As with other customized properties of the diet, the consumption of dairy is individualized. If digestive or glycemic problems develop due to the lactose and casein in dairy, then dairy may need to be avoided. If you can tolerate it, opt for lower carbohydrate dairy like cheese, heavy whipping cream, and butter, rather than higher carbohydrate products like milk.


Restricting your calories may be important for some individuals depending on their goals. Additionally, it may aid in the initiation of ketosis; however, not everyone will require calorie tracking to maintain a deficit. It is not uncommon for caloric-restriction to occur inadvertently as a ketogenic diet tends to be satiating, leaving individuals satisfied with fewer calories.
Alcoholic ketoacidosis (AKA): AKA is a ketone-producing state that may occur following excessive alcohol consumption for long periods of time. When alcohol is metabolized in the liver, ketones are produced. Furthermore, as with other ketogenic states, certain biological changes, specifically at the hormonal level, occur to promote fat metabolism and ketone production. It is critical to note that AKA will not occur if the alcohol consumption is coupled with sugar.
First reported in 2003, the idea of using a form of the Atkins diet to treat epilepsy came about after parents and patients discovered that the induction phase of the Atkins diet controlled seizures. The ketogenic diet team at Johns Hopkins Hospital modified the Atkins diet by removing the aim of achieving weight loss, extending the induction phase indefinitely, and specifically encouraging fat consumption. Compared with the ketogenic diet, the modified Atkins diet (MAD) places no limit on calories or protein, and the lower overall ketogenic ratio (about 1:1) does not need to be consistently maintained by all meals of the day. The MAD does not begin with a fast or with a stay in hospital and requires less dietitian support than the ketogenic diet. Carbohydrates are initially limited to 10 g per day in children or 20 g per day in adults, and are increased to 20–30 g per day after a month or so, depending on the effect on seizure control or tolerance of the restrictions. Like the ketogenic diet, the MAD requires vitamin and mineral supplements and children are carefully and periodically monitored at outpatient clinics.[48]
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.

Positive science on ketosis coupled with personal successes passed by word-of-mouth have driven more people to explore the ketogenic diet, says Volek. More recently, the keto diet hints at having a promising therapeutic role in cancer, Alzheimer’s, Parkinson’s and polycystic ovary syndrome (PCOS). Research is still early in many areas, but Volek suspects there will more definitive answers on the wider scope of the diet’s benefits within the next decade.


The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this impulse from one neuron to another is typically controlled by neurotransmitters, though there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily done by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that releases excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, since seizures may be discouraged by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons.[7]

Another difference between older and newer studies is that the type of patients treated with the ketogenic diet has changed over time. When first developed and used, the ketogenic diet was not a treatment of last resort; in contrast, the children in modern studies have already tried and failed a number of anticonvulsant drugs, so may be assumed to have more difficult-to-treat epilepsy. Early and modern studies also differ because the treatment protocol has changed. In older protocols, the diet was initiated with a prolonged fast, designed to lose 5–10% body weight, and heavily restricted the calorie intake. Concerns over child health and growth led to a relaxation of the diet's restrictions.[19] Fluid restriction was once a feature of the diet, but this led to increased risk of constipation and kidney stones, and is no longer considered beneficial.[18]

A simple standby, but one that ketoers adore. 2 or 3 fried eggs and some bacon might not sound like much, but it’s full of protein that will keep you full and energized all morning. Take the opportunity on the weekend to lay your bacon strips on a single cookie sheet and bake in the oven for 20 minutes at 400 degrees. The result is the best bacon you’ve ever had, in a big batch, with no sitting over a popping, hissing frying pan.

“You are literally starving” on an intermittent fasting diet, Keatley says. “Methods such as this are attractive as weight loss can go from one pound a week to four pounds, but this is mostly lean muscle which is essential to healthy functioning as you age and is very hard to get back once it is gone,” he adds. So…it’s not really recommended that you try this unless you hash it out with your doctor or nutritionist to make sure it's a fit for you and your lifestyle.
Implementing the diet can present difficulties for caregivers and the patient due to the time commitment involved in measuring and planning meals. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline needed to maintain the diet challenging and unpleasant. Some people terminate the diet or switch to a less demanding diet, like the modified Atkins diet or the low-glycaemic index treatment diet, because they find the difficulties too great.[42]
Instead of thinking about the total carbs you’re eating, assess what those carbs provide to you. Do the majority of your carbs come from fruit and vegetables, with a payload of fiber and disease-fighting antioxidants? Fantastic. Or are you consuming them in the form of added sugars (cookies, candy, soda) or refined flour? If you are, you know what to do.
The nerve impulse is characterised by a great influx of sodium ions through channels in the neuron's cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.[7]

Cravings: As one begins to eliminate carbohydrates from the diet, it is common to experience carbohydrate cravings. Several suggestions for conquering these cravings are outlined below. However, it should be noted that as the body keto-adapts, hunger and appetite should become suppressed. One interesting study found that when you increase the occupied volume inside of the stomachs of subjects, this led to feelings of perceived fullness.[17] This means by doing things like drinking more water and eating more high volume foods we can improve our feeling of fullness.
I have been eating this way (very low carb, high fat, protein in between) for around 3 years now. I have found that for me I can MAINTAIN quite easily at an ideal weight and eating to satiety, but in order to actually LOSE weight, I have to at least have a very small calorie deficit. And though the change is gradual, it is sustainable and quite immediate (just little by little). The amount of that calorie deficit required in order to drop excess varies a lot from one individual to the next though, I think. I am particularly intolerant to hunger, and so I cannot overly emphasize how small of a deficit I will allow for. The nice thing about that though is that the hunger is far more pleasant in the absence of carbs.
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.[54]
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.

“People are afraid of fat because they’ve been told that it’ll kill them,” says Mancinelli. What is confusing is that research today remains mixed. Some studies suggest that replacing saturated fat with polyunsaturated fat (and avoiding unhealthy trans fat) is important for mitigating heart disease risk, while others suggest that total fat and types of fat weren’t associated with cardiovascular problems, according to an article published in June 2018 in BMJ. (2) Deciding exactly how to eat then becomes confusing. What is helpful, the authors note, is to remember that food is more than a single nutrient, and it’s the overall quality of the diet that counts. (They do say that high-fat, low-carb diets still need more research to assess their long-term health benefits and risks.)
“Combining a super restrictive diet with long periods of non-eating is not good,” says Keatley. “The body will cannibalize its own muscle for energy if intake from food is too low but the body does not differentiate between something like a calf muscle or a heart muscle. Keep in mind all your important organs are made of smooth muscle and going on a diet like this may harm something like your bladder or lungs just as much as provide fat loss.”
The remaining calories in the keto diet come from protein — about 1 gram (g) per kilogram of body weight, so a 140-pound woman would need about 64 g of protein total. As for carbs: “Every body is different, but most people maintain ketosis with between 20 and 50 g of net carbs per day,” says Mattinson. Total carbohydrates minus fiber equals net carbs, she explains.

The ketogenic diet is calculated by a dietitian for each child. Age, weight, activity levels, culture, and food preferences all affect the meal plan. First, the energy requirements are set at 80–90% of the recommended daily amounts (RDA) for the child's age (the high-fat diet requires less energy to process than a typical high-carbohydrate diet). Highly active children or those with muscle spasticity require more food energy than this; immobile children require less. The ketogenic ratio of the diet compares the weight of fat to the combined weight of carbohydrate and protein. This is typically 4:1, but children who are younger than 18 months, older than 12 years, or who are obese may be started on a 3:1 ratio. Fat is energy-rich, with 9 kcal/g (38 kJ/g) compared to 4 kcal/g (17 kJ/g) for carbohydrate or protein, so portions on the ketogenic diet are smaller than normal. The quantity of fat in the diet can be calculated from the overall energy requirements and the chosen ketogenic ratio. Next, the protein levels are set to allow for growth and body maintenance, and are around 1 g protein for each kg of body weight. Lastly, the amount of carbohydrate is set according to what allowance is left while maintaining the chosen ratio. Any carbohydrate in medications or supplements must be subtracted from this allowance. The total daily amount of fat, protein, and carbohydrate is then evenly divided across the meals.[37]

Keto for Alzheimer’s Disease: One characteristic of Alzheimer’s disease is insulin resistance in the brain (hence why it’s now being referred to as type III diabetes), which robs this critical tissue of energy. Limiting glucose while introducing ketones may be an effective mechanism for replenishing the energy in the tissue. The higher level of ketone production accompanied with a ketogenic diet is another example as to why this diet is superior to one that simply restricts carbohydrate intake. Additionally, Alzheimer’s disease is characterized by beta-amyloid deposition, which may also be mitigated by the implementation of a ketogenic diet.


These affect your brain and spine, as well as the nerves that link them together. Epilepsy is one, but others may be helped by a ketogenic diet as well, including Alzheimer’s disease, Parkinson’s disease, and sleep disorders. Scientists aren’t sure why, but it may be that the ketones your body makes when it breaks down fat for energy help protect your brain cells from damage.
Option 3: "Make your own keto 'lunchable' with cubes of grilled chicken, a slice of nitrate-free ham, cheese cubes, pickle slices, a hard-boiled egg, a few raw grape tomatoes, raw veggies like cauliflower or broccoli, a few almonds or walnuts, guacamole, and ranch dressing," says Stefanski. (Looking for something meat-free? Here are 29 Vegetarian Keto Recipes for Plant-Based Eaters.)
Keto-adaptation occurs as tissues maximally increase their capacity to utilize ketone bodies for fuel. As glucose metabolism slows and fatty acid breakdown ramps up, ketones are synthesized and increasingly utilized for fuel. After a few weeks or months of increasing ketone and fat utilization, the body adapts to these new fuel sources. In addition to increased fat breakdown and ketone synthesis and utilization, keto-adaptation is associated with decreased and stabilized blood glucose levels.
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]
There’s also some evidence that it might help with type 2 diabetes. “An emerging body of research is finding that a keto plan may have some real benefits thanks to its ability to improve the body’s ability to use insulin and also help control appetite, which can result in easier weight loss,” says Karen Ansel, R.D.N., co-author of Healthy in a Hurry.

Carbohydrate-restricted ketosis: This type of ketosis mimics the same biological alterations seen during lengthy fasts, but without the complete restriction of food. Carbohydrate-restricted ketosis is achieved primarily through a very low-carbohydrate ketogenic diet. This restriction, in turn, results in reductions of insulin and blood glucose levels similar to that of fasting, which again increases blood ketone levels. For most individuals, nutritional ketosis is much more sustainable than fasting or starvation ketosis. Fasting can still have its place in a keto diet for beginners. Many individuals following a ketogenic diet like to implement a regular fasting protocol such as intermittent fasting (IF) (12–20 hours daily) or every-other-day fasts (EOD), depending on their goals. This practice is not critical for success on a ketogenic diet, but it can enhance the level of ketone production, and thus magnify the benefits.
In the 1960s, medium-chain triglycerides (MCTs) were found to produce more ketone bodies per unit of energy than normal dietary fats (which are mostly long-chain triglycerides).[15] MCTs are more efficiently absorbed and are rapidly transported to the liver via the hepatic portal system rather than the lymphatic system.[16] The severe carbohydrate restrictions of the classic ketogenic diet made it difficult for parents to produce palatable meals that their children would tolerate. In 1971, Peter Huttenlocher devised a ketogenic diet where about 60% of the calories came from the MCT oil, and this allowed more protein and up to three times as much carbohydrate as the classic ketogenic diet. The oil was mixed with at least twice its volume of skimmed milk, chilled, and sipped during the meal or incorporated into food. He tested it on 12 children and adolescents with intractable seizures. Most children improved in both seizure control and alertness, results that were similar to the classic ketogenic diet. Gastrointestinal upset was a problem, which led one patient to abandon the diet, but meals were easier to prepare and better accepted by the children.[15] The MCT diet replaced the classic ketogenic diet in many hospitals, though some devised diets that were a combination of the two.[10]
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there can also be other, less obvious benefits, such as less hunger and a steady supply of energy (without the sugar peaks and valleys we can get from high carb meals). This may help keep you alert and focused.
Alcoholic ketoacidosis (AKA): AKA is a ketone-producing state that may occur following excessive alcohol consumption for long periods of time. When alcohol is metabolized in the liver, ketones are produced. Furthermore, as with other ketogenic states, certain biological changes, specifically at the hormonal level, occur to promote fat metabolism and ketone production. It is critical to note that AKA will not occur if the alcohol consumption is coupled with sugar.
Electrolytes: To reiterate, maintaining electrolyte balances is critical on a ketogenic diet, in order to prevent side effects and the “keto-flu.” While this can be done exclusively through whole foods, some individuals may require additional sources. Sodium, magnesium, potassium, and in some cases, calcium, can all be replenished via supplementation.
When something is popular, it’s pretty much a guarantee that people are going to come up with new or easier ways of doing it. Enter the lazy keto and dirty keto diets. With lazy keto, people try to limit their carb intake to 20 to 50 grams a day but don’t really track it; with dirty keto, people generally follow the same macronutrient breakdown as "regular" keto, but it doesn't matter where those macronutrients come from.
There are three instances where there’s research to back up a ketogenic diet, including to help control type 2 diabetes, as part of epilepsy treatment, or for weight loss, says Mattinson. “In terms of diabetes, there is some promising research showing that the ketogenic diet may improve glycemic control. It may cause a reduction in A1C — a key test for diabetes that measures a person’s average blood sugar control over two to three months — something that may help you reduce medication use,” she says.
The meal plan is designed to ensure you get three balanced, healthy meals a day that address fiber, satiation, and adequate protein intake. The greatest part of a ketogenic diet is the fact that it spares muscle loss, where a carb-based diet doesn’t. Weight lost in a high carb, calorie-restricted diet will often come both from muscle and fat, whereas with keto, you can burn fat without sacrificing muscle. This is referred to often as “body recomposition” and leaves you with a much more preferred physique after weight loss.

At the start of a keto diet for beginners, it is not uncommon for an individual to experience rapid weight loss. This may concern some people, but it is worth noting that not ALL weight lost is body fat. When we lower our carbohydrate intake our insulin lowers, causing us to excrete more water. Additionally, reducing carbohydrate intake causes the body to break down glycogen stores (to initially maintain blood sugar levels); glycogen is the storage form of glucose that is located in our liver and skeletal muscle. The loss of both water and glycogen accounts for most of the weight loss in the first few days. Don’t be discouraged! Soon after, total body water and glycogen levels will balance out.


Lastly, if you're active, you might need to make some adjustments to take that into account. "For the first one to two weeks, temporarily reducing your exercise load can be helpful as your body adjusts to being in ketosis," he says. "Additionally, for those who have an intense workout schedule, carb cycling may be a good option." Carb cycling essentially means you'll increase your carb intake on the days you're doing exercise, ideally just two to three days per week. "While low-carb days may be around 20 to 30 grams of net carbs daily, high-carb days can range all the way up to 100 grams, although it can vary based on your size and activity level," says Dr. Axe.
