Please read more about fasting prior to chemotherapy drugs that usually make you sick with nausea and vomiting and are followed by other things such as mouth sores or mucousitis. This worked for my son who without fasting had Emend and steroids and zofran and ativan but still threw up 5-8/day before fasting. With fasting he threw up ZERO!
HERE IS ONE ARTICLE:
Fasting can protect cells from stress and damage, such as oxidation or radiation, and has been found to protect healthy cells from chemotherapy. But can the practice also help fight cancer?
There is now evidence to support this idea, from research on cancer models of yeast and tumor-ridden mice, published today (February 8) in Science Translational Medicine. Starved organisms survived longer when treated with chemotherapy than those on a normal diet, and healthy cells were less likely to sustain damage.
“This ability to think about adding fasting in combination with chemotherapy is obviously exciting, and it definitely adds something to the arsenal of what we can do,” said Trudy Oliver, who researches cancer resistance at the University of Utah but was not involved in the study.
Chemotherapy works by attacking rapidly dividing cells, a hallmark of cancer. Previous studies suggested that fasting before treatment could help protect healthy cells by slowing their growth even further. But one question loomed in researchers’ minds: “What happens to the cancer cells?” said study co-author Valter Longo, who studies the molecular mechanisms of aging at the University of Southern California. If fasting slowed down cancer cell growth enough to reduce the effectiveness of chemotherapy, “this would be a problem.”
Initial results in cancer-mimic yeast and cancerous mammalian cell lines provided Longo with evidence that starvation slows cancer growth and also enhances healthy cell survival when faced with chemotherapy. These results encouraged Longo to move into mouse models. “If it doesn’t change from yeast to mammalian cells, we figured that it is something so conserved and fundamental it’s going to apply to humans too,” he said.
Longo\’s team studied a variety of mouse models. Mice were injected with both human and mouse cancers, including breast cancer, melanoma, and the nervous system cancer neuroblastoma, among others. The researchers also tested several types of chemotherapy drugs. And each experimental combination was subjected to three treatments: just fasting, by being given only water for 48–60 hours prior to treatment, just chemotherapy, or fasting and chemo together.
Results varied by cancer type and treatment, but overall the combination of fasting and chemotherapy reduced cancer growth significantly, and starved mice survived far longer than their non-starved counterparts. For example, melanoma metastasis was found in 40 percent of mice given just chemotherapy, 20 percent under starving conditions alone, and 10 percent of mice that underwent chemotherapy and fasting.
“The surprising part was that, for several cancers including breast cancer, fasting cycles alone were as good as chemotherapy,” said Longo. “We expected some delay but not an equivalent effect.”
Gene expression assays and molecular analyses suggested that, in cancer cells but not healthy cells, fasting and chemo together induce a 20-fold increase in DNA damage, an increase in oxidative stress, and higher incidence of cleaved caspase 3, a protein that induces cell death.
Longo hypothesizes that, while normal cells are well-equipped to deal with starvation by slowing their metabolism to just essential activities, cancer cells “became better at growing and growing and worse at adapting to new conditions.” When cancerous cells are faced with a hostile environment, such as starvation, they become weak and shut down. “And, when they become weak, chemotherapy has an easier time,” he added. However, he emphasized, this is still a hypothesis.
While Oliver finds the results “provocative,” she would like to see the molecular mechanisms fleshed out more, especially because the pathway is so “counter-intuitive.”
“You might think it would work the other way: that chemo is not going to work as well anymore if you slow down cancer growth,” she said. Future studies should try to elucidate the mechanism and study the phenomenon in more in vivo cancer models to “show us the effect directly on proliferation as a result of that fasting,” she added.
There are already three clinical trials— one of which is at the University of Southern California—underway studying the combination of fasting and chemotherapy in human patients.
Longo suspects that the human equivalent of 48–60 hours of mouse fasting is about five days, based on glucose and growth factor concentrations. Five days is a long time, noted Oliver, and fasting “may be rough for cancer patients who are already going through a lot.” But uncovering the mechanism could lead to better solution, she added.
“It might be that people don’t need to starve to do the same thing, if they can take a new drug with chemotherapy that mimics starvation but is not as painful as starvation,” Oliver said. “That underscores the importance of finding the mechanism.”

My name is Caleb. I’m 17, and I have Leukemia. I was diagnosed almost a month ago now, and I’m starting my Chemotherapy. Yesterday afternoon, I started my second round.
Thank God the first round was easy on me. This second round is really kicking my butt.
I didn’t feel really well yesterday morning, anyways. And I had the option of either having the treatment this morning, or yesterday afternoon at 4, and I opted for yesterday afternoon, because I had a track meet this morning.
I got there around 4:00, and they hooked me up. I sat in the seat, and waited for it to finish dripping.
Halfway through, I got a HUGE headache. I mean, this was the worst pain I’ve ever had in my head. It felt like someone was hitting me in the head with a hammer.
I finished and went home about 2 hours later, after talking to some really close friends in the treatment place.
I got home, and went to lie down and watch a movie. My head was still pounding.
This morning, I woke up, and automatically felt sick. I stood up, and I was extremely dizzy. I spent the better part of the morning in and out of the restroom, and sleeping on the bathroom floor. I hate that.
I was usually pretty healthy. I never got sick before all of this happened, and I’m not used to it. I don’t like it.
After my numerous restroom trips, I finally worked up enough strength to make it down stairs to say good morning to my amazing mother, and I sat down at the kitchen table, and laid my head down. My mom felt my forehead, and took my temp and all that. Granted- she’s not used to this quite yet, either. She’s used to healthy kids, I mean, none of my 5 brothers have ever had anything that compares to this, and neither has my sister. Quite frankly, neither have I. She’s not very fond of us being sick at all, I mean, the flu season is a terrible time for her! I was running a fever of like… 102, I think. And my head was still killing me.
She sent me to lie on the living room couch, and when I laid down, I turned on Fired Up!, and soon fell asleep.
I woke up about an hour later, and I felt a HUGE surge of nausea, and I leapt for the restroom.
See, now, this is where my story gets pretty pitiful. I hate being sick. SO much. I absolutely despise it. But I’m smart enough to expect it with Chemo.
So, I spent a lot of my afternoon throwing up, and falling asleep, and throwing up, and falling asleep again, and on and on.
Needless to say, I didn’t have a very good day.
I hate Chemo treatments.
Who’s with me?
