A significant positive effect of the interventions on weight was reported by all study types .
The meta- analysis showed that lifestyle interventions achieved weight and waist circumference reductions after one year .
However , no clear effects on biochemical or clinical parameters were observed , possibly due to short follow-up periods or lack of power of the studies meta-analysed .
Changes in dietary parameters or physical activity were generally not reported .
Most studies assessing feasibility were supportive of implementation of lifestyle interventions in routine clinical care .
Conclusion Lifestyle interventions for patients at high risk of diabetes , delivered by a variety of healthcare providers in routine clinical setting s , are feasible but appear to be of limited clinical benefit one year after intervention .
Despite convincing evidence from structured intensive trials , this systematic review showed that translation into routine practice has less effect on diabetes risk reduction
Background The clinical effectiveness of intensive lifestyle interventions in preventing or delaying diabetes in people at high risk has been established from r and omised trials of structured , intensive interventions conducted in several countries over the past two decades .
The challenge is to translate them into routine clinical setting s. The objective of this review is to determine whether lifestyle interventions delivered to high-risk adult patients in routine clinical care setting s are feasible and effective in achieving reductions in risk factors for diabetes .
Improvement of BMI, body composition, and body fat distribution with lifestyle modification in Japanese Americans with impaired glucose tolerance.
OBJECTIVE To determine whether diet and endurance exercise improved adiposity-related measurements in Japanese Americans with impaired glucose tolerance ( IGT ) . RESEARCH DESIGN AND METHODS This study compared the effects of an American Heart Association ( AHA ) step 2 diet ( < 30 % of total calories as fat , < 7 % saturated fat , 55 % carbohydrate , and < 200 mg cholesterol daily ) plus endurance exercise for 1 h three times a week ( treatment group ) with an AHA step 1 diet ( 30 % of total calories as fat , 10 % saturated fat , 50 % carbohydrate , and < 300 mg cholesterol ) plus stretching exercise three times a week ( control group ) on BMI , body composition ( % fat ) , and body fat distribution at 6 and 24 months of follow-up in 64 Japanese American men and women with IGT , 58 of whom completed the study . RESULTS At 6 months , the treatment group showed significantly greater reduction in percent , body fat ( -1.4 + /- 0.4 vs. -0.3 + /- 0.3 % ) ; BMI ( -1.1 + /- 0.2 vs. -0.4 + /- 0.1 kg/m(2 ) ) ; subcutaneous fat by computed tomography at the abdomen ( -29.3 + /- 4.2 vs. -5.7 + /- 5.9 cm(2 ) ) , thigh ( -13.2 + /- 3.6 vs. -3.6 + /- 3.0 cm(2 ) ) , and thorax ( -19.6 + /- 3.6 vs. -8.9 + /- 2.6 cm(2 ) ) ; and skinfold thickness at the bicep ( -2.0 + /- 0.6 vs. 1.1 + /- 0.6 mm ) and tricep ( -3.7 + /- 0.8 vs. -0.9 + /- 0.6 mm ) , which continued despite moving to home-based exercise for the last 18 months . CONCLUSIONS Diet and endurance exercise improved BMI , body composition , and body fat distribution and , thus , may delay or prevent type 2 diabetes in Japanese Americans with IGT
