I wouldn't call protein breakdown in the muscle "wasting" without additional effects

Fair enough, given it's voluntary [1]. It's biologically identical to wasting, however.

There's some evidence that exercising during the fast helps minimize the loss of muscle.

The original point was autophagy reactivates mTOR. This isn’t a linear system. It could be that a 20-hour fast downregulates mTOR more than a 30-hour fast. (We know it works at 72 hours.)
