy and fats. Big surprise to find that a higher fat, higher dairy diet was making my symptoms disappear. Gluten is the only common factor so far. Celiac? Just a food sensitivity? I don’t know, but that will be the next investigation. It is an investigation that I would never have thought to start on the Diabetic diet. Like the author, I’m very fond of cake and carbs. Luckily there are low-carb, no-gluten recipes for muffins and cakes. They aren’t exactly the same and some are definitely better than others, but they are out there. Plus, there is nothing wrong with having true birthday cake once a year if that is really what you need and if you don’t have a reason to avoid it, like binge symptoms or IBS flare ups. My husband let himself have a piece of cheesecake the other day and felt physically awful for two day after, plus he had to use a lot of insulin to counter the spike. It’s a pretty good deterrent. Just a side note but I had other symptoms of inflammation as well. My ankles were swelling to golf ball size and painful, it was difficult for me to stand and walk comfortably when this happened. While they haven’t stopped completely, the discomfort has gone way down as has the swelling and frequency. What’s my point? I’m not a salesman for a particular diet. Everyone is different and some people might respond very well to Keto and/or Atkins while others may not need anything that extreme. I’m not knocking the Diabetic diet. My dad lost 150 pounds 38 years ago on a very low calorie/low carb Diabetic diet that gradually increased and he has kept the weight off all this time and kept his blood sugar steady with medication, but has not had to go to insulin even at age 84. Also, he was a smoker, a diabetic, had hemochromatosis and was over 300 pounds with an apple body shape. He has had some fall out from this-he didn’t stop the smoking until a heart attack 20 years ago and that didn’t help. But he has made it to 84 and when he walked into his doctor’s office 40 years ago I’m guessing the doctor wouldn’t have put any money on that survival rate. Unfortunately, it looks like I need the lower carb version and will continue to need it to manage my symptoms. I didn’t want it, that’s for sure. But Diabetics are locked in a death struggle with Diabetes and it won’t give up just because we are tired or want our sugar. So for me, it has to be Very Low Carb for Life. Others may find they need this too and discouraging them from trying it is not doing them any favors. Hopefully I will continue to find this sustainable. I just need to keep reminding myself that I am more fond of my feet and my vision than my birthday cake.

Keto cycling is a way to cycle in and out of ketosis while enjoying a more balanced diet on your "days off." One keto cycling approach includes five days of traditional keto diet and two non-keto days per week. Some people choose to save their off days for special occasions holidays, birthdays, and vacations. For best results, eat wholesome carbohydrate-rich foods on your off days, including fruits, starchy veggies, dairy products, and whole grains (rather than added sugars or highly-processed fare).
Type 1 diabetes causes the same blood sugar control issues as type 2 diabetes, but in an entirely different way. Type 1 diabetics cannot produce enough insulin or any insulin at all, which requires them to have insulin administered exogenously. On top of that, the perfect diet will not be able to reverse this disease as the ketogenic diet can for type 2 diabetes.
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.
The high-fat, very low-carb keto diet lets you enjoy lots of avocado, butter, bacon and cream—but requires cutting way back on added sugars, most processed foods, sweets, grains, and starchy veggies (whew). The eating plan is mega-popular among Hollywood A-listers (including Halle Berry, Megan Fox, and Gwyneth Paltrow); but if you don’t have a private chef who can futz with fats to make delicious meals and snacks, the carb-restricted lifestyle can be extremely challenging to follow. 
Unless you’ve already been eating a paleo or primal diet and are somewhat keto-adapted (burning ketones for fuel), it is a good idea “reset” the body in order to regain the metabolic flexibility to go into ketosis or even stay in ketosis despite eating some carbohydrates. Intermittent fasting is one efficient way to do this. During a water fast, ketosis can occur in days instead of weeks or months and often sustains for a while after the fast.
I’m following the ketogenic diet and I find it very easy, pleasant and varied. I can even say that my diet today is more varied than the previous one. I do not intend to leave this diet and I cannot really see why. My initial focus was not to lose weight, I’ve always been lean, but to feel better, well disposed. And I got it! I am very pleased, I have read a lot about it (including scientific literature) and I have influenced other people who need to lose weight or improve some aspects of their health. But from the beginning I went on my own way, without the help of a nutritionist because I did not want to suffer the influence of others’ ideas.
To see where you stand on the ketosis scale, you can test your ketone levels with a blood meter or with urine strips, the latter of which works similar to a pregnancy test and generally costs less than a dime a piece. Recent research shared in The American Journal of Clinical Nutrition, however, found that breath monitors (typically $200 to $300) provide the most accurate readings. Dozens of meters of all three formats are currently available on Amazon.
Related to this research, some serious attention has been given to ketogenic dieting and Alzheimers Disease. Scientists have discovered increased cognition and enhanced memory in adults with impairments in these areas, and a growing body of research shows improvement at all stages of dementia. Ketosis has been shown to be effective against Parkinson’s disease as well.
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 the same with a keto way of eating: there is a ton of research and studies out there, and we KNOW that it works. Sure, more studies will come, and the new information will help us refine it, and we will learn how it specifically affects certain individuals in different ways…but the truth about the basics of it are all there, in the open, for all to see.
Several comprehensive studies and meta-analyses have demonstrated that after a few months or even a year of a low carb diet versus a moderate/high carb diet, there are no significant differences in the amount of weight lost (2,3,4,5).  I will say, however, most of these diets are NOT keto and are simply lower carb (i.e. 20%).  Also, long-term effects (beyond 1 year) are not often studied due to budgetary constraints, so interpret results as you wish.

When the ketogenic diet is followed in a healthy manner (which considers avocados a healthy fat instead of pork rinds), there is some evidence that the diet can improve heart health by reducing cholesterol. One study found that HDL ("good") cholesterol levels significantly increased in those following the keto diet. The LDL ("bad") cholesterol went down significantly.
The keto diet involves getting up to 80 percent of daily calories from sources of healthy fat, a significant change for most of her patients who were accustomed to running on carbs, caffeine and sugar for energy. It became clear that something else had to be adjusted in order to prevent the side effects associated with the keto diet. This is when she came up with the idea to focus on restoring alkalinity first and foremost.
The struggle as a prescriber is that you have to follow the “standard of care,” lest you open yourself up to a lawsuit. So I talk to my patents about what “the” recommendations are, and then I talk to them bout what the evidence says and what my experience says. Plain and simple, patient’s trust the government’s recommendations and can’t wrap their head around the idea of not eating carbs because they have learned their entire lives that the body “needs” carbs to survive.
Then, a friend of mind told me about this supplement. She said that she had used it in the past and it had helped her greatly. Promising myself that this is the last supplement I am going to try, I placed an order for this product. When it arrived, I was pretty satisfied with the packaging. I read the using instructions and followed them for a week straight.

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."

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.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).

In order to reach true ketosis, you need to switch to a different metabolic state where you use body fat as a fuel source instead of glucose. Running out of glucose means nutritionally starving as far as your body is concerned, and ketosis is the response. While using excess adipose tissue is generally seen as a good thing, it doesn’t happen in a vacuum. In addition to breaking down fat cells, your body also breaks down muscle in the form of protein to create glucose. As a long-term side effect, this means that the keto diet eventually decreases lean body mass, which can make it harder to lose weight once the diet has ended.

“Studies have shown that the ability to stick to a diet is more important for long-term success than the type of diet that’s followed,” says Yawitz. “Keto is incredibly restrictive and is particularly tough for those who have frequent social engagements or are prone to carb cravings.” The Mediterranean diet allows you to eat carbs, like as many fruits and veggies as you want, along with whole grains. Not to mention, the Mediterranean diet has been linked to a number of other health benefits, including a lower risk of Alzheimer’s and Parkinson’s disease, certain types of cancer, and heart disease, according to the Mayo Clinic.
Can’t you take ketone supplements? No. While it is possible to elevate ketones by taking them, “without the low-carb stimulus, there is no net increase in ketone production, no decrease in insulin, and no net increase in fat oxidation,” says Volek. Don’t trust trainers or “body hackers” who say you can induce ketosis quickly without changing your diet.
I know a few people who struggle with keeping on the low carb diet and staying in ketosis. They introduced me to a exogenous drink called keto/os that is a natural energy drink that contains ketones. It gets you into ketosis within an hour!!! This can be tested in the blood and they showed me the results and it works!!! Not only that but it dropped their blood sugars as well. I am now on the product myself for other reasons but just thought I would share it. Let me know if you want more info.

From baseline to week 16, the mean body weight decreased significantly from 131.4 ± 18.3 kg to 122.7 ± 18.9 kg, BMI decreased from 42.2 ± 5.8 kg/m2 to 39.4 ± 6.0 kg/m2, and waist circumference from 130.0 ± 10.5 cm to 123.3 ± 11.3 cm (Table ​(Table3).3). The percent change in body weight was -6.6%. The mean percent body fat decreased from 40.4 ± 5.8% to 37.0 ± 6.0%. Systolic and diastolic blood pressures did not change significantly over the 16 weeks. The mean heart rate decreased from 81.2 ± 12.9 beats per minute to 74.6 ± 14.0 beats per minute (p = 0.01).


There are people who say that keto helps your athletic performance, and those who say it hurts it. "The literature is mixed on how an ultra low-carbohydrate diet like the keto diet affects athletic performance," says Grant Cox, C.S.C.S., head coach at Iron Tribe Fitness. But one thing is pretty clear: "A lot of it points to consistent decreases when athletes are looking for maximal power output (in weightlifting, vertical jumps, sprinting, etc.). Along the same lines, you'd be hard-pressed to put on weight and strength on such a low carbohydrate diet," he says.
“Tremendous Results”….guess that’s why the diabetes nationwide gets worse every year, because of the stellar advice your kind is giving out. I’ve been on the virta clinic for two months and already went off insulin, Janumet and Jardiance, which I’ve been on for 10 years, with blood sugars between 80 and 150. The advice you give makes people get sick slower. The ketogenic approach deals with the real issue, carbohydrate intolerance. If you are lactose intolerant you stop ingesting lactose. Type two diabetes is simply carbohydrate intolerance. Stop eating the carbs and the symptoms go away. I think you meet to cite some of the other research out there I’ve read in other books and the work the Virta Clinic has done. In my opinion you’ve cherry picked data to suit your preconceived beliefs.
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.
Controlling your blood sugar levels helps you control your cravings, Dr. Burrows says. “When we are not on a sugar roller coaster from processed carbohydrates, most people make better food choices because they are not looking for their next hit of food,” she says. You may also find you’re able to go longer periods without eating, he says. Intermittent fasting is a common practice among dieters who’ve been eating keto for a while. Learn how one woman totally kicked her sugar habit by trying the keto diet.
Cyrus Khambatta earned a PhD in Nutritional Biochemistry from UC Berkeley after being diagnosed with type 1 diabetes in his senior year of college at Stanford University in 2002. He is an internationally recognized nutrition and fitness coach for people living with type 1, type 1.5, prediabetes and type 2 diabetes, and has helped hundreds of people around the world achieve exceptional insulin sensitivity by adopting low-fat, plant-based whole foods nutrition.
Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese.
The benefits of a ketogenic diet have been well documented for those living with Type 2 diabetes. Not only does the diet help manage blood sugar but it promotes weight loss as well. The results for those living with Type 1 are less conclusive. Many studies tend to address low carb diets like paleo and Atkins, which focus more on types of low carb food to eat, unlike a keto diet, which pays close attention to macronutrients and staying in ketosis. There seem to be fewer studies exploring the latter, but there is observational information that seems to indicate the diet offers a way to manage A1C levels and glycemic control. Many people with diabetes who abide by the keto diet have found that they significantly reduce their use of insulin.
Although various short-term studies examining the effect of a ketogenic diet in reducing the weight of obese patients have been carried out (10), its long-term effects in obese subjects are not known (15). Therefore, the purpose of the present study was to investigate the long-term effects of a ketogenic diet on obesity and obesity-associated risk factors in a large population of obese patients.
On a “strict” (standard) keto diet, fats typically provides about 70 percent to 80 percent of total daily calories, protein about 15 percent to 20 percent, and carbohydrates just around 5 percent. However, a more “moderate” approach to the keto diet is also a good option for many people that can allow for an easier transition into very low-carb eating and more flexibility (more on these types of plans below).
Although many people find that their energy and stamina improve on a keto lifestyle, trying to do too much in the early stages can worsen keto flu symptoms. Well-known ketogenic researcher Dr. Steve Phinney has conducted studies in endurance athletes as well as obese individuals demonstrating that physical performance decreases during the first week of very-low-carb eating. Fortunately, his research also shows that by week 4, people typically perform better than before they started keto.

The problem is the SAD diet (Standard American Diet) and eat less move more advice. Tell that to a baby boomer with a hi bmi. Keto if done properly allows over weight people a way to lose weight without having to do hours in a gym. It is recomended to do a 15 minute walk now and then to keep a level of fitness. The weight is coming off even if one doesnt excercise. No sugar highs and lows, no cravings of carbs. Easier to do intermittent fasting to break plateus. Having the control over food and not being a slave to it. Reduction in sugar levels. The chance of autophahy. No brain fog. The chance to reverse type 2 diabetes. We have an obesity problem world wide. Yes you do have bad breath. Yes you can get constipated. Shall I stop because of a couple of negatives. Both negatives are treatable. The keto wave is coming. Empowering people to take control of thier own bodies by controlling thier insulin levels by keeping all sugar derivied products to a low level. The food companies drug companies are worried.

However, the lower calorie Keto Diet also features a reduction in fats as well. In doing so, this Keto Diet accelerates fat loss and is better suited for losing weight. After all, between 2 Ketogenic Diet types, with one having a higher caloric intake than the second, which do you think would be the better choice for weight loss? Obviously the lower calorie diet. By reducing fats, your caloric intake is also reduced. As a result, the dieter’s weight loss will occur more rapidly.
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...
So rather than giving one-size-fits-all dietary advice or weaponizing the word “balanced” it might be better if the medical community suggested that there are Individual differences that need to be considered. This might also help those lay folk who have had success with one dietary lifestyle or another also realize that what’s valid for them may not be good advice for others.
Vegan ketogenic diet or vegetarian diet: Yes, both are possible. Instead of animal products, plenty of low-carb, nutrient-dense vegan and/or vegetarian foods are included. Nuts, seeds, low-carb fruits and veggies, leafy greens, healthy fats and fermented foods are all excellent choices on a plant-based keto diet. There’s also a similar plan called ketotarian, which combines keto with vegetarian, vegan and/or pescatarian diets for supposedly greater health benefits.
Considered a symptom of the keto flu, your breath on this diet often smells fruity at first. This is because acetone is a by-product of ketosis and is eliminated mostly through the lungs and the breath, according to a study in the journal International Journal of Environmental Research and Public Health in February 2014. Acetone is a type of ketone known for having a fruity aroma in smaller concentrations. “It’s hard to say exactly how long it will last as it depends on the person, but it’s common for someone to experience this side effect for a few weeks,” says Asche.
Participants completed take-home food records (4 consecutive days, including a weekend) collected at baseline and at weeks 2, 8, and 16 during the study. Participants were given handouts with examples of how to complete the records. A registered dietician analyzed the food records using a nutrition software program (Food Processor SQL, ESHA Research, Inc., Salem, OR).
Meat is the only nutritionally complete food.  Animal foods (particularly when organ meats are included) contain all of the protein, fat, vitamins and minerals that humans need to function. They contain absolutely everything we need in just the right proportions. That makes sense, because for most of human history, these would have been the only foods available just about everywhere on the planet in all seasons.
Adherence to a keto diet food list isn’t always great, though. A review published in January 2015 in the Journal of Clinical Neurology found that only 45 percent of participants were able to follow the approach as prescribed. “The poor compliance was attributed to side effects, social isolation, and cravings,” says Yawitz. And some people in the study “reported the diet simply wasn’t helping them lose weight,” she adds. Brissette agrees with this line of thinking. “In my opinion, the keto diet isn't sustainable and takes the joy and fun out of eating,” she says.
Studies since shown that the accumulation of fat droplets, and not carbohydrate stores in the liver and muscle cells, contributes to insulin resistance and type 2 diabetes. These droplets result from raising levels of saturated animal fats in the blood, like those found in chicken, beef, cheese, dairy and fish. One hit of saturated animal fat can start causing insulin resistance, inhibiting glucose uptake after just 160 minutes (11).
Identifying not-so-obvious acidic foods. There are a few acidic veggies (like Brussels sprouts), as well as alcohol (sorry!), coffee, and most dairy that are acidic and must be avoided. That doesn’t mean you’ll never eat them again. I can’t imagine life without wine and chocolate and brussel sprouts! Just be aware that as your body shifts into alkaline mode, they will be off limits temporarily.
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.
Earlier this year Seattle family doctor Dr. Ted Naiman, who has been helping patients with low-carb or ketogenic diets for 20 years, described how his own obsessive compulsive disorder was resolved almost instantly — never returning — on a low-carb high-fat diet. Naiman over the years has seen dramatic mental health improvements in his patients who adopt low carb ketogenic diet. “Definitely bipolar, depression, anxiety, OCD, are all much, much better on a low-carb diet,” he says.
Keto diets are high in healthy fats and protein also tend to be very filling, which can help reduce overeating of empty calories, sweets and junk foods. (4) For most people eating a healthy low-carb diet, it’s easy to consume an appropriate amount of calories, but not too many, since things like sugary drinks, cookies, bread, cereals, ice cream or other desserts and snack bars are off-limits.

There is a reason why we store hundreds of thousands of calories in the form of fat in our body and only about 2000 calories in the form of glucose (with only a small amount of this useable by the brain). The reason is simple - The body prefers fat as its fuel source. Mark Sisson explains this in his article ‘A metabolic Paradigm Shift, or Why Fat is the Preferred Fuel for Human Consumption’.
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.)

Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.


Following a ketogenic diet puts your body into a state of “ketosis,” which is a metabolic state that occurs when most of the body’s energy comes from ketone bodies in the blood, rather than from glucose from carbohydrate foods (like grains, all sources of sugar or fruit, for example). This is in contrast to a glycolytic state, where blood glucose (sugar) provides most of the body’s fuel (or energy).
A ketogenic diet – due to its extremely low carb intake – can help address insulin resistance and in turn help with suffers of PCOS. In fact, a pilot study has concluded that a ketogenic diet led to a significant improvement in body weight, fasting insulin, testosterone markets and LH/FSH ratio in woman with PCOS. Two woman even became pregnant during the study.
