>>81857163>visceral fat You are right on the basic facts, but wrong about the direction of the causal arrow.
It is true that, for the median woman's biology, "more visceral fat => more breast".
It is not necessarily true that "more breasts => more visceral fat".
Breast composition differs woman-to-woman and also consists of glandular tissue and connective tissue. The ratios between these can be so wildly different between premenopausal women that sometimes you can easily see the differences in medical imaging (or feel them easily with your hands ರ‿ರ). It is also an understudied area of human physiology. Nobody funds studies of "What do big tiddies mean for long-term health outcomes?", so funding for many of the studies about breast composition are under the guise of breast-cancer-adjacent topics.
