Decline of mitochondrial fitness in overweight states is a biomarker of the systemic mitObesity syndrome, providing a mechanistic link between common obesity and associated chronic comorbidities.

Body mass excess provides an evidence-based index of underweight, overweight and obesity across all heights and ages, applicable to all populations for which the healthy reference baseline is established.
