D and PA+D  interventions had larger effects on glucose reduction  than PA alone .
Lifestyle  interventions significantly improved FPG , HbA1c , FI , HOMA-IR , and bodyweight among adults without IGT or diabetes , and might reduce progression of hyperglycemia to type 2 diabetes mellitus
This study systematic ally assessed the effectiveness of lifestyle interventions on glycemic indicators among adults ( ⩾18years ) without IGT or diabetes .
Supervised Exercise in Patients with Impaired Fasting Glucose: Impact on Exercise Capacity
Objective : To compare the effects of counseling alone with that of additional participation in supervised training courses on exercise capacity in patients with impaired fasting glucose . Design : R and omized , controlled intervention trial using a nested cohort approach . Setting : Primary care centers in western Austria . Patients : Thirty-six patients with impaired fasting glucose ( 16 males , 20 females ; mean age , 57.5 ± 6.9 years ) . Interventions : Participants of both groups were instructed about the preventive effectiveness of changing their lifestyle , especially losing weight and increasing physical activity . One group had additionally been offered supervised , progressive , individually tailored aerobic exercise programs for 1 hour twice a week . Main Outcome Measures : Changes in the levels of exercise capacity , body mass , and fasting blood glucose . Results : The subjects with supervised exercise participated in this program for 1.8 hours ( ± 0.3 ) per week over 12 months . Supervised exercise was sufficient to maintain exercise capacity , whereas counseling alone was not ( + 4.4 % versus -6.9 % ; P = 0.01 ) . After the 12-month intervention period , body mass was reduced in the supervised exercise group ( -3.0 % ) compared with the counseling alone group ( + 1.0 % ) ( P = 0.03 ) and fasting plasma glucose levels had similarly improved by counseling for adequate lifestyle changes alone ( -8.2 % ) and in combination with supervised exercise ( -6.0 % ) . Conclusion : In contrast to counseling alone , 2 sessions of supervised training per week , besides the self-chosen physical activity and nutritional measures , are sufficient to maintain exercise capacity in patients with impaired fasting glucose
