I'm doing HIIT for VO2 improvement and wondering if that'll help with fat loss as well.

I've read a lot of conflicting reports, including one fellow who said "there a study on this that will be published soon" (but no date on th article (arrggg!).


Found this research

Which compared Endurance Training vs. HIIT showing that relative to the energy expended, HIIT was 9x as effective in reducing fat.

(This isn't exactly the comparison I was looking for but it's a good start)

But this other study contradicts that

This study suggests that fat loss is a function of energy expended rather than exercise intensity.

  • I think making it relative to energy use is skewing the results. Most HIIT I know, e.g. tabata, use a lot less energy than an endurance workout. I'm also skeptical of that result, as I've read more that says lower intensity is better for burning fat. – andrewb Nov 27 '13 at 7:05
