Often when people are aware they're being recorded, especially for some kind of production like a podcast that they're accustomed to hearing with edits, they'll make far more umms and ahhs than they would in an ordinary conversation. I think maybe its because they're concentrating on the continuity of their speech? Whatever the reason, I usually just try to get the number of these tics down to a level that sounds like casual conversation. I don't think most listeners notice when the tics are edited out, but a significant number seem to find them annoying enough that some judicious editing improves overall happiness with the production :)
