The latest science on protein | Nicholas Burd, PhD

1 hour 51 minutes

Episode #310. For many of us looking to achieve athletic goals and age healthily, protein is something that is regularly front of mind. Join me as I sit down with Associate Professor Nicholas Burd, a muscle physiologist and researcher, to discuss the latest scientific evidence on protein. From selecting your protein source to choosing an appropriate amount for your goals, Dr Burd shares recent research findings on how to optimise your protein intake.

Discover the nuanced difference between optimising and maximising intake, the problem with eating too much protein, and why getting protein from whole foods is important. We also cover protein timing and distribution, supplementation, and much more.
