Can fasting starve cancer cells to death? A cancer surgeon says it's not that simple.
Intermittent fasting has exploded in popularity in recent years, touted as a panacea for everything from weight loss to chronic disease prevention, even cancer. But here's where it gets controversial: while some claim it can aid in cancer treatment, a leading surgeon is setting the record straight.
Dr. Sudipto De, a robotic cancer surgeon specializing in genetics and onco-nutrition at Metro Hospitals, Delhi NCR, debunks the myth that fasting can selectively target and kill cancer cells during treatment. In a recent Instagram video, he explains the science behind fasting and its limited role in cancer management.
Fasting's Benefits: Prevention, Not Cure
Dr. De acknowledges that intermittent fasting, or time-restricted eating, triggers a process called autophagy, the body's natural waste disposal system. This process can reduce inflammation and potentially prevent abnormal cell growth, which is beneficial for cancer prevention in healthy individuals. Think of it like giving your body a regular tune-up to keep it running smoothly and reduce the risk of future problems.
But here's the crucial distinction: Once cancer has developed, fasting's benefits shift dramatically. Dr. De emphasizes, "You cannot selectively kill cancer cells that have already formed by fasting. These rogue cells are already adept at stealing nutrients from healthy cells, ensuring their own survival during periods of deprivation."
During cancer treatment, the body's needs change drastically. Chemotherapy, surgery, and radiation therapy are grueling processes that demand extra calories, protein, and nutrients. Fasting during this time can lead to malnutrition, weakening the body and potentially hindering treatment effectiveness. Dr. De strongly recommends a dietitian-guided, high-calorie, high-protein diet during treatment, incorporating foods like smoothies, nut butters, eggs, lentils, paneer, avocado, and olive oil.
So, is fasting ever appropriate for cancer patients? Dr. De suggests that occasional fasting, like a 12-14 hour overnight fast, might be beneficial for healthy individuals as a preventative measure. However, for those undergoing cancer treatment, prioritizing proper nutrition is paramount.
This raises important questions: Should we be more cautious about promoting fasting as a universal health solution? How can we ensure that cancer patients receive accurate information about dietary interventions? Let us know your thoughts in the comments below.
