About this trial

This study aims to investigate how time-restricted eating (TRE), more specifically TRE at different times (early vs late in the day), influences brain activity, behavior, decision-making, food intake, physical activity, the gut microbiome and metabolic processes. The study intervention procedure is a replication of that described in Peters et al. (2021).

Trial outcomes

Primary outcomes

1

Behaviour: risk propensity on a decision-making task

The choice (accept/reject) between a risk/gamble or safe option, based on a task paradigm by Liu et al. (2021)

Time frame
8 weeks
2

Brain: blood-oxygen-level-dependent (BOLD) signal changes

BOLD signal changes on a whole-brain level and in predefined regions of interest assessed using fMRI

Time frame
8 weeks
3

Behaviour: Daily food intake

Self-reported food intake, recorded via FoodApp or handwritten food diary

Time frame
8 weeks
4

Large Neutral Amino Acids (LNAAs)

Blood samples

Time frame
8 weeks

Secondary outcomes

1

Questionnaire assessing sleep quality

Assessed by the Pittsburgh Sleep Quality Index (PSQI, Buysse et al. 1991). The questionnaire is scored between 0-21, with a higher value indicating worse sleep quality

3

Sleep Efficiency (SE)

Assessed through an ActiGraph device

Time frame
8 weeks
4
