Interesting, but I'm not sure what I'm looking at. Was this a direct measurement of substrate utilization? I don't see data points on the graph so I wouldn't think so. It could be they measured gas exchange and then applied a model to correlate gas exchange to fat/CHO, but again no data points. Finally, did they simply apply a model to an assumed or measured threshold? That would be consistent with the smooth curve with no data points. If a model was involved, it raises the question of how accurate and accepted it is. The fact that whoever created this plot was sloppy with their axis labels doesn't help with their credibility. A reference would help.
