Long-term adherence to the New Nordic Diet and the effects on body weight, anthropometry and blood pressure: a 12-month follow-up study
Abstract Purpose The New Nordic Diet ( NND ) has induced weight loss in a 26-week controlled intervention . We aim to investigate whether high compliance and satisfaction can be maintained after the active intervention is discontinued thereby maintaining the health effects . Methods After 26 weeks of intervention with NND or Average Danish Diet ( ADD ) , 147 participants ( mean age 43 years and mean BMI 29.1 kg/m2 ) were followed for further 52 weeks . All participants were encouraged to follow NND but without further guidance . The study is registered with Clinical Trials.gov , study i d NCT01195610 . Results One hundred and ten participants ( 75 % ) completed the follow-up . Among participants previously r and omised to NND ( NND group ) , dietary compliance and satisfaction decreased from 4.3 to 3.0 and from 4.8 to 4.0 , respectively ( both p < 0.0001 ) ( 1–5 point scale ) . Among those originally r and omised to ADD ( ADD group ) , satisfaction with NND was significantly higher than with ADD during follow-up ( 3.3 vs. 2.5 , p = 0.026 ) . Weight losses during intervention of −6.2 kg and −3.0 kg were followed by regains of 4.6 kg ( SE 0.5 ) and 1.1 kg ( SE 0.7 ) for the NND group and ADD group , respectively [ adjusted difference ; mean ( 95 % CI ) : 1.8 kg ( 0.1–3.4 ) , p = 0.041 ] . Across diet groups , every 1 score higher in compliance with NND was associated with 0.90 kg less body weight regain ( p = 0.026 ) and those who increased physical activity regained 3.4 kg less compared to those who did not ( p < 0.0001 ) . Conclusions NND  provides higher satisfaction , and body weight regain is reduced with higher compliance with NND and increased physical activity
Qualitative assessment of other anthropometric indices also showed a beneficial effect of this dietary pattern in improving body fat and BMI values ; however , these findings are not conclusive because of limited number of studies .
Adherence to the ND  significantly improves body weight ; however , there is also no certainty that this diet is effective for improving other anthropometric indices .
