Gender differences in insulin resistance, body composition, and energy balance

Abstract

Background Men and women differ substantially in regard to degrees of insulin resistance, body composition, and energy balance. Adipose tissue distribution, in particular the presence of elevated visceral and hepatic adiposity, plays a central role in the development of insulin resistance and obesity-related complications.Objective This review summarizes published data on gender differences in insulin resistance, body composition, and energy balance, to provide insight into novel gender-specific avenues of research as well as gender-tailored treatments of insulin resistance, visceral adiposity, and obesity.Methods English-language articles were identified from searches of the PubMed database through November 2008, and by reviewing the references cited in these reports. Searches included combinations of the following terms: gender, sex, insulin resistance, body composition, energy balance, and hepatic adipose tissue.Results For a given body mass index, men were reported to have more lean mass, women to have higher adiposity. Men were also found to have more visceral and hepatic adipose tissue, whereas women had more peripheral or subcutaneous adipose tissue. These differences, as well as differences in sex hormones and adipokines, may contribute to a more insulin-sensitive environment in women than in men. When normalized to kilograms of lean body mass, men and women had similar resting energy expenditure, but physical energy expenditure was more closely related to percent body fat in men than in women.Conclusion Greater amounts of visceral and hepatic adipose tissue, in conjunction with the lack of a possible protective effect of estrogen, may be related to higher insulin resistance in men compared with women.

  • Subcutaneous adipose tissue tends to express aromatase at higher levels compared to visceral adipose tissue, whereas visceral adipose tissue appears to express more 17β-hydroxysteroid dehydrogenase, an enzyme that interconverts E1 and E2.

    “SAT tends to express aromatase in higher levels compared to VAT, whereas VAT appears to express more of 17β-hydroxysteroid dehydrogenase (17β-HSD), an enzyme which interconverts E1 and E2 (191).”

    From Metabolic impact of endogenously produced estrogens by adipose tissue in females and males across the lifespan (2025) · cites this paper as [191]

    The “Depot-Specific Adipose Tissue Sex Steroids” section reports that SAT has relatively more aromatase than 17β-HSD, while VAT has more 17β-HSD than aromatase. Those are comparisons between enzymes within each depot, not direct measurements of each enzyme across SAT and VAT. The section also states that 17β-HSD converts estrone to estradiol, but does not state that the conversion works in both directions. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
