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 .
VLCD versus LCD in long-term treatment of obesity
OBJECTIVE : To compare the long-term effects of three different programs including initial 6 weeks (V)LCD diets 420 kcal/d , 530 kcal/d , 880 kcal/d ) on sustained weight loss , attrition and obesity associated conventional cardio-vascular risk factors . DESIGN : Prospect i ve , r and omized clinical 52 weeks trial . Two weeks of a booster (V)LCD period after week 26 . SETTING : University outpatient obesity clinic . SUBJECTS : Ninety-three middle-aged obese patients ( 30 men ) , initial mean BMI 38.7 kg/m2 , age 20–65 y , from the waiting list . MAIN OUTCOME MEASURES : Weight loss pattern , attrition , reported side effects , blood pressure , blood glucose and serum lipid levels . Repeated frequent measurements up to week 26 , intermittently up to final measurements at week 52 . RESULTS : One year attrition ( 30–45 % ) , sustained weight loss ( 8–15 % of initial body weight ) and changes in obesity associated risk parameters were similar in all three group . Fewer adverse events were reported in the LCD group . CONCLUSION : The results compare favorably with most previous reports of similar design . VLCD ( 420 kcal or 530 kcal/d and LCD 880 kcal/d ) were equally effective in long term treatment of obesity . The tendency to less side effects with LCD suggests that such preparations deserve further attention
