I certainly agree with the comments about different types of fasting and possible benefits (depending on individual circumstances, situations, risk factors and so on).
It was not my intention to totally disregard the practice on an overall basis. It may be fine for some for a couple of days. In fact, my mother does some sort of 24-hour juice fast every three months or so and she believes that it assists to flush the toxins from her body, so hopefully it is of some assistance to her and others. She is in her late 60's and in great physical condition and can safely utilize short fasting experiments.
My point is that combining running with fasting (for an extended period of time) might be dangerous and certainly would not be recommended for most due to the obvious, potential health complications. I am not closed-minded to the idea on a limited, monitored basis. I am not a candidate for attempting any type of fast because I am severly hypoglycemic and have to utilize strict dietary methods to store more glycogen.
Hope this better clarifies my position. I do understand different diets and nutrition methods may or may not be appropriate based upon personal considerations.
I am in with Jasko123, a Hypoglycemic Runner. So you see why we are partial. When I saw this thread, I surley had to read up. I agree with NOT doing this for a prolonged period of time. I think you could end up doing some major damage to your health. If you are a lean runner and not eating enough or the correct food for your type of workouts, it could deplete your Blood Glucose levels, not pretty. I know 1st hand. Not from fasting but from not eating correctly for so many years around my runs. Fasting and working out is usually for people with more stored body fat , not for leaner people. That is why many trying to loose weight do it first thing in the morning. I would not recommend this if you do not know what you are doing or if you have underlying health conditions.
That's right! I totally agree with you born2run61.
Hey mpsfamily, I understand that there can be useful benefits in fasting, but is it all worth it? To be honest, it's my first time to hear someone tried going on fasting while running. You need food to keep you energized so I don't quite understand how it all works.
How was it? Did you feel any bad side effects? How about the good side of it? Were there any changes/improvements in your skills?
apuramedia- I wrote fairly detailed posts for each day of the fast and two posts about the aftermath. http://michaelselmer.wordpress.com/category/fasting-and-health/
Briefly, all I can say is that it works for me. The negative side-effects were temporary and minor and are detailed in the posts. Although I experienced many benefits, the one that I appreciated the most was the relief I felt from my arthritis in my hands and ankles. It vanished late in the fast and it was several months before I felt any discomfort in my joints as the arthritis returned. It is only now (after 5 months) begininng to return to the previous level of discomfort as before the fast. It seems to me that my body was cleansing the junk out of my system, including my joints. This same relief was experienced when I did a ten-day fast a little over a year ago. I tried a five-day fast (ran through that also) a short time ago and it wasn't long enough to cause much benefit. I plan to continue doing 10-days a couple of times a year. There are studies that indicate regular fasting can extend life span. I'm not interested in doing it if it negatively impacts my quality of life, but I don't feel that it has.
All the negative or doubtful comments have come from people who haven't tried it. I've been unable to find any overall negative comments on the internet from someone who has actually done a long fast. Of course there are discomforts ... even risks ... but for the some people, I think fasting would be very beneficial.
DON'T try it without study first.
