Intermittent fasting is probably fine as long as you only have an hour or less of exertion on that day. Do 2+ hours though and I think it's a pretty bad idea.

And in my experience even just doing an hour of exercise in a fasted state can dramatically impair my immune system as well as higher brain function.
- rthomas6 8y agoI don't know 100% for sure, but I think this may have more to do with how many calories you're eating over time total vs how much you eat near exercising. A caloric deficit on its own will do all the things you've named regardless of feed windows, and I haven't experienced any of them while intermittent fasting. But I can't say for sure if I've ever had 2+ hours heavy exertion while doing IF.
