Three Key Strategies to Lose Fat and Keep Muscle

In this episode of the Optimal Protein Podcast, Vanessa sits down with sports nutrition scientist Dr. Jose Antonio, one of the world's leading researchers on protein metabolism and body composition.

Dr. Antonio is widely known for his groundbreaking protein overfeeding studies, which found that participants consuming extremely high protein diets did not gain body fat — and in some cases actually lost more fat — even while eating more calories.

In this conversation, Vanessa and Dr. Antonio explore the fascinating metabolic reasons why protein behaves differently in the body, including its thermic effect, impact on satiety, and role in preserving lean mass during fat loss.

They also discuss the newly evolving protein recommendations, how protein interacts with carbohydrates and fats in the diet, and why certain athletes may benefit from lower carbohydrate approaches depending on their sport and metabolic demands.

If your goal is fat loss, body recomposition, or maintaining muscle while dieting, this episode offers a deep dive into the science behind why prioritizing protein can be such a powerful strategy.
