Stretch-Mediated Hypertrophy and Reverse Dieting (Ep 96)

We’re officially back for a brand new season! In today’s episode, Greg discusses the research behind how resistance training range of motion impacts muscle growth, with a special focus on stretch-mediated hypertrophy. After that, Eric dives deep into the topic of reverse dieting, which is often touted as a remedy for metabolic adaptation and a strategy to facilitate easier and more sustainable weight loss. However, this popular approach was originally driven by industry marketing rather than scientific evidence. Eric’s segment explores the actual research related to reverse dieting, which tells a much different story than the hyped-up anecdotes you’ll see on social media. He also explains why reverse dieting often appears to work in the short term while falling flat in the long term, and why a simple maintenance phase is a better option than reverse dieting.
