Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[34] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[35] On the other hand, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria and other rare genetic disorders of fat metabolism.[9] A person with a disorder of fatty acid oxidation is unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their body would consume its own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[36]
A majority of the meal planning for the Mediterranean diet consists of fresh fruits and vegetables. A sample days meal menu consists of: a pumpkin-gingerbread smoothie for breakfast, Macaroni with Milk (Macoroni oil-Hali) for lunch, and Trout with Wilted Greens for dinner. Your suggested snacks during the day: Mango-Pear Smoothie, cashews and raisins, low-fat ricotta cheese with peaches, hummus, and seed and nut snack bars.

Children who discontinue the diet after achieving seizure freedom have about a 20% risk of seizures returning. The length of time until recurrence is highly variable but averages two years. This risk of recurrence compares with 10% for resective surgery (where part of the brain is removed) and 30–50% for anticonvulsant therapy. Of those that have a recurrence, just over half can regain freedom from seizures either with anticonvulsants or by returning to the ketogenic diet. Recurrence is more likely if, despite seizure freedom, an electroencephalogram (EEG) shows epileptiform spikes, which indicate epileptic activity in the brain but are below the level that will cause a seizure. Recurrence is also likely if an MRI scan shows focal abnormalities (for example, as in children with tuberous sclerosis). Such children may remain on the diet longer than average, and it has been suggested that children with tuberous sclerosis who achieve seizure freedom could remain on the ketogenic diet indefinitely.[45]


Basically, the effect of exercise on our weight is vastly overrated. That’s why it’s only number 15 on this list. There are other things you need to take care of first. It’s not a good idea to eat bad food, drink sugar water (so-called “sports drinks”) or be on medications which force you to exercise for hours daily just to compensate. Metaphorically that’s like digging a hole, into which you put your ladder, on which you stand and paint the basement-level windows of your house.
Cheese isn’t traditionally thought of as something you consume to encourage weight management, but calcium-rich Parmesan, when eaten in moderation, can help stave off sugar cravings that can easily lead to weight gain. How does that work, you ask? The native Italian cheese contains the amino acid tyrosine (a building block of protein) which has been shown to encourage the brain to release dopamine without any unhealthy insulin spikes. What’s more? The combination of calcium and protein found in dairy products such as Parmesan has been found to increase thermogenesis—the body’s core temperature—and thus boost your metabolism.

In terms of weight loss, you may be interested in trying the ketogenic diet because you’ve heard that it can make a big impact right away. And that’s true. “Ketogenic diets will cause you to lose weight within the first week,” says Mattinson. She explains that your body will first use up all of its glycogen stores (the storage form of carbohydrate). With depleted glycogen, you’ll drop water weight. While it can be motivating to see the number on the scale go down (often dramatically), do keep in mind that most of this is water loss initially.
There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[53]
“Just because the scale isn’t moving, doesn’t mean that you are making zero progress toward your fitness goals and dream body,” explains Mike Roussell, PhD, co-founder of Neutein, a dietary supplement meant to improve memory and performance. “It’s easy to think you’ve hit a plateau when you don’t see additional weight loss on the scale, but that’s not always truly the case."
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
My principal hope in this article is to provide journalists with a resource to do what basic journalism demands, namely to ensure that stories are scientifically balanced and accurate. At the end of this post I provide contacts for some of the credentialed experts who helped me compile this research. Reporters, please seek out these or other low-carb diet experts so you can provide accurate, up-to-date information for your readers.
There is a lack of scientific research when it comes to the long-term effects of the keto diet. When it comes to healthy eating and weight loss, creating sustainable, lifelong changes will result in the best outcomes. Most importantly, think about how this restrictive eating plan will fit into your lifestyle, and if you are willing to give up what may be some of your favorite foods. It’s important to make time for yourself to prepare meals at home and get regular exercise. Strive for progress, not perfection.

When your body burns its stores of fat, it can be hard on your kidneys. And starting a ketogenic diet -- or going back to a normal diet afterward -- can be tricky if you’re obese because of other health issues you’re likely to have, like diabetes, a heart condition, or high blood pressure. If you have any of these conditions, make diet changes slowly and only with the guidance of your doctor.

Adequate food records were available for analysis in a proportion of participants at each of the 4 timepoints (Table ​(Table2).2). Participants completed food records at a mean of 2.5 and a median of 3 timepoints. In general, comparing baseline to subsequent timepoints, mean carbohydrate intake decreased substantially and energy intake decreased moderately while protein and fat intake remained fairly constant.

"The eating plan focuses on reducing sodium intake and eating more fruits and vegetables," says Amy Gorin, MS, RDN, owner of Amy Gorin Nutrition in the New York City area. "It also emphasizes eating whole foods — such as fruits, vegetables, whole grains, fish, poultry, beans, nuts, and vegetable oils — and limits foods high in saturated fat. That includes fatty meats, full-fat dairy, and tropical oils like palm kernel oil, palm oil, and coconut oil. It also limits sugar-sweetened beverages and foods."
It is completely wrong to discuss “average lifespan”. The average lifespans of pre-industrial peoples is heavily reduced by infant and early childhood mortality, which has nothing to do with lack of fresh fruit. Once you remove this bias in the numbers, pre-industrials can have lifespans almost as long as ours. And usually without many of the degenerative diseases that bother our middle and old ages.

The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was developed for treatment of paediatric epilepsy in the 1920s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter.[1] Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs)—made from fatty acids with shorter carbon chains than LCTs—are more ketogenic. A variant of the classic diet known as the MCT ketogenic diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. As less overall fat is needed in this variant of the diet, a greater proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices.[4][5]

I am confused by this statement, as there are many wonderful “white” substitutions that taste great, and don’t make me feel like i am missing out. One of the things I thought I was just going to die if I couldn’t ever have it again, was waffles with peanut butter & maple syrup. Guess what….there is a sub for that! I am T2D, and my doctor, who specializes in diabetes, told me to stop eating sugar, carbs and she said that in a perfect world, I would stop eating fruit, as it contains sugar. That’s when I found Keto, on my own. I’ve been on it for a little over a month or so, and have lost 12lbs, but more importantly, BS levels that were averaging in the 200’s are now lower than the 90’s, consistently… The highest number I’ve tested was 97, after I ate dinner & had a satisfying bowl of Keto ice cream. I’ve been diagnosed Diabetic for approx 4yrs, but am certain I was diabetic for probably 3 yrs prior to that. I’m not over weight, and did not have the hope of “losing weight and getting off meds”. This has been my answer, and I truly think that if we did live in a perfect world, more things like this would be taught to those of us who need better choices than medications. There are so many other things in the world that are suppressed due to greed of Big Pharma & Government. Let’s start helping our fellow man be healthy & heal….
The aim is far broader than suggested by the article here: It’s not just about what you put in your mouth – it’s also about timing and exercise. There are three ways to be in ketosis – which simply means that “fat burning” and not being dependent on sugars. Fasting puts a man into ketosis in 3 days and a woman by 2 days. Endurance exercise gets you there in a couple of hours. Eating a high fat diet will do it too. The goal however is hidden by the detail – it is to acquire a “Flexible Metabolism”. The aim is to switch on the full fat burning capacity and keep it running – which takes from between 4 to 12 weeks physical adaptation (for the muscles to fully be able to use ketones). The heart runs approximately 27% more efficiently on ketones than on glucose! The brain works better too – Alzheimer’s being referred to by researchers as “diabetes 3”. Once you have a Flexible Metabolism you can consume carbs during or after exercise without dropping out of ketosis – though this depends on your own bio-individuality. I can eat quite a lot of carbs – without losing ketosis – my partner cannot.

In 2008, researchers conducted a 24-week study to determine the effects of a low-carbohydrate diet on people with type 2 diabetes and obesity. At the end of the study, participants who followed the ketogenic diet saw greater improvements in glycemic control and medication reduction compared to those who followed a low-glycemic diet. A study from 2017 found the ketogenic diet outperformed a conventional, low-fat diabetes diet over 32 weeks in regards to weight loss and A1c. A 2013 review reports again that a ketogenic diet can lead to more significant improvements in blood sugar control, A1c, weight loss, and discontinued insulin requirements than other diets.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
These carbohydrate recommendations are not PER DAY, they are per meal. This is the major difference between Ketogenic diets and a consistent, low carbohydrate diet CDEs advocate for. 30-45 carbs per meal is considered a low carb diet. Eating this in the form of a Mediterranean diet is what I recommend and what my article outlined. In a perfect world, we try to have people steer clear of anything artificial or processed when possible. Just eat fresh foods, like our grandparents did, who never had these types of health problems.

Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.


“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
What the expert says: ‘Like with atkins, you will lose weight quickly. The ketogenic diet is used in medicine, but under strict supervision and for set periods of time, so with appropriate support it can be safe in the short to medium term. The brain does use glucose as its fuel of choice, so ‘brain fog’ lethargy are common side effects. You’ll known when your body is running off ketones by your breath – it’s known as ‘keto breath’, and it’s bad. It also can affect your ability to exercise by due to a lack of quickly accessible energy.
And it’s not just this study, either. Several other studies have found  that keto leaves rodents unable to process carbs,[7] leads to insulin resistance,[8] and, more long-term, causes non-alcoholic fatty liver disease, which is when your liver accumulates lots of fat and begins to shut down.[9][10] Triglycerides and inflammation go way up, too.[11]
Thank you SO much for this! My husband approached me about the Mediterranean diet being good for depression and suggested I give it a try. But I already knew this was not the best term to describe what I needed, even before reading your article on the subject. However, I did have an idea of what they meant and I have struggled to find recipes that fit the bill. Too many well-meaning people have made it more “healthful” by cutting back on the fat. ANYWAY . . . This little meal plan is going to be immensely helpful to me and I am poking all around the site and your social media. Thank you for sharing!
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.

For the ketogenic eating plan, participants were instructed to reduce non-fiber-containing carbohydrates to between 20 and 50 grams a day, with no calorie restriction. The group following the plate method were told to eat their meals on a nine-inch plate, filling half of it with non-starchy vegetables (eg, greens, peppers, broccoli, carrots), ¼ of the plate with whole grains (eg, brown rice, sweet potatoes, whole wheat bread) and adding lean protein (eg, skinless chicken, turkey, fish, and seafood) to the last quarter of the plate.1


I have been a type 1 diabetic for most of my life. I live a very active lifestyle of long distance running and hiking. I’ve always had a very healthy diet, but would still have those after meal blood sugar spikes that would leave me feeling unwell. I decided to try the keto diet to see how my blood sugar did It’s been amazing. I’ve cut my insulin in half and my head is clear. I no longer have the brain fog. I sleep better and have more energy. I have been doing it for a year and have no desire to go off of it.

Unlike the keto diet, the Atkins diet doesn’t necessarily advocate increased fat consumption. Still, you might increase your fat intake by limiting carbohydrates and eating more animal protein. The potential drawbacks are similar. Aside from a high saturated fat intake, there is the possibility of low blood sugar, or hypoglycemia, from restricting carbs too much. This is especially true if you take medications that increase insulin levels in the body and don’t change your dosage. Cutting carbs on the Atkins diet can potentially aid weight loss and help you control diabetes symptoms, but there aren’t enough studies to suggest that Atkins and diabetes control go hand-in-hand.
If you’re looking to get a jump start on your health and fitness goals this year, you may be thinking about trying the ketogenic diet. Maybe you’ve heard the phrase before — it’s a huge diet buzzword — but aren’t sure what it means. Here’s a primer: The ketogenic diet is an eating plan that drives your body into ketosis, a state where the body uses fat as a primary fuel source (instead of carbohydrates), says Stacey Mattinson, RDN, who is based in Austin, Texas.
