Some key points from the article...

"Interval-spawned weight loss, surprisingly, does not mostly come from the interval training itself (intervals use fast-burning glycogen, not slow-burning fat, as fuel), but from its long-known aftereffect: It ramps up the metabolism."

and

"Back in 1985, a study in the American Journal of Clinical Nutrition found that high-intensity training ramps up metabolism for 24 hours afterward, whereas low-intensity training does not. A 1991 study in the International Journal of Obesity found that more exercise intensity, not more duration, provoked increased post-exercise oxygen consumption. And a study published in December in the Journal of Applied Physiology and conducted by a team at Canada's University of Guelph found that just two weeks of alternate-day interval training increased moderately active 22-year-old women's fat-burning ability by 36%."
