Results from the network meta-analyses confirmed these findings .
Conclusions Moderate- quality evidence from the present network meta- analysis suggests that D + E can be highly recommended for long-term obesity management .
Furthermore , the evidence suggests a moderate superiority of D over E with respect to anthropometric outcomes .
Background The aim of this meta- analysis was to compare the long-term efficacy of diet plus exercise ( D + E ) vs. diet ( D ) , D + E vs. exercise ( E ) and D vs. E on anthropometric outcomes and cardiovascular risk factors in overweight and obese participants .
Long-term (1- and 2-year) effects of lifestyle intervention in type 2 diabetes relatives.
AIMS To study the long-term ( 1- and 2-year ) effect of a lifestyle intervention on non-diabetic first-degree relatives of type 2 diabetic patients , i.e. , the 1-year effect of diet versus diet and exercise in relation to a control group and the 2-year sustainability of these treatment effects . METHOD Seventy-seven healthy first-degree relatives ( men and women ) between the ages of 25 and 55 were allocated to one of three groups : diet group ( D ) , diet and exercise group ( DE ) and control group ( C ) . For ethical reasons , after 1 year the control group began the intervention and were followed for another 2 years . Diet and physical activity counselling was based on current nutrition recommendations , including increased intake of fatty fish and low glycaemic index foods . The fatty acid composition of the erythrocyte membrane was studied as an objective measure of dietary change . Assessment s included fasting insulin , 2-h insulin , oral glucose tolerance test ( OGTT ) , anthropometry and blood lipid measurements . Groups D and DE received intensive follow-up through unannounced telephone interviews during the first 4 months . RESULTS Dietary changes were significant at 1 year , and to a large degree sustained at 2 years . Adherence to advice regarding fat quality was confirmed through changes in the fatty acid composition of the erythrocyte membrane . The least active subjects in DE increased their physical activity ( PA ) . At 1 year , group D showed a reduction in the ratio of LDL to HDL cholesterol ( p=0.028 ) while group DE decreased their body weight by 2.7 % ( p<0.029 ) and increased HDL ( p<0.037 ) versus controls . At 2 years , cholesterol levels ( total , LDL and the ratio LDL/HDL ) were reduced within group D and when compared to DE ( p=0.022 , 0.009 , 0.035 , respectively ) . Fasting insulin was reduced within group DE and when compared to group D ( p=0.025 ) . CONCLUSIONS Positive changes in lifestyle , blood lipids and fasting insulin can be achieved and maintained in a non-diabetic population at risk of type 2 diabetes after 2 years
