Intermittent fasting before Chemo?

I did AC chemo, and the most important thing for any chemo is to stay hydrated. Water has no calories, so that's typically acceptable during intermittent fasting. However, during chemo, I grew to loathe water, and stayed hydrated with anything that tasted good to me. That included broth, soup, and some low-calorie drinks so intermittent fasting wasn't possible for me.

I guess as long as you stay hydrated, intermittent fasting is probably OK. But, I didn't really have any serious gastrointestinal side effects, other than heartburn, while on AC (and that was just the first round). My biggest problem was chemo brain, and I don't think diet would really help with that. Good luck!

I had a bad time during pregnancy and did get nauseous with chemo, but the drugs they provided were enough to keep it to just "mild nausea". Some of those chemo drugs cause a lot of diarrhea too. The drugs they have do lessen symptoms, however. That does not mean I felt good overall, but it made it "doable" as they say. Barring anything rare and unusual, you can and will get though it!

I did try intermittent fasting well into chemo, as I hadn't heard of it until I was done with the AC, I think. Did it mostly for the Taxol. I can't say if it helped with side effects or not, since I started doing it at the same time I started getting the second drug. I also don't know if it helped kill more cancer cells, but research seems to suggest it does help the chemo kill more cells, in addition to aiding with side effects. Chemo is no walk in the park, but with the drugs they have available now for the nausea, etc. it is manageable for most. I hated the idea of taking any drugs - the prescription stuff or the over the counter things, but all in all it worked out, and you only have to take those things for a relatively short period of time. I've actually continued with the intermittent fasting well after chemo. I try to eat within an 8 or 9 hour window each day. How much it is really helping I'll never really know, but I like to think that based on what I've read it continues to help with my overall health and anti-cancer efforts. I'm only about 2 to 2 1/2 years out from my diagnosis, but so far, so good (knock on wood and fingers crossed that it continues this way). I really hope it all goes well for you!
