Mixed
High-intensity interval training (HIIT) has no significant effect on insulin, lipid profiles, C-reactive protein (CRP), or interleukin-6 (IL-6) in overweight/obese populations.
If you are overweight or obese, do not expect high-intensity interval training to significantly change your insulin levels, lipid profile, or inflammatory markers (CRP, IL-6). Focus on HIIT for its proven benefits on aerobic fitness, blood pressure, and body composition instead.
