Today we are speaking with Dr. Bill Campbell, whose work I've followed for a few years, including his monthly research review Body by Science. We are tackling five very important topics related to improving your body composition to get the physique you want, including how consuming highly processed foods impacts your goals, the effectiveness of a rapid fat loss phase, why weight plateaus occur, and how to break them, physique-training vs. nutrition, and the use of diet breaks and refeeds to optimize your physique.

Bill Campbell is a Professor and Director of the Performance & Physique Enhancement Laboratory at the University of South Florida. He publishes a monthly research review (Body by Science) that summarizes the latest and best research focusing on fat loss and building muscle.

Bill has published over 200 papers, 3 textbooks, and 20 book chapters related to physique enhancement, and his articles have been cited over 7,000 times.

He also is the co-creator (with Dr. Layne Norton) of the "Physique Coaching Academy" - the most comprehensive and evidence-based course and mentorship program helping weight loss and physique coaches across the world.
