Section 1.1: The Science Behind Fasting

Fasting may be particularly beneficial for cancer patients because it can initiate autophagy.

What exactly is autophagy?

The term "autophagy" comes from Greek and translates to “self-eating.” According to Dr. Priya Khorana, PhD, from Columbia University, autophagy is the body’s mechanism for disposing of damaged cells. While some might find this unsettling, in Hindu philosophy, destruction is an integral part of creation, symbolized by the deity Shiva, just as Vishnu embodies creation and Brahma represents sustenance.

Through autophagy, the body repurposes materials from destroyed cells to form new, healthy ones.

This process interrupts the roles of mTOR and insulin, which promote cell growth. During fasting, levels of insulin and mTOR decrease, allowing the body to repair itself. To trigger autophagy, a fast of at least 14–16 hours is necessary, with a five-day fast recommended for optimal results.

Moreover, fasting lowers blood glucose levels. Since cancer cells thrive on glucose, reducing its availability may help inhibit cancer growth.

However, for cancer patients, it’s crucial to balance various needs. Prolonged fasting could pose risks for many, but many can safely fast for 16–18 hours while still obtaining necessary nutrition. Given the unique challenges faced by cancer patients, consulting a healthcare professional and a nutritionist is essential.

Fortunately, for those unable to fast safely, a “fast-mimicking” diet is an alternative.

This diet aims to replicate the effects of fasting while allowing for approximately 40% of normal caloric intake. Ideally, it should be higher in fats and lower in carbohydrates and proteins. The main drawback is that it can be more challenging to adhere to than a complete fast. However, it may be the best option for individuals whose nutrition is already compromised by cancer treatments like chemotherapy.

For my part, I began fasting for 16 hours a day during radiation treatment for my lung cancer. The outcomes have been encouraging. My CT scans indicated a reduction in lung cancer size during treatment, and two months post-treatment, it remains stable.

I had intended to try a 48-hour extended fast, but after 20 hours, I felt extremely weak and decided to break it.

Listening to my body is vital. However, I plan to attempt a two-day fast again after the New Year. If successful, I might consider a longer three-to-four-day fast. I am committed to regularly checking my blood levels and ensuring I consume nutritious foods.

I will keep everyone posted on my journey to share the results of this self-experimentation.
