The results: 3 times greater fat loss in the HIIT group
Even though the energy cost of the exercise performed in the ET group was twice as high as the HIIT group, the sum of the skinfolds (which reflects subcutaneous body fat) in the HIIT group was three times lower than the ET group.
So where did the “9 times greater fat loss” claim come from?
Well, there was a difference in energy cost between groups, so in order to show a comparison of fat loss relative to energy cost, Tremblay wrote,
“It appeared reasonable to correct changes in subcutaneous fat for the total cost of training. This was performed by expressing changes in subcutaneous skinfolds per megajoule of energy expended in each program.”
Translation: The subjects did not lose 9 times more body fat, in absolute terms. But hey, 3 times more fat loss? You’ll gladly take that, right?
Well hold on, because there’s more.
