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 .
Effect of lifestyle changes on erectile dysfunction in obese men: a randomized controlled trial.
CONTEXT Healthy lifestyle factors are associated with maintenance of  erectile function in men . OBJECTIVE To determine the effect of weight loss and increased physical activity on erectile and endothelial functions in obese men . DESIGN , SETTING , AND PATIENTS R and omized , single-blind trial of 110 obese men ( body mass index > or = 30 ) aged 35 to 55 years , without diabetes , hypertension , or hyperlipidemia , who had erectile dysfunction that was determined by having a score of 21 or less on the International Index of Erectile Function ( IIEF ) . The study was conducted from October 2000 to October 2003 at a university hospital in Italy . INTERVENTIONS The 55 men r and omly assigned to the intervention group received detailed advice about how to achieve a loss of 10 % or more in their total body weight by reducing caloric intake and increasing their level of physical activity .  Men in the control group ( n = 55 ) were given general information about healthy food choices and exercise . MAIN OUTCOMES MEASURES Erectile function score , levels of cholesterol and triglycerides , circulating levels of interleukin 6 , interleukin 8 , and C-reactive protein , and endothelial function as assessed by vascular responses to l-arginine . RESULTS After 2 years , body mass index decreased more in the intervention group ( from a mean [ SD ] of 36.9 [ 2.5 ] to 31.2 [ 2.1 ] ) than in the control group ( from 36.4 [ 2.3 ] to 35.7 [ 2.5 ] ) ( P<.001 ) , as did serum concentrations of interleukin 6 ( P = .03 ) , and C-reactive protein ( P = .02 ) . The mean ( SD ) level of physical activity increased more in the intervention group ( from 48 [ 10 ] to 195 [ 36 ] min/wk ; P<.001 ) than in the control group ( from 51 [ 9 ] to 84 [ 28 ] min/wk ; P<.001 ) . The mean ( SD ) IIEF score improved in the intervention group ( from 13.9 [ 4.0 ] to 17 [ 5 ] ; P<.001 ) , but remained stable in the control group ( from 13.5 [ 4.0 ] to 13.6 [ 4.1 ] ; P = .89 ) . Seventeen men in the intervention group and 3 in the control group ( P = .001 ) reported an IIEF score of 22 or higher . In multivariate analyses , changes in body mass index ( P = .02 ) ,  physical activity ( P = .02 ) , and C-reactive protein ( P = .03 ) were independently associated with changes in IIEF score . CONCLUSION Lifestyle changes are associated with improvement in sexual function in about one third of obese men with erectile dysfunction at baseline
