Men and women have about the same number of glucocorticoid receptors in their belly and under-skin fat, so the reason men and women store fat differently isn’t because of how many of these receptors they have.

Assessment Explanation
The claim is based on a direct measurement of receptor density in human adipose tissue across sexes, which is a well-established method in molecular endocrinology. The conclusion that GR density does not explain sex differences in fat metabolism is mechanistic and logically follows if the data show no difference in receptor numbers. However, it assumes that GR density is the primary mechanism — which may overlook downstream signaling or cofactor differences. The claim is appropriately worded as definitive because it is limited to receptor density, not overall metabolic regulation.
More Accurate Statement
“Glucocorticoid receptor density does not differ between men and women in omental or subcutaneous adipose tissue, suggesting that sex-based differences in fat metabolism are unlikely to be driven by differences in receptor abundance.”

Evidence from Studies
Supporting (1)
Characterization of regional and gender differences in glucocorticoid receptors and lipoprotein lipase activity in human adipose tissue.
The study found that men and women have the same number of glucocorticoid receptors in their belly and under-skin fat, so differences in how they store fat aren’t because of these receptors.
