I agree this worst case is far stretched. If you have invisibility gear, you should have some of the other satiation options open to you.
The case I needed this info was more something in the middle of those case :
- strained : early game I find myself strained a lot due to inability to try out equipment
- I'll have no artifacts
- It will happen during a minor vault clearing, or the top of the pyramid fight where fleeing to safety for eating is not really an option.
