A Day Without Food

I started feeling a bit ill late Friday, so I decided to do a water-only fast on Saturday.  Generally, animals fast when ill, and I try to follow this model.  I also skipped breakfast and lunch on Sunday, and so I ended up going without food for around 40 hours. 


This is interesting for me, because a few years ago I wouldn’t have been comfortable going without food for this long.  I wouldn’t have voluntarily have gone without food for a day, and not when I was ill, either.  However, this fast was fairly painless, as I didn’t have much of an appetite over the weekend to begin with.


It’s amazing what the body can do when it has to.  I’ve read research on subjects doing a water-only fast for 30 days without any negative effects (not that I would recommend this!).  When food isn’t available, the body simply draws energy from stored body fat and other sources.

    Indians in the Pacific NW used to fast as a first line of defense against illness. I fast when I’m sick as well. It seems to help me get well faster. Did your fast help you recover?

    Definitely. It seems to cut the duration of a cold to 3-4 days instead of 7 to 10.

    Very interesting, I’m going to have to try this. The thing is, I don’t really get sick anymore eating the way I (and you) do–veggies, meats, fruits. I used to get a cold from about October till May, but the past year or two since eating this way, I don’t think I’ve gotten a cold.

    I’ve done fasts in the past for periods lasting 18-24 hours…

    definitely a good natural way to detox. Although I never did get used to the feeling of running completely on ‘empty’, it did really put me in tune with my body’s physiology.

    A great post and an experience I too have had. I went ‘Paleo’ with my nutrition a couple of years ago, and since doing so, have found that I CAN ‘fast’. This would have been something I would not even have contemplated in my days as a ‘low-fat carbinator’. I blogged about it here:

    Hey Matt,

    Glad it worked for you. I have been doing IF for around 2-3 months now. I do an 18hr fast and 2 24hr fasts that bracket the weekend. There have been a couple of time I felt a cold coming on but it passed in 18 hours or so instead of putting me in bed for a day or two. Anecdotaly it helped. I starting eating 95% Paleo since February, which probably helps as well.

    Keep up the excellent posts. I read every one.
