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 ClinicalTrials.gov, study id NCT01195610.

RESULTS: One hundred and ten participants (75%) completed the follow-up. Among participants previously randomised 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 randomised 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.
