Therefore, he set out to explain a ketogenic diet and cancer in less than 1,0. A Ketogenic Diet for Cancer: In Fewer than 1,0. Words A ketogenic diet is one in which carbohydrates, and to a lesser extent, protein are restricted in the diet and replaced with fat. This treatment has been effective for seizure control in epileptic children for over a century.
It may also provide a benefit in cancer subtypes with outcomes closely related to obesity and metabolic risk factors, such as breast cancer. It generally implements a ratio of 4: 1 fat to protein and carbohydrates. However, many people will reach significant ketosis when their carbohydrates are limited to less than 5. What Are Ketones? Ketones are energy sources produced by our liver that can freely cross our blood brain barrier to provide a source of energy for our neurons (brain cells). These ketones replace glucose when it is not available, such as during fasting, during the winter months in traditional societies, and all the time in modern hunter- gatherer societies like the Inuit Eskimos or Maasai tribesmen, who consume very little carbohydrate sources. Frankly, many readers of this blog likely have a significant amount of ketones floating around in their blood some mornings, and the low- carb followers even more often. How Can a Ketogenic Diet Help Cancer Treatment? Much like most things in cancer, including chemotherapy, biologic agents, and even radiation therapy, we do not quite know exactly how a ketogenic diet works. However, there are several potential mechanisms: First and foremost a ketogenic diet may work simply through decreasing available glucose to tumor cells. Many decades ago, Otto Warburg stated that a hallmark of cancer was the uptake of glucose by cancer cells. Have you heard of or are you considering the 500 calorie diet? Here's a breakdown of what it is, how it works, and what I learned during the first 20 days. Are detox symptoms on a Paleo diet normal? Our nutritionist explains how to handle the transition from the dreaded detox into thriving on Paleo. How to do an elemental diet for treating SIBO or GI disorders; elemental formulas, recipes, symptoms, and surviving without food. Cancer cells rely on glucose for energy; therefore any method of limiting this may help to “starve” cancer cells. A devastating disease. Retrospective data has shown that in patients with GBMs, the higher their blood glucose, the worse they do with treatment. Other data has shown that this occurs due to deficient and defective mitochondria. Interestingly, our cells use this process as well, especially when oxygen is not available. This is what occurs in muscle cells during sprinting or lifting heavy weights. Lactic acid is released, resulting in a burning sensation within the muscles. Cancer cells, on the other hand, appear to use glycolysis for energy regardless of whether oxygen is present or not. This process is very inefficient for energy production, and mitochondria can create around 2. ATP than the process of glycolysis. A ketogenic diet allows the body to rely on the mitochondria for energy. Lastly, mitochondria are the organelles within our cells that can recycle old parts or kill cells that appear to be malfunctioning, or in other words mitochondria are used to kill cells in our body that may turn malignant. Upregulating the mitochondria may serve as a way to increase our body’s housekeeping processes that can eliminate potential cancerous cells. Also, while our normal cells can use ketones for energy, data shows that cancer cells are unable to effectively derive energy from ketones. Due to their faulty mitochondria, cancer cells also rely on glucose to fix free radical damage. Much like our normal cells, cancer cells are constantly experiencing bombardment with free radicals, and maybe even more so than our cells. Since their mitochondria do not function properly, they rely on even more uptake of glucose, which is used to counter free radical damage. Cancer cells have receptors on them, like the insulin growth factor receptor (IGF- 1. R). Insulin then activates several pathways that increase cancer growth and survival. A recent study in advanced cancer patients confirmed the ability of a ketogenic diet to significantly decrease the insulin pathway in tumor cells. Another pathway that has received much attention is the AMP- K pathway. When upregulated, it inhibits several pathways that are activated by insulin. Studies in humans have shown that the diabetes drug Metformin can activate AMP- K, as can intense exercise and carbohydrate restriction. In fact, there are now trials supplying breast cancer patients with metformin as part of their treatment. Therefore, minimizing the pathways that lead to cancer growth and activating those that limit it is another potential mechanism by which a ketogenic diet works. Abbreviations: IF = intermittent fasting, IRS = insulin receptor substrate, IGF- 1 = insulin- like growth factor 1, IGF1- R = insulin like growth factor 1 receptor, PI3. K = phosphatidylinositol 3- kinase, m. TOR = mammalian target of rapamycin, LKB1 = liver kinase B1, AMPK = AMP- activated protein kinase. Molecular Pathways Affected by Intermittent Fasting. The IF icon indicates pathways affected by IF. IGF- 1. R, AKT, IRS, m. TOR and PI3. K are decreased with IF. There are the same pathways that can be induced by intermittent fasting, to turn on autophagy. Activation of the insulin receptor and several pathways downstream within cancer cells allows them to more readily fix damage from chemotherapy and radiation. However, keep in mind that radiation therapy works mostly by interacting with the water molecules in and around cancer cells to create free radicals that attack the cancer cells, causing DNA damage. Restricting glucose through a ketogenic diet may take advantage of this inability to counter damage from free radicals, making radiation more effective. A study in mice has shown that radiation therapy efficacy is significantly increased in the face of a ketogenic diet when treating brain tumors. Last but not least, some people have hypothesized that ketones themselves may fight cancer. This is more speculative with little data, but reports on many societies, most notably those in Africa. Inuit Eskimos reveal few cases of cancer. Urquhart served as the district surgeon of the far north, and in seven years with all the x- rays and surgical equipment of his day, has published that he never say a single case of cancer, and this was in people of all ages. In the next decade, the power of diet, exercise, and specifically ketogenic diets in the prevention and treatment of cancer may take a front seat within the field of oncology. A ketogenic diet is just one of many nutritional and lifestyle interventions that may prove valuable in the fight against cancer. I went over by about 4. References: 1.
