Get 20% off at For nearly a decade, many of us have believed that calorie burn eventually plateaus—that once you move enough, your body quietly compensates and stops burning more energy.

But a brand-new 2025 human study challenges that idea in a way that could completely change how you approach fat loss, daily movement, and exercise. In this Friday recap episode of...

In today’s episode, Vanessa sits down with one of the most influential figures in obesity and metabolism research — Dr. James Hill, Professor of Nutrition Sciences at the University of Alabama at Birmingham and co-founder of the National Weight Control Registry. Dr. Hill has spent over four decades studying how people successfully lose weight, maintain it long-term, and preserve their lean mass and metabolic health.
Dr. Hill has led landmark clinical trials such as the Diabetes Prevention Program, Look AHEAD, and the Beef WISE Study on high-protein diets. His decades of work reveal why weight loss is only the beginning — and why the real secret to success lies in learning the completely different skill set of maintenance.

-
Three habits most long-term maintainers share (and one that surprised even him)
-
The moment your “diet” must flip into “maintenance”—and a simple sign you’re ready
-
The smallest daily tweak from his research that predicts whether you’ll regain or not
-
What exercise actually changes in your metabolism beyond calorie burn—and how much you really need
-
The simple resistance-training + protein formula he gives midlife women to keep muscle while losing fat
-
His three-bucket framework (diet, activity, mind state) and a 60-second self-check to find which bucket is breaking your results
-
The mindset shift that moves people from “I always regain” to “this is who I am” — plus a quick exercise to uncover your real why
-
The step-by-step exit plan he uses when patients come off GLP-1s—starting with what to do in week one to avoid rebound
If you’ve ever lost weight and struggled to keep it off, this episode shows you which levers matter most—and how to pull them so your results stick while your metabolism and muscle thrive.
