>woman's secondary sexual characteristics get more pronounced when they get fat

False.

Estrogen sends fat to hips, butt, breasts, and upper arms. Men have evolved to detect estrogen status of females.

A high estrogen female (indicating high fertility) will gain fat in these areas. A low estrogen female will gain fat in her mid torso like a male.

There's an insulin element as well but it's complicated.
