Low-carb endurance athletics seems to be getting more traction, which is strange. Alan Aragon undercuts Dr. Volek's attempt to assemble evidence: >Pre and post-keto-adaptation endurance capacity (measured by time to exhaustion or TTE) was not significantly different. This lead the authors to conclude that aerobic endurance at 62-64% of VO2max was not compromised by the 4-week ketogenic diet phase. Mean TTE in the non-keto and keto conditions were 147 and 151 minutes, respectively. However, the authors’ conclusion is misleading since 2 of the 5 subjects experienced substantial drops in endurance capacity (48 & 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 & 30 minutes.
