ELI5: Does an overweight person outlast a physically fit person in a starving to death scenario?
gpt
Short answer: probably.

Long answer: it depends on more than just their relative body fat percentages. But, starving to death is not very common outside the developing world and few people there are overweight to begin with.

The nearest common scenario is something like cancer. People who are very thin tend to die more frequently than people who are overweight.  When you have a wasting disease, the more body reserves you have the better, and cancer treatment often interrupts your ability to feed yourself adequately.
