The current crop of 25-35 year olds were by and large failed by the parents and education systems and were not taught the basics of stocking a pantry/kitchen staples, preparing meals and associated time management e.g. if you want food go get some highly processed crap out of a wrapper. As a result the 10-20 year olds are increasingly dependant on calorically dense but nutrient poor food choices. Masculinasation and fattening of women is partly related to the above and the 'Girl Power' vibe of the 90s going past the point it should have stopped (but lets keep going and see what happens anyway...cue Tess Hollandaise becoming an aspirational figure). In terms of maturation, menarche/ovary activation is triggered by body fat influenced hormone levels ergo there is a link between women started their periods earlier in life and the general fattening of younger generations. Obesity is closesly related to PCOS (as a lifestyle induced thing rather than shitty luck of the draw genetically), Feminisation of men I think is partly nurture, google the phrase "pathologising of male behavior" but also hormonal - fat produces an enzyme called aromatase, it converts testosterone into estrodial or simply, female hormone. Most of the conversion that's supposed to happen does happen in the testes, but it's fat produced aromatase on free testosterone as it's circulating around the body that is the concern. To be male and obese around puberty is to play russian roulette with reaching your individual potential in terms of physical development The individual pictured is probably male, I've rarely observed cargo pants to be a typical style/fashion choice for women, abscence of printing from a bra strap through the t-shirt (or rolls being cut into and leaving a funny pattern in the shirt), hair cut strikes me as more typically male rather than a 'boyish' cut on a woman.
