ELI5 why overweight people (whether due to health or bad habits) bulk up in the midsection of their bodies from a biological point of view, even though they gain weight everywhere else in their body as well?

Well not all overweight people bulk up in their midsection. There are Android and gynecoid body types with regard to fat distribution. Android is what you are describing - where a person can have skinny legs, flat ass, but a disproportionately bigger stomach. Gynecoid, you will see smaller waist, with fat mainly collecting in the hips, thighs, buttocks. More common in women. It’s your genetics. This being said, high stress (high cortisol levels) can be another predisposing reason for fat collecting specifically on the abdomen.
