The overweight but otherwise healthy individual will last longer in crisis situations. I'm about 60 lbs. overweight, which translates to around 3 months of caloric reserves (likely an unhealthy amount TBH).

Before industrialization, being overweight was seen as a mark of beauty and wealth regardless of gender.

(Not a rationalization for being unfit or unhealthy when taken to extremes.)
