The MASScast Iron Culture episodes are back! Today Dr. Eric Trexler joins us to answer the murky question: “What is an evidence-based guideline for a minimum dietary fat intake?” It’s easy to find guidelines and minimums for various circumstances and goals for protein, and while there is some debate, the same could be said for carbohydrate. However, a minimum intake for fat has been elusive. Fortunately, Dr. Trexler has been thinking deeply about this topic and wrote an extensive article on the topic in our upcoming issue of The MASS Research Review, and he’s here to discuss his conclusions in depth with the CULT. Make sure to tune in, as this information can inform best practices in various situations, as the answer isn’t a simple black and white one.
