Fasting and physical activity

Answered on August 19, 2014

Hey guys! So, I've been thinking about implementing IF into my routine. I'm thinking something like a 16 to 24 hour fast every 7 to 10 days...just to give my gut a break. However, I am very active. I ride my bike to work, engage in lots of play, etc. My question is, on days that I fast should I avoid any physical activity? I'm concerned about not having enough fuel to be able to perform any of the activities that I regularly do. Could I do more harm than good by doing physical activities on a fast day? Any advice is appreciated!

I think he will be fine if the activity he does while fasting is low intensity stuff, aerobic exercise. As long as he does not need to enter the glycolithic pathway I think it can be doable without putting much stress. I also think this will even bring him into a better fat adapted individual in less time. But as for football and general play where intensity is random I also think he'd be safest by eating something 2-3h before as the stressful response might be too much if he goes into high-intensity exercise. In both cases I'd re-feed ASAP after exercise. And yes, if feeling bad, eat! hehe

You will likely be AOK for 1 fast per week.

If you are cycling 2 hours each way to work, you may want to reconsider the fast. Otherwise, there's plenty of fat stores and liver & muscle glycogen to carry you through, and not waste muscle.

If you try, and you find yourself light headed or nauseous, then just eat something.

Well, there are a whole different group of people that fast- religious people. Those people notice that exercise can actually help. They get tired, grumpy, or whatever, and go take a walk or something. Exercise usually raises blood sugar to some extent.

So, don't go do anything crazy, but don't just still still in your house all day either.
