Summary

Professor Phillips is a Tier 1 Canada Research Chair in Skeletal Muscle Health. In addition to being a full Professor in Kinesiology, also an Adjunct Professor in the School of Medicine at McMaster University. He is a fellow of the American College of Sports Medicine (ACSM) and the American College of Nutrition (ACN). His research is focused on the impact of nutrition and exercise on human skeletal muscle protein turnover. He is also keenly interested in diet- and exercise-induced changes in body composition.

His research is funded by the Canadian Institutes for Health Research, the National Science and Engineering Council of Canada, the Canadian Institutes for Health Research, and the Canadian Foundation for Innovation as well as the USDA.

He has received more than $2.4 million in research funding in the last 3 years. Dr. Phillips was the recipient of a New Investigator Award from the Canadian Institutes for Health Research and the Ontario Premier’s Research Excellence Award and in 2003 received the Canadian Society for Exercise Physiology Young Investigator Award. He currently has more than 18000 career citations, and 200 original scientific research and review papers.

In This Episode We Discuss

How good of a proxy for muscle growth is muscle protein synthesis?
Recommendations for daily and per-meal protein intake to maximize MPS
The influence of a calorie deficit on muscle protein balance: do you need more?
Whole eggs lead to greater MPS than egg whites: discussion of research paper
Anabolic resistance and strategies to overcome it

0:00.0	I think you can push it higher. I'm just not sure that that helps in retention of lean mass, to be honest with you.
0:21.6	And I'm not dismissing that, you know, you've got to put something into the machine
0:26.6	and I'm not just missing protein as a macronutrient in that situation.
0:31.6	But I think people need to appreciate them by far, and I mean by a long ways, the most potent anti-catabolic stimulus that you can provide yourself is obviously to perform resistance exercise. Hello and welcome to another episode of Sigma Nutrition Radio.
1:10.1	We're at episode 226 of the podcast today. And as ever,
1:15.5	I am your host, Danny Lennon. And I'm delighted today to be joined in a few moments by Professor
1:21.9	Stuart Phillips from McMaster University over in Canada, who has been at the forefront of research into
1:29.3	skeletal muscle health, particularly looking at interventions related to diet, particularly around
1:35.6	protein nutrition, as well as resistance training. And some of the implications for that on
1:41.2	hypertrophy, general muscle function, and then also muscle health and
1:46.4	function as we age, for example, in the cases of sarcopenia.
1:50.4	And he has been really a true leader in this area for many, many years.
1:55.6	And many of the world's top researchers in this field have came out of his lab as well or have spent time
2:01.9	under stew there too so really excited and privileged to have him on we're going to be digging into
2:08.0	all sorts of topics related to muscle protein balance looking at ideas like how good of a proxy
2:14.4	for muscle growth actually is muscle protein synthesis looking at some of the breakdown of recommendations given from recent research papers
2:22.7	came out of the McMaster Lab, as well as some other ideas about how a calorie deficit
2:27.3	might impact muscle protein balance and so on.
2:30.6	So really looking for today's show.
2:32.6	You're able to get the show notes over at sigmanutrition.com
2:36.7	slash episode 226. There I will link up to any of the research papers that we end up discussing
2:42.6	today in those show notes. And you can also get a transcript of today's podcast. And in fact,
	...
