The purpose of this study was to evaluate the effects of a low-carbohydrate, ketogenic diet (LCKD) in overweight and obese patients with type 2 diabetes over 16 weeks. Specifically, we wanted to learn the diet's effects on glycemia and diabetes medication use in outpatients who prepared (or bought) their own meals. In a previous article, we reported the results observed in 7 individuals ; this report includes data from those 7 individuals along with data from additional participants enrolled subsequently.
Remember the low-fat diet craze? Back in the 1990s, we were told that swapping regular cookies and chips for those labeled "low fat" would be the ticket to easy weight loss and better health. Today, it's the opposite—a low-carb, high-fat eating plan called the ketogenic diet, or keto diet for short, is getting all the buzz. Celebrities like Halle Berry, Kim Kardashian, and Megan Fox are fans; more than 7 million Instagram posts have been tagged #keto; and upwards of 1 million people search "keto diet" on Google every month.
Louella you are absolutely wrong. It’s actually funny to me that this dietitian talks about the keto diet to such an extent but neither you nor her ever mention Gluconeogenesis. Yes your brain has specific areas that can only use glucose, but the human body is a wonderful thing and can use a few different substrates to synthesize glucose without you ever having to eat it yourself. Look up Gluconeogenesis. Your body has the ability to convert the amino acids you find in protein into usable glucose for your brain. The fact that you don’t know this shows me how uneducated you are about the ketogenic diet in general. Perhaps you should read up on the subject before you start trying to sound like a scientist who clearly has no idea what she is talking about. Thanks.
On the keto diet, your body begins to shed fat, water and glycogen, and as this happens you lose key electrolytes, such as sodium, potassium and magnesium. When you're running low on these electrolytes, you might experience headaches or extreme fatigue. These losses are most pronounced during the first few weeks after you enter ketosis, so if you're going to start the keto diet it's best to plan ahead to make sure you get healthy amounts of these electrolytes — and other vitamins and minerals — either through supplements or a thoughtfully-designed meal plan.
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.
Hello everyone. I was diagnosed as a diabetic in 2010. I followed the ADA diet while taking metformin and lnsulin and could never get by glucose readings below 135. Most mornings it was at 175 or higher. In mid 2017 I had to find a new doctor. I ran out of meds in Semtember of that year but could not find a doctor due to not accepting new patients and or my health insurance. I broke my foot at work on the last workday in December. Was instructed to stay off foot for 6 to 9 months . In the mean time I finally got to see my new family practitioner on March 28 2018. Represcribed meds and ordered blood work. A1c was ar 14.1. With my new glucose meter my readings were 375. Due to basically being bedridden while my foot heals I was concerned about diabetic complications an weight gain as I was already overweight. After doing research online I learned about the keto diet. I began the diet on 3/29 /2018 along with intermittent fasting. I weighed 265#. As of 4/26/2008 I am at 245#. My glucose readings have been on average 73 to 98 and a couple of times 111. I stopped all my medication about a week ago just to see if they would increase. They have not so far and I check 4 times daily. I sleep better and do not crave sweets. I feel full . The first two weeks were tough but now I can go 2-3 days without being hungry. I am looking forward to the results of my next blood test in June. This diet fits my circumstances and I do plan on to exercise when I am able to. I want to reach my weight to height ratio also. When I achieve this goal I may tweak my diet at that time but for right now that is what is working for me. I may never be able to eat some of the things I used to but considering the complications of diabetes it is one hell of incentive for willpower to stay on the diet.I will repost again after my next blood test or if there are any significant changes.
Although the exact role of the keto diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, it works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a low carbohydrate, high-fat diet in neurology is promising.
In the brain, there are some parts that can only take glucose to burn for fuel, which is usually derived from carbohydrates. However, when the body is on a ketogenic diet, the body will enter ketosis, which is a process that produces proteins called ketones from fatty acids in the liver. The brain can surprisingly also take in these special ketones to function. Past studies have shown that children affected with epilepsy who are on this diet have a 50% lower chance of reducing seizures. 16% of that group have also shown to be seizure free. This diet is for individuals with Parkinson’s disease and Alzheimer’s to see if ketogenic diets can also help.
As far as the Ketogenic Diet is concerned, I think I am going to have to make a full about-face. As you said, for some people like yourself, you were unable to eat in moderation and feel it is due to your genetic makeup. This is probably true…to add insult to injury, in addition to genetics, it could also be an inflammatory process going on due to the sugary drinks and processed foods we are eating causing obesity and a host of other issues.
Ketosis has a protein-sparing effect, assuming that you are consuming adequate quantities of protein and calories—0.7 grams per pound of body weight per day—in the first place. Once in ketosis, the body actually prefers ketones to glucose. Since the body has copious quantities of fat, this means there is no need to oxidize protein to generate glucose through gluconeogenesis.
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.
Having said that, there are also studies suggesting that long term carbohydrate restriction diets (aka. the keto diet) may result in fast short term weight loss but people gain it all back in the long term. An RCT put 63 individuals on a low-fat diet or a low carb diet, and the study found the low carb dieters lost more weight compared to the low fat group by month 3 and 6, but that the weight loss evened out by month 12. This was confirmed by a Meta-analysis which found that while low-carbers lost more weight than low-fat dieters but the differences disappeared by the one year mark.
Thank you so much for this article! My husband and I have been following keto for a little over a month now and we love it! I did a lot of research before starting, and am still doing lots of research because I like to be armed with the best information I can have when friends question my choices. Just yesterday I had a friend tell me that our brains need carbs to function (more than what we get from veggies). I hadn’t heard that before so I didn’t know what to answer. Thanks to your article now I know, and I have lots more answers in case more points come up. 😉
Others consider the keto diet a short-term solution for weight loss. Tyler Drew, a 34-year-old real estate broker from Los Angeles, first read about the diet on Reddit and used it to lose 45 pounds in six months before returning to a traditional diet. While on the keto diet, Drew’s cholesterol levels improved, even though a typical day of eating involved bacon at both breakfast and dinner.
As ketosis begins, your body will start dumping its stores of glycogen, a substance in your fat and muscles that carries excess weight. This will increase how often you urinate and can lead to an inevitable loss of electrolytes, Dr. Rahnama says. Electrolytes are essential to cardiac function and normal heart beating. “The loss of electrolytes, such as sodium, magnesium, and potassium will put the dieter at risk of a cardiac arrhythmia,” Dr. Rahnama adds.
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.
Kidney stones are usually a sign of excess oxalates in the diet and/or Vitamin K2 deficiency. If the kids were eating a no-vegetable diet where were the oxalates coming from? If they were eating the vegetables why the constipation and dysbiosis? What were they not eating that caused a K2 deficiency? You don’t have to be on a keto diet to have kidney stones as I know only too well.
The Ketogenic Diet is a low carbohydrate diet, consisting initially of less than 20 carbohydrates per day. Not per meal, yes, you heard me correctly, per day. It is not for the faint of heart and yes I am writing from experience. Of course I have tried it! Hasn’t everybody in America at some point who has wanted to lose weight? Does it work you ask? Of course it does! The problem is how long can you keep it up?
I was diagnosed in 2004 with Brittle Type 1 diabetes, peripheral and autonomic neuropathy, and Hypothyroidism. A short time later with Gastroparesis due to the nerve damage from diabetes. Since then, I had followed every guideline and rule that the Endocrinologist and Primary Care Doctors had told me to follow. NOTHING WAS GETTING BETTER. In fact, I was gradually getting worse. So many ups and downs. Extreme highs (250-500 bgl ) to seizures from crashes (drop from 300 to 13 in no time). It was a constant battle with adjustments in insulin intake (and different insulins NPH, R, Novolog, Humalog, Lantus), carb intake, exercise and one contributing factor was the Gastroparesis. Meds were taken for the Gastroparesis but I always had side effects from meds. To my point. I was kicking a dead horse and I told them this. My sister and mom had come across the ketogenic way of eating and it dramatically improved thier lives. Mom was diagnosed way back with Type 2 and within a week or two she was off of her meds completely. I was totally interested. So, I decided to go for it on April 17, 2017. I did go through some rough patches of what they call Keto Flu. It did pass after a couple weeks. I was gaining so much energy like never before as well as mental focus. The even greater aspect of this all was, I had DRAMATICALLY LOWERED MY INSULIN INTAKE TO ALMOST NONE! My Lantus was always being adjusted from 30-40 units daily (and changed from AM to PM to splitting it to half AM, other half PM). I was on a sliding scale of Humalog or Novolog. From 4-6 units per meal and then there were the corrections throughout my day (some daily totals could be up to 40 UNITS)! Very exciting for me to only take 2 units of Lantus in the AM and daily totals of Humalog/Novolog….1.5-3 units! Other great things I began to notice, neuropathy pains were fading and finally GONE. No more nights up stinging, burning and RLS (restless leg syndrome). So, in my life, there are no questions or hardships on whether I can get off of this way of eating. It’s either do or die. If someone truly wants to have a better life, they can. The sad thing is, doctors and nutritionists aren’t being educated in the real facts. My primary care doctor isn’t willing to help me with all the labs I need nor listen. Always telling me “You need carbohydrates and insulin to live.” All that know me see the dramatic change for the better. I’m doing the Ketogenic way of eating with intermittent fasting for the rest of my life. The alternative IS NOT WORTH a lifetime of illnesses and suffering.

Ketosis: What is ketosis? Ketosis is a metabolic process, and it involves the body burning stored fat instead of glucose. Some people try to induce this with a low-carb diet, which can be healthy. However, ketosis also produces acid, and high levels of this can cause severe complications, especially for people with diabetes. Learn more here. Read now
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.
Otherwise in a nutshell ketosis can be defined as a “metabolic state that happens when you consume a very low carb, moderate protein, high fat diet (or fast for extended periods) that causes your body to switch from using glucose as it’s primary source of fuel, to running off ketones. Ketones themselves are produced when the body burns fat, and they’re primarily used as an alternative fuel source when glucose isn’t available.” (Keto Clarity)
I take thyroxine 150mgs for my underactive thyroid issue. My dose does need to be adjusted regularly. I have gradually put weight on despite eating healthily & generally avoiding fats, because of a raised Cholesterol level. I can’t take Statins either because it causes muscle problem! All in all I am at a loss. I really want to lose my excess weight (28pounds). I have started the keto diet now & it’s a way of eating totally alien to me! I’m eating foods I never eat! I’m only a week in & am having dizzy episodes but am taking the steps to stop these but now I have read that having thyroid issues I should not pursue it. I’m really devastated. Can I get around this?
The crazy thing is it is not hard, if it matters. Sure I can see it being hard for someone who does it to lose weight, then when they get closer to their ideal, they want to have treats, etc. Well, for a type one diabetic there’s no end in sight, this is it, and it’s a relatively complication free life (many people reverse their complications when they bring their A1C down to normal) vs. one with inevitable complications. So, perhaps it was too hard for you after a year (you didn’t say, but I assume you are not a type one diabetic), but that is a choice you can make. Not I.

Make sure you’re eating whole, unprocessed foods when on keto. There are different types of keto diets, and some, like dirty keto, may be low-carb but they’re still full of inflammatory foods. Learn more about how dirty keto works. Your best anti-inflammatory game plan is to emphasize good fats, grass-fed proteins, and fresh, organic vegetables, like on the Bulletproof Diet. Learn more with this Bulletproof Diet Roadmap.
Initial research has found that the diet can help maintain lean muscle mass in active women — even as they shed pounds — and may also lead to increased appetite suppression. "A keto diet is an option for people looking to lose overall weight, lower fat mass, and even build muscle. As a dietitian who focuses on sports nutrition and weight loss, I also recommend it for my clients who need a strong break from their sugar cravings, as it lessens blood sugar spikes and the cravings that can accompany high sugar intake," Nisevich Bede says.
A recent pilot study put five patients on the ketogenic diet (less than 20 grams per day of carbohydrate). At the end of six months, the average weight loss was 28 pounds (but this wasn’t the most surprising finding). Each patient underwent a liver biopsy, and four of the five patients had a reduction in liver fat, inflammation, and fibrosis. However, this is a small pilot study that also used supplements, so the results are not conclusive. What does the rest of the research say?
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.
Thank you for your objective review of the Keto Diet. I am not overweight but decided to try the Keto lifestyle because I have a lot of inflammation issues, including asthma and osteoarthritis. I had also been experiencing uncomfortable intestinal issues. I have been following the Keto lifestyle for 4 1/2 weeks, and I feel so much better- especially my stomach! I am eating a ton of leafy greens, broccoli and cauliflower. I am also enjoying Brussel sprouts, whole avacados and zucchini. I think the reason this is working well for me is because my body chemistry loves all the vegetables, good fats and protein. I also think that taking away sugar has had a big impact on how I feel. I’m just not eating grains and sugar. lots more veggies, berries, and consciously incorporating healthy fat. My stomach is flat again, and I have no more bloating or constipation. I have only lost 5 pounds, but I think my system is clean and operating better than it has in years. My point is that every person’s body chemistry is different. The Keto lifestyle seems to be what My body needed to feel my best. I did experience “the Keto flu” about a week into it, but it was short lived. I think that to be successful it is really important to eat a wide variety of veggies and good fats every day.
The answer is yes! In the years that Dr. Cabeca has been using the keto diet to help treat women, especially those in perimenopause or menopause, she’s hardly ever seen the diet fail to produce benefits. Her clients and patients have experienced weight loss, improved blood sugar control, better quality sleep and reduced menopause symptoms like hot flashes or night sweats.
The diet calls for consuming high amounts of fat, a moderate amount of protein, and a very limited amount of carbs. It’s usually broken down to 75, 20, and 5 percent of your daily calories, respectively, says Pamela Nisevich Bede, RD, a dietitian with Abbott’s EAS Sports Nutrition in Columbus, Ohio. Compare that with the typical American diet — which is usually 50 to 65 percent carbs — and it’s safe to say this is a completely different way of eating, Nisevich Bede says.
A related clinical diet for drug-resistant epilepsy is called the medium-chain triglyceride ketogenic diet, in which MCT oil is extensively used because it’s more ketogenic than long-chain triglycerides. (13) Another dietary therapy for epilepsy called Low Glycemic Index Treatment (LGIT) was developed in 2002 as an alternative to the keto diet. LGIT monitors the total amount of carbohydrates consumed daily, and focuses on carbohydrates that have a low glycemic index.) (14)
This high fat/low carb diet may also help improve certain other neurological disorders like Alzheimer’s disease and Parkinson’s disease,3 according to the Epilepsy Foundation. More than half the children with epilepsy who were put on the diet experienced half as many seizures, while 10 to 15 percent of the patients who followed this diet became seizure-free.
Keto decreases inflammation and improves brain function — so much so that Alzheimer’s patients who switch to a keto diet actually begin to recover their brain function, which up until now was unheard of. So there’s that. (Dale Bredesen and Mark Hyman have discussed these on the Bulletproof Radio podcast. Check out Dale’s episode here, and Mark’s here.)
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’.
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.
The keto diet has been shown to help people lose weight in the short term; however, the long-term benefits of the diet aren't as clear, according to the Mayo Clinic. The diet is named for ketosis, which is the condition the body goes into when following the plan. In ketosis, the body uses ketone bodies, or water-soluble molecules produced by the liver and the breakdown of fatty tissue for cellular energy as opposed to sugars from ingested carbohydrates. And in some people, this results in weight-loss.
The good news is, it is not necessary to stay on a ketogenic diet at all times to reap this benefit. Our ancestors went through fast and feast cycles and the body is designed for flexibility. We may be able to reduce cancer risk, prolong life, improve brain function, and benefit from ketosis otherwise by being in ketosis or fasting a few days a week.
What others (many of them) out there provide is just incomplete knowledge, claims, and advises that are not backed by enough evidence. And they do it all for the sake of pioneering in the debate/argument. Just because someone else is wrong about something, doesn’t automatically make you right. I have spent the complete day searching for Keto, learning about it, the risks, and how to implement it. And my search ended right here on this article. I feel I am finally ready to adapt and take the benefits of it. Thank you, Jordan for providing us with such an informational piece of writing. 🙂
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
If a person does not like his or her body, he or she will not be able to have the same amount of confidence as someone who loves their body. It is very important to be confident for a person to do well in his life. Without confidence, no one really takes you seriously and you are unable to impress anyone or show your talents to the world. To make this happen, this formula increases confidence in the user so that they can be more inspired from their own bodies rather than others.
If you’re a part of our community on Facebook, you may remember seeing a study I recently posted regarding the long-term impacts of the ketogenic diet in a study of obese patients. The study, available thanks to the US National Library of Medicine and the NIH, had some very interesting findings on the impact of diet on brain and body health, and my post on the subject saw a lot of traction. Because of that, and because the findings have such importance, I wanted to share the research with you here. The study shows that the ketogenic diet has efficacy as a treatment for Alzheimer’s, epilepsy, depression, migraines, and many other illnesses that plague huge portions of our population. I encourage you to read this study and to learn more.
so I won’t repeat it all here. The original study that claimed calcium supplements caused heart disease was widely publicized when it came out but unless you had a subscription to the British Medical Journal you wouldn’t be aware of the serious objections published in subsequent issues. In particular, Lappe & Heaney reported the complete opposite result – calcium supplementation REDUCED heart disease versus placebo.
Many people on a ketogenic diet report sleeping much deeper, says Pamela Ellgen, a personal trainer and author of Sheet Pan Ketogenic. However, during the adjustment period (the first three to five days after you start keto), you may experience insomnia or difficulty staying asleep. This will end once your body adjusts to ketosis and burning stored fat. Then, you may find you’re able to sleep longer, sleep deeper, and feel more relaxed and rested when you wake up. Here are 15 things you need to know before starting the keto diet.
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?
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.”
Now, I know what you are going to say, “I can take a break from the diet anytime.” What do you think happens when you take that “break”? As soon as you start consuming a normal amount of carbohydrates again, you immediately go out of ketosis or the fat burning state, and your body starts storing fat again immediately. In other words, you immediately start gaining weight. So whatever weight you lost on the diet, you gain back right away. How healthy do you think it is for your body to be in a starvation mode, then in a feeding frenzy, making up for lost time?
Use a Magnesium Supplement: Unless you are experiencing diarrhea, a magnesium supplement can work great for helping balance electrolytes and hydration levels. As you can see, magnesium can help keto-adaptation in many ways. Using 1 gram of the L-threonate form 3x daily is my general recommendation. If diarrhea occurs, lower to once or twice a day until it subsides.
Make things yourself. While it’s extremely convenient to buy most things pre-made or pre-cooked, it always adds to the price per pound on items. Try prepping veggies ahead of time instead of buying pre-cut ones. Try making your stew meat from a chuck roast. Or, simply try to make your mayo and salad dressings at home. The simplest of things can work to cut down on your overall grocery shopping.
Author’s note: I want to stress again the importance of consulting with your doctor before you try ketogenic dieting. The more I study this area of science, the more I realize that every individual is extremely unique when it comes to health issues and there are a ton of reasons why you should NOT go full-on keto (especially if you are prone to kidney, heart, or gallbladder issues). That being said, for many people this form of eating is life changing, and the amount of scientific research supporting a ketogenic lifestyle is significantly increasing. Subscribe to my newsletter to stay posted when I publish new articles, and I’d appreciate any and all feedback/corrections on the content I’ve written above. Thanks! (Image credit)
“Rapid, significant weight loss is a common side effect of the keto diet because of the water losses that occur as carbohydrate stores are depleted,” says Clark. In a study in the American Journal of Clinical Nutrition, obese men following a modified version of the ketogenic diet, with high protein and low carbs, lost about 14 pounds in one month, compared with the control group, which lost about 10 pounds on a high-protein, medium-carb diet.

Your liver oxidizes fatty acids to produce three ketone bodies — β-hydroxybutyrate, acetoacetate and acetone — that provide an alternative to glucose to fuel your brain and other tissues. And most organs, including your brain, thrive on ketones. Increased ketone levels replace glucose as your primary energy source, reducing need for gluconeogenesis and sparing protein breakdown. (4)
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.
Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show specific very-low-carb diets help people with metabolic syndrome, insulin resistance, and type 2 diabetes. Researchers are also studying the effects of these diets on acne, cancer, polycystic ovary syndrome (PCOS), and nervous system diseases like Alzheimer's, Parkinson's, and Lou Gehrig's disease.
What is the ketogenic diet exactly? The classic ketogenic diet is a very low-carb diet plan that was originally designed in the 1920s for patients with epilepsy by researchers working at Johns Hopkins Medical Center. Researchers found that fasting — avoiding consumption of all foods for a brief period of time (such as with intermittent fasting), including those that provide carbohydrates — helped reduce the amount of seizures patients suffered, in addition to having other positive effects on body fat, blood sugar, cholesterol and hunger levels.
