ABOUT PROFESSOR LUC VAN LOON:

Professor Luc van Loon is Professor of Physiology of Exercise at Maastricht University in the Netherlands. He is one of the world's leading researchers on muscle protein metabolism, with particular expertise in how nutrition and exercise affect muscle health across the lifespan.


14:15 - How much protein do we actually need?





I interviewed Professor Luc van Loon - one of the world's leading researchers on muscle protein metabolism at Maastricht University - to understand how much protein we really need, why muscle loss with age isn't inevitable, and practical strategies to get more from the protein you eat.



In this conversation, you'll learn:


* Why we lose 1-2% of our muscle daily (and how it completely renews every 50-100 days)

* The real reason older adults lose muscle - and why it's not inevitable

* How much protein you actually need per meal for optimal muscle building

* Plant vs animal protein: what the research actually shows

* Simple strategies to get more from the protein you eat





We often accept muscle loss as an inevitable part of aging, but is that truly the case? This video explores the science behind protein consumption and challenges the common idea of "muscle loss aging." With the rise of high protein diet products, it's important to understand how much protein do i need to build muscle and support overall longevity. We'll examine what the evidence says about protein's role, particularly in preventing age-related muscle loss.
