Cancer can happen through multiple disorders due to different factors, such as environmental factors, habits, lifestyle, food, etc. Environmental facts cause 80–90% of all cancers; 30–40% of cancers are directly related to our diet. For decades, researchers have been trying to invent an appropriate therapeutic diet to control cancer, yet there is no clear evidence as to which diet would support carcinogens and which type of diet does not.
There were many dietary recommendations proposed to reduce the risk of cancer. The primary dietary factors that increase cancer risk are obesity, and alcohol consumption associated with lower amounts of fruits and vegetables. Studies have proved that the consumption of processed meat would increase the risk of breast cancer, colon cancer, and pancreatic cancer.
Cancer cells are fed and love sugar or glucose. Thus, if one stops eating carbohydrates which they are converted to glucose in the body, cancer cells may eventually be destroyed. Cutting carbohydrates out of your diet could be a very effective way to combat cancerous cells. Cancer cells can survive only on glucose. However, other normal body cells can live on either glucose OR ketone. In other words, normal cells have the flexibility to live on either glucose or ketone. But cancer cells do not have that flexibility and use only glucose to survive.
A ketogenic diet has almost zero carbohydrates, which are mainly natural proteins and fat. In general, there is no sugar, no salt, no junk, or fast food, no processed food, such as hot dogs and cold cuts (because carbohydrates are added to them) in ketogenic diet.
Natural fats, such as avocado, coconut, olive oil, nuts, and even some butters are good and healthy to be included in a diet. In a ketogenic diet, one needs to avoid trans fats, such as margarine which is man-made or processed, carbohydrates, such as candies, cakes, whipped cream, ice cream, breads, pastas, flours, and donuts. Eating too many carbohydrates can also cause inflammation in the body.
The typical American diet usually includes 60% carbohydrates. It is recommended to moderate your diet by eating 25% carbohydrates to prevent cancer, and be on strict ketogenic diet to combat cancer cells. Always consult your doctor or nutritionist for advice about a regular diet!
Our body cells including cancer cells are energized by glucose. In case you're starving, then the cancer cells become deprived and switch to the alternate fuel called ketone bodies. What really happens here is that your normal body cells have the ability to adapt from using glucose to using ketone bodies, where as cancer cells lack this metabolic flexibility. Introducing a Ketogenic diet exploits this lack of flexibility and kills the cancer cells.
There is no strong evidence that supports the claim that a Ketogenic diet prevents and controls cancer. However, some animal studies on guinea pigs and mice demonstrated positive results in preventing the growth of cancerous cells. The Ketogenic mechanism works on a high-fat and low calorie diet. The healthy cells can convert fatty acids to glucose for energy to be used for normal cells. But cancerous cells cannot respire without a significant source of glucose from carbohydrates and a Ketogenic diet leads to growth retardation of cancer cells.
A comparative study that was done on mice has proved a beneficial effect of Ketogenic factors where a group of mice were injected with tumor cells, and then fed different diets. After 60 days, the results showed those who ate a Ketogenic diet had tumors that were 33% smaller than those who ate a traditional diet of equal fat and carbohydrate content. This is an indication that a Ketogenic diet has anti-cancer properties, though it contains fat ingredients.
