Damian Stoy was also a participant in the FASTER study (Jeff S. Volek, Daniel J. Freidenreich, Catherine Saenz, Laura J. Kunces, Brent C. Creighton, Jenna M. Bartley, Patrick M. Davitt, Colleen X. Munoz, Jeffrey M. Anderson, Carl M. Maresh, Elaine C. Lee, Mark D. Schuenke, Giselle Aerni, William J. Kraemer, Stephen D. Phinney. Metabolic characteristics of keto-adapted ultra-endurance runners. Metabolism, Volume 65, Issue 3, March 2016, Pages 100-110.).
put up his VO2max test results (UConn FASTER study and blood test results) and it is really interesting.
Damian is a male, 32 yrs old, 66″ tall vegan who weighs 128.6 lbs. Damian had a VO2max (of 63.4) which exceeded Ben Greenfield’s VO2max (61.1) (Rewriting The Fat Burning Textbook – Part 2: Why You’ve Been Lied To About Carbs And How To Turn Yourself Into A Fat Burning Machine.). I don’t see what the termination conditions were for either test. Damian’s VO2max had not flattened out as far a I can see and neither had Ben’s. In fact Damian’s RER of 1.21 is supposedly past the RER of 1.15 that I was told was a termination co-condition.
Ben did cross over the 1.0 RER number at 10:31 into the test and Damian crossed over at 8:02. It could be said that Ben is a great fat burner but it must also be admitted that Damian is a darned good carb burner.
They may have both dropped out due to RPE (Rate of Perceived Exertion). Again, there’s nothing here that account for what ended their test.
RER vs Ben Greenfield
What is fascinating is the RER numbers. The lowest RER value Damian ever got was 0.85 and it happened at a very early point in the test (26.5 or 43% of VO2max). That indicates to me that Damian is very adept at burning carbohydrates but not at all adapted to fat burning.
I wonder if his very low body weight affected the result? Now an “advantage” that Damian had was that he weighed quite a bit less than Ben Greenfield (128.6 lbs vs 173.9). The VO2max number is divided by body weight. Ben’s Max VO2 (not adjusted for weight) was 4.75 and Damian’s was 3.71 so Ben is using a lot more air volume but he’s larger so he has to.
Damian is also a professional runner (What is Wholistic Running?). Ben is an all-round athlete.
His Other Vegan Bloodwork
Damian posted his Fasting Glucose number and it was 94 which is in the reference range of 65-99 but somewhat high for an athlete. Not unexpected given his high carbohydrate diet.
His platelet count is also low at 137 (reference range 140-400).
