Today's episode of the PSMF series is a special conversation from the archives with bestselling author and nutrition expert Maria Emmerich. We explore how a protein-sparing modified fast can be used strategically to accelerate fat loss while prioritizing protein and protecting precious lean muscle.

Maria explains the important difference between losing weight and losing body fat—and why simply adding more dietary fat may work against your goals when fat loss is the priority. We discuss how PSMF differs from traditional keto, fat fasts, egg fasts, intermittent fasting and extended fasting, as well as why protein should remain at the center of a body-recomposition plan.

Maria also shares practical strategies for overcoming sugar cravings, creating a supportive food environment and making satisfying high-protein meals easier. We talk about common obstacles such as relying on packaged "keto" foods, drinking high-fat coffees, overeating dairy and nuts, underestimating dietary fat and trying to obtain an entire day's protein in one meal.
