The most common side effects are constipation that can be supported with some dietary adjustments and laxatives. Other side effects that may occur that are relatively minor and transient include: kidney stones, low sugars, nausea, vomiting, diarrhea, sleepiness. There are some reports of longer term side effects that may include higher cholesterol, reduced bone health, kidney stones, slower linear growth velocity and abnormal heart rhythm.
The second is called LDL-P which measures the number of LDL particles in the blood. Sometimes, there is a correlation – more LDL particles means that you can have higher levels of LDL-C. However, larger LDL molecules can grow and carry more cholesterol – leading to a discordance in which LDL-C and LDL-P are not necessarily proportional. When this happens, LDL-C and LDL-P are said to be “discordant.”
Leftovers will be another thing we will take into consideration. Not only is it easier on you, but why put yourself through the hassle to cook the same food more than once? Breakfast is something I normally do leftover style, where I don’t have to worry about it in the morning and I certainly don’t have to stress about it. Grab some food out the fridge, pre-made for me, and head out the door. It doesn’t get much easier than that, does it?
Proponents of the super-high-fat, low-protein approach argue that protein kicks the body out of ketosis by supplying amino acids for gluconeogenesis (simply put, turning non-carbs into fuel); however, research indicates that the impact of dietary protein on gluconeogenesis and glucose flux is nearly negligible, making this argument irrelevant. (42) In my practice, we have found that usual protein intakes (15 to 20 percent of calories) do not have appreciable effects on blood ketone levels. Besides, a super-high-fat, low-protein diet typically has more drawbacks than benefits—it may cause weight gain, muscle loss, fatigue, and chronic hunger. Don’t be afraid of including plenty of protein in your ketogenic diet; protein is a powerful tool that will satiate your appetite while facilitating fat loss and preventing muscle loss.
The ketogenic diet also has been used in glycogenosis type V (McArdle disease), which is caused by a defect in the muscle-specific isozyme of glycogen phosphorylase. Glycogen phosphorylase is necessary to break down glycogen into free glucose for use as an energy source in muscles. When the ketogenic diet was applied to a patient with this disorder (presumably providing an alternative means of energy production), the patient’s exercise tolerance improved and there was a trend toward decreased baseline creatine kinase levels [22, Class III].
The first study looking at the ketogenic diet and cancer was published in 1995 in the Journal of the American College of Nutrition. In it, researchers recruited two young female patients at the University Hospitals of Cleveland. Both had Glioblastoma Multiforme (GBM), a form of cancer that starts in the brain and rapidly spreads throughout the body.
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]
Since this is my full-time job, donations really help me keep afloat and allow me to post as much to the website as I do. I really appreciate any donation you want to give, but you can change the price yourself. I’ve added in $15 as the suggested price. I think that’s a very fair price considering other websites are charging in the hundreds of dollars, and I’ve seen what they are like on the inside.
Acid Reflux/GERD (heartburn): people who suffer from acid reflux or chronic heartburn will find great relief after adopting a keto diet, especially if all grain and fermentable carb sources (FODMAPS) are eliminated from the diet. In fact, I believe that some of the beneficial effects of a ketogenic diet are rooted in the elimination of toxins in foods that the keto diet limits.

By the time I began medical school in 1979 I had read the pioneering work of Weston A. Price, DDS, the American dentist and researcher. Beginning in the late 1920s, Dr. Price, accompanied by his wife, spent seven years traveling the world evaluating isolated groups of people living and eating according to long-standing tradition. Today such a study would be impossible, since just about everyone everywhere has adopted the “Western” way of living and eating, down to jeans and junk food.
Thanks for this inputs. 20 years ago I gain 17 pounds a year for 5 years. I was healthy but my dr told me start diet, any diet just come back in a month I want to see you start loosing… I started Atkins and lost 7 pound in a month. She was checking my progress every six months and checking my condition. I lost 64 pounds in 3 years. Now I started eating out of control. I am eating healthy but too much… I gain 40 pound back after 20 years. Now I will start again my Atkins to take off 30 pounds…
In both patients, levels of blood glucose decreased to low/normal levels and ketones increased by 20 to 30 times within seven days of starting the ketogenic diet.  Results from scans indicated that there was a 21.8% decrease in glucose uptake at the tumor sites in both subjects. Lower glucose uptake is a strong indicator that a tumor is shrinking in size.
Traumatic brain injury (TBI) is an injury caused by a blow, bump, or jolt to the head that significantly impairs brain function. TBI is common in military personnel, car accident survivors, and athletes involved in contact or high-risk sports. If left untreated, TBI can cause severe impairments in thinking, memory, and emotional regulation. Interestingly, a ketogenic diet may be an effective strategy for reducing the harmful effects of TBI.
Another mouse study cited by Seyfried is one in which dietary restriction was reported to promote vessel maturation in a mouse astrocytoma model. Given that tumor angiogenesis is one of my scientific interests and I have a fair number of publications on the topic, I was interested. Unfortunately, I ended up being disappointed. This was another syngeneic model (i.e., a mouse tumor implanted in mice of the same strain from which the tumor was isolated as a cell line, like the one discussed above). Although it showed increased tumor vessel maturation (which is one mechanism by which inhibitors of angiogenesis work), I wasn’t quite convinced, because there was a distinct lack of quantification of the phenomenon, and the microscopy appears not to have been blinded, something that’s critical to avoid unconscious bias in the results. It’s not surprising that this result, which, if more convincing evidence had been obtained, could easily have appeared in Cancer Research, was published in a low tier journal. It’s an OK study, but not fantastic. Certainly it didn’t lead me to smacking myself in forehead and saying, “Of course!”
Importantly, cholesterol doesn’t travel around your bloodstream on its own. As a hydrophobic (water-repelling) substance, it must be packaged within lipoproteins to move around the bloodstream. So that means when we talk about blood cholesterol levels, we’re referring to the amount of cholesterol contained in different lipoprotein particles. In addition to cholesterol, these lipoprotein particles also contain special proteins called apolipoproteins, triglycerides and other compounds.

Compared to TBI, the amount of scientific literature documenting the beneficial effects of a ketogenic diet for epilepsy is vast. The ketogenic diet was first introduced as a therapy in the 1920s, when doctors learned it could successfully treat seizures in children with refractory epilepsy. (27) Interest in the ketogenic diet waned when antiepileptic drugs were introduced in the 1960s and ’70s; however, the ketogenic diet has experienced a recent resurgence in popularity in the epilepsy community, particularly among those suffering from drug-resistant epilepsy.
Over the past two years Feldman, a software engineer with a strong interest in science, has performed several dozen experiments on himself and collected data from a number of other keto and low-carb dieters whose cholesterol levels have increased far beyond the “optimal” range. However, whether this is problematic or not isn't entirely clear, especially since their other biomarkers typically improve or remain stable.
Taking your first step into the ketogenic diet is an exciting phase for your health. But before coming up with an actual ketogenic diet food list, it's important to first take a look at what you're eating now and take out anything that's unhealthy. This means that you have to remove sugars, grains, starches and packaged and processed foods from your diet. Basically, anything that won't add to your new eating regimen has to go. This is what I call a "pantry sweep."
Jimmy Moore: Yes, so it’s a spiral effect. It’s not necessarily the high triglycerides, but the high triglycerides definitely is an indication you’re not eating something correctly that might be causing those issues. One other thing about the diet we hadn’t talked about that I thinks really important needs to come out is protein. When you’re eating protein in excess, it can act just like carbohydrate in the body, which would show up in your triglycerides, would show up on your blood sugar and your fasting insulin levels. That’s important too. Sometimes Leanne, they’ve heard you talk about low carb, high fat, okay great. I’m going to have green beans and I’m going to have a chicken breast and then I’m going to put half of a table spoon of butter, man that is so high fat. I’m going to do so good and then they wonder an hour and a half later, “Why am I so hungry?”
Seizure reduction can occur very soon after the ketogenic diet is initiated or it may take several months. During this time, it is important to remain committed to keeping the diet consistent and work with your keto diet team who will help you fine tune the diet to achieve the best seizure control. Commitment to consistency to the diet recommendations is important to determine effectiveness of the therapy in controlling seizures.
Serum cholesterol and triglycerides may increase, especially during the first 6 months. These levels may even out by 6 months, then decline often back to normal values. It is rare to stop the diet due to a cholesterol problem, especially after 1-2 years of use. Adjustments to the diet (e.g., increased protein and polyunsaturated fat) can be made in children with significantly high cholesterol and triglyceride concentrations.
Let me say out front I have no problem with scientists who propose a theory, in short papers or in the case of Dr. Seyfried, in long, detailed books. I do have a problem when scientists go a step further, insisting in the absence of any significant human data or even impressive case histories they have unraveled the mystery of cancer. I am also quite surprised, in the case of Dr. Seyfried, that both alternative and conventional practitioners have risen up in a loud chorus of enthusiasm, as if indeed Dr. Seyfried’s theories are correct, and that he has solved the cancer riddle.
Over half of children who go on the diet have at least a 50% reduction in the number of their seizures. It can start to help after just one week, but more often it can take a few weeks up to several months to judge whether it will be effective. If the diet successfully controls seizures, it may be continued for several years under the supervision of the child's health care team. Many children on the ketogenic diet continue to take seizure medications but on average they require one less medication and often the dosage of remaining ones is lowered.
We also maintain a certain amount of stored sugar as glycogen, found in the liver and muscle and formed when glucose molecules link up to one another in complex chains. In times of need and if deprived of dietary carbohydrates, our liver and muscle cells can break down glycogen into glucose for release into the bloodstream. Our liver cells can also, when necessary, convert certain amino acids such as alanine into glucose.
The ketogenic diet has been studied in at least 14 rodent animal models of seizures. It is protective in many of these models and has a different protection profile than any known anticonvulsant. Conversely, fenofibrate, not used clinically as an antiepileptic, exhibits experimental anticonvulsant properties in adult rats comparable to the ketogenic diet.[58] This, together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs, suggests a unique mechanism of action.[56]
Your medical team can recommend cookbooks and websites that have recipes that can help to make the diet easier to adhere to. Although starchy food like pancakes, muffins, crackers and breads are eliminated or consumed in only small amounts on ketogenic diets, it is possible to make delicious ketogenic versions of these foods using things like nut flours and ground flax or other seeds.
One study assessed the effect of dietary interventions on quality of life, cognition and behavioural functioning, reporting participants in the KD group to be more active, more productive and less anxious after four months, compared to the control group. However, no significant difference was found in quality‐adjusted life years (QALYs) between the KD group and control group at four or 16 months (GRADE rating very low).

Calorie restriction (CR) and a ketogenic diet (KD) target the same molecular pathways that are also targeted individually by drugs to improve cancer treatment outcomes. Arrows indicate activation, truncated lines inhibition. Carbohydrate (CHO) restriction up-regulates fatty acid oxidation and ketogenesis (beneficial for normal tissues) and impairs glycolysis and glutaminolysis (detrimental to tumor cells). Full study here.
Research has indicated that a ketogenic diet raises the stress hormone cortisol to increase energy levels in the face of reduced carbohydrate availability. However, it is still up for debate whether this increase in cortisol is harmful or innocuous. Nonetheless, I recommend taking extra care to manage your stress while on a ketogenic diet. Getting plenty of sleep, exercising, and engaging in a regular stress-reduction practice can help you keep your baseline stress levels low and reduce the potential for chronically elevated cortisol.
The study also found that two types of bacteria, called Akkermansia muciniphila and Parabacteroides, were elevated by the diet. When these two types of bacteria were given in combination to mice that didn't have their own gut bacteria, the anti-seizure effect of the keto diet was restored. What's more, this combination of bacteria protected against seizures even if the mice were fed a nno-keto diet.
If you’ve decided to move forward in trying the keto diet, you will want to stick to the parameters of the eating plan. Roughly 60 to 80 percent of your calories will come from fats. That means you’ll eat meats, fats, and oils, and a very limited amount of nonstarchy vegetables, she says. (This is different from a traditional low-carb diet, as even fewer carbs are allowed on the keto diet.)
