Dr Campbell's Instagram In this episode we cover: Bill's love for bodybuilding and how it lead to him pursuing a career in the the science of physique change. Bill's laboratory, the Physique Lab and their focus on exercise performance and physique science, resistance exercise and diet. Bill's philosophy around the importance of making fat loss protocols sustainable. The work of the International Society of Sports Nutrition and the importance of the ISSN position stands for people wanting to learn more about sports nutrition. The important difference between weight loss and fat loss Why approaches to weight loss may be different for someone with obesity and those trying to lose weight for a physique competition. The very novel competition Dr Campbell ran for his Masters students, to get them to design a rapid fat loss protocol. The issues associated with "rapid" fat" fat-loss techniques and how diet-breaks can help alleviate some of those problems Can diet-breaks help maintain muscle mass and metabolic rate as well as improving overall fat-loss? What specific diet-break strategies has Bill looked at in his research? Why using diet breaks might make weight loss more realistic in a real life scenario. Why do women make much better research subjects than men? Can dieting aggressively at the start of the diet be better than a longer but less strict diet? The difference between intent-to-treat and per-protocol analysis in research and why it matters to diet research The All-Star panel of judges Bill had judging his students fat-loss protocols What areas of physique science does Bill want to delve into in the future: what's so special about high protein diets?
