Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Intermittent fasting

Three "fasting" days a week, whereby participants consume 600-800 kcal/day from 4 meal replacement products: breakfast, lunch, a snack and dinner. During the other 4 non-fasting "smart" days each week, participants are instructed to consume 2 x 300 kcal meals and 2 x 100 kcal snacks, from a selection of recipes, plus one meal of their own choosing.
