Adherence
The effectiveness of interventions on fiber intake diminishes over time, with higher effects observed at 9-24 months compared to 36 months and beyond.
If you join a dietary program, expect the biggest benefits in the first two years. To maintain these benefits long-term, you need to connect the program's lessons to your daily life and ongoing support systems, as the structured intervention's effect fades after 3 years.
GoodQualifiesMEDIUM confidence
The subgroup analysis indicated that higher intervention effect in increasing fibre intake at 9–12 months (MD: 1·29; 95 % CI: 0·71, 1·88) and 18–24 months (MD: 2·08; 95 % CI: 0·81, 3·35) of follow-up compared with ≥ 36 months (MD: 0·08; 95 % CI: –0·52, 0·68), with statistically significant subgroup difference (P < 0·01).
