Effects of continuous glucose monitoring on dietary behavior and physical activity: A systematic review and meta-analysis
Authors' conclusion
These findings suggest that CGM may facilitate healthier dietary behaviors through real-time, individualized feedback, though its effects on physical activity are limited.
Study context
- Population
- Adults with T1D or T2D, overweight, or obesity; six databases searched up to May 3, 2025
- Participants
- 1,488 adults21 trials
- Comparison
- Continuous glucose monitoring (CGM) vs control
- Outcome
- Dietary behaviors and physical activity
Pooled result
As reported in the abstract
- Significantly lower proportion of energy intake from carbohydrates with CGM vs control
- No significant differences in total energy intake or proportions of energy from fat or protein
- No significant improvements in sedentary time or time in light or moderate physical activity with CGM
Further pooled results
Pre-post analyses within CGM groups
- Significant reductions in total energy intake and changes in macronutrient composition
