Fasting and Cancer: Is It Beneficial Or Not
Looks like good information to me. Here’s two excerpts
———————
You’ve probably seen it all over your feed: claims that fasting can “starve cancer cells” or boost treatment results. But then you read something else that says fasting during treatment is dangerous.
It’s exhausting trying to figure out what’s true, especially when you just want to do everything right to stay healthy and keep cancer away.
The truth is, fasting and cancer is way more complicated than social media makes it seem. Some research looks promising, but other studies raise serious red flags.
As your oncology dietitian, I’m here to cut through the noise and give you the real science so you can make informed decisions about your health without the fear and confusion.

WHEN FASTING BECOMES DANGEROUS
Fasting during active cancer treatment can lead to:
Accelerated muscle wasting: Your body breaks down healthy tissue, including heart and skeletal muscle, to meet energy needs
Weakened immune system: Nutritional deficiencies impair your body’s ability to fight infections and recover from treatment
Treatment delays and interruptions: Malnourished patients often become too weak to continue chemotherapy or radiation at full doses, which can reduce treatment effectiveness
Reduced treatment tolerance: Poor nutritional status increases the severity of side effects and complications
Longer hospital stays: Malnutrition is associated with more infections and slower healing after surgery
A systematic review of fasting in cancer patients emphasized that while fasting-mimicking diets may have some applications, fasting should only be attempted under strict medical supervision.
The risk of exacerbating malnutrition, especially in patients with aggressive cancers or those already experiencing weight loss, is simply too high.
