Main trials
HEART, STAGGERED
Participants were instructed to consume 250 mL of plain water before arrival at the laboratory between 08:00 and 08:30 having fasted overnight for at least 12 h. Body mass and body fat percentage were measured at the start of each trial using bioelectrical impedance analysis (Seca Ltd, Hamburg Germany). After 20 min of seated rest, participants underwent a baseline fMRI scan for the assessment of CBF and food cue reactivity. Baseline fMRI scans were staggered to start at either 08:45 or 09:30 and participants were scanned in identical time slots for both trials. After the baseline fMRI scan, participants rested in a semi‐supine position for 60 min in the control trial or ran for 60 min at ~70% of their peak oxygen uptake during the exercise trial. Heart rate was monitored continuously during exercise, and breath‐by‐breath exhaled gas samples were measured in both trials to calculate the net energy expenditure and substrate oxidation during exercise (Frayn,
