The Dr. Gabrielle Lyon Show

In this episode of The Dr. Gabrielle Lyon Show, I sit down with Dr. Layne Norton, a scientist and nutrition expert, to unpack the complex truths behind obesity, weight management, and diet myths. Together, we discuss what truly drives weight gain beyond the “calories in vs. calories out” model, exploring the impacts of hormones, metabolic rates, and lifestyle choices.

We dive into:

- How the body processes carbs, fats, and proteins

- Challenging the carb-insulin model of obesity

- Practical tips on meal structuring and muscle maintenance

- The significance of personalized diets and resistance training

If you’ve ever been curious about low-carb vs. high-carb diets, calorie counting, or how exercise impacts weight, this episode breaks it all down with science-backed detail. Don’t miss this eye-opening conversation packed with actionable advice for achieving sustainable, healthy weight loss and building lifelong fitness.
