In this episode, Vanessa breaks down a groundbreaking new study published in Nature Metabolism (June 2025), revealing what actually happens when you double your protein intake. The results? Participants naturally ate 196 fewer calories per day, burned an additional 128 calories per day, and stored fewer calories as fat — all without trying to eat less. Vanessa unpacks how these findings support the protein leverage hypothesis, how they apply to real-life fat loss and body recomposition for women, and why increasing protein may be the missing link for anyone stuck in a weight loss plateau. You’ll learn how doubling protein affects hunger hormones, metabolism, and nutrient partitioning — plus get Vanessa’s own experience applying these principles for effortless appetite control and improved body composition.
