”Third, endurance athletes exercising at >85%VO2max, whilst performing 6 × 800 m running intervals, measured the highest rates of fat oxidation yet reported in humans. Peak fat oxidation rates measured at 86.4 ± 6.2%VO2max were 1.58 ± 0.33 g/min with 30% of subjects achieving >1.85 g/min.”

well, I guess you can call them whenever you want… BUT… athletes that had been on ketogenic diet for a month have been showing to have a crossover point at 85% of VO2 max and fat anabolism rate of 1.6 g per minute.

I sent you a link to an actual study that demonstrates that and I could send more similar ones… Where does the information come from, for your chart? Do you know how they we eating off the bike. Clearly, from link I posted, what you eat off the bike has a pronounced and significant affect on fat metabolism on the bike!
