JJ Virgin explains prioritizing protein on each plate to support weight management, muscle maintenance, and healthy aging. She reviews how protein supports satiety, thermogenesis, and muscle repair; gives specific intake targets and body-fat ranges; provides practical meal examples (including animal- and plant-based options) and recommends pairing protein with non-starchy vegetables, healthy fats, and resistance training. The talk also covers age-related issues (sarcopenia, anabolic resistance), use of digestive enzymes, and tracking body composition.
