As an "hour glass" person I can tell you how my fat has always been distributed. When I gain or lose weight, it's as if air is being let out of or added to a balloon. Everything grows or shrinks in tandem.

The biggest difference I've noticed over the years is others' perception of my weight. I weigh about 20 lbs more than they think I do. I guess I carry it differently. I always thought this is because my genes from my paternal side are big, heavy and those from my maternal side are small and light. I'm a short person with heavy bones. IDK what's accurate.
