Evolving perspectives on evaluating obesity: from traditional methods to cutting-edge techniques

Area of Science:

• Medical Science
• Metabolic Health
• Diagnostic Technologies

Background:

• Obesity evaluation has traditionally relied on anthropometric indices like Body Mass Index (BMI).
• Visceral adipose tissue (VAT) plays a critical role in metabolic diseases.
• Limitations exist in traditional methods for assessing visceral adiposity and associated risks.

Purpose of the Study:

• To review the evolution of obesity evaluation methods.
• To compare the clinical utility and limitations of various assessment techniques.
• To explore personalized assessment of visceral adiposity and metabolic risks.

Main Methods:

• Literature review of anthropometric indices (BMI, WC, WHR, WHtR, NC).
• Analysis of lipid-related metrics (LAP, VAI, CVAI, mBMI).
• Evaluation of imaging technologies (3D scanning, BIA, ultrasound, DXA, CT, MRI) and adipocyte biology.

Main Results:

• Anthropometric measurements are still guideline-based but have limitations.
• Lipid metabolism indicators offer more accurate reflection of visceral obesity and metabolic disease links.
• Advanced imaging (ultrasound, CT) provides intuitive assessment of visceral obesity extent.

Conclusions:

• Lipid-based indicators and advanced imaging surpass traditional methods for visceral obesity assessment.
• Personalized assessment of metabolic risks associated with visceral adiposity is enhanced by newer techniques.
• The evolution of obesity evaluation methods supports more precise clinical decision-making.
