Bioelectrical Impedance Spectroscopy (BIS) is recommended as a feasible, noninvasive, and inexpensive method to assess body fat mass and visceral fat, explaining 80-90% of variance in fat mass compared to gold standards.
Bioelectrical Impedance Spectroscopy (BIS) is recommended for obesity trials as a feasible alternative to expensive imaging. It provides a good estimate of body fat and visceral fat, explaining up to 90% of the variance compared to gold-standard methods like DXA.
GoodSupportsHIGH confidence
It is recommended that all studies include more direct measures of FM by BIS... BIS has been reported to explain 80% to 90% of the variance in FM and visceral fat and 50% to 55% of the variance in intraabdominal fat by DXA and/or MRI.
Why this rating
Consensus guideline based on validation studies.

- Anthropometric measures (BMI, waist circumference, waist-to-hip ratio) are recommended as feasible, cost-effective core measures for obesity clinical trials, despite being less accurate than imaging methods like DXA or MRI.Good
- Calculated Resting Energy Expenditure (REE) using the Mifflin-St. Jeor equation is recommended over direct calorimetry for large clinical trials due to feasibility, though direct measurement is suggested if resources allow.Good
- Leptin, amylin, and adiponectin are recommended as core biomarkers for obesity trials to assess energy homeostasis and predict treatment response.Good
