Can I heal myself with a 3-day fast?

Publishing this post is the hardest thing I will do all day because now that I’ve written it down and sent it out to the world, I have to do what I’m about to say…or have a damn good excuse why not.


In a previous post, I mentioned that I was considering a 3-day fast. I believe the time has come to stop considering it and actually do it.


I knew you would ask.

Let me start with the problem that I’m having: gastritis. It’s inflammation of the stomach lining and it sucks. It’s usually caused by an infection, but I don’t have one. I do have reflux, but I couldn’t get a clear answer from the doctor as to whether or not that is causing this problem. She put me on a soft diet and told me to take Prilosec for 2 weeks, but that did NOTHING. I felt better for a little while but here I am again, in pain.

Fasting does help me feel better, especially the day after the fast. My stomach feels more relaxed because I’m still eating light, but then when I go out to dinner later in the week I go back to square one and have pain again. I can’t live like this: stuck between only eating food that doesn’t need to be chewed or being in intense pain.

One of the reasons I started intermittent fasting was because of the healing properties of fasting. You can find the scientific research to back up this claim in The FastDiet, but the simplest way I can summarize it is like this: Most of our immune system lives in the gut (intestines and such) and if we constantly bombard the gut with food to digest, then it doesn’t have time to heal whatever is wrong in our bodies. When we fast, we give our bodies a rest from digesting all the stuff we eat (difficult considering all the processed food in our diets) which frees it up to start repairing our damaged cells.

In the book, Dr. Mosley started his fasting journey with a 4-day fast under the supervision of Valter Longo at USC. He has published studies about how fasting for a few days can reset parts of the immune system. Is this what I need? I don’t know. What I do know is that fasting for a day makes me feel better. So I hope fasting for 3 days will give my body more time to heal.

Obviously the whole process will take more than 3 days. I’m planning a pre-fast cleansing day and a few recovery days after the fast. I’m going to blog about it everyday so you will know if I survive each day and so you can witness this human experiment in progress.

And it starts Monday.

    I’m not sure what you mean by “most of our immune system lives in the gut.” Our lymph nodes (located throughout the body, the spleen, bone marrow, thymus, lymphocytes, and leukocytes are the major components comprising the immune system. TY Carol, RN

      Hi Carol!

      I realize I over-simplified it, but I try to keep these posts short so that people will read the whole thing.
      Here is a study that is boring and scientific, but it says gut-associated lymphoid tissue makes up 70% of our immune system:

      Thanks for asking and I will edit the post to include a link to an article I found that might explain it better than I can, but in simpler terms than scientists use 🙂
