At any level of adiposity, relatively elevated leptin concentrations are associated with decreased insulin sensitivity

Leptin Levels and Glucose Homeostasis: Insights from the RISC Study

A recent study explores the role of leptin levels in glucose homeostasis among individuals with similar degrees of adiposity. Analyzing data from 1,290 healthy adults in the RISC study cohort, researchers categorized individuals based on their leptin levels relative to fat mass.

Key Findings

• Despite similar glucose tolerance levels, the high leptin group had significantly higher insulin concentrations and secretions.
• The high leptin group showed lower insulin sensitivity throughout their bodies and in adipose tissues, regardless of BMI.

Conclusion

Individuals with higher leptin levels for their fat mass experience increased insulin resistance and hyperinsulinemia, independent of their Body Mass Index.
