My guest today is Stuart Phillips, Ph.D. He obtained his Ph.D.
from the University of Waterloo in Human Physiology. He joined
McMaster University in 1999 as an Assistant Professor and is
currently a full Professor in the Department of Kinesiology and
Medicine. He is also the inaugural Director of the McMaster Centre
for Nutrition, Exercise, and Health Research. His research is
focused on the impact of nutrition and exercise on human protein
turnover, specifically in muscle. He is also interested in how
exercise and protein impact body composition, strength, and
function in aging. His research is funded by the Canadian
Institutes for Health Research, the National Science and
Engineering Council of Canada, the US Department of Agriculture,
and the Canadian Foundation for Innovation. He has authored more
than 190 research papers and several newspaper and magazine
In this episode, we learn:
- What are the overall (daily) protein needs of endurance
athletes, and will this differ for ultra marathon runners?
- Does it matter if we get it throughout the day vs mostly at one
or two meals?
- Does our daily average need to be daily or can it average over
- Is there a protein hunger, per se, that is reliable and will we
self regulate sufficiently?
- What is protein used for in an endurance athlete? How much
protein is used for energy /ATP?
- What do we know, or can we expect about protein needs and use
during and following an ultra?
- Is protein immediately before, during, or immediately after
training handled differently?
- Is it beneficial to consume protein immediately after a
- Are there adverse effects of excess protein?
- Are all proteins equal?
And, as always, we what up with an advice
- What advice might he give to an ultra marathon runner concerned
with their protein intake?
