Abstract
OBJECTIVE We aimed to examine the effects of a 5:2 regimens diet (2 days per week of energy restriction by formula diet) or an exercise (2 days per week of high-intensity interval training and resistance training) intervention compared with routine lifestyle education (control) on glycemic control and cardiometabolic health among adults with overweight/obesity and type 2 diabetes. RESEARCH DESIGN AND METHODS This two-center, open-label, three-arm, parallel-group, randomized controlled trial recruited 326 participants with overweight/obesity and type 2 diabetes and randomized them into 12 weeks of diet intervention (n = 109), exercise intervention (n = 108), or lifestyle education (control) (n = 109). The primary outcome was the change of glycemic control measured as glycated hemoglobin (HbA1c) between the diet or exercise intervention groups and the control group after the 12-week intervention. RESULTS The diet intervention significantly reduced HbA1c level (%) after the 12-week intervention (−0.72, 95% CI −0.95 to −0.48) compared with the control group (−0.37, 95% CI −0.60 to −0.15) (diet vs. control −0.34, 95% CI −0.58 to −0.11, P = 0.007). The reduction in HbA1c level in the exercise intervention group (−0.46, 95% CI −0.70 to −0.23) did not significantly differ from the control group (exercise vs. control −0.09, 95% CI −0.32 to 0.15, P = 0.47). The exercise intervention group was superior in maintaining lean body mass. Both diet and exercise interventions induced improvements in adiposity and hepatic steatosis. CONCLUSIONS These findings suggest that the medically supervised 5:2 energy-restricted diet could provide an alternative strategy for improving glycemic control and that the exercise regimen could improve body composition, although it inadequately improved glycemic control.
