Digital Health Innovation
- FiberMore is a generative AI-based mobile application designed to improve dietary fiber intake through personalized nutritional guidance and behavior-change support.
- This study evaluated its impact on dietary fiber consumption and glycemic control in adults with T2D.
Methods
- Single-blinded randomized controlled trial involving 70 adults with T2D.
- Participants were assigned to either the FiberMore intervention or a control group receiving sham salt-reduction education.
- The intervention lasted 12 weeks, followed by a 12-week observation period.
Key Findings
- FiberMore significantly increased dietary fiber intake compared with the control:
- +7.3 g vs −0.9 g.
- Between-group difference: +8.2 g (P<0.001).
- This represented a 64% increase in fiber consumption.
Glycemic Outcomes
- HbA1c decreased by 0.35% in the intervention group compared with 0.14% in the control group.
- The observed HbA1c reduction was consistent with predictions from published fiber dose-response models.
Role of AI-Driven Behavior Change
- Greater engagement with AI-supported goal setting, barrier identification, coping strategies, and dietary education was associated with higher fiber intake (P<0.05).
Clinical Implications
- AI-enabled mobile platforms may offer a scalable approach to improving dietary behaviors in T2D.
- Personalized feedback and behavioral support can help bridge gaps in nutritional self-management.
The FiberMore app significantly increased dietary fiber intake and was associated with improvements in glycemic control among adults with T2D. These findings support the potential of AI-powered digital tools to enhance dietary management and behavior change in diabetes care.
