Abstract

Context: The prevalence of diabetes is increasing throughout Asia, even in the absence of obesity, and is lower in women than in men. The underlying mechanisms are not well understood. Objective: To evaluate the sex differences in glucose and fatty acid metabolism in Asians who are nonobese. Design: Cross-sectional study. Setting: Clinical Nutrition Research Centre, Singapore. Participants: Healthy Asian men (n = 32; body mass index, 21.8 ± 1.5 kg/m2; age, 42 ± 14 years) and women (n = 28; body mass index, 21.4 ± 2.0 kg/m2; age, 41 ± 13 years). Main Outcome Measures: Insulin sensitivity (insulin-mediated glucose uptake normalized for steady-state insulin; hyperinsulinemic-euglycemic clamp), postprandial glucose, insulin and fatty acid concentrations, insulin secretion (mixed meal tolerance test with mathematical modeling), insulin clearance, body composition and fat distribution (dual-energy X-ray absorptiometry, MRI, and spectroscopy), cardiorespiratory fitness (maximal oxygen uptake; graded exercise test), and handgrip strength (dynamometry). Results: Women had more total body fat but less visceral fat than men; liver and muscle lipid contents were not different. Maximal oxygen uptake and handgrip strength were lower in women than men. The postprandial glucose concentrations were ~8% lower, the insulin-mediated glucose uptake was ~16% greater, and the meal-induced suppression of fatty acid concentrations was significantly greater in women than in men (P < 0.05 for all). However, muscle insulin sensitivity was not different between the sexes. No differences were found in postprandial insulin secretion and clearance rates; however, the steady-state insulin clearance was ~17% lower in women. Conclusions: Asian women who are nonobese are more insulin-sensitive than men at the level of adipose tissue but not skeletal muscle. Therefore, sex differences in glucose tolerance are likely the result of sexual dimorphism in hepatic insulin action.

  • Triple tracer studies reported sex differences in rates of meal glucose appearance and disappearance and endogenous glucose production in response to a 10 kcal/kg standardized mixed meal.

    “Other investigators have used sophisticated triple tracer techniques (that includes glucose tracers in the meal) to study postprandial glucose metabolism (155, 156); sex-differences in the rates of meal glucose appearance and disappearance, endogenous glucose production, in response to a 10 kcal/kg standardized mixed meal were reported.”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [155]

    The Results section reports a sex difference in postprandial glucose AUC after a mixed meal. But the Mixed meal tolerance test section specifies a fixed 600-kcal meal, not 10 kcal/kg, and describes measurements of glucose, C-peptide, and insulin rather than a triple-tracer assessment of meal glucose appearance, disappearance, and endogenous glucose production.

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.
