Dr. Nick Burd, PhD, is a skeletal muscle physiologist with an expertise in protein metabolism and exercise. In this episode, Dr. Burd discusses the importance of maintaining muscle mass as we age, expressing that “strong is the new healthy.” 

While adequate protein intake is an important aspect of gaining muscle and maintaining healthspan, many people in the US actually over consume protein. In this discussion, Dr. Burd talks about how much protein we truly need, whether or not there is an optimal time to consume protein after exercise, and how to best distribute protein intake throughout the day. He explains why consuming protein from food sources rather than as a powder may be better for muscle growth, and shares why protein is critical for endurance athletes. Episode timestamps:
