It's a YMMV kind of thing. I don't like to lift if I feel hungry. Whether being hungry impacts what I can physical do in the gym, I don't know or care. What matters more to me is how I feel mentally. Also, I would not attempt a long bike ride (three or more hours) without having something to eat and drink. Of course, I'm not going to gorge before either activity. |

Of course, I'm not going to gorge before either activity. I find that my lifts are stronger when I'm not hungry. I don't like to have a big meal close to the time I lift, but something a few hours before has a positive effect on my strength and energy. (The energy thing is more apparent for Olympic lifting.) As far as cardio goes, I don't like to be too full doing it, but if I've eaten nothing for hours I tend to get lightheaded. I agree that this is a YMMV thing. Chris |

Experiment: Do we need eating before exercising
Hello Ignor,
You should be a scientist...lol. Your setting up experiments and putting them to the test. All I know is during my time in the Army and Marines we always exercised before breakfast. You always knew the ones who ate before they exercised, they were the ones throwing up during the runs. I think as long as you can handle the food in your stomach during exercise then it's ok. I don't know if food in your system aids someone in exercising harder or not. I've never fasted before except for medical reasons. I don't know how you can fast so long. Way to go on walking to work. We should all follow your example, except it's hard if you work many miles from home. I've been walking approximately 20 miles a week, so I'm getting my exercise out of the way. Take care, Paul 300/235/175 "Ignoramus30622" wrote in message ... Some people think that we need to eat before relatively modest weightlifting or cardio. My personal feeling, after reading some navy seal training books etc, was that it was a false theory and that as long as we eat reasonably, we should not worry about eating immediately before exercising. Since I decided to try fasting once per week for a little while, I decided to test this theory. So, this Thursday I did not eat anything. This means that there was about 38 hours before my last meal on Wednesday and my first meal on Friday. As an aside, I felt pretty good throughout my fast and I was not miserable at all. So, this morning, after not eating anything on Thursday, I did my usual resistance exercises, consisting of pullups, pushups, weighted situps, crunches, deadlifts, dumbbells, etc. Then I walked to work (40+10 minutes). None of these activities was impaired by the fact that for the last 36 hours, I did not eat anything. In fact, I felt that some exercises were even easier for me, namely pullups and weighted situps. That means there is at least one datapoint refuting the theory that it is important to eat something before modest exercise. I will try running after a fast next week, since I cannot run right now (a minor knee injury). As a clarification, obviously there is a point beyond which a prolonged fast would impair exercise performance. Also, before doing truly heavy exrcises like running marathons etc, eating before exercise may be important. But for a regular dude like me, doing his morning stuff, eating before exercise does not seem like it's important at all. I do not fast to lose weight, as such. I just read some convincing things that suggest that occasional fasting may make one feel better. It is an experiment at this point, I will try it for a few weeks and then check if there is anything good that I get out of it. i |

This question is regularly discussed in misc.fitness.weights, and fasting is a topic oft discussed in sci.life-extension. I do not feel that my xpost was inappropriate. The thing is - the groups tend to be conflicting at times, and you tend to start flame wars and lots of unwanted traffic in ASD. Which of course, just ****es people off towards you. Its common curtousy. Cross posting is never acceptable and considered one of the rudest of behaviors. I would except nothing else from the RI (Resident Idiot). Martha |
