As we age, our bodies undergo numerous changes, including a decline in muscle mass and cognitive function. For many of us, exercise and diet play crucial roles in maintaining our health and well-being.

But how can the protein we eat affect our abilities to exercise and stay healthy as we age?

It can be difficult to separate fact from fiction when it comes to the effects of protein. How much do we need? Is it better to eat protein before or after exercise? And what roles do protein and exercise play in brain function?

In today’s episode, Jonathan is joined by Prof. Ben Wall, an expert in nutritional physiology at the University of Exeter. Together, they unpack the latest scientific research on the connection between protein consumption and exercise.

Prof. Ben Wall shares his insights into the optimal amount and timing of protein intake for building and maintaining muscle mass, as well as the potential impact of exercise on cognitive function and brain health into later life.
