Question 1

What is the Meaning of Ketogenic Diet in Oncology?

Accepted Answer

The application of a Ketogenic Diet (KD) within an oncology setting as a metabolic adjuvant therapy, characterized by very low carbohydrate, moderate protein, and high fat intake. This dietary approach aims to induce a state of nutritional ketosis, fundamentally altering the systemic metabolic environment to one that is less favorable for cancer cell proliferation. While not a standalone cure, the KD is explored for its potential to sensitize tumor cells to conventional treatments and improve the patient's overall metabolic health. It is a targeted nutritional strategy focusing on the metabolic vulnerabilities of cancer.

Question 2

What is the Origin of Ketogenic Diet in Oncology?

Accepted Answer

The concept stems from the Warburg Effect, the observation that many cancer cells preferentially utilize glycolysis for energy, even in the presence of sufficient oxygen, a phenomenon termed aerobic glycolysis. The KD was first explored in the 1920s as a therapy for epilepsy, but its modern application in oncology gained traction by exploiting the metabolic differences between healthy and cancerous cells. Current research focuses on the therapeutic potential of ketone bodies as an alternative fuel source for normal tissues.

Question 3

What is the Mechanism of Ketogenic Diet in Oncology?

Accepted Answer

The primary mechanism involves severely restricting glucose availability, the preferred fuel for many aggressive tumors, and increasing the production of ketone bodies, such as beta-hydroxybutyrate (BHB). This metabolic shift creates a state of "metabolic stress" for the cancer cell, simultaneously suppressing the pro-growth Insulin/IGF-1 signaling pathway. Furthermore, BHB may directly modulate gene expression and enhance mitochondrial function in healthy cells, potentially increasing the tumor's susceptibility to chemotherapy and radiation.
