Fish Oil, Body-Fat Set Points, and Junk Volume (Episode 76)



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.

  1. As a MD, I never think of fish oil or epa/dha as health supplements , since the effect is so minimal and mainly studied on young people whos risk of dying is incredible low.

    However, they can cause problems with blood clotting, so people with diabetes, cancers, significant atherosclerosis, family history of clots or bleeds etc. should avoid them. Bear in mind that these diseases/disorswrs are commonly undiagnosed for months, years or even decades. The significance of the effect is debated, but there is some pretty decent evidence for it.

    Also, in population scale, I have never met a patient with health problems due to inadequate epa/dha intake. It just dont believe this is the thing to consider in your nutrition. Its just an afterthought of an afterthought

    I still struggle to see the benefit for strength or hypertrophy. Are we really saying an athlete is significantly better after 10 years of training and fish oil supplementation than without the fishoil (since this is the primary outcome we want)?

  2. The Nutrivore? What a joke, ask him why he won’t debate Bart Kay on these topics. Humans are obligate carnivores and can handle some plant matter at times of famine or starvation but that will lead to negative health outcomes.

  3. As a natural, I can easily be about 240lbs with around 12-16% body fat. I'm 6'1''. So am I just too jacked? Is it genetics? Is it my iron willpower to lift weights both gracefully, forcefully, and with precision?

  4. If you're just going with what's in the comments, I'd enjoy a weekly 6 hour podcast. I'll go ahead and assume that's happening for next week.

  5. there is a guy on reddit with a 500lb bench who does what the bicep person was asking. they work from home and i think every hour or two they would just go in and hit a set of bench and then go back to work. so some times during they day they would hit ten sets spread out 14 hours.

  6. man, this idea of sets per workout is a tough one…i, personally, at 51 years old, with three years training, feel that 6-8 sets to "failure" just isnt enough psychologically—i just dont feel satisfied….but what is failure? and what does hard work mean to each person?…i raced bicycles for 22 years—the training was grueling, the races inhumanly difficult, so for me workouts in the gym just seem so easy—so i guess its sorta relative from a psychological standpoint
