Thank you all for giving me your thoughts on magic systems and where the energy comes from!

I just started reading Hunter by Mercedes Lackey (it came out a couple days ago), and there’s a passage that *directly* states using magic burns “like a zillion calories” like “running two marathons uphill both ways with a backpack of bricks” and describes an immensely satisfying steak. Of course that was a larger than normal output.

I love it when timing works out that way.
