A 12-week study discussed in the interview found that adults combining an exercise and weight-loss program with creatine gained lean tissue while reducing body fat. Vanessa unpacks why that result is exciting, what "lean tissue" actually measures, and why the change in body fat percentage needs careful interpretation. In this episode: Why the quality of weight loss matters more than the number on the scale alone What the creatine study found about lean tissue and body fat during a weight-loss program Whether protein quality may matter more when calories are limited What a study comparing pork- and soy-based meals in military cadets found about recovery How much protein Dr. Gonzalez suggests as a practical starting goal for people who resistance train Why you don't need perfectly timed or evenly divided protein meals What firefighter research can—and cannot—tell us about time-restricted eating Where the evidence stands on creatine and cognition, probiotics, and other emerging supplements The central question: How can you lose body fat while giving yourself the best chance of maintaining—or even gaining—lean tissue?
