Recently with the popularity of an online video about ketogenic diet for cancer treatment (original link http://www, miaopai, com/show/kI5eOiEkpknIhnG7OMrW8A__, htm), tumors, a huge group of people with the disease, suddenly had the hope of rebirth, so some families through The common misconceptions are as follows: 1. Ketogenic diet is a recipe, bring it to be weighed and cooked, and the tumor will disappear after eating it? Ketogenic diet therapy is indeed a recipe, but it requires doctors and dietitians to develop a diet plan according to the patient’s condition after evaluation, and requires close cooperation from family members, weighing and cooking, and strictly eating ketogenic meals, so that tumor cells may have a chance to disappear. Downloading a random recipe from the internet that you give to your family without assessing the patient’s underlying disease and without a precise calculation of caloric and dietary ratios is risking how much of your life you are implementing an uncertain treatment. The recipes online are currently mainly for children with epilepsy, and the dietary ratio and calories are not appropriate for oncology patients, so you must be careful when choosing. 2. What kind of people are suitable for ketogenic diet for tumor treatment? The ketogenic diet therapy is mainly limited to children with refractory epilepsy in China, and for adults with refractory epilepsy, we have the most patients treated at the Epilepsy Center of Shanghai Deji Hospital, and the age range is limited to young adults in their twenties and thirties. However, the tumor patients who have recently consulted me, including those who have been treated in our hospital, are generally older, mostly over 60 years old, with the oldest being 72 years old. Due to the age difference, most patients have other diseases in combination with the tumor itself, such as diabetes, hypertension, hypertriglyceridemia, hypercholesterolemia, and patients over 40 years old often have a combination of bilateral carotid arteries and lower limb arteries. Patients over 40 years old often have bilateral carotid arteries and lower limb arteries accompanied by stable or unstable plaques of different sizes, especially liver tumors, abnormal liver function, often accompanied by ascites, and some patients are cholecystectomized. Combined with the decreased appetite, gastrointestinal intolerance, physical exertion, decreased resistance and other discomforts caused by the tumor itself, this adverse reaction is often exacerbated when doing this high-fat ketogenic diet. The high-fat diet and ketosis state are likely to have aggravating effects on the concomitant diseases of some of the tumor patients I listed above, so this diet must be implemented in the hospital after evaluation by a professional physician. 3. Can I try to do the ketogenic diet for tumor treatment directly at home? A year ago, a 72-year-old gentleman with liver cancer was seen by a number of large hospitals and was recommended to undergo surgery after chemotherapy. His own brother had liver cancer and passed away in less than a year after undergoing surgery according to conventional chemotherapy. He secretly implemented the ketogenic diet at home without any examination and evaluation and without letting his children know about it. He told me that he set himself a recipe of nearly 2,000 calories at first and found that his blood sugar did not go below 3,0 mmol/L for a bit, feeling that he was eating too much and slowly lowering it, coming to me for a consultation with more than 1,300 calories a day and losing nearly 20 pounds. The daily ingredients: by 1/3 of fatty meat, 1/3 of olive oil and 1/3 of coconut oil to fill, the rest is other meat, without any intake of vegetables, only supplemented with vitamin B and vitamin C, their own home execution half a month when the cramps coma. This old man had multiple metastases in addition to liver cancer, poor heart function, multiple plaques in bilateral carotid arteries and lower limb arteries, low potassium, low sodium and low calcium. After the evaluation, we reformulated the calories, reduced the proportion of his original diet, added vitamins and minerals, supplemented potassium appropriately, and developed a special recipe that suited his eating habits. After a week of adaptation, he was discharged from the hospital without any discomfort and continued his ketogenic diet treatment at home, coming to the outpatient clinic for regular review. After one month of ketogenic diet treatment, the tumor index decreased significantly. 4. Ketogenic diet therapy has such an amazing effect, why do many doctors not know about it? Many hospitals do not have this treatment method. Ketogenic diet therapy is mainly applied to patients with drug-refractory epilepsy, which has a history of nearly 100 years, and a large amount of clinical data proves that it is a safe and effective treatment method. It has been prevalent in the Johns Hopkins Hospital in the United States and is being promoted worldwide. In 2004, it was introduced to China by Professor Jianxiang Liao, the first ketogenic person in China. Since it is a high-fat diet, it needs to be strictly limited and needs the guidance of experienced doctors and dietitians, which is extremely lacking in the current medical environment in China. Most of these children have misconceptions about the ketogenic diet, or they are worried about the effectiveness of the diet. As the efficacy of the ketogenic diet becomes more popular in China, doctors in many hospitals are becoming more aware of this diet therapy. Is ketogenic diet therapy suitable for all tumor patients? From the perspective of tumor metabolic characteristics, ketogenic diet therapy is suitable for all tumor patients, but there are contraindications to the use of ketogenic diet therapy, mainly from the following points: porphyria, pyruvate carboxylase deficiency, fatty acid mitochondrial transport disorders, β-oxidation deficiency and certain specific mitochondrial diseases, and ketone body synthesis or utilization disorders; if there are metabolic problems in these areas, it is absolutely not possible to use ketogenic diet therapy. If these metabolic problems are present, the ketogenic diet should not be used. In addition to this, there are a number of factors that need to be considered in the patient. Since the production of ketone bodies is mainly related to one’s own metabolism, the level of ketone bodies directly determines the efficacy of treatment. In addition, the sensitivity of different types of tumors to ketogenic diet is different, generally malignant tumors of the brain are relatively sensitive. In addition, whether the efficacy of ketogenic diet can stop the rate of progression of highly malignant tumors is also to be considered. 6. Very good news – ketogenic diet for tumor treatment has gradually been recognized by domestic experts. An adult patient who visited the clinic in February 2016 was introduced by a famous oncologist in Beijing to try ketogenic diet therapy. This patient with heart tumor, who did not have any effective anti-tumor drugs to choose from, was told that ketogenic diet therapy for tumor is currently very hot abroad and has proven to be very effective for malignant tumors, only that even many domestic experts do not understand this effective treatment method and suggested He came to Shanghai or Shenzhen to try ketogenic diet treatment. After a series of tests, he was discharged from the hospital in about 7-10 days and continued to adhere to the ketogenic diet. At present, the patient’s overall condition is good, and we are looking forward to the good news of the post-treatment review. 7. Is it possible to treat cancer with ketogenic diet therapy only? There are many different opinions about ketogenic diet for tumor treatment, but theoretically it is effective. There are also successful cases in foreign countries. However, there are no successful cases in China, only some patients voluntarily accept the experimental trial of ketogenic diet therapy. At present, many oncologists have a negative attitude towards this. Therefore, I suggest to our family members that the patient’s cancer, which is a worldwide problem, the more recognized practice is radiotherapy and surgery as well as targeted drugs. If there is hope for surgery or radiotherapy, I suggest that you should try it. The ketogenic diet is only a last resort and can only be used as a complementary treatment. Often, some family members or patients themselves have misunderstandings about starving cancer cells, not eating staple foods, and seriously under-intaking protein and fat, resulting in the deterioration of the patient’s health, severe malnutrition, low immunity, and no ammunition to fight cancer, so how can the cancer roll away? A true ketogenic diet must be obtained under strict evaluation and calculation. Simply reducing the intake of staple foods in daily life, resulting in insufficient nutrient supplementation and insufficient calorie intake, will not only be of no benefit in fighting tumors, but will also have a great impact on oneself. For the ketogenic diet currently tried for oncology patients, we have made improvements that are less demanding than the traditional ketogenic diet for epilepsy patients, with a dietary ratio of about 2:1 and a relatively high caloric intake, trying to keep the patient with sufficient energy supply, appropriate nutrient supplementation, increased protein intake, stabilization of the patient’s weight, and close attention to the uncomfortable reactions caused by high-fat diet.
