Ketogenic Diet and Cancer

Ketogenic Diet and Cancer

by Kelley Herring on March 18, 2015

Looking for information on a ketogenic diet and cancer? You’ve come to the right place.

A recent report from the World Health Organization states that the number of cancer cases worldwide is expected to surge by 57 percent over the next twenty years.

For many, this will mean painful, expensive (and potentially deadly) treatments with chemotherapy and radiation. On the other hand, many others will choose a more natural approach to treat and prevent cancer… one that is meant to boost the immune system, curtail the proliferation of cancerous cells, and starve those cells of the very fuel they need to grow.

And one of the most effective natural approaches for doing this is the ketogenic diet. It is certainly not the only thing that should be included in a cancer-fighting protocol, but science has proven that it can be a very important part of one.

The Ketogenic Diet and Cancer: Natural, Effective “Metabolic Therapy”

The ketogenic diet is a very low carb diet that is moderate in protein and high in fat. It is well known that the cells in your body are normally fueled by glucose (the form of sugar present in the blood). But when glucose is not available, cells derive their energy from ketones – a byproduct of fat breakdown.

And if you are concerned about cancer this is a very good thing…

You see, cancer cells work differently than normal cells. And while they thrive on glucose, they are unable to make the switch to ketones. Without glucose as a source of fuel, cancer cells begin to die off. Over time, tumors shrink and the diagnosis of “cancer” can disappear. Dr. Dominic D’Agostino, metabolic therapy researcher at the University of South Florida says:

“Your normal cells have the metabolic flexibility to adapt from using glucose to using ketone bodies. But cancer cells lack this metabolic flexibility. So we can exploit that.”

In fact, preliminary studies have shown the ketogenic diet to be so effective at resolving a number of different types of cancers (including some in the advanced stages) that it is being called “metabolic therapy.”

Researchers at the University of South Florida found that removing carbohydrates from lab mice with aggressive cancer increased their recovery. The ketogenic diet was also shown to work better than traditional chemotherapy (and, of course, without the horrible side effects).

Another study at Johns Hopkins found that people with brain tumors have a significantly lower survival rate when they have higher blood sugar levels. This provides additional support for the role of a ketogenic diet in the prevention and treatment of cancer.

Starve Cancer with a Ketogenic Diet

Tips for Following a Ketogenic Diet

With cancer on the rise, the ketogenic diet is providing a safe, natural means of prevention and recovery for many people. And while each one of us is unique, with regards to the macronutrient ratios required to reach ketosis, a general guideline is to keep your carbohydrate consumption limited to 50 grams per day. The majority of calories should come from healthy fats and moderate amounts of protein.

Here are some quick meal ideas for a ketogenic diet:

  • Breakfast: Pastured eggs cooked in grass-fed butter, pastured pork sausage and avocado. You could also supplement with a tablespoon of coconut oil, avocado oil, fish oil or MCT oil for an added boost of healthy fats.
  • Lunch: Wild salmon over a large organic green salad with Kalamata olives and extra virgin olive oil vinaigrette. Pastured lamb burgers with mint gremolata, olives and greens (with oil or duck fat) might be another option.
  • Snack: Grass-fed pemmican, Brazil nuts, macadamia nuts or canned mackerel… plus another tablespoon of your favorite healthy fat.
  • Dinner: Free-range roasted duck legs (or duck confit) over mashed cauliflower with grass fed butter and a green salad with olive or avocado oil. Another option: Grass-fed ribeye steak with a generous helping of basil pesto and steamed broccoli. Another tablespoon of your favorite healthy fat before bed.

In addition to the ideas presented above, make sure you are getting at least 8-10 servings of very low-carb, phytonutrient-rich veggies (unlimited amounts of organic kale, organic spinach, organic beet greens, with some organic cucumber, organic zucchini, organic peppers), low-sugar berries (half a cup of organic raspberries or organic blackberries) and alkalizing lemon. A convenient way to boost your intake of these powerful foods is in a whole food juice.

As research continues to mount that cancer is largely a disease of the metabolism, we have more opportunities to treat it with the safe, natural diet enjoyed by our ancestors. As always, talk with your health practitioner before making any dietary changes.

Have you tried a ketogenic diet for cancer, weight loss or any other reason?  If so, what was your experience?

  1. April B L'Heureux says:

    Hello Kelley, et. al. I am very interested in the Ketogenic diet for weight loss, have you any information on this ? Seems like a natural combo….??
    Is the Atkins phase-one this type of eating?

    • Kelley Herring says:

      Hi April!
      Thanks so much for stopping by.

      The ketogenic diet is very popular and effective for weight loss. I will be posting more on the benefits of ketosis soon.

      As for Atkins, while phase one is ketogenic, his program advocates artificial sweeteners and processed dairy products which we avoid here at Healing Gourmet.

      Please stay tuned!

      Be Well,

    I am a holistic nutritional with 15 years experience. My main focus is helping people with cancer. I have been reading and researching all sorts of holistic therapies, nutrients ect, and I have been able to help even late stage clients to not just survive cancer but even thrive.
    I can however clearly tell that you don’t understand cancer at all, and truthfully, you really should not be giving advice on this subject.
    Where you are right suggesting a low carb diet, your meal suggestions are a nutritional nightmare! You will be sending people to the grave by having them eat loads of eggs and meat! Meat is very acidifying and promotes inflammation (esp pork), not to mention the horrors it does to the digestive tract. Besides, it is putting straign on the liver and creates a perfect environment for cancer cells to thrive. Even eggs promote hormonal cancer (breast, ovarian, prostate), (please do your own research) as they have a strong estrogenic influence on the body – the last thing you want when battling cancer. The right approach is a diet very strong in greens, veggies, some fruits, nuts and seeds.

    • You stand corrected – I am a living success story, having beat stage 2 breast cancer with diet only. I was a very “educated” low fat vegan and began eating LOTS of meat and eggs and loads of fat in the form of bacon fat, coconut oil, grass fed butter and avocados. I got rid of ALL grains (whole grains especially) and ate only low sugar veggies. Swapped all drinks out for homemade cucumber-lemon infused water. BOOM. My full healing came about within four months and 16 days. No chemo. So I respectfully urge you, Antje, to open your mind and eyes to the latest RESULTS many – like myself – are experiencing. Thank goodness I did not read a “suggestion” like yours before I embarked on this way of eating..I may not have been here today. Much love and healing to all!!

      • Kelley Herring says:

        Hello Josie!
        My heart just sang when I read your reply.

        Breaking dietary dogmas and taking a route other than conventional cut/poison/burn takes a heck of a lot of courage. It is people like YOU who are living proof that inspire others to heal in the same way.

        Thank you for sharing your awesome story with us, Josie. And kudos for being the author of your own health!

        Be Well,

      • Hi Kelley

        Please could you share some recipes with me as by sister, brother-in-law and 26 year old nephew with a brain tumour are coming to stay with me this weekend. They are all following a keto, cancer, low carb diet and I’m a bit lost and don’t want to hassle them.

        Or ideas – what are low carb veg?
        How to make your cucumber and lemon water
        and what to do with coconut oil.

        Please don’t publish my name to this as my family are going through enough and I don’t want them identified, feel free to change my name though.

        Kind regards


        • Kelley Herring says:

          Hi Pat!
          Thank you for your question. The keto diet is actually very easy to follow and very satisfying as it is primarily fat.

          Low carb veggies are above ground vegetables – including any kind of greens (spinach, arugula, etc.), cabbage, cauliflower, kale, Brussels sprouts, broccoli, asparagus, mushrooms, celery and peppers.

          For menus, the key is to focus on these ultra low-carb veggies and healthy fat sources… and not go overboard on the protein. (This is because protein can be converted to blood sugar by a process called gluconeogenesis). Here are a few of my favorite keto meals:

          Buttery Kale Baked Saucy Eggs
          Sausage + Avocado
          Pan-Seared Steak with Mushrooms, Bone Marrow Butter Cauliflower Mashers & Asparagus
          Paleo Wild Salmon Cakes with Remoulade over Arugula
          Red Curry Chicken with Zoodles & Cashews
          Shrimp Louie Salad
          Keto Meatball Subs with Italian-Style Steamed Broccolini (use my Keto Rolls –
          Cobb Salad
          Slow Cooker Vinegar-Thyme Chicken with Olives, Roasted Brussels Sprouts with Mushrooms, Bacon and Shallots

          Some of these recipes are on this site; many will be available with my new meal planning program. Also, Martina of KetoDietApp has some amazingly delicious and simple recipes you should definitely check out:

          Sending my best wishes for a speedy recovery to your nephew.

          Be Well,

        • hello, i would like to recommend for supplements and cleanses that in part, can heal cancer. sorry if this isn’t allowed, in life and death situations i just think the more GOOD information, the better the chances of making it.

    • Kelley Herring says:

      Hello Antje,
      So, you think eggs and meats and other animal products are detrimental to cancer?

      While I do wholeheartedly believe that conventionally-raised animal products are not healthy for anyone (especially those with cancer), animal products raised right provide a plethora of essential “zoonutrients” that promote cellular health and fight cancer including:

      Choline – Most plant foods are devoid in choline – a nutrient that promotes detoxification, prevents fatty liver and promotes healthy genetic expression via methylation. Eggs and liver are the best source of choline and only 10% of Americans get adequate amounts of this cancer-fighting nutrient. Learn more here:

      Vitamin B12 – The ONLY source of B12 is animal foods. Vitamin B12 is one of three key methylating agents (which also includes B6 and folate). Have you heard of methylation? It is a vital process at the genetic level that helps to repair damaged DNA and ensure we are making healthy copies of DNA. Healthy DNA means healthy cells which means reduced risk of cancer.

      Selenium – Due to poor soil, plant foods (except Brazil nuts) are very poor sources of selenium. Why is selenium important? It is an antioxidant micronutrient that is needed to produce our “master antioxidant and detoxifier” – glutatione. The best sources are animal foods – pastured lamb, grass-fed beef, pastured chicken and turkey, wild salmon, shrimp and scallops are all excellent sources.

      Conjugated Linoleic Acid (CLA) – This healthy fat – found only in meat and milk products from animals grazing on grass- has been found to block all three stages of cancer (initiation, promotion, metastasis). In lab studies it has been found effective against a variety of cancers – skin, breast, lung, colon and prostate. And women in Finland who got the most CLA in their diet experienced a 60% reduction in breast cancer compared with those getting the least

      This list is by no means exhaustive – there’s EPA/DHA (the superior omega 3 fats, only from animal origin), zinc, vitamin B6 and more.

      I believe the keys to cancer prevention are minimizing toxins and supporting healthy detoxification, keeping insulin levels low with a low glycemic diet, preparing foods to maximize benefits and minimize harmful byproducts, and optimizing the nutrients that are known to promote cellular health. As illustrated above, many of the most powerful cancer-fighters come from animals – whether we like it or not.

      As for doing my research, cancer is a topic that I am very passionate about. In 2005, I served as Editor in Chief for Healing Gourmet’s first book – Eat to Fight Cancer (McGraw-Hill) and have read more than 10,000 studies on cancer alone. I’m a big proponent of phytonutrients, but I do not believe they are enough on their own to provide our bodies – specifically, our ancestrally-designed omnivorous genetics – with the nutrients we need to thrive.

      As for your research, can you point me in the direction of your references? You didn’t cite a single one.

      Honestly I read these menu. I almost puked. I am a vegetarian for almost 6 months . Feel better than ever at 55 yrs old and a BC survivor -5 yrs this march. I can’t tolerate meat and dairy after all the chemo and radiation. Being a stage 1 with a positive her2 I was ‘the needle in the haystack’ . I am a swimmer, cyclist, runner and hiker. Stronger and more energy than a 20 yr. Old. Eating your diet would kill people. All that cholestral, fat, etc. You should re-evaluted your so called healthy diet. Yuk on you…

      • Kelley Herring says:

        The article above is based on research that is helping many people to overcome cancer. I’m not sure why reporting the benefits of metabolic therapy and the cutting-edge research conducted at the University of Florida earns me a “yuk on you”.

        It is well-known that cancer cells thrive on glucose, and starving them of this substance causes them to die off… naturally.

        I am supportive of any natural means to rid the body of this disease, and believe that each individual, when faced with a diagnosis of cancer, has a tough decision to make. That decision is personal, and educated, inquisitive people tend to question the “cut poison burn” methods that cause obliteration of tissues, organs (like your digestive system, as you mentioned) and the very immune system that protects us from cancer.

        Healthy fat and cholesterol don’t kill people or contribute to cancer…but radiation and chemo sure do.


    • Meat is scientifically proven to be carcinogenic. That said, if people make the switch from a High carb diet to one without carbs they Can benefit and some people do fine with this much meat. Personally, I would never want to eat that much meat

      • Kelley Herring says:

        Hi Bonnie,
        Meat cooked at high temperatures can cause carcinogenic compounds to form in meat (like heterocyclic amines), and yes, even fish produced with hormones and antibiotics can influence cancer risk… but meat in and of itself is not carcinogenic. As we have written many times on this site, it is vital to take into account the source and the method of preparation when considering the health of any food. Berries and spinach produced conventionally contain carcinogens (and lots of them!), but I would never say that berries and spinach cause cancer. Cancer is a multifaceted process and there is much to be taken into account. Similarly, when a population study states that red meat causes cancer, that study is not isolating meat alone, but rather evaluating a pattern of eating. And as we all know, most Americans eat red meat with a side of fries and a large (diet) soda. Please, Bonnie. Show me your science.

        • Read “The China Study” by T Colin Campbell. Very compelling research. However, I don’t think any one diet is right for everyone. Ketogenic may works for some people, but the Gerson approach, which is completely vegetarian, has also helped many to heal their cancer. Eating animal products 3 times per day would be deadly for some, and others would not do well with Gerson. Everyone has to find what is right for their body.

          • Kelley Herring says:

            You mean, the China Study which has been discredited by many including Chris Kresser and Chris Masterjohn… The China Study that throws out entire subsets of people like those of Tuoli China who ate 45% of their diet as fat, double the animal protein of Americans (about 134 g/day), who experienced extremely low rates of cancer (and heart disease, too)? I agree that cancer treatment should be individualized, but it should also be intelligent… and not based on dogma or cherry-picked studies.

  3. Rose paduch says:

    I have a question I purchased all your baking books, in the better breakfast you call for Native forest coconut milk. However you do not specify if unsweetened or sweeter. Low fat or whole. Please advise. Thank you

    • Kelley Herring says:

      Hi Rose!
      Thank you for your comment and recent purchase. I hope you enjoy all of the recipes.

      I do not believe Native Forest Coconut Milk comes in “sweetened” only original or light. I always opt for original (full fat) as the light version is just watered down and costs about the same. Also, the fats in coconut are very healthy and have a wide variety of benefits.

      Be Well,

  4. I’d love more ketogenic meal plans and a complete list of keto foods.

    • Kelley Herring says:

      Hi Suzanne,
      It is great to hear from you!

      Thanks so much for your comment. We have received lots of requests for this, so I will be doing a follow up on keto.

      Be Well!

  5. I think everyone should read these articles on diets before committing to any of them. There are many articles and diet guru’s out there – but who to believe. I tend to take them all in and make my own informed decision. Some great articles by a very knowledgeable person here:

  6. A ketogenic diet helped my daughter and I lose the weight that was bogging us down. In the beginning it was very hard to get over our fear of fats. After losing 60 pounds (almost effortlessly after the first few difficult weeks) at 50 years of age with great blood work after 10 months on the diet, I don’t think I’ll ever go back to my old diet of grains and empty carbs.

    Keep spreading the word Kelley! More people need to hear about ketosis!


    • Kelley Herring says:

      Hi Laura,
      Great to hear from you.

      I think many people do still have that fear of fat, as well as misconceptions about the dangers of ketosis. Thank you for sharing your inspirational story with us to help others on their journey.

      Be Well,

    • Hi Laura,
      congratulations on your success!
      Will you PLEASE share what your regimen of eating Ketogenic looked like with some specificity? For instance, did you count calories as well as eating high fat?
      I have asked Kelley but still waiting for concrete information.

      • Kelley Herring says:

        Hi Avril,
        I provided as “concrete” info as I could… but ketogenic diets are not like other diets. Each individual must determine the right range of macronutrients to achieve ketosis – a PHYSICAL, MEASURABLE state that is unique to an individual’s metabolism. It’s not just eating high fat – it is also eating low to moderate in protein and very low in carbs. But again, the macros required to achieve ketosis will be unique to YOU and must be determined with trial and error and measuring (keto sticks).

      • Hi Avril, thanks for asking. We absolutely love our diet now, sleep better, have more energy through the day, hair and nails thicker and healthier, skin has less breakouts. I didn’t realize how ‘sick’ I felt daily until I started eating this way.

        I’m in complete agreement with Kelley regarding her explanation of the diet but I do understand it takes hearing it a few times to wrap our heads around the concept. As a personal side note, my doctor told me (2013) that I was obese, showing signs of insulin resistance, and on my way to metabolic syndrome and Type 2 diabetes. I thought it was just my age or hormones. I thought my diet was relatively healthy and ‘clean’. The only advice she gave me was to exercise more to lose the weight and slow my progression to Type 2.

        I didn’t have an extra 3-4 hours per day to exercise and (without a lot of self-control) I spent most days hungry all the time. I didn’t believe I could make the successful switch to portion control and counting calories. My daughter – who had gained an extra 40-50 pounds during college and as a result of an unhappy relationship – started studying nutrition at that time. Together we learned that our own bodies are better ‘regulators’ than our brains once we learn to feed it correctly.

        This is getting to be a long story – and I apologize for that but I hope it helps others to ‘see’ how we wrapped our head around ‘balancing macros’ instead of ‘counting calories’…

        I had been addicted to empty carbs (sugar, bread, potatoes, rice, etc.) for many years so that was the first part of the journey – realizing that I wasn’t going to starve without the carbs and losing the habit of eating all day long. When you’re filling up on empty carbs you are hungry all day long. With that old habit (eating all day long), and new information (fats and proteins are better than empty carbs for satiating the body), I ate whenever I was even slightly hungry. Not counting calories, not following some eating plan, never feeling deprived or allowing myself to feel hunger. In retrospect I suppose I ate over 3000 calories per day in those first few weeks – and I still lost weight and started feeling better.

        I don’t suggest meal plan specifics for anyone. As Kelley alludes to above, each of us have different metabolisms and requirements. It is a far better path to balance macros, listen to our body’s signals and cravings once we’re well again (for me that was dealing with the carb addiction), eating only when we’re hungry and only enough to satisfy that hunger. A ketogenic diet is quite liberating and empowering in that sense – no dictation from a stranger with a different metabolism on how much, at what time, and how often any one of us eats. Our own bodies will show us the way.

        With our heads around the ‘track macros’ instead of calories/portions, we found a few free mobile apps that helped us to do so easily. Initially it was a bit of extra time but once you get used to eating in the way that makes you feel great and you understand how your body processes different foods, you don’t need to track because you’ve formed new eating habits for yourself.

        I believe this to be the perfect diet for chronic dieters (those of us who jump from one person’s diet plan to another) because we learn about nutrition and our body’s needs through each stage of life.

        So…low in carbs, moderate protein, and high fat…and keep all sources as clean (organic and natural) as possible or as your budget allows. I mostly use my carb macro in the most nutrient-rich leafy or cruciferous greens with a variety of virgin oils. On lean meats I load on creamy sauces or home made mayo, and I enjoy fatty meats (bacon, chops, steaks, ground) from grass fed or pasture-raised animals al fresco. My personal macros for maintenance, health and energy are about 65F:25P:10C. To this day I do not portion my foods or count calories.

        I hope that long stream of rambling helped and didn’t deter you from digging deeper into the concepts of a ketogenic diet. I truly believe that my life changed when I learned to look at my food from a macro perspective and I’ve witnessed hundreds of others saying the same. I am happy to help or answer questions at any point of your journey.

        In closing – because Kelley’s post was originally about cancer and the Ketogenic diet – I do want to add that what I’ve written above does not factor cancer into the equation. There are very specific protocols to follow in those scenarios of which I have no experience. I have spoken to a few experts and read some of the literature on Ketogenic diets for cancer and I would push towards that path for recovery of myself or a family member.

        • Laura thank you so much for your thoughtful answer.
          I agree with all you said about not trying to copy another’s specific eating plan.
          I guess I have missed Kelley’s post on the Ketogenic diet and how to follow it with her recommendations on how to apply to one’s own situation.
          Is there a specific post I might be directed to?
          Thanks again.

          • I think she has plans to write more on the topic, but other than the page we’re on (Keto and Cancer), I see only one other article here on the Ketogenic diet. Maybe it will help?

            I’m so glad you’re excited to learn more (and I didn’t scare you away with my rambling). This diet literally changed my life – I hope it brings joy and health to yours.


  7. my 2yr old son is fighting stage 3 pediatric melanoma, where can I find more kid friendly recipes for favorites like corndogs, man n cheese, grilled cheese sandwich, etc.?

  8. Well, I would like to say, I have cancer of the tongue, don’t hear to much about this much on sights(never heard of, I suppose), well I have been through the internet, on so many sights, and for books on food, even considered raw foods, but I must say, with all that searching and reading, I still don’t know which way to go. Doctors where I live know nothing about it much as going alternatively on medicine. I am stressed with all this knowledge and books on this matter, and as I said, still don’t know what to do that is going to help me in my journey to get better. I know, the longer I leave this and don’t do something, it will get worse for me in the long run. Is there anyone else who can guide me in food ways. Would love some help. Thanks Kelly, you are doing a great job, and I would love to hear more on you diet meals, that are coming up. Maybe in some little way, it may help me to have a menu in front od me to follow. I am not good at doing my own thing.

  9. I’m a graduate student doing cancer research and have done these experiments in mice – I can vouch for the fact that adding a ketogenic diet to standard chemotherapy/radiation improves the efficacy of the therapy. However, this article is incorrect in stating that the researchers in Florida found that “The ketogenic diet was also shown to work better than traditional chemotherapy.” I’ve read the papers you’re referring to and couldn’t find anywhere in those articles where the researchers compared KD alone to standard chemotherapy. I would hate for someone with cancer to read this article and turn down chemotherapy that may save their life in favor of KD alone, which has not been proven in clinical trials to work better than chemotherapy. I would encourage cancer patients to discuss with their doctors adding KD to their current treatment regimen, rather than using it as a replacement.

    • Kelley Herring says:

      I believe every person should make informed decisions with the support of their trusted healthcare provider. That is why I state at the beginning of this article: “a ketogenic diet is certainly not the only thing that should be included in a cancer-fighting protocol”

      With that said, I firmly believe that good medicine doesn’t kill the patient along with the disease. And unfortunately, very often that is what chemo and radiation do.

      One of the articles I reference here, which you said you read, Cancer as a metabolic disease;implications for novel therapeutics (Oxford Journal 3-1-14), states: “Non-toxic metabolic therapy should become the future of cancer treatment if the goal is to manage the disease without harming the patient”

      Dr. Thomas N. Seyfried, lead researcher on this article, and author of the book Cancer as a Metabolic Disease has stated:

      “The reason why the ketogenic diet is not being prescribed to treat cancer is purely economical. Cancer is big business. There are more people making a living off cancer than there are dying of it.”

      He also says:

      “The standard of care has been an abysmal failure for cancer… The ketogenic diet may one day replace the standard of care for most cancers. To those who doubt me, I say: ‘Prove me wrong.'”

      The statistics support this…

      The article “The Ketogenic Diet and Hyperbaric Oxygen Therapy Prolong Survival in Mice with Systemic Metastatic Cancer”, which you also read, states:

      “KD alone significantly decreased blood glucose, slowed tumor growth, and increased mean survival time by 56.7% in mice with systemic metastatic cancer

      Does chemotherapy increase mean survival time by 56.7% in systemic metastatic cancer? According to the SEER Stat Fact Sheets at the NIH, the 5 year survival for metastasized colorectal cancer is 13.1% and metastatic breast cancer is 25.9%, just as two cursory examples.

      Of course, we can’t forget the important concept of “quality of life”, which, in my estimation further bolsters the argument for non-toxic therapies like KD.

      I know the choices I would personally make if I were diagnosed with cancer. And they don’t include chemo or radiation. I encourage every individual to do their own research and explore the many non-toxic options available.


  10. Michael Sackin says:


    The theory behind the ketogenic diet looks good, but

    1. being devil’s advocate I read at

    that under a ketogenic diet: “For one thing, if deprived of glucose, cancer cells can adapt, diversify, and hijack our metabolic system, altering fatty acids and certain amino acids like glutamine for energy production. They can also make glucose through the catabolic breakdown of healthy tissue. When this gets out of control, cancer-related cachexia develops, resulting in weight loss, muscle atrophy, and loss of appetite”

    2. Where are figures on success rates for the method? I draw a near-blank on the web

    3. Can you say why people with cancer should use other methods in addition to a ketogenic diet?

    4. Which other method(s), in particular, for the Waldenström’s globulinaemia, which is what I’ve got. It’s a slow, non-Hodgkin lymphoma. Mine was diagnosed in late 2010. I’m still virtually symptom-free, but blood tests show that it is slowly but surely creeping up on me, and I’ve been terribly slow choosing an alternative method or methods. I have had no orthodox treatment and have no intention either, but I’m quite careful with diet

    5. How does one use trial and error to determine whether one’s diet has become ketogenic? I’d have thought that use of keto stick was sufficient. I gather that I should also use a blood testing kit to check that the blood sugar level is kept down to around 4.0.

    Sorry so many questions.

    Look forward to answers!

      Hi Michael,
      Have you talked with a functional medicine practitioner? That would be the first place I would start, seeking out a cancer specialist using their “Find a Practitioner” search tool, to discuss your options. Every cancer is different, every person is different. An educated professional will guide you through the process based on your own situation.

      There are many ways to establish if you are in ketosis. Martina at Keto Diet App does a great job at discussing those.

      For success with the ketogenic diet and cancer, please check out Chris Gunnars great article and distillation of the research at Authority Nutrition. You can also see clinical trials available with a search online.

      I hope this helps you on your path to healing.

      Be Well,

        Dear Kelley,

        Thanks so much for the incredibly quick and comprehensive reply. The article by Martina on Ketosis and measuring ketosis looks great and authoritative too, as does the article by Kris Gunnars. However, that article is quite sobering. Results on actual humans really don’t look good at all, and he also mentions gluconeogenesis, which is probably partly what my “devil’s advocate” clause was about.

        Finding a functional medicine practitioner might be a good idea. I’m in the UK. I have been thinking that one simple method might be sufficient, but examination of each one in turn yields doubts in my mind. That’s partly why I’ve been so slow in deciding. On the other hand, anything complicated is liable not to get done; hence trying to strike a balance between simplicity and effectiveness.

        Thanks again.

          Hi Michael,
          Happy to help and I do hope you find the right practitioner and create a simple, effective plan that works for you.

          You’re right, gluconeogenesis can definitely be a concern when the ketogenic diet is not properly configured in terms of % of calories from macronutrients. The body is adept at converting protein to carbs for fuel when it needs to. Having too much protein can be problematic in terms of getting into or maintaining ketosis.

          I’d love to hear how your search and healing process goes. Please keep me posted!

            Dear Kelley,

            Many thanks again. From the very clear article by Kris Gunnars it really looks, alas, as though the track record of a ketogenic diet for actually curing cancer is basically non-existent. At best it seems that it can hold back its progression, at worst not even that.

            I hadn’t picked up on the point about the problem of gluconeogenesis being dependent on the % macronutrients, but this looks to me like a secondary issue.

            Other front runners at the moment are DMSO (maybe involving going to Cancún in Mexico, but for $thousands) and cesium chloride, where the main problem is getting proper support, thanks to gagging by the FDA in the USA and inter alia by the 1939 Cancer Act in the UK.

            I’ll keep you in the picture. Thanks for that (very busy week ahead).

  11. Hi!
    In a short 3 months of eating keto, I have cleared my mind fog, my afternoon sluggishness, my IBS, my insomnia, my moodiness and I’ve lost 27lbs. I don’t crave anything!! My recent blood tests were perfect, as is my blood pressure. You can find contradicting information for every single topic…sometimes you just need to try it to find out for yourself. This is a very easy lifestyle to live. And the benefits are outstanding. Thank you for promoting this lifestyle.
