>I’d be more concerned about water TBH. Most of us carry a fair amount of fat, enough to survive several weeks without eating.

They used to call it "the law of twos" - you can live two minutes without air, two days without water, and two weeks without food.

So yeah, water is the big concern. Two weeks without food is the low end, but electrolyte imbalances can kill you even if you still retain plenty of stored calories.
