  Hi I was diagnosed with &nbsp;AML that is leukemia in june 2015. As it was metastasized, doctors sent me home with 6 weeks to live. I researched and changed my diet and lifestyle radically. I am in remission for 9 years.

  I’m an Endoscopy RN and got my hand slapped by management for giving a newly diagnosed cancer patient links to Seyfried’s work. &nbsp;I urged the patient &nbsp;to do their own research.<br>Management accused me <br>of practicing medicine and threatened to fire me if I do it again.<br>The health care system is so broken😡

  I am a South African diagnosed with stage 4 breast cancer. Having listened to this interview has helped me understand so much more about managing diseases by mainly changing the lifestyle( diet) but also not to fear cancer. Mental wellness is the departure point and daily managing glucose and glucotine in our bodies. I find , with that, similarities with a diabetes patient. Thank you so much, ready to face and fight cancer from another angle

  Loved this discussion. I am a Stage 4 brain tumor GBM survivor. I was given 6 months to live over 5 years ago. Didn’t know about dr Seyfried but I followed the same keto diet after doing research. Added meditation and physical exercises to my life. Also reduced stress in life. Now I am healthy and pursuing my spiritual interests. REFUSED DRUGS and chemo after first phase that made<br>Me miserable. Love to help others from my experience.

  I started a carnivore diet 8 months before I was diagnosed with renal cell kidney cancer and a year before I was diagnosed with a Bellini Tumour and given 10 months to live. I had surgery but no chemo or radiation were offered since this cancer kills everyone. That was 4 years ago. Carnivore diet starved this cancer so it grew very slowly and the surgery was successful.

  When I had cancer 2 years ago j had no idea about metabolic therapy so i had standard of care .cancer free because im lucky and had a curable type..now i work on my mitochondria with fasting.. excercise... alpha lipoic acid... coq10..red light therapy...ppq.. meditation...keto diet..no sugar...last week my ketones were 2.7 and glucose 59...after a 2 day fast and keto diet.....this changes every week....i take berberine before meals..

  Have have just lost a loved 1 to aggressive chemo. 2 days after completion his muscle totally went. Oncology gave no directive to him before he started &nbsp;SOC. No recommended supplements. Then ended up palliative and given glucose drinks &nbsp; Just passed on the 24th of Feb after 23 days in palliative care. Hospital collected huge $ for his stay. This is a hospital in Saskatchewan Canada. I am angry that these standards are happening. 😡

  ALWAYS wonderful to hear Prof Seyfried talk. Not only can fasting and a low carb diet help a great deal with preventing and healing cancer but also with undoing the collateral damage of chemotherapy, which is often life wrecking or even life ending. It can also do much more! &nbsp;Some benefits of occasional extended fasting and lowering carbs in the diet: High blood pressure is lowered to normal levels very quickly while fasting. Fibrosis/scarring is reversed over time, including in the heart and lungs.<br><br>Vitamin D plasma levels are increased as fasting improves metabolic health, and vitamin D in turn increases autophagy. When insulin is high, vit D stays locked in the blood cells.<br><br>Fasting stimulates phagocytosis, the ingestion plaques, growths and pathogens by the immune system. This will also remove spikes quicker, whether natural or unnatural in origin!<br><br>Your body recycles up to 1/3 of all immune bodies in a 72h fast, rejuvenating your entire immune system. This helps prevent the onset of new autoimmune conditions, which develop through a leaky gut and damaged immune system.<br><br>Blood sugar and insulin are lowered when fasting, reducing inflammation and allowing the immune bodies to move freely through the body.<br><br>Fasts from 36-96 h increase metabolic rate due to norepinephrine release<br><br>Fasting restores your circadian rhythm to normal over time.<br><br>T cells and T reg cells are vital in fighting cancer, autoimmune disease and infections but as we age the thymus stops making as many of them. Fasting releases stem cells, which then can become new T cells. It also releases growth hormone, which regenerates the thymus itself!<br><br>Fasting restores NAD+ and increases nitric oxide release to open blood vessels.<br><br>Reflexes and short term memory are increased. <br><br>Fasting increases anti-aging Yamanaka factors and increases average telomere length in stem cell pools.<br><br>Fasting can help with MS, Depression, BPD, Autism and seizures.<br><br>When you move out of MTOR your body shuts down the building blocks of the cell required for viruses to replicate.<br><br>The hunger hormone ghrelin also lowers with extended fasting and rises from dieting. <br><br>What breaks a fast? Anything with protein or carbohydrates in it will break a fast but most teas and herbs are OK. Supplements and meds often break ketosis directly or contain a filler that will. Many meds are dangerous to take while fasting.<br><br>Does fasting lower testosterone? No, it raises it when the fast is broken by increasing lutenizing hormone. Fasting also increases insulin sensitivity, which helps with muscle building.<br><br>Fasting activates autophagy (literally self eating). This will cause cells to recycle damaged proteins and foreign matter such as viruses.<br><br>Lowering insulin via fasting virtually eliminates chronic inflammation in the body. <br><br>Weight loss from daily caloric restriction has 1/4 to 1/3 of the weight lost as lean tissue while many studies show fat loss from 36 h fasts without losing any lean tissue! <br><br>The obese will lose loose skin while fasting, but the frail will have increased growth hormone release, which helps to make more lean tissue and reduce frailness.<br><br>Fasts of 36-96 will not affect short term female fertility or affect menstrual cycle. They also may increase long term fertility for some women.<br><br>Just 24h of fasting can cut your leptin levels in half! This reduces leptin resistance, which impairs immune function. <br><br>Stomach acid is reduced over time while fasting and can allow for the healing of treatment resistant ulcers. Some patients may need continued acid reduction medication while fasting.<br><br>Your brain also prefers to burn ketones at a rate of around 2.5 to 1 when they are available in equal quantity to glucose. Except for brief periods of very intense exercise, your body mainly burns fats in the form of free fatty acids. <br><br>It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency. Increased mitochondrial function also has the added benefit of increasing your metabolism, fighting infection and cancer prevention!<br><br>Fasting releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth. This can help a great deal with diseases like MS, peripheral neuropathy and Alzheimers.<br><br>When not in ketosis, the brain can only burn carbohydrate, which produces a great deal of damaging ROS the brain has to deal with.<br><br>Fasting also increases telomere length, negating some of the effects of aging at a cellular level.<br><br>When you fast, this stimulates apoptosis in senescent or genetically damaged cells, destroying them. Senescent cells are responsible for many of the effects of aging and are a root cause of the development of cancer. <br><br>A fasting mimicking diet for 3-5 days in a row also provides many of the same benefits as water fasting. FMD usually has 200-800 calories, under 18 g of protein and extremely low carbs.<br><br>Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia. They also help with dementia and many other issues even if you take them while not fasting!<br><br>Glycine and trimethylglycine can also be useful supplements while fasting that won&apos;t break ketosis and have many benefits.<br><br>Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or certain forms of hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution as it could lead to ketoacidosis. If you experience extreme symptoms of some kind, especially dizziness or tremors, then simply break the fast and seek advice.<br><br>Resources:<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6141719/<br>https://pubmed.ncbi.nlm.nih.gov/20921964/<br>https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2265.2005.02288.x<br>https://academic.oup.com/ajcn/article/81/1/69/4607679<br>https://www.amjmedsci.org/article/S0002-9629%2815%2900027-0/fulltext<br>https://www.collective-evolution.com/2017/05/16/study-shows-how-fasting-for-3-days-can-regenerate-your-entire-immune-system/<br>https://pubmed.ncbi.nlm.nih.gov/7714088/<br>https://www.nejm.org/doi/full/10.1056/NEJMoa012908<br>https://pubmed.ncbi.nlm.nih.gov/6859089/<br>https://www.sciencedirect.com/science/article/pii/S1931312809002832<br>https://pubmed.ncbi.nlm.nih.gov/15522942/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7607739/<br>https://pubmed.ncbi.nlm.nih.gov/25909219/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5783752/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1413655/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5783752/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8470960/<br>https://europepmc.org/article/MED/22402737?javascript_support=no<br>https://pubmed.ncbi.nlm.nih.gov/2518860/<br>https://www.ncbi.nlm.nih.gov/pubmed/24905167<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6526871/<br>https://pubmed.ncbi.nlm.nih.gov/23707514/<br>https://pubmed.ncbi.nlm.nih.gov/23408502/<br>https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fasebj.2019.33.1_supplement.819.10<br>https://www.biorxiv.org/node/93305.full<br>https://www.health.harvard.edu/heart-health/abundance-of-fructose-not-good-for-the-liver-heart<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7093158/<br>https://www.ncbi.nlm.nih.gov/pubmed/10859646<br>https://www.ncbi.nlm.nih.gov/pubmed/10232622<br>https://clinical.diabetesjournals.org/content/36/3/217<br>https://www.ncbi.nlm.nih.gov/pubmed/23876457<br>https://pubmed.ncbi.nlm.nih.gov/29727683/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5895342/<br>https://pubmed.ncbi.nlm.nih.gov/33530881/<br>https://www.arcjournals.org/pdfs/ijrsb/v3-i11/7.pdf<br>https://pubmed.ncbi.nlm.nih.gov/27569118/<br>http://www.cell.com/cell-metabolism/abstract/S1550-4131(15)00224-7<br>https://repository.upenn.edu/cgi/viewcontent.cgi?article=1537&amp;context=edissertations<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1779438/<br>https://www.nejm.org/doi/full/10.1056/NEJMc2001176<br>https://pubmed.ncbi.nlm.nih.gov/31877297/<br>https://www.ncbi.nlm.nih.gov/gene/25712<br><br>https://www.cell.com/cell/fulltext/S0092-8674(19)30849-9<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3017674/<br>http://www.sciencedirect.com/science/article/pii/S0005272806000223<br>https://www.clinicaltrials.gov/ct2/show/NCT04375657<br>https://pubmed.ncbi.nlm.nih.gov/20102774/<br>https://n.neurology.org/content/88/16_Supplement/P3.090<br>https://pubmed.ncbi.nlm.nih.gov/31890243/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6407435/<br>https://www.cell.com/molecular-cell/fulltext/S1097-2765(18)30605-1?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS1097276518306051%3Fshowall%3Dtrue<br>https://pubmed.ncbi.nlm.nih.gov/28235195/<br>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2815756/<br>https://www.nia.nih.gov/news/research-intermittent-fasting-shows-health-benefits<br>https://medicalxpress.com/news/2022-10-treatment-pulmonary-fibrosis-focus-telomeres.html<br>https://www.ncbi.nlm.nih.gov/pubmed/25686106<br>https://pubmed.ncbi.nlm.nih.gov/21410865/<br><br>This list compiled over years of research by the user known as Pottenger&apos;s Human on youtube.

  You know what greatly disturbs me that the insurance companies require that you go through the standard of care first which is downright poisonous<br>They make you do that before they&apos;ll help you with any money to cover the alternative protocols which is Ludacris
