After puberty, can certain diets, exercise, and/or possible drugs affect masculine/feminine dimorphism in adults? We know dimorphism and/or morphology is a product of genes, but to what extent can this be altered through environment? Like, can chewing more give a more masculine jaw shape/angle? Can talking a certain way make a more deep, manlier voice? Can squinting give hunter eyes?
For women, can eating soy-based products increase hip-to-waist ratio? Estradiol? Feminization of the face, cheeks and etc.? Likewise, in males, can vigorous exercise, drugs/diet and etc. masculinize?
Sexual dimorphism I mean as in how they look and what makes assure genetic/reproductive value.
Aside from genes, basically, what extent can diet, foods, exercise and etc. affect epigenetics, morphology and sexual dimorphism in animals, namely humans? Any evidence/studies/work on this?
This isn't intended to be a medical/personal question thing -- more so, broad on any means a human and/or animal may use their environment to try and improve dimorphism and morphology/phenotype.
