ELI5: Are there any biological advantages to being overweight? Could it allow you to survive longer without food?

That is the advantage, yes. Scientists believe the reason why humans evolved to store excess food as fat is that it allowed people to survive times of famine easier by having reserve energy. The issue is that our bodies were optimized for lifestyles where the idea of having plenty to eat all year round wasn't possible.
