Circadian distribution of carbohydrate intake during adolescence and association with risk markers of type 2 diabetes in adulthood-the role of chronotype.

This study uses a robust randomised controlled trial design. The intervention is explicitly theory-driven, targeting both behavioural and physiological mechanisms associated with post-COVID syndrome (PCS), which enhances its conceptual and clinical relevance. The inclusion of a formal health economic evaluation enables assessment of the potential cost-effectiveness of the intervention within National Health Service, supporting its translational value.
