HIIT is more time-efficient than MICT for achieving similar fat loss outcomes, primarily due to excess post-exercise oxygen consumption (EPOC) and appetite regulation.
If you are short on time, HIIT can provide similar fat loss benefits to longer cardio sessions in less time, thanks to increased calorie burn after exercise.
ModerateSupportsMEDIUM confidence
HIIT was 39% more time-efficient than MICT (HIIT: 22 min; MICT: 36 min), which is explained by excess postexercise oxygen consumption and appetite regulation.
Why this rating
Based on a single study within the review (Aristizabal et al.), not a pooled meta-analysis result.
