Summary
A new dental device, the DDS System, significantly reduced daily food intake by over 500 kcal in adults with overweight or obesity. This weight loss intervention did not affect hunger or satiety ratings.
Area of Science:
- Behavioral science
- Dietary interventions
- Medical devices
Background:
- Reducing bite size is a behavioral strategy for weight management.
- A novel dental device, the DDS System, was developed to reduce oral cavity size and thus bite size.
Purpose of the Study:
- To test the efficacy of the DDS System in reducing food intake.
- To evaluate the impact of the DDS System on subjective hunger and satiety.
Main Methods:
- A proof-of-concept study involved 32 adults (BMI 27-40).
- Participants were randomized into experimental (DDS System) and control groups.
- Food intake and visual analog scale ratings for hunger/satiety were measured over two days.
Main Results:
- The experimental group consumed significantly less (p < 0.05) on Day 2 (M = -659.2 kcal/d) compared to the control group (M = -125.9 kcal/d).
- No significant differences were found in visual analog scale difference scores between groups from Day 1 to Day 2.
Conclusions:
- The DDS System effectively reduced food intake during meals.
- The reduction in food intake was not linked to changes in perceived hunger or satiety.
