How does the paper you posted, about post exercise oxygen consumption, relate to weight loss as we have been discussing here? I don't mean this to be flippant, I just don't have time to do a deep dive on this paper and you didn't provide any context.

  Reading the abstract is always a good start! ;PPPP "A number of investigators in the first half of the last century reported prolonged EPOC durations and that the EPOC was a major component of the thermic effect of activity. It was therefore thought that the EPOC was a major contributor to total daily energy expenditure and hence the maintenance of body mass. Investigations conducted over the last two or three decades have improved the experimental protocols used in the pioneering studies and therefore have more accurately characterized the EPOC. Evidence has accumulated to suggest an exponential relationship between exercise intensity and the magnitude of the EPOC for specific exercise durations. ... Notwithstanding the aforementioned, the earlier research optimism regarding an important role for the EPOC in weight loss is generally unfounded. This is further reinforced by acknowledging that the exercise stimuli required to promote a prolonged EPOC are unlikely to be tolerated by non-athletic individuals. The role of exercise in the maintenance of body mass is therefore predominantly mediated via the cumulative effect of the energy expenditure during the actual exercise."

Here's a experiment from 2011, five years after that paper (in fact it cites it), N=22 and using a metabolic chamber: "A 45-Minute Vigorous Exercise Bout Increases Metabolic Rate for 14 Hours" https://www.academia.edu/download/45878998/A_45-Minute_Vigorous_Exercise_Bout_Incre20160523-5557-bxx62y.pdf https://www.academia.edu/download/45878998/A_45-Minute_Vigor... where they conclude ".. vigorous exercise for 45 min resulted in a significant elevation in postexercise energy expenditure that persisted for 14 h. The 190 kcal expended after exercise above resting levels represented an additional 37% to the net energy expended during the 45-min cycling bout"
