Kevin Hall, PhD On The Science & Politics of Weight Loss
Category: Education
Duration: 01:58:15
Publish Date: 2025-12-18 10:00:00
Description:

Kevin Hall, Ph.D., is a physicist-turned-nutrition scientist whose rigorous research has upended some of our most sacrosanct beliefs about metabolism, dieting, and weight loss.

This conversation explores why diets fail, the truth behind the "slow metabolism" myth, how ultra-processed foods hijack our biology, and why the 800-pound gorilla driving the obesity epidemic isn't willpower—it's our toxic food environment.

He also opens up about his decision to leave the NIH after 20 years due to political interference with his research.

Kevin is an honest actor, always trying to set matters to rights amidst a hurricane of nutritional misinformation. Enjoy!
