I worked with a lot of women for years in banking. After like 22 they were just getting bigger and bigger at a terrifying rate. They were out eating me every meal.
There was a few high IQ women(usually Northwest European or Asians ethnically) who made a tremendous effort & dedication and managed to stay slim. But that was not the norm. (And I am talking actual normally slim, like the old 'ideal weight' tables, not the 'new' cucked weight tables.)
You might think these 5'4, 170 lb 'average'(aka 50% are even more obese.. are happy because they can still get laid. Yes on rare occasion they can get a chad or chadlite in a brief relationship. But the thin girls sexual market value mogs the absolute fuck out of a landwhale.
The women were well aware of this reality. Most were always trying to diet.. just women's self control is so low they kept failing, and actually getting bigger over time.
