Description

Did you know there's a new way doctors may diagnose obesity? For decades, obesity has been defined simply by your BMI number, but leading experts are now proposing a more comprehensive approach that looks beyond just weight and height.

Join Holly and Jim as they welcome Dr. Eric Ravussin, a renowned physiologist from the Pennington Biomedical Research Center who has spent over 40 years studying human metabolism and weight regulation. They explore how this new obesity definition could transform treatment approaches, insurance coverage, and our understanding of weight-related health risks. You'll also hear about the groundbreaking research with Pima Indians that shows the interaction between genetics and environment in weight regulation.

Whether you're struggling with weight issues or simply interested in the science of metabolism, this episode offers insights into how medical professionals might soon approach obesity diagnosis in a more personalized and effective way.

Discussed on the episode:

• Why BMI alone isn't enough to diagnose obesity (and what metrics may replace it)
• The key difference between "preclinical" and "clinical" obesity in the new definition
• How this new classification system might affect insurance coverage and medication access
• The powerful interaction between genetics and the environment in the study of two Pima Indian populations
• Why your metabolism might matter more than previously thought (but not in the way you expect)
• The physiological importance of not eating all day long
• Dr. Ravussin's bold thoughts on what environmental changes might actually reduce obesity rates
