Cognitive behavioural therapy for insomnia (CBTi) significantly improves self-reported sleep duration and quality in overweight adults.
CBTi reduces cravings for sweet and savoury foods, improving food craving control and shifting implicit food preferences.
Objective accelerometer data showed no significant differences in sleep duration or efficiency, suggesting subjective improvements may precede measurable changes.
No clear evidence found yet for changes in actual dietary intake post-intervention, possibly due to under-reporting and limited sample size.
