    Study Notes

    Metabolically Healthy Obesity

    • Individuals with metabolically healthy obesity do not have a higher risk of cardiovascular disease than non-obese individuals.
    • Despite the deleterious metabolic effects of obesity, individuals with metabolically healthy obesity are protected from complications.
    • The worldwide increase in type 2 diabetes, cardiovascular disease, and cancer is linked to the obesity epidemic.

    Key Parameters Defining Metabolically Healthy Obesity

    • Waist Circumference: While BMI and waist circumference are strongly related, waist circumference may be more informative in identifying metabolic risk in normal weight and moderately obese individuals.
    • Physical Fitness: Obese individuals who are physically fit have a lower risk of mortality compared to obese individuals who are unfit.
    • Insulin Resistance: Insulin resistance, measured by HOMA-IR, is strongly associated with BMI but varies significantly among obese individuals.
    • Other Metabolic Risk Factors: Factors like lipid profiles, blood pressure, inflammation, and physical fitness can contribute to understanding metabolically healthy obesity.

    Evidence from Prospective Studies

    • Studies have shown that obese individuals with a metabolically healthy phenotype have lower mortality risk compared to obese individuals with a metabolically unhealthy phenotype.

    Key Studies and Findings

    • Studies using insulin resistance: Found that individuals with high insulin resistance (HOMA-IR ≥ 2.5) had a higher mortality and cardiovascular disease risk compared to those with lower insulin resistance.
    • Studies using cardiorespiratory fitness: Showed that obese individuals with good cardiorespiratory fitness had lower mortality and cardiovascular disease risk compared to obese individuals with poor fitness.

    Figure 2

    • Shows the relationship between BMI, waist circumference, and insulin resistance.
    • Illustrates that while waist circumference and BMI are strongly related, insulin resistance (HOMA-IR) varies significantly at different BMI levels, even among individuals with morbid obesity.
