Study under review: Whey Protein Supplementation Preserves Postprandial Myofibrillar Protein Synthesis during Short-Term Energy Restriction in Overweight and Obese Adults
Stuart Phillips’ group at McMaster University has been conducting research on all things protein for close to two decades, with particular emphasis on how protein feeding affects protein synthesis at the whole-body level, as well as specifically in the muscle tissue (obtained from muscle biopsy specimens).
Measuring protein synthesis (or degradation) in muscle is the best biomarker of ongoing muscle anabolism or catabolism that exists. Protein synthesis during weight loss is important since keeping muscle on helps regulate blood sugar and keeps metabolism higher. Obtaining information about fat or protein turnover at a particular point in time can tell us how well the body is conserving lean mass during weight loss, which is what this study intended to do.
