ntroduction: Interleukin-6(IL-6) and Tumor Necroes Factor-alpha (TNF-α) are secreted by adipose tissue and are potential regulators of low grade inflammation and metabolic disorders in Obesity Type 2 Diabetes (OT2D). hence, present study examined the effects of interval training with different diet on low grade inflammation and some of metabolic indexes in OT2D.
 Methods: forty-five  OT2D men were randomly assigned into a High intensity interval training(HIIT) plus  normal diet group (ND+H), low carbohydrate diet plus   HIIT group(LC+H)   or  HIIT plus   low fat diet group(LF+H) that involved adherence to a 1200-1500 kcal/day(ND+H: 28% fat, 54% carb and 18% protein; LC+H: 42% fat, 40% carb and 18% protein; LF+H: 20% fat, 62% carb and 18% protein) while participating in a supervised HIIT (3 d/week for 12 weeks). Anthropometrics, physiologic features and fasting blood samples were obtained at 0, 8(8 weeks diet only), 16, 20(12 weeks HIIT plus diet) and 24(4 weeks diet only) weeks.
Results: Maximum Oxygen Consumption (VO2max) after 24 weeks of intervention, the LC + H group (P = 0.001, F = 2.195) and LF + H group (P = 0.014, F = 3.548) showed a significant decrease Compared to the pre-test, this decrease was not observed in the ND + H group. The decrease in IL-6 index with other variables (except for maximum oxygen consumption) showed a significant relationship, but the VO2max index had a significant reverse relationship [for LC + H group (p = 0.001, r = -0.54); For LF + H group (p = 0.019, r = -0.41 =), they showed IL-6. In line with changes in IL6, there was a significant difference in TNF-α index in all stages of the study. After 24 weeks of intervention, the LC + H group (P = 0.001, F = 5.541) and LF + H group (p = 0.001, F = 9.654) had a significant reduction compared to the pre-test , But this decrease was not observed in the ND + H group. Significant increase in VO2peak with significant decreases in insulin, HOMA-IR and HbA1c was observed in all groups. Also, there was a significant decrease in IL-6 and TNF-α in LC + H and LF + H groups. Changes in IL-6 and TNF-α showed an inverse association with peak oxygen consumption. Pearson's analysis revealed meaningful relationships between changes in lipid profiles with peak oxygen consumption. VO2peak significant increases in all groups with significant decreases in insulin, HOMA-IR and HbA1c in all groups. Also, IL-6 and TNFα significant decreases in LC+H and LF+H groups. Changes in IL-6 and TNFα significantly Inverse correlated with VO2peak.  Pearson analysis revealed significant correlations between changes in lipid profile to VO2peak.
Conclusion: Results support contentions that diet and exercise affects low grade inflammatory and fitness, lipid and glycemic profiles that changes in IL-6 and TNF-α be correlated with some of these changes.
