It is not only foundational but fundamental and essential to feed a cancer patient a high protein, low carbohydrate diet. There are numerous studies to support this as well as exceptional clinical outcome data.
It has been powerfully said by many top holistic veterinarians, that any integrative therapy for cancer will have a reduced effect if the patient does not follow a cancer diet. This is a simple yet not easy concept to implement. Parallel to the human side of nutrition, there is an explosion of information that contradicts previously held beliefs about diet and nutrition. Coupled with the lifestyle of today that demands convenience, many people armed with knowledge still require coaching to work through lifestyle changes.
In 1931 a German physician/scientist, Otto Warburg MD, PhD, received a Nobel prize for proving that all cancer cells use anaerobic metabolism (burn sugar without using oxygen) to produce energy. The problem (for the cancer cell) is that this mechanism is 18 times less efficient than the aerobic (oxygen utilizing) metabolism that our normal cells use. That means the cancer cells need 18 times more sugar than normal cells to grow and prosper.
Animals' ancestral diet is a ketogenic diet. Specifically this means that a high quality, human grade, bioavailable protein should comprise 60-80% of the diet for dogs and 90% for cats. Healthy Fats: 10-15% for dogs, 10% for cats. (The type of fat and amount is very individualized to the animal). And vegetables: 10-30%.
Because this can be a big change for the animal that has been on a kibble diet, possibly complicated by food sensitivities and a poor microbiome, a cancer diet plan and implementation for an individual patient is created and discussed in the consultation(s). There is not a one fits all design.
