Macro partitioning
Fat Mass Index (FMI) and Android/Gynoid (AG) ratio provide superior obesity and cardiovascular risk assessment compared to BMI and waist-to-hip ratio by directly measuring adiposity and regional distribution.
Use DXA to get your Fat Mass Index (FMI) and Android/Gynoid (AG) ratio. These are better predictors of cardiovascular risk and metabolic health than BMI or waist circumference alone. An AG ratio >1 indicates higher visceral fat risk.
GoodSupportsHIGH confidence
FMI has a clear advantage over BMI for the evaluation of obesity, as the latter does not take into account patients’ lean mass... increase in the android fat distribution (with values of AG ratio greater than 1) is associated with conditions such as dyslipidemia and insulin resistance

More from this paper
- Dual-energy X-ray absorptiometry (DXA) is the recommended clinical technique for assessing body composition (lean and fat mass) because it offers accuracy comparable to CT/MRI with significantly lower radiation exposure and cost.Good
- Sarcopenia diagnosis requires combining DXA-derived lean mass indices (specifically ASMMI) with functional strength tests; lean mass alone is insufficient for diagnosis.Good
