Frequent exercise depletes glycogen stores, causing your body to turn to fat for energy; this means that regular exercise can help you get into ketosis faster. Some people experience a reduced capacity for exercise upon starting keto; in this case, engaging in longer durations of low-intensity activity, such as walking, cycling, or swimming, can help you get into ketosis without causing undue fatigue.
I want to be very clear, though, that I don’t believe claims that are made on some websites that the ketogenic diet beats chemotherapy for all cancer treatment. There’s simply no research to support that. I don’t know where those websites are getting that idea, and there’s a lot of snake oil when it comes to cancer treatment out there. It’s a really vulnerable population. Someone who’s diagnosed with cancer, particularly a late-stage cancer that might be terminal, understandably we often feel pretty desperate and might not have the capacity at that moment in time to go through the proper vetting process to make sure that some of the more alternative therapies that are suggested are legitimate, and so you see a lot of wacky stuff recommended for cancer treatment.
When I was six years old, I was diagnosed with temporal lobe, partial-complex epilepsy. Over the years, I have seen multiple doctors and neurologists and I have been on every medication created to treat epilepsy, but I still continued to have seizures about every 6-8 weeks. For the most part, I have been able to lead a normal life achieving my college degree, getting married and having two happy, healthy kids but every time I had a seizure it was a cruel reminder that I was not everything I needed to be for my family. Many times after a seizure, I would be unable to work and care for them for days at a time.
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
I am trying to get back into keto. I did it before and I was so happy when I lost 10lbs (I did the keto for a month). I am ready to go back to this lifestyle. All this information is very helpful, I have written it all down so it can be easier for me to remember what is allowed and what is not. Looking forward to get back on this keto journey. Thank you for all the great info.
On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids. Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.
The ketogenic diet may seem like the Jekyll to the Hyde-like low-fat craze of the 1990s. The bulk of current research finds that the middle ground between the two extremes is more beneficial for overall health. Make it easy for yourself: Eat at least two servings a week of fatty fish (salmon, sardines, mackerel) and cook with a variety of quality fats (olive oil, canola oil, avocado oil) throughout the week.
Several studies have shown that the MAD, besides being more palatable, is as effective as the KD in the treatment of drug-resistant epilepsy in children (Miranda et al., 2011; Martin et al., 2016). A study performed using 20 children receiving 10 g of carbohydrates daily showed that 65% of the children had a >50% seizure reduction, 35% of the children had >90% improvement, and four children were seizure-free at 6 months (Kossoff et al., 2006). In a study in South Korea, 36% of 14 children treated with the MAD showed improvement of >50% in seizures and 12% were seizure-free (Kang et al., 2007). A recent meta-analysis performed using 70 studies concluded that the MAD and classical KD do not differ in reduction of seizure frequency at month 3 and month 6, with ≥50% and ≥90% reductions, respectively (Rezaei et al., 2017). A retrospective study showed >50% of seizure reduction in 65% of the 10 children who remained on the diet for up to 6 months, and 20% of them were seizure-free (Park et al., 2018).
A ketogenic diet typically leads to a broad range of improvements in blood lipids as well as other cardiovascular risk factors such as blood pressure and inflammation. However, the changes we see in total and LDL cholesterol levels are much less predictable than the changes in other blood lipids such as triglycerides and HDL cholesterol. For some people, calculated LDL cholesterol goes down, and for others it goes up, sometimes quite a bit. This tendency for some people to see an increase in their LDL cholesterol has been a focus of research over the last decade because the question remains – “What, if anything, does this tell us when assessing one’s risk of heart disease?”
However, this doesn't happen in every case or even most cases. In fact, many people see little to no increase in their LDL cholesterol while experiencing beneficial changes in other markers, such as an increase in HDL cholesterol and a decrease in triglycerides, blood sugar, and insulin levels – all of which are associated with reduced risk of CVD.
Differences between ketosis and ketoacidosis Ketosis and ketoacidosis both involve increased levels of ketones in the body. However, they are not the same thing. Nutritional ketosis is the aim of the ketogenic diet, and it is generally safe, whereas ketoacidosis is a complication of type 1 diabetes that can be life-threatening. Learn more here. Read now
Similarly, in a 2015 study, mice receiving a combination of hyperbaric oxygen and dietary ketone supplementation showed a clear reduction in tumor growth rate and metastasis.20 Also, these mice lived twice as long as control animals. Based on these results, the study authors state that further investigation into the effectiveness of this combination therapy as a potential treatment for late-stage metastatic cancers is urgently required.
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. 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.
I wanted to put it out there that I made this meal plan specifically with women in mind. I took an average of about 150 women and what their macros were. The end result was 1600 calories – broken down into 136g of fat, 74g of protein, and 20g net carbs a day. This is all built around a sedentary lifestyle, like most of us live. If you need to increase or decrease calories, you will need to do that on your own terms.
When you eat less than 50 grams of carbs a day, your body eventually runs out of fuel (blood sugar) it can use quickly. This typically takes 3 to 4 days. Then you’ll start to break down protein and fat for energy, which can make you lose weight. This is called ketosis. It's important to note that the ketogenic diet is a short term diet that's focussed on weight loss rather than the pursuit of health benefits.
If you need to eat more or fewer calories per day, you can adjust accordingly by simply taking out or adding a bit more of the ingredients already included in a recipe. For example, adding/removing a tablespoon of olive oil or butter will add/remove about 100 calories. If you like or dislike certain recipes, feel free to shift things around. Make sure to keep an eye on the calories so you’re still falling within an acceptable range of your daily goal.
While KD and MAD have demonstrated efficacy in reducing the extent and degree of seizures in epileptic patients, the dietary approaches have been tied to risk of adverse events in both adults and children, although most are treatable and are nearly all preventable. Adverse effects include constipation, low blood sugar, and gastrointestinal reflux.5,6 Other side effects, such as kidney stones and high cholesterol, can often be improved with supplements or dietary changes.1 These also tend to improve over the long term. Kossoff and colleagues found that both total cholesterol and LDL cholesterol normalized within a year of treatment after initial increases during the first three months of MAD.5
Some practitioners have raised the concern that long-term adherence to a ketogenic diet may shift the composition of the microbiota (the beneficial microbes that live in our bodies) in an undesirable direction and may even encourage the overgrowth of ‘bad’ bacteria. These beneficial bacteria feed on prebiotics (such as fiber and resistant starch), both of which are likely to be low in a low-carbohydrate ketogenic diet. Without prebiotics, beneficial bacteria are not able to produce substances like butyrate and other short chain fatty acids that keep the intestinal cells healthy, and long-term disruption of the microbiota can lead to a host of health problems throughout the body. 57 58
While a ketogenic diet (or the Atkins diet done intelligently) can be healthy and create results, too many people make mistakes that can derail their long-term progress on these plans. In my practice, where I work with patients on gut-healing (you can get my free kickstart guide to gut-healing here), I’ve found these seven strategies will help you design and maintain a healthier ketogenic diet plan:
Dr. Gonzalez and his colleague Dr. Linda Isaacs MD have had remarkable success treating cancer patients with a non-toxic nutritional protocol that incorporates some of the principles of the late Dr. Max Gerson MD along with the late Dr. William Donald Kelley’s protocol which includes high doses of pancreatic enzymes and individualized diets depending on body type and cancer type. I have huge respect for them, not because of their theories, but because they are getting RESULTS, including reversing “incurable” stage four cancers. Two volumes documenting 112 of their successful case studies can be found here.
Recent studies show that low-carb diets such as keto are more effective at raising good (HDL) cholesterol than low-fat diets [1, 2]. However, there are also studies showing that keto can increase total cholesterol (HDL and LDL) . On the other hand, low-carb, high-fat diets also decrease LDL particle concentration (LDL-P), increase the size of LDL cholesterol and decrease the amount of harmful VLDL cholesterol in the blood , all of which have a positive effect on cardiovascular fitness.
Mitochondria generate reactive oxygen species (ROS) during their metabolic activities. In normal cells, the production of ROS and their elimination by antioxidants are kept in balance.10 Intriguingly, a higher incidence of errors, or mutations, in mitochondrial DNA have been observed in many human cancers, likely as a result of uncontrolled ROS production and oxidative stress.11
Jimmy Moore: I did not say that. You see my Instagram account, you know how much I hate processed boxed food. The mono unsaturated fats are avocados, avocado oil, 100% olive oil … that’s key too, make sure your getting olive oil that you know is 100% olive oil, because they can sneak in some of those omega-six facts into there and not tell anybody. That screws people up trying to avoid those. Of course, nuts have mono unsaturated fats as well. You can get a well rounded amount of fat from varying sources and that is really what’s going to help you in controlling your blood sugar, controlling your cholesterol, and controlling your inflammation.
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.
When in the hospital, glucose levels are checked several times daily and the patient is monitored for signs of symptomatic ketosis (which can be treated with a small quantity of orange juice). Lack of energy and lethargy are common, but disappear within two weeks. The parents attend classes over the first three full days, which cover nutrition, managing the diet, preparing meals, avoiding sugar, and handling illness. The level of parental education and commitment required is higher than with medication.
Otto Warburg was a leading cell biologist who led to the discovery that cancer cells are unable to flourish using energy produced from cellular respiration, but instead from glucose fermentation. Dr. Thomas Seyfried and other cancer researchers agree, and have further discovered that cancer cells are also fueled from the fermentation of the amino acid glutamine.
Bulk buy and cook. If you’re someone who doesn’t like to spend a lot of time in the kitchen, this is the best of both worlds. Buying your food at bulk (specifically from wholesalers) can reduce the cost per pound tremendously. Plus, you can make ahead food (bulk cook chicken thighs for pre-made meat, or cook entire meals) that are used as leftovers, so you spend less time cooking.
In addition to neuroblastoma, various researchers have investigated the efficacy of KDs as an adjuvant therapy for other types of cancer. The strongest evidence (> 3 studies) for a tumor-suppressing effect has been reported for glioblastoma, whereas little or no benefit was found for two other brain tumors (astrocytoma and medulloblastoma). Good evidence (2 - 3 studies) is available for prostate, colon, pancreatic and lung cancer ; neuroblastoma also falls into this category (Figure 1). Some of those studies report a tumor-suppressing effect of KD alone and/or in combination with classic therapy and/or caloric restriction. One study on prostate cancer applied the KD in a preventive, instead of a therapeutic, study setting. Only limited evidence (1 study) supports the anti-tumor effect of an unrestricted KD on breast, stomach, and liver cancer.
HDL is still low and stuck on 45 even after hoping strongly with more healthy saturated fats organic bone broth from lamb bones, etc. LDL way up 170 and triglycerides a a record high of 170, Non HDL choleseterol at 203. Kinda surprizd I cannot more that HDL number aftyer all the keto stuff. And unsure why the LDL has exploded since stress has always been with me these last 9 years.
Kelsey: Hi, Chris, I was just wondering about your thoughts on the ketogenic diet as an approach to cancer prevention and therapy. I just read something about how cancer cells can only thrive on glucose, and in its absence we can prevent cancer potentially. So I was wondering if you could discuss this in a podcast. I think that would be great. Thank you.
In this article, I have presented a number of cases, seven to be exact, four from Kelley’s files and three from my own practice. The four Kelley cases include the 31-year survivor of metastatic pancreatic cancer confirmed at Mayo, the 34-year survivor of stage IV endometrial cancer, the five-year survivor of aggressive brain cancer, and the 11-year survivor of advanced, aggressive multiple myeloma.
“But if you’re a young and healthy adult, I have no safety concerns about removing carbs,” he adds. “It’s really not a radical concept.” You may experience some short-term issues like bad breath, constipation and flu-like symptoms. (Drinking lots of water can help.) But the lasting benefits could range from reduced hunger and increased energy to weight loss. Some preliminary research even hints at memory improvements.
Everyone talks about upping their fats… I do not think that is the key to sweeping LDL out of the system. Upping cruciferous fiberous veggies… the fiber, vitamins and minerals contained in veggies bind with the LDL and move it on out. You would have to eat literally a truck load to make any serious dent in your daily carb allowance since most are very low net carb anyways.
Yes, they're technically a fruit, but we think olives deserve a shout-out all of their own, since they're also a great source of healthy fats and are one of a few keto-approved packaged foods. Plus, they're a great source of antioxidants, will satisfy your craving for something salty, and are blissfully low-carb. “About a palm's worth only has 3 grams of net carbs,” Sarah Jadin, RD, told Health in a previous interview.
Typically known as the “bad cholesterol” to its healthy counterpart HDL cholesterol, increased levels of LDL cholesterol are associated with an increased risk of cardiovascular diseases (CVD).  Some studies show a strong correlation between LDL cholesterol and the risk of cardiovascular diseases in both men and women.  Evidence also suggests that decreasing blood levels of LDL-C reduces the risk of CVD. 
Recently, many of my patients have been asking about a ketogenic diet. Is a ketogenic diet safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss.
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.)
In fact, ketogenic diets have been used for nearly a century to treat seizures, says Gary Yellen, a professor or neurobiology at Harvard Medical School. “It dates back to studies from the 1920s that found this kind of diet was like a sustainable form of fasting, which we’ve known, supposedly since antiquity, to be beneficial for epilepsy,” he says.
After reading Grain Brain by Dr. Perlmutter, I called his office and was able to meet with him in person. When he read my past medical history he confidently prescribed the Ketogenic diet for me and his nutritionist worked to develop just the right set-up for my BMI. It seemed like a big change at first but really it has been much easier than I originally thought it would be. Now, after being on the diet, along with probiotics and supplements, I can say that I have been seizure free for over 4 months for the first time in over 20 years! My whole world is changing! I can work on getting my driver’s license! I can be what my family needs me to be! I believe God has used the Ketogenic diet to heal my epilepsy and I want to make sure everyone out there who is suffering from seizures has the opportunity to know about and try this amazing, risk-free treatment!
Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese.
