The word “fasting” can trigger panic. We all love food, and giving it up isn’t a pleasant thought. However, receiving a cancer diagnosis might change your mind when it comes to fasting. Intermittent fasting is a hot topic these days. Water fasting isn’t as popular because, obviously it’s too hard, and isn’t sustainable. Does fasting kill cancer cells?
No one can dispute the benefits of fasting, such as better digestion and detoxification, increased mental clarity, and weight loss. Not many people associate these benefits in regard to cancer and fortification of the immune system.
Does Fasting Kill Cancer Cells?
Never before in history has our environment been so toxic, with over 85,000 toxic chemicals being spewed into the environment. Our food and water supply, with the onslaught of plastics, GMOs, heavy metals, EMFs, and pesticides, is highly detrimental to health. Medications factor into this as well. From the time we wake up to the time we go to bed, we are bombarded with a sea of toxins.
Why talk about toxins when it comes to cancer? Because they are intricately connected, not just to cancer, but to chronic disease as well. These toxins are damaging to our health, putting us at increased risk for autoimmunity, diabetes, heart disease and stroke. We breathe in toxins, we eat and drink them, and we slather them on our skin.
Toxicity is causing us to be inflamed, exhausted, and to age at a faster rate than we otherwise would. Fasting promotes the removal of carcinogenic toxins and substances from the body. Cancer cells, which are accustomed to metabolizing toxic waste from normal metabolic processes, can’t survive without fuel, and eventually they die. In a fasted state, normal cells slow down and go into survival mode, while cancer cells are deprived and become stressed, leading to their demise.
Formation Of Free Radicals
Free radicals are highly reactive molecules produced by normal processes of metabolism. These reactive molecules are also the result of toxicity. Free radicals damage cells, and bind to cytokines, reducing immune function by damaging immune system pathways.
This decrease in immunity is a set-up for cancer. Fasting is a viable cancer treatment due to the fact that normal cells behave differently than cancer cells while in a fasted state,. Fortunately, we can use this to our advantage.
Inflammation And Cancer
Fasting reduces inflammation. This reduction, not only aids in the prevention and treatment of cancer, but also prevents other chronic diseases that are on the rise. Inflammation is problematic because it is a precursor to a myriad of dysfunctions in the body. There is a direct correlation between inflammation and the development of cancer.
Chemicals, as discussed above, promote inflammatory processes. Couple this with inflammation, and cancer risk climbs. This connection is clearly seen in certain types of cancers, including esophageal, liver, colon, and pancreatic cancer, the latter being one of the most deadly cancers. For this reason, inflammatory diseases, such as colitis, hepatitis, and pancreatitis, are associated with greater cancer risk.
In chronic inflammatory states, immune cells produce reactive molecules, damaging DNA and stimulating cell division, a distinguishing feature of cancer. Inflammation is like a low-grade fire burning continually in your body. This perfect storm of inflammation, DNA damage, and cell division can initiate the development of cancer.
When cells divide and their DNA has been damaged, mutations are more likely to occur. In modern society, many people are living with chronic inflammation that has been going on for years, and even decades. It’s not surprising that cancer rates have increased.

Listen to Dr. Jason Fung’s: “The Complete Guide to Fasting.” He talks about intermittent fasting, same day fasting, and extended fasting.
Intermittent Fasting Guide
Intermittent fasting is a pattern of eating that reduces the window of food consumption. There are a variety of ways to implement intermittent fasting. I personally like the 16/8 method, where you confine your eating to an eight-hour window, fasting for 16 hours. Remember, half of that time includes the time you are sleeping so it’s not as hard as it sounds.
For me, intermittent fasting is the best of both worlds. I get the benefits of fasting, but can still enjoy two meals a day, which is of course much more sustainable than regular fasting. Once you get used to it, intermittent fasting isn’t difficult. Essentially, all you’re doing is not eating after dinner, and skipping breakfast in the morning.
As insulin levels decline, fasting gets easier. High insulin levels cause inflammation, leading to blood-sugar and hormonal imbalances. Elevated insulin can also produce cravings, making it harder to fast. It can take a few weeks to get your insulin levels down, depending on your degree of insulin resistance.
It’s essential to soldier through this time, remembering that it will most definitely get easier. Intermittent fasting is highly effective at improving your fat to muscle ratio, leading to a better body composition, balanced blood sugar, increased insulin sensitivity, and reduced inflammation. This puts your body in a state of health that cancer can’t thrive in.
Insulin Resistance And Cancer
When cells becomes insulin resistant, due to chronically elevated blood sugar, glucose can’t enter the cell, leading to high glucose levels in the bloodstream. This is significant, considering glucose fuels the growth of cancer, and depresses the immune system. When blood-sugar levels are chronically high, a vicious cycle ensues, with the pancreas producing more and more insulin to lower blood sugar.
This is a dangerous situation because there is now more sugar in the bloodstream, which stimulates cancer and tumor growth. It gets worse. Cancer cells metabolize energy differently than normal cells do. Malignant cells have been shown to have increased glycolysis, allowing them to use glucose as a fuel source. Glycolysis occurs in the cytoplasm of cancer cells, as opposed to the mitochondria in normal cells. This is why cancer is often viewed as a disease of the mitochondria.
Glycolysis And Lactic Acid
During glycolysis, cancer cells produce lactic acid, shifting the blood to a lower pH, which can cause cell multiplication. This acidic environment enables cancer cells to survive and thrive. Acidity also causes the cells to store more toxins, and toxins by nature, are acidic. Adding insult to injury, cells can’t dump toxins in an acidic environment, leading to further toxin build-up and acidity.
Oxygen levels are also reduced, providing the perfect environment for cancer to grow. When cells proliferate, they produce even more acid, leading to a cycle of cancer growth, acidity, and more growth. Cancer cells have up to ten times more insulin receptors than do normal cells. This makes them more receptive to insulin signaling, which can promote cancer growth.
Recently, studies have found that cancer cells may even produce and secrete their own insulin. The fact that cancer cells contain more insulin receptors is one reason Insulin Potentiation Therapy, a form of low-dose chemotherapy, is so effective, making it possible to differentiate cancer cells from normal ones.
Intermittent Fasting And Detoxification
Intermittent fasting is a great way to detoxify the body. When you eat, your body is in a building mode, which is not conducive to detoxification. Fasting, however, promotes detoxification and cleansing. By extending this detoxification period, more toxins are able to be eliminated. Many people operate on a 14/10, or 12/12/ hour eating window, leaving little time for detoxification, causing a cascade of negative repercussions.
On the other hand, reducing your eating window, increasing the hours you fast, promotes healing, boosts immune function, and mitigates cancer risk. It’s critical to stay sufficiently hydrated when you’re fasting so toxins can be moved and excreted. When fat cells are broken down in a fasted state, they release toxins. These toxins then need to be mobilized and eliminated. If you don’t drink enough water, this doesn’t happen, and the toxins will be recirculated.
Intermittent fasting will also save you time and money. The time-saving factor is actually more significant than you’d think. Imagine how much time you could save every day by not having to buy, prepare, eat, and clean up one less meal. Every aspect of your health can be improved by intermittent fasting.
Intermittent Fasting And Autophagy
The overarching reason intermittent fasting is so amazing for preventing and treating cancer has to do with a process called autophagy. Autophagy is essentially cellular clean-up, where damaged cell parts are recycled and reused, toxins are disposed of, and repair mechanisms initiated.
Autophagy is what allows the body to sustain metabolism during periods of fasting or starvation. Intermittent fasting stimulates autophagy by stressing the cells of the body. Autophagy prevents cancer by recognizing and removing rogue cells.
All cancers stem from cells that have become defective. Autophagy declines with age, leading to more cells that are diseased, dysfunctional or cancerous. Intermittent fasting, because of its ability to stimulate autophagy, can prevent cancer cells from potentially developing. It also frees up vital energy so the immune system can do its job more effectively.
Autophagy And Apoptosis
Is there a relationship between autophagy and apoptosis, a mechanism where unhealthy cells are programmed to die? While there is no clear evidence the two are related, it’s surmised that autophagy may be a mechanism behind this programmed-cell death. Eating, absorbing, digesting, and eliminating food requires a lot of metabolic energy.
This energy is no longer needed in a fasted state, enabling the immune system to better do its job of eliminating cells that could potentially become cancerous. Intermittent fasting is a profound way to heal your body. When used in conjunction with a Ketogenic diet, it’s alchemy. Most people can do at least some form of intermittent fasting, excluding cases of extreme exhaustion.

What Is Dry Fasting?
When most people think of fasting, they associate it with dry fasting, which is abstaining from both food and water. Wet fasting excludes food, but allows water. I’m not a proponent of dry fasting, particularly for cancer, because water is necessary to excrete toxins from the body. Dry fasting, also called absolute or black fasting, is used to enhance spirituality and enlightenment.
Hard dry fasting, is taken to an extreme level, where absolutely no contact with water is allowed. This means no water when brushing your teeth and no showering. There are even retreats that foster this type of fasting. Incidentally, when Jesus fasted for forty days in the wilderness, He did a wet fast. The longest documented dry fast, recorded in The Guinness Book of Records, is 18 days. However, keep in mind, dry fasting is not advised for longer than 24-36 hours.
Benefits Of Dry Fasting
Proponents of dry fasting use it for both acute and chronic degenerative diseases. It stimulates the immune system, purifies the blood, heals the mucosal lining in the GI tract, while activating anti-inflammatory mechanisms. Dry fasting also clears blockages in the blood vessels, eliminates pathogens, and regenerates healthy tissue. It’s similar to “survival of the fittest,” meaning only the healthiest cells survive when they are deprived of food and water.
Compare this to unhealthy and diseased cells, which aren’t so lucky, and are unable to survive extreme conditions, culminating in a process called autolysis. Autolysis, or self-digestion, happens when diseased tissues are destroyed through the action of their own enzymes. Interestingly, autolysis is seen postmortem.
Fasting is a critical aspect of an effective cancer-prevention and therapy protocol. Intermittent fasting, as opposed to wet fasting, can be engaged in long-term, involves a lifestyle change, but offers all the benefits of water fasting. Both are powerful techniques to detoxify the body, reduce insulin levels, balance hormones, prevent chronic disease, and strengthen immunity.
This is what will ultimately enable your body to heal from cancer. If you or someone you love has cancer, please learn more about the benefits of fasting, and incorporate it into your cancer-healing protocol.
