While many people focus on calories or trendy diets, some foods can actively protect the body, while others may silently increase the risk of conditions like cancer.

How intermittent fasting affects cancer
“Intermittent fasting plays an important role in cancer,” says Dr Tarang. He explains, “When you fast, your body and cells get time to heal. During fasting, cells enter a maintenance mode, which helps the immune system function better and removes damaged or negative cells. This repair process is essential for overall health and cellular rejuvenation.”
Addressing a common misconception, Dr Krishna warns, “Many people believe that a ketogenic diet can cure cancer. That’s not true. The body only enters a ketogenic state when it is necessary, and following such a diet blindly can be harmful.”
Is ketogenic diet always safe for cancer
He emphasises the importance of personalised guidance: “Only consider a ketogenic diet if your cell or gene expression indicates it would be beneficial. Half knowledge can be dangerous and may do more harm than good.”
Dr Krishna adds that while intermittent fasting can support cellular repair, immune health, and metabolic balance, it should always be approached thoughtfully. “Incorporating fasting into your routine can be beneficial, but it must be done under professional supervision, especially for individuals with specific health conditions or those undergoing cancer treatment.”
