Adherence
An internet-based health intervention (Guide to Health) significantly increases fruit and vegetable servings and fiber intake in adults compared to a waitlist control, with effects sustained at 16-month follow-up.
To improve your fruit and vegetable intake and fiber, use a structured online program that guides you through weekly goals. The key is consistency: complete one module per week, set a specific strategy (like taking fruit to work), and track your progress. If possible, join a group or community setting (like a church or workplace) that reinforces these goals with visual reminders and shared targets, as this significantly boosts adherence and long-term results.
Participants in GTH-Only increased F&V at post ((cid:2)1.50 servings) compared to control ((cid:2)0.50 servings; p ¼ .005) and at follow-up ((cid:2)1.20 vs. (cid:2)0.50 servings; p ¼ .038) and increased fiber at post ((cid:2)3.00 g) compared to control ((cid:2)1.5 g; p ¼ .006) and follow-up ((cid:2)3.00 g vs. (cid:2)2.00 g; p ¼ .040).
