Which diet is best for cancer healing?

One of the most common questions people ask our Ezra Wellness Professionals after receiving a cancer diagnosis is: “What should I eat now?”
For many individuals exploring integrative or alternative approaches to healing, nutrition quickly becomes a central focus, because the body’s internal environment matters greatly during cancer treatment and recovery – including metabolism, inflammation, blood sugar regulation, immune resilience, gut health, and nutrient status.
While conventional medicine often prioritizes surgery, chemotherapy, radiation, and pharmaceuticals, nutritional strategies are often ignored. Yet we believe in the research surrounding the nutritional value of healing: It deserves far more attention than it receives.
The reasoning for this is simple: Every single cell in the body is built from, repaired by, and fuelled through what we consume.
The modern diet problem
One of the major concerns we see is that modern diets place the body under constant stress, long before illness ever develops. Diets high in processed foods, refined sugars, artificial additives, excessive alcohol intake, ultra-processed seed oils, and nutrient-poor convenience foods have become normalized in many households. Over time, these dietary patterns contribute to:
Chronic inflammation
Blood sugar instability
Insulin resistance
Digestive dysfunction
Nutrient deficiencies
Increased oxidative stress
Poor metabolic health
Many people are also following these toxic, nutritional-lacking diets while chronically stressed, sleep deprived, sedentary, and exposed to increasing environmental toxins; all of these factors influence how well the body functions over time.
We often describe this as the body’s “terrain” becoming compromised. What does that mean? The term “terrain” refers to the body’s internal environment – the overall condition in which cells function. The idea is that healing becomes more difficult when the body is overwhelmed by:
Chronic inflammation
Poor nutrition
Blood sugar dysregulation
Digestive burden
Toxic overload
Ongoing stress
Nutrient depletion
Improving the terrain helps open pathways for the body to focus more effectively on repair, regulation, detoxification, and recovery. Of course this does not mean diet alone will cure your illness, but a healthier internal environment better supports the body while undergoing a healing pathway.
But of course it makes sense, wouldn't you agree? You have often felt great gratification from a healthy meal rather than an unhealthy one – and that is your body telling you what it prefers.
Why nutrition matters with cancer
Cancer and its healing pathways place enormous stress on the body; during this time, the body requires adequate nutrients for tissue repair, stable energy production, immune system support, blood sugar regulation, reduced inflammatory burden... the list goes on!
Metabolic health plays an important role in cancer progression and recovery. This is partly based on the “Warburg Effect,” which observes that many cancer cells rely heavily on glucose fermentation for energy. Because of this, dietary approaches that lower blood sugar spikes and reduce excessive glucose availability have gained much attention in metabolic cancer research.
This does not mean sugar alone “causes” cancer, nor does it mean dietary changes are the only cure – but nutrition helps support a healthier internal environment while the body is healing.
Why conventional medicine overlooks nutrition
The truth of the matter is that nutritional education in conventional medical training is very limited, with most doctors studying on average 20-25 hours of nutrition during their first four years of medical school – and we think that is unacceptable. In hospital settings, the primary focus is typically on tumour removal, drug therapies, radiation protocols, and stability during acute care.
Nutrition may be discussed mainly in terms of calorie intake and preventing severe malnutrition (often followed by a suggestion for a protein/fat "shake" off the drugstore shelf), rather than exploring how specific dietary patterns may influence inflammation, insulin signalling, metabolism, mitochondrial function, or immune activity.
As a Wellness company, we strongly believe that chronic inflammation matters, blood sugar balance matters, gut health matters, metabolic health matters... and all of this is very influenced by the food quality of our clients' intake.
Why a Keto diet is often recommended
A ketogenic diet is a very low-carbohydrate, moderate-protein, high-fat dietary approach that shifts the body into a metabolic state called ketosis. When the body is under ketosis, instead of relying primarily on glucose for energy, it begins producing ketones from fat. This state helps to:
Stabilize blood sugar levels
Reduce insulin spikes
Lower inflammatory burden
Improve metabolic flexibility
Support steady energy levels
Reduce dependence on refined carbohydrates
Healthy cells are able to adapt to using ketones for fuel, making cancer cells less metabolically flexible. In addition, people on a Keto diet report reduced brain fog, more stable energy, fewer cravings, improved focus, and better appetite regulation... these are all positive signs the body is already healing!
Why a Carnivore diet is often recommended
A carnivore diet focuses primarily on animal-based foods such as meat, fish, eggs, animals fats, and sometimes dairy – depending on tolerance (but this dairy must be very clean, organic, unpasteurized).
While it may seem controversial, a Carnivore diet help to eliminate many inflammatory triggers found in processed foods, seed oils, refined sugars, additives, and certain plant compounds that some individuals struggle to tolerate.
Those clients we have recommended a Carnivore diet report benefits such as, reduced digestive irritation, stable blood sugar, reduced bloating, improved satiety, reduced cravings, and an increased protein intake for optimal tissue repair.
Animal-based foods are also highly bioavailable sources of amino acids, iron, zinc, B vitamins, creatine, essential fats – al which are important for immune function, tissue maintenance, recovery, and preserving muscle mass during healing.
Sometimes Ezra Healing clients will begin their healing journey on a Carnivore diet, and transition to a Keto diet as their healing numbers improve.
Diet is never a one-size-fits-all
It is important to understand that no single diet works for every individual or every cancer type. What supports one person may not support another. Factors we consider when making recommendations include, current health status, digestive function, nutrient deficiencies, muscle mass, metabolic health, and other factors. The goal is neither perfection nor restriction.
Whether through ketogenic nutrition, carnivore-style eating, or another personalized healing protocol, the growing message is that what we consistently put into the body matters.
