    The metabolically obese normal weight (MONW) phenotype in children can lead to increased cardiometabolic risks despite normal BMI.

  • 2

    Prevalence of MONW in children ranges from 10.6% to 56.2%, influenced by varying diagnostic criteria and population characteristics.

  • 3

    Children with MONW exhibit higher visceral adiposity, insulin resistance, dyslipidaemia, and low-grade inflammation despite normal BMI.

  • 4

    Early-life determinants of MONW include extremes of birth weight, rapid infant weight gain, and unhealthy dietary patterns.

  • 5

    The review emphasizes the need for harmonized definitions of MONW and suggests integrating metabolic assessments beyond BMI for screening.
