Ketogenic Diet And Parkinson’s

Is The Keto Diet Right For Me

Ketogenic Diet and Parkinson’s Disease

The keto diet can cause appetite suppression and as seen in all 3 studies weight loss. For some people with Parkinsons who are carrying extra weight this may be appropriate but for many struggling with poor appetite and unplanned loss of weight this dietary pattern may not be suitable.

If not well formulated the keto diet can lack fibre. A lack of dietary fibre can lead to or exacerbate constipation. to learn how to get an adequate amount of fibre on a keto diet.

The keto diet is very high in fat. If you suffer from gastroparesis or slow stomach emptying consuming very high-fat meals can cause symptoms such as nausea, stomach pain and bloating. As fat empties more slowly from the stomach this dietary pattern may not be suitable.

Study 1 Vanitallie Et Al

The first study, conducted in 2005, assigned 7 participants with Parkinsons to the keto diet for 4-weeks to determine if symptoms could improve on this diet. 5 participants completed the study. Urine ketones were measured daily. The macronutrient breakdown as a percent of total calories was 90% fat, 2% carbohydrate and 8% protein.

Outcomes: Unified Parkinsons Disease Rating Scale scores improved in all 5 participants. Among symptoms that improved were resting tremor, freezing, balance, gait, mood and energy level. Although 2 participants did not follow the diet as strictly as others, they were still able to achieve ketosis and improve UPDRS scores. All participants had a body mass index above 28 and lost an average of 6.1 kg during the study period.

Limitations: the assigned diet was inadequate in protein which may have improved levodopa absorption making it difficult to determine if the observed improvements were due to this or due to the effects of the diet. In addition, there was no control group, a very small sample size was followed for a short duration and the potential of a placebo effect must be kept in mind when interpreting these outcomes.

Ketogenic Diet Dramatically Improves Parkinsons Disease

Ask any neurologist how Parkinsons disease is treated, and youre sure to get a long list of medications. Truth is, none of the medications actually treats the disease. The medications that are used are clearly effective, but only focus on the management of symptoms, not the underlying disease.

It turns out that Parkinsons disease is characterized by failure of the mitochondria to make energy, and this occurs in a very specific part of the brain. That said, researchers decided way back in 2005 to explore the possibility of improving mitochondrial function by placing patients on the ketogenic diet.

Their results were phenomenal, to say the least. The study only included five individuals and doesnt appear to have gained much traction in the world of neurology. Im hoping this changes moving forward.

Am I A Candidate For The Ketogenic Diet

While the short answer is yes for the majority of people consuming a western diet, we urge you to consult your general practitioner prior to making the switch to Keto. The Charlie Foundation will provide you with the information and tools necessary to adopt the diet, and partnering with your doctor during this process will ensure the most therapeutic outcome. We also suggest that you connect with a diet professional who can help you form a plan in collaboration with your doctor, who may be less familiar with the diet.

What About Side Effects On The Keto Diet

Information About the Ketogenic Diet

Its important to note that the keto diet can have side effects. The most common include nausea, vomiting, headache, fatigue, dizziness, insomnia, difficulty in exercise tolerance and constipation. These side effects usually resolve in a few days to a few weeks. Ensuring adequate fluid and electrolyte intake can help counter some of these side effects.

Nutritional ketosis is considered quite safe as ketones are produced in small concentrations. It greatly differs from ketoacidosis which is a life-threatening condition resulting from dangerously high levels of ketones and blood sugars. Ketoacidosis mostly occurs in people with type 1 diabetes whose bodies do not produce any insulin. It can also occur in individuals with type 2 diabetes who have little or no insulin production. Several things can lead to ketoacidosis including illness, improper diet or not taking an adequate dose of insulin.

Food Aversions To Popular Keto Foods

Some individuals with Parkinsons Disease have also reported that they have developed specific food aversions to proteins such as meats, dairy, and eggs. This could make the selection of foods a little bit trickier. Sometimes a change in the way that the protein is cooked has been shown to help with this. However, if changing how the food is prepared doesnt work, you can find other keto-friendly suggestions in our guide to the vegan ketogenic diet.

Effects On Energy Metabolism

As noted above, ketone bodies, including -hydroxybutyrate, that are produced during consumption of the ketogenic diet may serve as an alternative source of energy in states of metabolic stress, thus contributing to the neuroprotective activity of the diet. In fact, -hydroxybutyrate may provide a more efficient source of energy for brain per unit oxygen than glucose . Recently, using microarrays to define patterns of gene expression, made the remarkable discovery that the ketogenic diet causes a coordinated upregulation of hippocampal genes encoding energy metabolism and mitochondrial enzymes. Electron micrographs from the dentate/hilar region of the hippocampus showed a 46% increase in mitochondrial profiles in rats fed the ketogenic diet. Thus, the ketogenic diet appears to stimulate mitochondrial biogenesis. Moreover, there was a greater phosphocreatine : creatine ratio in the hippocampal tissue, indicating an increase in cellular energy reserves, as expected from the greater abundance of mitochondria. In sum, during consumption of the ketogenic diet, two factors may contribute to the ability of neurons to resist metabolic stress: a larger mitochondrial load and a more energy-efficient fuel. In combination, these factors may account for the enhanced ability of neurons to withstand metabolic challenges of a degree that would ordinarily exhaust the resilience of the neurons and result in cellular demise.

What Is The Ketogenic Diet

The Ketogenic diet uses fat as the largest nutritional component of the diet. High amounts of fat will break down into ketones in the bloodstream, and your body will then be able to use ketones as a fuel source. Limiting carbohydrates and sugar intake will minimize the glucose in the blood, leaving cells with no choice but to use ketones as fuel. However, there is one crucial element to the ketogenic diet that is often missed.

What is imperative about the ketogenic diet is that the purpose is to produce ketones. When anyone implements the ketogenic diet, blood ketone levels must be checked to ensure the body is in ketosis. If blood ketones are not measured, the full benefit of the ketogenic diet may not occur.

How The Ketogenic Diet Changes Brains With Parkinsons Disease

Keto Diet & Parkinson’s Disease with William Curtis

One of the first studies that provided validity to the idea that the ketogenic diet can help with Parkinsons disease was a study conducted on mice treated with MPTP. MPTP is a toxin that specifically targets the neurons involved in Parkinsons disease, leading to neuronal damage and symptoms that mimic the disease.

To test the effects of the ketogenic diet, the scientists fed the mice with Parkinsons disease the ketogenic diet and looked at what it did to their brains. They found that the ketogenic diet was protective against the damage done by MPTP and reduced inflammation in the relevant areas of the brain.

To confirm that these positive effects are transferable to humans, the scientists decided to put the diet to the test in Parkinsons disease patients. In this study, seven patients with the disease volunteered to follow a ketogenic diet for 28 days at home.

Only 5 out of the 7 completed the 28 days, but the results showed a positive impact on many common Parkinsons disease symptoms. This included a reduction in resting tremors and rigidity and improved balance, gait, mood, and energy levels.

Although this is a very promising study, it is too small of a sample size to assume that everyone affected by the disease will get the same benefits.

However, the ketone levels didnt seem to matter as long as the subjects were in ketosis.

How Long Should I Be On The Diet

We at the Charlie Foundation believe that a 3-month commitment to the diet is a minimum commitment to allow your body to fully acclimate to the new fat based fuel source. Since most people following a western diet are not proficient at metabolizing fat optimally, this period allows the body time to become fat-adapted, utilizing dietary fat efficiently and effectively. There are a variety of nutritional plans that will enable a ketogenic lifestyle, and flexibility is one of the hallmarks of the diet that make it easy to adopt as a life-long tool to enhance your health. Our nutritionists can help figure out both the short and long-term options best suited for you and your lifestyle.

The Keto Diet’s Connection To Parkinsons

Researchers are also exploring the relationship between so-called ketogenic diets and Parkinsons disease. Simply put, a Keto Diet emphasizes fat, along with a moderate amount of protein, with very few carbohydrates. The diet makes us burn fats instead of carbs.

One clinical study of Parkinsons patients put low-fat, high-carb diets head-to-head with a high-fat, low carb ketogenic approach. Participants in the study were given shopping lists, menus, recipes and forms to keep track of blood glucose and ketone levels. Both groups showed improvement in both motor and non-motor symptoms. However, the ketogenic diet group scored better in symptoms like urinary issues, fatigue, pain, sleepiness and cognitive abilities. It is thought that keeping the body in ketosis might promote beneficial chemical reactions. Many researchers believe ketogenic diets are safe for Parkinsons patients for up to two months.

Types Of Ketogenic Diets

There are a variety of diets that will allow you to get into ketosis. The major differentiating factor between them all is the amount of calories that come from protein, carbs and fat, which are what we call macronutrients, or nutrients in our food that have a caloric value. The three macronutrients differ in many ways, namely, their caloric values, as well as how the body uses them. Fat is the most calorically dense macronutrient, having 9 calories per gram, compared to 4 calories per gram for both carbs and protein. In a homeostatic state, the body utilizes fat and carbs for energy production, while it uses protein to rebuild the cells of our body. While this is generally the case, an overconsumption of protein can lead the body to break down the excess protein into glucose

Controversies And Adverse Effects Of The Kd


The mechanisms of neuroprotection described above have often been studied in a single animal model and the generalizability to other sources of neuronal injury and different neuronal tissues are unknown. Notably, the effect of ketone bodies on antioxidants has been shown to differ across brain regions and exhibit age-specific effects , which may underly variations in outcomes of the KD among different studies. As noted above, high concentrations of BHB were found to induce pro-inflammatory signaling which is the opposite effect of lower concentrations because of this dose-dependent BHB effect on inflammation, it is important to measure serum and/or tissue BHB levels to properly assess the effect of the KD. Additionally, beneficial effects of the KD in animals have been shown to not always translate to a benefit in humans, for example, motor improvements were shown in rat models of PD but not patients with PD. Therefore, extrapolating the results of studies from animals to humans must always been done cautiously. Furthermore, it is important to consider that molecular mechanisms that lead to reduced inflammation and lower oxidative stress may change with longer durations of the diet, and the reported short-term mechanisms of neuroprotection may not necessarily contribute to its long-term effects.

More On Fasting And Keto For Individuals With Pd

Its slightly too early to claim that the ketogenic diet dramatically improves Parkinsons disease and Alzheimers. But this approach, as well as fasting, is quickly showing some strong potential. Since its outside the realm of drugs and medications, its a very gentle method that is gaining attention.

Both diets rely on our bodies switching to an alternate energy source ketone bodies. Keto diet for Parkinsons patients can increase ketones fourfold, whereas fasting has been shown to increase ketones by up to twentyfold.

Researchers assume that the positive effects seen in mice could be rooted in evolution. The transition from hunter-gatherer to agricultural societies meant that people no longer had to go long periods without eating. However, back then, our bodies favored those who could survive with long breaks between meals.

Our bodies are dependent on glucose as an energy source that we receive from carbohydrates in foods. It lasts for about 12 hours after we eat, and then our bodies switch to ketones. These chemicals also fuel our organs, including the brain. Higher ketone production has been linked to improved thinking, learning, and memory.

Other reasons Parkinsons and Alzheimers patients are recommended fasting are:

Study Tests Ketogenic Diet For Parkinsons

Can a special high-fat diet help people with Parkinsons disease?

Although researchers havent found a cure for the degenerative disease, theyve found ways to slow its progression from medication to exercise such as boxing.

This year, scientists at the National Institute of Neurological Disorders and Stroke are studying the effects of a specific diet on Parkinsons patients.

Its called a ketogenic diet a high-fat, low-carbohydrate diet in which the body, deprived of carbohydrates, is forced to burn fat. While people on the diet must avoid pasta, bread and sugar, they can eat plenty of butter, cream and nuts.

Its a diet that has less carbohydrates and greater fats than a typical American diet, said Dr. Debra Ehrlich, Chief, NIH Parkinsons Disease Clinic and the studys principal investigator.

Were trying to look at using the ketogenic diet in a population of patients with Parkinsons disease, Ehrlich said. Several previous studies of the ketogenic diet in Parkinsons patients have shown either improved motor functioning or improved memory or cognition.

Our first objective is to see if its feasible and well tolerated in patients with Parkinsons. Our second objective is to see if theres any improvement in Parkinsons symptoms, such as cognition, mobility and motor function.

Ketogenic Diet In Parkinsons Disease

by Jo Mak | 4 May, 2020 | Dietetics

A ketogenic diet means high-fat and very low-Carbohydrate diet. It is a type of metabolic therapy which means the body is using mainly ketones as an energy source instead of glucose. The aims of metabolic therapy are to optimize neuron metabolism, growth and repair, and protect neurons.

A pilot randomized controlled trial in 2018 had compared the effects of a low-fat diet and ketogenic diet on Parkinsons Disease. The low-fat diet consisted of vegetables, meats, whole grains and fruits with ~25% calorie intake from fat. Whereas the Ketogenic diet consisted of vegetables, meats, eggs, cheese, oils and nuts with ~80% calorie intake from fat. The results showed that both diets improved the motor symptoms of Parkinsons Disease. Interestingly, the ketogenic diet also showed significant improvements on non-motor symptoms of Parkinsons Disease, e.g. Urinary problems, pain, tiredness, cognitive impairments and daytime sleepiness. In conclusion, the ketogenic diet is feasible and safe for Parkinsons Disease and it showed greater improvements in both motor and non-motor symptoms in Parkinsons.

The Ketogenic Diet, also referred to as the ketosis diet, or Keto for short, is a way of eating that mimics the effects of fasting. By consuming a diet rich in quality fats, adequate in protein, and low in net carbohydrates , the bodys metabolism begins to utilize fat as its main source of fuel, rather than carbs. This shift has profound effects on metabolism for both the sick and healthy alike. The diet shows promise for improving or reversing many neurological conditions and metabolic disorders. For the healthy, the diet represents a tool for preventing chronic disease, as well as optimizing cognition and body composition .

Primary And Secondary Outcomes

Primary outcomes were within and betweengroup changes in MDSUPDRS Parts 1 to 4 from the mean of the two baseline clinical visits to week 8 after commencing the diet intervention. Secondary outcomes were within and betweengroup changes in metabolic parameters, including weight, BMI, HbA1C, triglycerides, HDL, LDL, total cholesterol, urate, and CRP.
