Fish Oil, Body-Fat Set Points, and Junk Volume

In this week’s episode, Eric presents a Research Review about the effects of fish oil on recovery and body composition, and answers a listener’s question about body-fat set points, settling points, and alternative models to explain weight regulation. In addition, Greg shares a brief research review about sports psychology, and answers listeners’ questions about training at long muscle lengths, micro-workouts, and junk volume. To close out the show, Eric revisits the topic of seed oil scaremongering.
