Composition of Meals Around Exercise Session

This will be a randomised cross-over study where participants will be asked to undergo screening session followed by submaximal exercise test and then undergo 2 experimental trials, one high CHO trial and another high fat trial, each lasting over 2 days. On Day 1 participants will consume either high CHO or high fat evening meal and on Day 2 they will be exercising for 60 minutes in the fasted state and then consume either high CHO or high fat morning meal and then 5 hours after morning meal ad libitum buffet meal. After this, they will leave metabolic investigation room and will record all food and drinks consumed during the rest of the day. The washout period between the trials will be at least 7 days. Prior to each of the experimental trials, participants will be asked to avoid consumption of coffee and alcohol for the duration of 2 days. All data collection will all take place in the metabolic research unit at New Lister Building (NLB), Glasgow Royal infirmary (GRI).
