MASS Office Hours Episode 30 (Pros and Cons of Refeeds + Q&A)

In this episode of MASS Office Hours, Dr. Eric Trexler and Dr. Eric Helms dive into the psychology of refeeds in bodybuilding, discussing a recent study that found relationships between intuitive eating skills, emotional coping ability, and controlled calorie intake during refeed meals. They also touch on the evolving research on physiological benefits of refeeds and diet breaks, and the importance of individualization in approach. Listener questions are addressed, including the viability of using refeeds while staying lean year-round, the utility of "fat loss sprints," thoughts on measuring cortisol, and the trustworthiness of GMP certification for supplements. The episode concludes with a discussion on the differences and similarities between competitive bodybuilding, recreational/"Instagram" bodybuilding, and general fat loss, with Helms noting key distinctions in process and end goals, but emphasizing that anyone can claim the bodybuilder title. The MASS crew goes live for Office Hours every Wednesday night at 7pm eastern time. Be sure to join us for a future episode!
