Here's what I think -- since you are now Gnat Man, having undergone radiation for the bug in your brain, you can only eat lizards and frogs after they're dead, as you're now a carrion eater. Seconding Greenlydia, Bon Appetite.
If wondering about eating frogs and lizards is causing you anxiety.............don't eat them. (Or direct your post to the kitchens of Martha Stewart)
No frogs/No Lizards=No Anxiety.
