Obesity is a ‘complex’ problem that goes beyond BMI, experts say

Obesity is a complex issue that affects millions of people worldwide. It is not simply a matter of excess weight, but rather a systemic metabolic disorder that requires individualized care. A group of 58 researchers recently published their recommendations for a new way to measure obesity in The Lancet Diabetes & Endocrinology.

For decades, Body Mass Index (BMI) has been the international standard for measuring obesity. However, experts have questioned its validity as a sole measure of obesity. BMI is calculated by dividing a person’s weight by the square of their height in feet.

Lead author of the report, Francesco Rubino, emphasized that obesity is a spectrum rather than a distinct clinical entity. The researchers propose a new framework that distinguishes between preclinical and clinical obesity. Preclinical obesity refers to individuals with excess body fat that has not yet affected their tissues and organs. On the other hand, clinical obesity is characterized by chronic illness and organ dysfunction due to excess adiposity.

To accurately assess obesity, the researchers recommend measuring adiposity through waist circumference or body scans to determine fat mass. This new approach aims to provide a more comprehensive understanding of obesity and its impact on overall health.

Dr. Brett Osborn, a neurosurgeon and longevity expert, supports the shift away from BMI as the sole measure of obesity. He emphasizes the importance of considering factors like inflammation, insulin resistance, and glucose tolerance in diagnosing obesity. In his clinic, Dr. Osborn focuses on metrics such as visceral fat scores, skeletal muscle mass, and body fat percentage to provide personalized care for his patients.

By integrating body composition metrics and metabolic markers, healthcare professionals can more accurately diagnose obesity and tailor interventions to individual needs. This new approach offers a more nuanced understanding of obesity as a metabolic disorder, rather than simply a matter of excess weight.

In conclusion, the recommendations put forth by the group of researchers offer a new perspective on measuring obesity and provide a foundation for personalized care and interventions. By moving away from outdated measures like BMI and focusing on a holistic view of obesity, healthcare providers can better support individuals in managing their health and well-being.
