Occasional fasting can reduce the side effects of chemotherapy?

 Professor Walter Longo, a cancer scientist in the United States, discovered after personal experience that scientific “fasting” can effectively reduce the side effects of chemotherapy. The fast here is “short-term hunger” and lasts only a few days. Note that long-term fasting and starvation may cause irreversible damage to the human body.
  The researchers fasted the mice for 48 hours before using high-dose chemotherapy etoposide (80 mg/kg). Ten of the 23 mice that did not fast all died from the toxicity of chemotherapy. The mice that survived without fasting also showed symptoms of poisoning: inconvenience in movement, hair erection and hunchback. Of the fasted mice, only one out of 17 died. And these fasting mice showed no signs of anxiety or pain. Does occasional fasting really help cancer treatment? How to do it?
  Intermittent fasting advocate
  of correspondents: fasting help reduce chemotherapy side effects?
  He Yumin: According to this study, fasting can indeed reduce the side effects and mortality of chemotherapeutic drugs on experimental rats, and can improve the immunity of elderly rats. However, it is especially important to note that fasting must be controlled well and must not be carried out blindly.
  Journalist: What should I do?
  He Yumin: At present, the three most widely studied fasting schemes are fasting every other day, 5:2 intermittent fasting (fasting 2 days a week), and eating for a limited time. For cancer patients, we advocate intermittent fasting, fasting and water for a short period of time during normal diet. The fasting time is usually 24-48 hours. There is no special requirement for the fasting interval between two fastings. -Fast once every 5 days or once a week. The University of Southern California-Norris Comprehensive Cancer Center has conducted tests on the duration of fasting. In patients receiving platinum (cisplatin or carboplatin)-based cocktail chemotherapy, up to 72 hours of fasting (48 hours) (Pre-chemotherapy infusion + post-chemotherapy infusion 24 hours) is considered safe and will not have a significant negative impact on the efficacy of chemotherapy.
  Fasting has drawbacks, not everyone is suitable for
  the correspondents: fasting may bring any harm you? Is it suitable for every cancer patient?
  He Yumin: Not everyone is suitable, such as pregnant or lactating people are not suitable. Diabetics are not suitable, especially patients with type 1 diabetes may be dangerous.
  Although fasting has a positive effect on the treatment of tumors, side effects such as headache, dizziness, nausea and weakness may also be found. Some people may feel hungry at first, especially those who are used to eating breakfast and supper. In addition, there may be several aspects, such as weight. Cancer cachexia is one of the common complications of cancer patients and is considered to be the direct cause of about 20% of cancer deaths. Fasting can reduce lean muscle loss more than calorie restriction.
  In short, it is important to point out that although research shows that “fasting” has a positive significance for the treatment of tumors, whether it can be translated into clinical treatment for tumors needs to be confirmed by more studies. In addition, which patients are suitable and how to scientifically “fast” also requires an oncologist to evaluate according to the patient’s own situation, and must not try it by themselves.
