Podcast: In the Know with Nina
Episode with Dr. Lindsay Ogle
We talk with dietitian and health psychologist Nina Crowley about why body composition beats weight alone for understanding health, risk, and progress. We break down where BMI falls short, how modern bioimpedance works, and how to use the data without getting trapped by daily fluctuations.
• why weight and BMI miss muscle loss and hidden adiposity
• how body composition supports obesity treatment decisions and dosing pace
• why plateaus can still mean fat loss and muscle gain
• better goal setting that focuses on behaviors and fitness markers
• overview of body composition tests and what has improved over 20 years
• office-grade bioimpedance versus home scales and common accuracy pitfalls
• how often to measure so the numbers stay useful
• why a care team helps turn data into sustainable behavior change
