Summary

Although individuals following commercial intermittent fasting programmes consume meal replacement products during fasting days, further behavioural variables such as time of food consumption, sleep quality and duration, appetite and mood may significantly impact weight loss and intervention success. This project aims to assess behavioural patterns (dietary intake, sleep, meal timing, physical activity), mood and appetite on both fasting and non-fasting days and to investigate whether these are associated with weight loss.

Conditions
