Fasting May Protect the Body from Chemo Toxins
The old adage “feed a cold, starve a fever” may need be updated to feed a cold, starve a fever—and kill a tumor.
Scientists at the University of Southern California (along with Italian researchers) report today that fasting for 48 hours before receiving chemotherapy could help limit the treatment’s toxic effects to cancer cells—and spare healthy ones. The new finding may pave the way for higher and more frequent chemo doses that better shrink tumors without harming normal cells.
The technique stems from lessons learned during research on aging, according to Valter Longo, a U.S.C. gerontologist and co-author of the new study published in Proceedings of the National Academy of Sciences USA: When normal cells are starved, the body uses up stores of glucose and energy to keep them functioning; in response, the cells shift into survival mode, revving up repair mechanisms and protective processes to resist anything—including potentially fatal drugs—that threaten to damage their genetic material.
“You can think of it as something similar to the fight-or-flight system,” he says. “When you have a dog running after you, the system redirects towards the muscles for running, for instance, and away from the immune system and other normal processes.”
Longo hatched the starvation trick based on his research showing that restricting calories may increase life span. Working with baker’s yeast, he and other researchers found that the fungus sustains less cellular damage as it ages when deprived of key nutrients, allowing it to live longer. Mammalian cells have a version of the genetic pathway that controls this starvation response in yeast. So, Longo decided to exploit a key difference between normal cells and cancerous ones: In tumor cells, these genetic pathways are essentially disabled because the cells are programmed solely to grow and divide. Thus, starving an organism may trigger normal cells to put up their guard, leaving cancer cells to absorb chemotherapy agents.
Indeed, the team found that the chemo drugs were more effective at killing tumor cells, although they left normal cells unharmed. In yeast injected with cancerous cells, for instance, the research team was able to get a chemotherapy agent to knock out 1,000 cancer cells for every one normal cell, compared with a normal one-to-one ratio

In an effort to get a handle on toxicity, researchers starved mice (injected with malignant cells) before giving them megadoses of chemo; the animals lost up to 40 percent of their weight but regained it—and their energy—once treatment ended. What’s more, Longo says, the therapy—three times that considered to be a high human dose—also did not appear to have any toxic side effects. In contrast, when mice on normal diets were given cancer and chemo, they were sapped of energy, did not gain back lost weight, and died much sooner than their fasting peers.
Dr Longo speaks in 2015 on this subject:
Longo estimates that healthy cells in starving mice were five to 10 times more resistant than cancer ones to chemotherapy. “If we can get to 20- or 50-fold,” he says, “we are in a very different position in the fight against in cancer.”
He’s optimistic that researchers can attain that goal with a combination of limited fasting and drugs that kill malignant cells but also prod healthy ones to up their defenses.
Felipe Sierra, a cell biologist at the National Institute on Aging, praised the effort as a new way of attacking cancerous cells by steeling normal ones against the ill effects of chemo (rather than trying to only target malignancies, which is difficult to do). He cautioned that it would only work in patients robust enough to endure two days of fasting before chemotherapy, but noted that many of them are up to task.
But James Harper, a pathologist at the University of Michigan School of Medicine, is skeptical, noting that in some cases mice given chemo andfood actually outlived their starved brethren. “It’s probably a little too early to start jumping up and down” he says, “touting this as a new way to treat cancer.”
Longo agrees that although the technique is not quite ready for prime time, it offers the promise of better treatment. Clinical trials are now underway to test its effectiveness in humans within six months.
Additional ways to protect against toxicity:
Amrit Kalash Nectar or MAK has been proven in studies to protect the body’s healthy cells and as an adjuvant to chemotherapy resulting in less vomiting, the preservation of body weight and a sense of wellbeing, additionally MAK was shown to be effective in reducing toxicity of chemotherapy treatment without impairing the anti-cancer effects of the chemotherapy.
Other methods to help protect the body from toxins is the traditional mustard bath taken a day after a chemotherapy session. This is an ayurvedic treatment you can do at home by soaking in a hot bath of mustard powder. The mustard is what detoxes the body, the hot water opens the pores to allow the healing power of the scents such as Eucalyptus, Rosemary, Thyme and other wintergreen oils. If you want to feel good and detox your body, there is nothing like a good, hot mustard bath, either using your own formula or a just our mustard bath powder which contains the added ingredients.
You can also use the mustard rubbing oil after the bath, which continues the wonderful healing actions. Mustard seeds contain allyl isothiocyanate (AITC). In studies on mice it was shown that the anti-microbial qualities of allyl isothiocyanate significantly reduced ascites secretion and tumor cell proliferation by about 80% and inhibited vascular endothelial growth factor expression and help in the detoxification of the liver. AITC has also been shown to have Anti-Cancer properties.
is based on elements from herbal formulas in traditional Chinese medicine for protecting the vital organs, the bone marrow, liver, kidneys, lung, spleen and to nourish the blood and maintain energy (qi) to the body and support the immune system. Based on the concept that qi and blood deficiency were early adverse effects of chemotherapy drugs, huang qi in this formula was paired with the blood nourishing agents Lycium and Jujube. Since qi and blood deficiency engendered impairment of blood circulation, Angelica and Rehmannia within our tonic are also supportive to . The combination of Ginseng and Lycium for nourishing kidney yin with Turmeric for micro-circulation were expected to help protect bone marrow.
