A long, long time ago...
I learned that Everyone is Different, thanks to a study by Julia H. Goedecke, Alan St Clair Gibson, Liesl Grobler, Malcolm Collins, Timothy D. Noakes and Estelle V. Lambert.
Well, stone the flamin' crows! Timothy D. Noakes' name just popped up in Alan Aragon's article 2013 NSCA Personal Trainers Conference: Looking Back at my Debate with Dr. Jeff Volek. Dr. Noakes has had problems with his blood glucose level and has adopted a very-low-carb/ketogenic diet.
What also caught my eye in Alan Aragon's article was (Note: TTE = Time To Exhaustion):-
"However, the authors’ conclusion is misleading since 2 of the 5 subjects experienced substantial drops in endurance capacity (48 and 51-minute declines in TTE, to be exact). One of the subjects had a freakishly high 84-minute increase in TTE, while the other increases were 3 and 30 minutes."
I expect that the subjects with 84 and 30 minute increases in TTE would be praising ketogenic diets, whereas the subjects with 48 and 51 minute
declines in TTE would be cursing them and the subject with 3 minutes increase would be "Meh". Vive la difference!
Also note that sprint capability...remained constrained during the period of carbohydrate restriction. As mentioned in It's all in a day's work (as measured in Joules), exercise above a certain intensity (~85%VO2max) burns significant amounts of carbs, no matter how fat-adapted someone is.
