HIIT improves glycaemic control (HbA1c, 2h glucose) and reduces visceral fat in type 2 diabetes, but does not significantly change fasting glucose or insulin sensitivity (HOMA-IR) within the study period.
HIIT helps lower your average blood sugar (HbA1c) and improves how your body handles sugar after meals, even if your fasting blood sugar doesn't change immediately. It also reduces visceral fat. Stick to the 12-week protocol; the benefits on liver fat and overall glucose control are significant, even if fasting numbers remain stable.
HIIT had no impact on fasting glucose... or fasting insulin... however, between-group comparisons revealed improvements in HbA1c, 2 h glucose and AUGC... There was no improvement in insulin sensitivity (HOMA2 of insulin resistance [HOMA2-IR] and HOMA2 of insulin sensitivity [HOMA2-%S])
Why this rating
RCT design, but small sample size and high inter-individual variation in liver fat response.
